Description
More output for wide-angle work. Three colour temperatures to shape the shot.
Lighting a nearby subject is one challenge. Balancing it against open blue water is another. Our Spectrum 25000 gives you both high output and a choice of light colour: up to 25,000 lumens, a 120° underwater beam and selectable 5600K, 8000K and 16,000K modes. Change the output colour at the source without fitting an external colour-conversion filter to the light.
Three modes, three ways to approach the scene
- 5600K — 15,000 lumens: daylight-balanced white for nearby reef detail, divers and subjects you want to illuminate with a conventional white-light setup. CRI 90 supports colour rendering; set camera white balance for the scene.
- 8000K — 25,000 lumens: the maximum-output setting. Choose it when output is your priority for wide-angle reef, wreck and larger-subject work, while accounting for its cooler white tone.
- 16,000K marine ambient — 15,000 lumens: blue-shifted illumination for working with ambient blue water. It can help reduce the colour contrast between your added light and the surroundings, depending on the water and your camera settings.
Colour temperature is a tool, not an automatic correction. Water colour, depth, visibility, exposure and white balance all influence the image. The advantage is having a choice at capture rather than committing to one fixed output colour.
Wide coverage with output to work with
A 120° beam on land and underwater provides broad coverage for wide-angle compositions. The 8000K mode supplies the light’s maximum rated output; the 5600K and 16,000K modes are rated at 15,000 lumens with CRI 90.
Use that output alongside good technique: get close to your subject, position the lights to limit backscatter, and adjust exposure as the scene changes. Brightness gives you options, but it cannot remove the effects of water between the light, subject and camera.
Control from the light—or your camera tray
A button-and-dial interface with an LCD screen puts settings and battery information where you can check them. Choose from 11 power levels across 0–100%, with White, Burst and SOS modes.
For a dual-light rig, the optional RC02 remote lets you adjust compatible lights from your tray rather than reaching along the arms. It is a useful addition when you want to keep your hands close to the housing while setting up a shot.
Match runtime to the way you shoot
The rechargeable pack contains eight 21700 cells. Rated runtimes are:
- Approximately 60 minutes at 15,000 lumens in 5600K or 16,000K mode.
- Approximately 30 minutes at 25,000 lumens in 8000K mode.
Choose the output you need rather than running at maximum for every scene. Actual runtime varies with operating conditions. USB-C PD charging takes approximately 4.5 hours from empty; a compatible spare pack lets you swap batteries between dives rather than wait for a recharge.
Which Spectrum suits your rig?
Choose the Spectrum 25000 for its higher maximum output. At 1,410 g including the battery, it suits shooters who want the capabilities of a larger video light.
Prefer less size and weight? The Spectrum 18000 offers up to 18,000 lumens, three colour temperatures and stepless dimming in a smaller, 990 g package. It is the compact alternative for divers who do not want the heft of a 20–25K-class light. Both Spectrum models support the optional RC02 remote control.

Battery and air travel
The 144 Wh battery falls within the over-100–160 Wh category that can be carried with airline approval. Confirm requirements with every operating carrier before travel. Spare or removed packs must travel in cabin baggage with terminals protected; the standard allowance in this category is up to two spares with airline approval. Protect batteries from damage and the light from accidental activation.
