Waterproof 15-inch Dive Tube Light

The Godox WT40D is a 15-inch daylight tube light rated IP68 for depths up to 40 metres. It delivers 54 watts of output and automatically switches to high-light mode when submerged. Bluetooth app control is available only above water. Two mounting options include a 1/4-inch screw or a 1/4-inch to 1-inch ball joint.

Underwater Photographers Needing Reliable

This light suits divers and underwater photographers who require consistent daylight colour at depth. It is not intended for buyers who need surface-only studio lighting or video lights without waterproofing. Users who require continuous Bluetooth control while submerged should consider other solutions.

IP68 Rating Allows Operation at 40 Metres Depth

The IP68 certification confirms the housing withstands pressure at 40 metres, which is the decisive factor for deep-water use. Without this rating the light would be limited to shallow or surface work. Fast charging via USB Type-C and battery level indication support extended dive sessions. Thirteen built-in effects modes add creative flexibility underwater.
