DIYP is reviewing Sirui Dragon Flexible LED Light Strip

The LED photo and video market has become quite commoditized. Having CRI (95+), either RGB or white LEDs, or an application is not enough to compete in the market anymore. This is why brands tend to fight over either price, quality, and service or, more interestingly, over features and innovation. Entry Siroy Dragon LightRGBWW LED strip is bendable and app controlled. While this is not the first bendable light (see KYU-6), it is the first large, high-output flexible light. And the this is Worth a look.

Sirui is famous for its excellence tripod line and his anamorphic lenses, so it’s interesting to see how their knowledge of other imaging lines will translate into the LED industry. And right away, you can see that it’s not a tube, it’s not a plate, it’s not COB, it’s something else entirely.

in the box

We received Monday group of lights Which is $399And the It includes the following items:

  • Two Sirui Dragon LED Flexible Strips (This is the main part of the product)
  • Two standard 8-digit power cables
  • 100V-240V Universal Power Supply Brick
  • Two ARCA-swiss compatible panels.
  • Mounting bracket: one bracket is like a rotating one and the other is suitable for two LED strips
  • Evidence

Siroy Dragon LED Light - In the Box

There is another smaller group with One light for $199-If you don’t want to commit as much.

Everything, the light is well-built, and the arches are Sirui’s signature “tank quality.”

What is LED dragon light?

Good question. I was wondering the same thing. Actual likes were created from nine panels (or metrics if we stick to Dragon terms). There are seven short LED panels in the middle and two large LED panels on either side. One of them is the control panel and power. I can see why Sirui called it the Dragon Light. The light kinda looks like a Chinese dragon – these Tall snake shaped creaturesUnlike our western dragons.

Sirui Dragon Led Light - Back Side

Each two panels are connected by a hinge. It is not easy to move, but it stays in place once you move it. This is the mechanism that gives light its dragon tale-like flexibility.

Each unit contains a combination of warm white, cool white and RGB LEDs. (Hence the acronym RGBWW LED). The combination of these five variables gives a lot of control over the light, but I’ll get to this later.

banding panels

The last panel – the tail – is the control panel, which is slightly different from the rest of the panels. This is where you can plug in the power, control the lights, and turn them on or off. Generally, each strip is about 58cm x 7.5cm (or about 23 x 3)

Dragon Light – Bendable and Installable

Obviously, the most interesting feature of the Dragon Light is its ability to bend. The dragon light bends in an interesting way. If you bend the light back, you get an arc that sheds light over a larger area. It bends about 30 degrees, which makes it a good application when you need to cast a wide light. A green screen or a white background are two very good examples where this feature comes in handy.

If you bend the light in the other direction, it bends more and creates an almost semi-circle with all the panels facing the center. This is an interesting solution if you need to illuminate a product from more than one side.

To make things more interesting, you can connect the two strips with one 120 cm long strip. This is a serious strip light power and can be a great side lighting application.

Each end of the Dragon Light has a small 1/4-20 socket for vertical mounting, and there is another bracket kit that allows you to mount the strips side by side to create a large, bendable panel. This is a good reason to go to the larger group if you can afford it.

Energy

There are two ways to turn on the light:

  • with one NPF . battery or
  • With 9 volt power brick
  • There is a small rocker switch to choose between the two.

If you choose the power brick, it comes with a 150cm line which should be fine as long as you don’t mount the light too high. unlike Speckular lightswhich can also be combined, energy is not transmitted between partitions

Although, we had some issues with battery operation. Getting the battery in and out wasn’t as smooth as we’d like it to be. It required more “oomph” than we’d like. The other bigger problem was that the NPF batteries (or at least the few brands and sizes we tested) didn’t provide enough juice to drive the light at full capacity, and the light turned off. This can get frustrating very quickly.

light quality

Regarding the quality of light, today’s environment is sensitive to several factors: brightness, CRI value, color temperature accuracy, and a green-purple shift. Let’s take a look at each of these factors. I’ll put a table of our measurements at the end of the post.

Regarding CRI, we are very pleased with the results. We tested 100%, 50% and 25% power across multiple temperatures. Among all the tests, the CRI fell slightly below 95 for low brightness at 3200K. That’s for sure Good enough for any shooting scenario I can think of.

The color temperature was spot. Aside from the extreme edges, the delta between the measured CCT and the actual CCT was pretty low, at least not to the point you’d notice, and certainly on par with other LEDs in this range.

For brightness, please have a look at the table at the end of the post and gauge if that is enough for you. The Dragon light is rated at around 25 watts, which is very little light. It’s also competitive when you look at watts per dollar. The Amran F7another panel, produces about 15 watts and It costs $98. Both lamps are at roughly the same watt/dollar ratio, with Dragon being slightly more expensive per watt. As far as usage goes, the Dragon Light won’t compete with the sun, but it’s more than enough at close range in controlled environments.

I couldn’t measure the green-purple shift. I can say, however, that there is a setting where you can adjust the light to match other lights. If this is something you care about, you should know that it can be controlled, but I didn’t have the tools to measure its accuracy.

control

There are two ways to control the light: a set of four buttons or an app. The control system is very similar to other RGBWW lights. It also has the same set of features you’d expect from a video light in 2022. You can adjust the light via several modes: RGB, HSI, CCT, and Effects. For each mode, you see the submenu and you can control the selected parameters. If you have physical access to the light, this is a very convenient and proactive way to control it.

The only thing I wish the controls would support is the control of several connected lights from a single unit. (In a similar way to stellar lights). Unfortunately, the connection between several units is only mechanical.

The other way is via the app. We had access to a pre-release app. It got disconnected every now and then and wasn’t a full feature. We’ve seen a fair amount of issues with getting data from the light, controlling several lights, etc. If you take bugs out of the equation, the app has everything you’d expect, including access to all the controls you have in the physical menus, grouping of lights, etc.

Dragon Light tests in the real world

We used the light in several shots and tests and this is what we found out. The light bends, which is definitely a great feature. Whether this works for you depends on your needs and the specific settings you’re picking up. For some, bending is a lifesaver; For others, it has very little effect.

Check out these two images, for example (using a highly reflective 3D shot of Thanos). You can scroll to see the differences. The image on the left has an inward curved light, and the image on the left has the light as a “standard” strip light. what do you think?

However, being a bendable light can work magic as a practical light.

But even without taking bendability into account, it performs incredibly well as a tape. The fact that you can connect two lights with a long strip or greasy plate is significant in itself. Sirui quality is shown on the brackets and accessories.

Here are more pictures to show how the light performs.

conclusion

Sirui Bendable LED Dragon Light brings something new to the market. It’s great to see companies innovating in this very saturated market. As an LED panel, the Dragon performs very well. It’s smooth, has a distinct light signature, and has a form factor that can work in many shots. With this in mind, the Dragon is indeed a good light and very affordable for what it is. If you need the extra bendability, buying this light becomes a no-brainer.
