Unveiled at DEMA Show 2024, the SUBNOX brand was founded by professional underwater cameraman Kay Burn Lim, with the aim of creating advanced underwater lighting products designed to meet the needs of working videographers. Now, the new company has put the finishing touches to its first offering—the SUB10KEF, a 10,000-lumen wide-angle video light with some innovative features.  

The powerful but compact video light is equipped with a specially designed light head and COB LED that produces three different light outputs. One mode is “traditional” light with a CRI of 93 and a color temperature of 5600K, equivalent to daylight. In the other two “Ambient Blue” modes, the light output is equivalent to ambient light at 6–13 meters (20–43 feet) and ambient light at 13–20 meters (43–66 feet).

As depth increases and water absorbs colors from the light spectrum, white balance controls or red filters are used to restore natural colors, but this causes subjects illuminated by regular (daylight) video lights to appear overly red. Blue filters on video lights results in more natural-looking footage by helping to balance the foreground subject illuminated by the lights and the bluish background. However, the downside is that such filters reduce light intensity significantly.

With its built-in ambient light options, the SUB10KEF provides ambient water color illumination approximately 2.5 times brighter than using physical blue filters. By covering two depth ranges—6–13 meters (20–43 feet) and 13–20 meters (43–66 feet)—at the twist of the rear dial, the SUB10KEF can be used in a variety of daytime lighting conditions as well as at night, when the 5600K (daylight) mode can be used.

The SUB10KEF features an ergonomic 11-step (0–10) magnetic power control ring at the rear, and a rear-mounted LED display showing the brightness level as you turn the power control ring. After setting the brightness level, the display defaults, after five seconds, to the remaining burn time in minutes for the selected brightness level. The video light’s air-travel safe 72Wh battery pack can be charged from 0–80% in two hours and to 100% in three hours.

Shipping late May, the SUBNOX SUB10KEF is priced at $800.
 

PRODUCT INFORMATION

SUB10KEF Wide Angle Video Light – 10,000 Lumens With Daylight 5600K & Ambient (BLUE) Water Colour

$800.00 USD

The SUB10KEF is a compact 10,000 lumens (93 CRI) wide angle video light with the patented ability to switch between a daylight colour (5600K), and ambient water colours for 6–13m or 13–20m.

Patented Light Head

With the patented specially designed light head and COB, It does not require any physical blue filters to achieve this specially tuned ambient water colour illumination. This allows the torch to be used at various depths and lighting conditions night or day. (Ambient blue is not required for night dives).

Power Control Ring

The SUBNOX SUB10KEF utilizes a large 11 step (0-10) magnetic power control ring ergonomically located at the rear of the torch. This allows for smooth, effortless and intuitive control over the brightness level.

The rear mounted power control ring is designed for one handed use in a single motion over a 180 degree turn of the ring. It is designed for easy use even with thick gloves. No more reaching over your torch to press buttons, or fiddling with tiny control knobs. Just grab and twist!

Light Colour Selector & Power Switch

The rear knob below the LED display allows users to switch between the 3 light options:

• 5600 Kelvin (Daylight)
• Ambient Blue (6–13m)
• Ambient Blue (13–20m)

The button at the center of this knob functions as the master switch for powering the SUB10KEF On or Off.

LED Display

The rear mounted LED display shows the brightness level as you turn the power control ring.

Once the brightness level is set, the display will default after 5 seconds to the remaining burn time (battery level in minutes) for the brightness intensity chosen. A simple 4 bar battery icon is also displayed for all settings.

3 different LED indicators display the current colour settings. 5600K, Ambient Blue (6–13m), Ambient Blue (13–20m).

USB-C Rechargeable Battery

The Battery pack for the SUB10KEF utilizes a fast charging USB-C controller that allows the battery to be charged from 0–80% within 2 hours (full charge from empty requires 2 hours 45 minutes) and is rated at an air-travel safe 72Wh.

Each battery pack provides enough power for 35 minutes of continuous use at maximum brightness for the 5600K light setting, or 1 hour at 70% brightness settings.

The battery pack will last for 55 minutes at 100% brightness when used with the ambient water colour settings.

For maximum charging speeds. Please use a high quality 40W USB-C charger (Not included). A high speed USB-A to USB-C cable is included.

All batteries come with silicone protective cases for travel and protection of battery contact terminals when not in use.
