Built for serious underwater videographers
The SUBNOX SUB10KEF is a 10,000-lumen wide-angle video light engineered for working underwater cinematographers and serious hobbyists. Unlike conventional video lights that need bulky physical blue filters at depth, the SUB10KEF uses a patented COB LED light head to switch between daylight and ambient water colors with a simple twist of a dial — giving you up to 2.5× the brightness of filtered lights.

Features
Patented ambient color technology
As you descend, water absorbs warm tones and your footage starts looking unnaturally red wherever your light hits. Traditional fixes — manual white balance or physical blue filters — either kill your background or kill your brightness. The SUB10KEF solves this with three precision-tuned modes:
- 5600K Daylight — for night dives, shallow scenes, and traditional lighting
- Ambient Blue (6–13 m) — blends seamlessly with mid-depth ambient light
- Ambient Blue (13–20 m) — matches deeper water tones for natural-looking footage with no hot red foreground
The result: your subject and background match in color temperature, requiring far less work in post.
One-handed magnetic power ring
An 11-step (0–10) magnetic control ring at the rear of the torch lets you adjust brightness with one hand, even wearing thick gloves. A 180° turn covers the full range. No fumbling with tiny buttons mid-shot.
Always know your battery life
The rear LED display shows your current brightness level, then auto-switches to remaining burn time in minutes — calculated for your selected color mode and brightness. No more guessing how much dive time your light has left.
Air-travel safe USB-C battery
The included 72Wh battery pack charges 0–80% in 2 hours via USB-C (full charge in 2h 45m) and falls within airline carry-on limits. Use a 40W USB-C charger for fastest charging (charger not included).
Burn time at full power
