The VL-D640T Bi-Color LED Light Panel from Viltrox is made with 40 high-efficiency Bi-color LEDs to provide a versatile, adjustable light output. With a high CRI of 95, the VL-D640T renders colors and skin tones with high accuracy, anywhere through its flicker-free dimming range. The included 4-leaf barndoor allows the light beam to be directed and flagged to control spill or highlight the subject.

The panel's sturdy but lightweight plastic construction provides both durability and efficient convection cooling, so the fan-free panel is fully silent and suitable for video-based applications where live sound is recorded. The lightweight design is easy to pack and travel with, across town or across the world.

Related Questions and Answers

Q: 1. Can you run this light on one battery or do both need to be on the light?

A: You will need two NP-F batteries inserted into the Viltrox VL-200T Bi-Color LED Light with LCD Display and Wireless Management for it to work.

Q: 2. What is the difference between these lights and the 520S-B?

A: The 520S has a larger and more robust frame.

Q: 3. Does it provide WiFi access or just wireless controller? WiFi is a term reserved for IEEE802.11 so if that is not the case the name is misleading!

A: This comes with a wireless remote control, not WiFi.

Q: 4. Does it come with a bag or a carrying case?

A: A case is not included with this light. We recommend BH #POPBLED7100T from Porta Brace for it. https://bhpho.to/2RiOAK4

Q: 5. How do I turn this down past 25%? The specs say it goes from 10% - 100% but using the knob or remote it won't go lower than 25%.

A: It can be turned down to 10% when set to 5600K using the back dial, and perhaps at other color temperatures as well, and while using the remote. There are YouTube video reviews that show users doing that. I apologize if that's not true of yours, and if it is then I would recommend that you please contact customer service.

Q: 6. Does the housing for this light have a 1/4x20 threaded female attachment?

A: Yes it does. There is a 1/4"-20 threading under the light.

Q: 7. This light comes with color filters?

A: The Viltrox VL-162T Bi-Color LED On-Camera Light comes with Diffusion Filter, it does not have color filters, but it is Bi-Color which means you can change color temperature from 3300K to 5600K on fixture itself. You can purchase color gel filter separately https://www.bhphotovideo.com/c/accessories/Color-Gel-Filters-for-the-Viltrox-VL-162T/1459176-REG-47508

Q: 8. Can this be mounted on a tripod?

A: Yes.

Q: 9. Will the included mount attach to a standard light stand or do I need another attachment?

A: The included mount will directly connect to a standard shoe mount or using a 1/4 20" thread... Some smaller light stands will allow you to mount the light directly on them, while some have larger ones will have larger mounting threads, thus an additional accessory would be recommended... Following is a link to an introductory selection of potential options https://bhpho.to/35w4ypa

Q: 10. Is there a way to reduce the brightness lower than 20%? Is there a diffuser that I can place over the front of the panel to reduce the light intensity? I am using this for Skype and Zoom; I'm about 30 inches from the panel.

A: The dimming function on this unit should achieve the desired result, as it can dim down to about 20%.
