Flex Light Review

Remember the first time you heard about a flexible LED panel light? You were probably a little bit impressed, or maybe even enthralled. So now that flex lights have been around for a few years, why hasn’t every videographer or documentary filmmaker on the planet bought into them?

Imagine, an LED light that has the power and color quality as an industry standard Litepanels 1x1, but weighs mere ounces, is thin enough to be rolled up or lay as flat as a magazine, is flexible and can be shaped to fit around tight spaces, and is durable enough to be used outdoors in the rain.

TL;DR: Genuine Flex Lights are amazing, but they're still costly and missing a few key features that would make them worth getting. However, cheap, Chinese knockoff flex lights are now a thing, and we recommend the Falcon Eyes RX-18T for videographers who want to try a flex light today.

Our recommended flex light hanging on a wall

If you’ve ever carried around one of the original Litepanels 1x1 lights, you know how beastly they were. And once you added a V-lock battery on the backplate, you had a piece of heavy metal on top of a travel light stand. And for a simple interview shoot, you probably needed two or three of them.

Nowadays, we have a lot more options to choose from when it comes to LED panels. We have small, but powerful LEDs like the TorchLED Bolt that can be made into a large panel with a portable softbox, we have LED Fresnels like the Aputure COB 120D that are compact yet powerful interview lights when used with a scrim or umbrella, and we have extremely lightweight plastic panels like the Aputure Amaran lights, which offer a lot of power at the expense of durability.

But if you want a solid, dependable 1x1, you’re still looking at heavy duty housing. Even the widely popular Aputure Light Storm LS1S, for example, is still about 11 pounds with all its fixings, plus the battery.

If you’ve ever seen LED strips on their own, you’ll wonder why it takes that much heavy metal to support a ribbon of LED bulbs that weigh no more than the ribbon you tie your birthday gifts with.

Sure, there is heat management, power supply, on-board dimming or color tuning, plus extras like a yoke, barn doors, battery tray, wireless dimming control, and general damage protection.

But what would happen if you placed a few strips of LED ribbon on a soft backing, and wired all the dimming and power to a remote unit?

That’s exactly what the Flex Light set out to become. First introduced to a small professional filmmaking audience by Korean manufacturer Aladdin, called the Flexlite 1, it was then adapted by Westcott into the Flex Mat and marketed toward a much larger market. And although many who own one have raved about it, you still don’t see a lot of Flex lights out there being used by everyday videographers. Why is that?

westcott-flex

It turns out it’s the little details that have held back many buyers from handing over their wallets (and their current lighting kits). But mostly the cost. With a diffusion screen and a battery, you're looking at over $1000 for a 1x1 flex light. Which is maybe not that much for a traditional light panel with heavy duty housing and advanced features, but it's harder to swallow when you know that a few ribbons of high CRI LEDs can be bought for $25. 

Fast forward a few years later, and now there’s Chinese Flex Lights that sell these cheap LED ribbons in flexible housings. Some even look remarkably like the original Aladdin and Westcott Flex. Sure, they don't have the build quality of an authentic Flex light, but they're much more affordable. So we decided to buy a few of them to try them out. And to our surprise, they’re actually pretty good. So now, the details.

Flex Light: What it is and what it should be

If you’ve followed this site for a bit, you may have read about our attempt to make a DIY Flex Light earlier this year. We figured it was worth a shot, even if we failed, just to learn a little about DIY electronics.

Our attempt at a DIY flex light

Well, it turns out we don’t have the gift of soldering, so after several attempts, we failed. And it ended up costing quite more than we figured for all the supplies that we didn’t already have, like a temperature controlled soldering iron, the various heat-resistant glues, faux leather, and more LED ribbons than we initially thought we needed.

In the end, we realized we were spending too much money and time on the project, so we decided to scrap it. But the bigger lesson was that even if the DIY version worked, we really wouldn’t feel comfortable depending on it for paid gigs. So we decided to put away our DIY electronics dreams and just stick to buying lights that are manufactured and ready to use.

A few months later, we started hearing about Chinese knockoff flex lights on Alibaba, Aliexpress, and even Amazon. They looked pretty decent, but knowing that they were probably a bit underpowered compared to the original flex lights, we weren’t as interested in the 1x1 versions. We waited for bigger mats - we wanted a manufactured version of the 24x18 inch version we tried to DIY, or larger, like the Westcott 2x2 mat. (More on that in a bit..)

At NAB, we got to see where the flex light industry has been moving toward since its introduction a few years ago. And to be honest, most of the professional grade flex lights out there are kind of veering away from the whole reason why we were enamored with flex lights in the first place - their size and weight.

flexible-led-strip-interview-light

We've been using our recommended flex lights in place of traditional panels

For us, we’re not that interested in wrapping a flex light around a pole, or sticking it inside a lampshade, or any of the other creative uses for it that are mostly marketed toward narrative filmmakers. We simply want one because they take up no space or weight during travel. Even if we only attached them to a light stand for use during interviews, we would be happy to chuck all our other lights when we’re traveling on documentary shoots.

