Many sea creatures get frightened by bright lights. They stay in dark shadows and crevices or only venture out in darkness. The Sea Dragon Red Filter uses a special formulated wavelength that has been tested to not frighten those elusive light-avoiding sea creatures.
The filter easily snaps on/off underwater and works with Sea Dragon Photo/Video/Dive Lights with 1200 or more lumens.
NOTE: The Red Fire Filter will disable the flash detect and auto brightness features on Sea Dragon 2000 and Sea Dragon 2300 Auto underwater lights. The Red Fire Filter is NOT a imaging filter, it’s designed to aid in underwater navigation in darkness so to keep the eyes aware and dilated, this feature also prevents frightening nocturnal sea creatures. To use the Sea Dragon light for imaging, the filter should be removed.
