The Science of Underwater Fluorescence

The Art of Underwater Fluorescence

Compact Fluoro Spotlight

It’s easy to see underwater Fluorescence with the new Sea Dragon Mini Fluoro. The Sea Dragon Mini Fluoro Underwater Fluoro Light’s royal blue LED emits a blue light combined with a finely tuned and proprietary dichroic filter that pinpoints the exact light wavelength to get the highest energy response from the underwater plant or creature for an amazing underwater light show.

 The light functions are easy, with simple one handed operation and three Fluoro power levels.  And to eliminate any excess blue light, a yellow barrier mask filter is included. Runs on two CR123 or a single rechargable 18650 Li battery (batteries not included).
