Active cooling system

LED lamps are more efficient than traditional light sources. However, LED light sources generate a lot of heat in some cases. Generally speaking, the colder the environment, the higher the light output of the LED. Higher temperatures usually reduce light output. In warmer environments and higher currents, the temperature of the semiconductor element increases. The light output of an LED varies with its temperature at a constant current. Good and efficient thermal management helps to reduce heat accumulation inside and around the LED, which significantly prolongs its lifetime, increases its light output and minimizes the temperature impact on the shooting site.

The SD series is designed with multiple heat sinks and heat conducting copper tubes, which can greatly increase the air contact area, maximize the heat conduction to the outside, and improve the heat dissipation efficiency.

In addition, when the ambient temperature or the total heat generated by the LED is very high, we can increase the total heat from the device by forcing air to flow through it. Dual fan system allows air convection to maximize air circulation. Adding a fan also has the added advantage of removing any concentration of still hot air (hot spots) so that the entire LED system can remain at a reasonable temperature for a long time.

Locking Yoke

A re-designed yoke construction accommodates an expanded range of motion with over 330 degrees, letting you angle and point your light anywhere needed. An improved user-friendly handgrip design also allows for highly intuitive controls.

Ultra-silent design

With the carefully designed mute system, the GVM-SD series has boldly introduced a new design, with a built-in cooling super-mute fan. The advantage of the dual fan is that it can effectively cool down without requiring a high speed. With 100% light intensity, the noise will not exceed 40dB even if the two fans rotate at the same time (when the ambient noise is less than or equal to 22dB). Almost no sound can be heard, and there is no need to adjust the lighting position to accommodate the noise.

Durable transport case

The GVM-SD300S comes standard with a durable carrying case. And all its major components can be stored in the case . The thick case effectively protects the lamp body and accessories for easy transportation and safe storage.

    The knobs and buttons both feel good, although I did find that if I had to go from one end of the scale to the other, it took a lot of turns to get there. The good news is that it can be linked to other lights so I can control all lights from one master. It even has app controls to make it even easier.

    The main body of construction is metal and plastic. The metal requirements for the heat dissipation area are higher.

    Have no complaints.

    At 100% output, I can do it 6 feet away with lights without modifiers. Shot with my Sony A7Siii in Slog3.cine. Shutter 1/50 ISO 640 is a bit brighter than f/11. Colors seem to be fairly accurate, probably a warm 300 Kelvin. Compared to the Apture 300X, it looks very similar in terms of color and brightness. I got an exposure of F/10 at 5600K.

    It has a diffuser cap. I’ll have to check it out if it’s protecting the LED chip during travel (protective cover not included) or if it’s a diffuser. I’m a little scared to use it because the chip gets hot during use. I might just use it for travel protection.

    The display is large and easy to read. It does get darker at steep angles, but it’s still easy to read.

    Reflectors are great. It really focuses the light and lets you get some extra output out of it. Much better than most 7″ reflectors that come with these lights.

    Operation and dials are very intuitive. You turn the “BRG” dial and it will adjust the brightness level. You may need to adjust it by switching the Mode to Rotation. Otherwise, you are in master/slave mode. I want to have only one master/slave switch with all modes. But not the boss. DMX requires an adapter (not included) – but won’t show up on the schema until the adapter is plugged in.

    I was curious and bought it as an option for photography.

    Color accuracy is not exactly the same as the LED screen on the back of the lamp. A true 5600K is closer to a 6800k – 7000K. As long as you know this and adjust, it shouldn’t hold you back too much. The lights are a bit magenta, but not overpowering and easy to correct in post.

  11. 5 out of 5


    Build quality is very good. It’s a plastic-type material, but it looks and feels well done. There are some metal parts (watch out for heat). I think that’s a benefit of dealing with heat.

    While a lot of people love to hate that GVM products aren’t “professional,” this 300W COB light and many of their other products are just as good as their big-name competitors. I’m no stranger to GVM lights. I have a set of their 75 watt panels and they are great considering the price point. This 300W COB is as good as the Apurture 300x in terms of features (Apture wins in design and build, but at 2.5 times the price). The light output is excellent – very bright – but considering it’s dimmable, I’d rather go for very bright as I often use it with two layers of diffuser. And the advertised 5600k color temperature is dead. One of my complaints is the power pack, it doesn’t have a way to hang it on the light stand, and it’s too heavy to hang. I glued a 3-M hook through the gorilla and attached a loop of thin wire so I could hang it from the tension knob on a light stand, like an Aputure power supply, but with the exception of the slight Annoyance aside, my jury came up with a solution. , otherwise the light is perfect. As far as fan noise goes, it’s quiet enough for almost any application (especially considering it’s so bright that you can place it away from the mic rather than a low-powered light). With proper placement and use of a shotgun mic, it’s nearly silent. This light is very good value for money.

    It comes with a diffuser and a reflector so I can use it out of the box. I like to use it with a large reflector disk for beautiful, full lighting.

  14. 5 out of 5


    It also comes with a nice travel/storage box. It will keep everything together nicely.

    This budget lamp is a great option when you need a lot of light output. There aren’t really many lights on the market, and I honestly can’t think of a price with that much light output.

  16. 5 out of 5


    Overall a fantastic light. highly recommended.

    Most LED video lights you see are 60w. Maybe 120w sometimes. This bad boy is 300w. It was crazy bright. This is handy if you’re shooting in an area with some ambient light, using large modifiers, or if you have to keep the light source away from the subject. I’ve been in a few situations where using a 300 watt light would have made the job a lot easier.
