Godox WT40R underwater LED tube light

Godox WT40R underwater LED tube light

The Godox WT40R is a waterproof LED tube light designed for divers and underwater photography, and it also works on dry land. Its IP68 rating means it can withstand depths of up to 40 metres, and both colour temperature and colour tones can be adjusted over a wide range. Take a look at our other products too for monovole and Fresnel lenses.

More power underwater

Underwater, the light automatically switches to high-power mode, increasing the power output to 55 watts. On dry land, the power output is a maximum of 15 W. The fluorescent buttons stand out in the dark, so you can switch the light on and change the mode and colour even at depth.

Thousands of shades

The CCT, HSI, RGBW and GEL modes cover both natural white light and vibrant colours. With 13 lighting effects in FX mode, you can create atmospheric shooting scenarios, whilst high CRI and TLCI values ensure accurate colour reproduction.

App-based control and flexible mounting

With the Godox Light app, you can adjust the brightness, colour temperature and effects from your smartphone from a distance of around 25 metres at the water’s surface. Both ends of the light feature a 1/4″ thread, to which you can attach the included ball joint or other accessories. Light clamps, available as optional extras, expand the mounting options.