The secondary use for flex lights is to be able to tape them onto walls or ceilings when we need a simple B-roll light off frame. There are plenty of times where we’re shooting a subject working on something, and instead of setting up complicated lighting arrangements, it would be so nice to just tape a flex light directly above the subject, or against an object or wall nearby.

flex-light-ceiling-overhead-table

But for some reason the industry has not gone in that direction at all. Instead, we’re seeing flex lights being sold with accessories such as rigid frames and heavy-duty, solid metal housing, turning them into what look like traditional 1x1 panels.

We’re seeing flex lights marketed for their waterproof durability in extreme outdoor situations, rather than the fact that they are super convenient for most simple, indoor interviews and shoots. And we’re also seeing large multi-unit systems that enable you to build large sources of lights, using a series of 1x1 flex mats in a variety of configurations.

aladdin-flexlite

All of these applications are very interesting, and they do still take advantage of the flex light's portability, to some respect. But for the everyday videographer, the main issues with the original Flex light still haven’t been addressed, which would make them a no-brainer purchase for many of us.

First, the dimmer and power brick is still fairly bulky on all the flex lights out there. If you want to tape the light onto a ceiling, for example, you would need to have a long extension cable to ensure that the dimmer unit isn’t hanging in mid air. One of the reasons we were really interested in the DIY flex light is because the dimmer itself was about the size of a matchbox. The AC brick is still as big as any AC power unit out there, but you could place that far from the light itself.

kamerar brightcast flex light

But really it’s the battery issue that has prevented the flex light from taking off. None of the flex lights out there have a simple method of attaching a couple Sony NP batteries on the back.

They are tiny, cheap, and lightweight - the perfect companion to a flex light. But the only advertised battery option for flex lights out there are bulky and expensive V-mount and Anton Bauer batteries.

Actually, Brightcast/Kamerar initially offered a velcro Sony NP connection to the back of their flex lights, which was one of the main reasons they got a lot of attention.

And while it was still a little clunky, it was very close to what many people wanted. But for some reason, they’ve moved away from that battery back and toward the big battery bricks instead.

And then there are the softbox diffusion options. Again, for some reason flex lights have been paired with softbox diffusion systems that take away from the lightweight and thin nature of the flex light itself. Sturdy, dependable softbox diffusion kits are great, but if they take up more space than the light, and take more than a few minutes to setup, then they’re kind of missing the point.

And finally, as much as we like the 1x1 panel, flex lights allow us to think about bringing bigger lights around with us, like 1x2 and 2x2, without adding any more space. They can simply be folded or rolled up for travel, so why wouldn’t we want the bigger versions instead? A traditional 2x2 metal-frame light panel would be so heavy it would require a C-stand and sand bags.

Aputure Amaran next to an RX-18T 18x24 flex light

That’s why the large flex light is such an attractive product. It gives us something we can’t get otherwise. Whereas when you compare a flex light with dimmer and power brick, it ends up being heavier and more copmlicated than a simple Aputure Amaran 672 with a couple Sony NP batteries.

One more point to consider. Most 1x1 flex lights offer around 250 LEDs in a variety of beam angles and wattage. The power output can vary quite a bit with those differences, but still, the number of LEDs is a good base to use when you’re shopping for lights. Comparatively, the Aputure Amaran 672W light has, you guessed it, 672 LEDs.

Both the Westcott Flex 1x1 Daylight Mat and the Aputure Amaran 672W lights claim around 2000 lux at 1 meter. The Amaran has a power draw of 45W, while the Flex has 55W, which makes sense since the Amaran takes two Sony NP batteries and the Flex requires an additional battery brick to power without AC. As for beam angle, the Flex claims 140-360 degrees, while the Amaran 672W is about 75 degrees.

At any rate, the point is, here are two lights with roughly the same photometric output numbers, but one has 256 LEDs and one has 672 LEDs. So that’s another thing to consider when we’re looking at Flex lights. What’s more important, a super bright mat with a big dimmer plus battery box, or a compact package with less output per LED, but ultimately more portable?

Flex Light Chinese Knockoffs

At last we get to the Chiinese knock off flex lights. For those looking at 1x1 alternatives, the most popular versions have been:

  • Kamarar/Brightcast V15 Flexible Bicolor LED Panel - this was the first knockoff flex light, so it's a little more developed and has unique features like a battery plate that velcros on the back of the light. They used to include a Sony NP battery plate, but now it's only the larger battery bricks like  V-mount. It's also pretty expensive, and at the price it's probably better to go with a real Westcott Flex.
  • Samtian FL-3030 - the same light also sells under different names, such as Eachshot, Andoer TravorFositan, and Neewer. This is the closest thing to a copycat of the Flex, at a fraction of the price. But of course, don't expect the best quality.

