Ikelite Red Filter M27 for Gamma Waterproof Flashlight

Illuminate and observe underwater sea life without scaring it off, thanks to Ikelite's Red Filter M27 for their Gamma Waterproof Flashlight and other lights with M27 (27mm) thread diameters. The filter screws onto the front of the light and gives the beam a red hue, which allows you to maintain visibility in darkness without throwing bright, harsh light on your subjects. Additionally, the accessory can be removed and replaced underwater and is supplied with a lanyard for safekeeping.
