Godox WT40D underwater LED tube light

The Godox WT40D is a waterproof LED tube light designed for divers and for underwater photography and videography. The IP68-rated housing can withstand depths of up to 40 metres, and the daylight-coloured light reproduces colours accurately even above the surface.

Automatically boosts power underwater

Underwater, the light automatically switches to high-power mode, increasing the output to up to 54 watts. The fluorescent buttons stand out in dimly lit water, so you can switch the light on and off, change the mode and colour, and make other adjustments without any fumbling. The battery level indicator shows the remaining runtime, making it easier to plan your dives and photo sessions.

Settings and lighting effects on your mobile phone

With the Godox Light app, you can adjust the brightness, colour temperature and lighting effects from your smartphone via a Bluetooth connection whilst standing above the surface. There are 13 pre-set lighting effects, so you can quickly create a variety of moods and scenes.

Main features

• The waterproof IP68 design allows it to be used at depths of up to 40 metres.
• High CRI and TLCI values (≥96) produce natural colours in the image.
• The 1/4″ thread at either end is suitable for attaching a ball joint and other accessories, leaving your hands free for filming.
• The included ¼”–1″ ball joint connects the light directly to underwater mounting systems.
• With the light holders available as optional extras, you can create more extensive lighting set-ups.
• The USB-C charging port and a charging time of approximately 2 hours and 20 minutes get the light back up and running in no time.