But like we wrote above, we are interested in the larger flexible LED mats, because they offer a unique large source of light that would otherwise be too bulky on a traditional panel. And also, more LEDs mean more output, for not much more cost, so we think the larger mats are a better bet. The sweet spot is a larger mat that doesn’t require a huge, bulky dimmer or power brick. Here are the popular ones:

  • Samtian FL-3060 - this also sells under different names, such as Andoer Travor, and Fositan. It's basically a 1x2, or around 12x24 inches, with 448 LEDs at 85W of power, with a 120 beam angle. It comes with a remote, carrying case, light stand adapter, and a diffusion frame and cloth. Overall it's a much better deal, with twice the output as the FL-3030 without adding much to the size, since the accessories are the same, and the mat can be rolled up or folded.
  • Andoer Travor FL-3060A - this also sells under Fositan. It's exactly the same light as the FL-3060 except bicolor. So with the same amount of LEDs and power supply, you're getting half the output in daylight. But bicolor is pretty convenient. While we wouldn't do bicolor in the 1x1 size, we would get it in this 2x1 size.

Although we really like this 2x1 version, especially considering the price, there are a few things that kept us from buying it. Like the Westcott Flex, the diffusion cloth attaches to a scrim frame, which takes a little time to setup. Not a big deal, but it still only sits an inch or less away from the LED face. So, it’s not that effective at spreading light. It’s probably easier to just velcro the diffusion cloth to the light and call it a day, if you want to cover up the individual LEDs for a little amount of diffusion. 

Mostly, it’s the lack of a battery mount that makes the FL-3060 and FL-3060A a not particularly attractive option for us. But the build quality, remote, and overall crazy low price makes it an easy purchase even if you don’t end up using it all that often.

Falcon Eyes RX-18T and RX-18TD

Finally we get to the lights that we bought and recommend. Actually, we got them at NAB under a different name - Soonwell - but they’re completely identical, and Falcon Eyes is the name that’s available on Amazon.

flexible-light-photography-video

The Falcon Eyes RX-18T is a daylight mat roughly 18x24 inches across, and only about 10mm thin. It draws 62W of power, with an advertised 792 LEDs at a very wide beam angle (the specs say 10-360 degrees, which doesn’t really make sense, but oh well). It claims 2500 lux at 1 meter.

Strangely, we only count 504 LEDs, so we’re not sure where the 792 number comes from. 

It has a much less rigid frame than other Flex lights, which we actually like, because it’s a lot easier to roll up tightly for travel, and as we mentioned before, we’re not really going to wrap this around a light pole or something.

flex-light-support-bracket

Because it’s not very rigid, you can’t simply clip it onto the top of a light stand like you could with other flex lights, so you need to use the included support bracket with a baby stud light stand adapter built in.

It’s not bad, perhaps a little better than Westcott’s original support bracket, and it’s quick and easy to setup. But the light stand adapter rotates freely, and is not tightenable, which means sometimes the light tilts a little toward the side where the AC adapter plug is pulling on it.

flex-light-softbox-diffuser-bracket

The support bracket is a single solid piece, and it's as long as the flex light is diagonally and doesn’t break down into smaller pieces. Overall, it works, but we’ll be looking at a simpler DIY solution to mount this to a light stand in the future.

Speaking of diffusers, one of the things we most like about this light is the custom softbox diffuser, which you can get on its own or as a kit with the RX-18T. It is super easy to velcro on, does a good job of diffusing the light, and what we like best about it is it makes this Chinese flex light knockoff look like a decent 18x24” panel light to the client or subject you’re interviewing.

flexible-led-panel-light-softbox-diffuser
flexible-led-panel-light-honeycomb-grid

The softbox also comes with a honeycomb grid, which is a nice bonus, but we’re not sure if it makes that big of a difference in controling spill. There’s also an interesting looking half-sphere diffuser included in a different package, but ours didn’t come with one, so we can’t comment on how good it is.

Our one complaint about the softbox is it doesn’t fold up as compactly as we’d wish - it ends up being longer than the 24-inch side of the flex light. Folded up, the softbox and the support bracket both take up a lot more space than the flex light itself, which is not very convenient for packing.

fledxible-led-panel-battery-power

Finally, the key to our choosing this light over the others is the dimmer box is really small, and it includes a V-mount tray for batteries. This really is the most compact battery solution we’ve seen for flex lights yet, and even with a 160W V-mount it’s still very portable and convenient. The dimmer box includes a little plastic hook that makes it easy to hang it from a light stand knob.

