Apply this Sea Dragon Red Fire Filter from SeaLife to their Sea Dragon Photo/Video dive lights to create a warming effect that won't alarm underwater critters. This accessory changes the wavelength of the bright white light so that it shines in red. The result is dimmer, softer illumination that invites your subjects to stay visible, instead of scaring them into hiding in dark shadows and crevices. The Red Fire Filter is designed for use with all Sea Dragon lights that output 1200 lumens or more. It can be attached with ease above or below the surface and has a small lanyard that helps ensure it doesn't get lost.
