I have some issues with these strips.
1. They are not waterproof or water resistant like the others we have been discussing in this thread. This means you have to place them so they shine through glass or in an area that they DON'T GET WET. . Spray will eventually short out lights unless you have them sealed or away from the spray. I learned this the hard way.
2. They are 1 Watt LED's. My experience is that 2 or 3 Watt LED's work better. The write up for this one says that the seller has had success using them for algae scrubbers.
They may work fine.
Algae Scrubbers are a fun part of reefkeeping.. You get to play with saltwater and electricity at the same time.