Our recommended flex light on an interview

We’ve been using this light on a variety of shoots, and it’s actually pretty good. With the softbox on, it ends up being a pretty large source of soft light that makes for a good key light. We think the color and output matches well with daylight coming through a window.

We’ve also used the light as we originally dreamed about using a flex light for, to mount on a wall when we need a simple light for B-roll, or to hang from the ceiling when we want an overhead light. 

flex-light-gorillapod-mount

We actually bought two of the RX-18T lights, and one of them ended up having a few missing LEDs on one strip. The company we purchased from - Soonwell - sent us a replacement strip, along with video directions on how to solder it together. But knowing our shoddy soldering skills, we’d rather have a functional light with a few less LEDs, than have to send the whole thing back for a replacement after a botched soldering job.

Apart from the missing LEDs on our one unit, just about the only complaint we have about the RX-18T is we wish it was a little brighter for a 18x24 light. The Westcott 2x2, for example, has twice the amount of LEDs, at 3x the wattage, so it has about 3x the output. But it's also 10x the cost.

Compared to a typical 1x1 panel, the fact that the RX-18T’s beam angle is wide and it’s a larger source of light means you don't need to heavily diffuse it to make it softer. By the time you diffuse a standard 1x1 panel through a 5-in-1 portable diffuser, you've lost half its light output.

Falcon Eyes RX-18TD Flex Light

The RX-18T is available in either daylight or tungsten only, but it also has a bigger brother, the RX-18TD Bicolor, which features the same overall amount of LEDs but with a higher power draw of 100W. For some reason, even at 5600K, the RX-18TD is rumored to be brighter than the RX-18T. So, you should just get that one, right?

Everything apart from the power supply is exactly the same as the RX-18T, so we’ll focus mostly on the power supply. What it comes down to is, the dimmer box is gigantic. It’s about 3X the size of the RX-18T’s dimmer box.

The RX-18TD is bicolor from 3000K-5600K so they could have just added a color adjustment wheel. But instead, it’s an LCD screen with a small computer inside that allows you to adjust both output and color with touchscreen controls. There’s also wireless control via DMX.

RX-18T dimmer and V-mount battery on the left, RX-18TD dimmer on the right.

Even before looking at brightness levels, we think the RX-18TD’s dimmer unit makes it a lot less convenient for lightweight travel. The AC adapter is also bigger than the one included with the RX-18T. If you want or need bicolor, then sure, it’s a good buy. But if you’re only looking at daylight, then the RX-18T is your best bet.

Side by side, when we turn on both the RX-18T and RX-18TD to full power daylight, their outputs don’t look very different. The LEDs on the RX-18TD are actually slightly bigger, and with the higher power draw from the dimmer unit, the output is higher, even with only 252 LEDs activated, compared to all 504 LEDs on the RX-18T.

flex-light-bicolor-vs-daylight

We also connected the bigger dimmer onto the daylight RX-18T to see what would happen (we’re crazy like that). The color switcher turned on alternating rows of LEDs, just like on the bicolor version. At somewhere in the middle of the color dial, both rows were on, and perhaps they were slightly brighter than with the smaller dimmer unit, but we couldn’t tell. So, interesting experiment but not that useful.

Conclusion

We’ve been wanting to get into Flex lights for a while now, but features like bulky dimmer and power bricks, no battery options, and the overall cost, kept us from buying into the flexible mats. Over time, the flex light industry has moved farther and farther away from embracing its simple, lightweight nature, and instead it’s moving into more complicated framing units that require multiple flex lights as their source.

So when the Chinese knock off lights became availble, we started watching for a good mix of price and features that would enable us to take use the flex lights as we hoped to use them: as simple, lightweight, portable interview lights, as well as B-roll lights we could tape onto walls and ceilings.

The Falcon Eyes RX-18T and RX-18TD is currently the best bet for these features, as they are larger mats that are incredibly light and easy to roll up, they have easy battery attachments, their custom softboxes make them more attractive as key lights, and they’re really really cheap.

But of course, when it comes to Chinese knock off lights, you get what you pay for. Sometimes that means broken or faulty products (like our missing LEDs), and sometimes that means hard to understand marketing or product information that gets lost in translation, like the 504 vs 792 LEDs that describe the same light.

In the end, we can live with the flaws, and we also know these lights aren’t much more than manufacturerd versions of our DIY Flex Light - LED ribbons soldered together and paired with off the shelf power. But we believe these lights will be dependable enough to take out in the field for at least a year, if not more, and for the price, that’s worth it.

We’ve already used these lights on interviews and for product photography, and we plan to take them back to Alaska on our upcoming shoots. We’ve also taped them to a wall and ceiling in a pinch. It’s kind of exciting to know we have these in our tool bag when we need them.
