Coral Fluorescence under UV orphek ML7
Here’s the answer to the dimming question…
The PR-25 is a PAR38 formfactor bulb (screws into a normal light socket) and is a 70-150w halide pendant replacement. The PR-25 LED pendant produces a similar amount of PUR (photosynthetically useable radiation) as does a 150w metal halide bulb, with excellent spread from 60 degree honeycomb optics. Containing 12 diodes running at 2 watts each and available in various color combinations, the PR-25 is an excellent, cost effective and efficient choice for nano and mid-sized aquariums. The PUR ratio is so high than ~50-60 PAR under the PR-25 is equal to ~150 PAR under a 14k halide bulb. Even better, the PR-25 is dimmable with a common household dimmer! This is truly a 150w halide pendant replacement for less initial and operating costs – not a spotlight! Each light has approximately the same coverage as a 150w halide pendant, as well.
