Comments: Well. Received the LED Stunner and per the sites these are suppose to increase the out put by 3x the regular output. No not really. I couldn't see any difference at all. Maybe it was just me.

Comments: The reflectors definitely make a visible difference in increased output, though not "double." I would recommend them to get the best performance from the stunner LED strips.

Comments: I placed these on my stunner strips and the difference was amazing. Literally double the light in the tank and more apparent shimmer. I use only stunner strips to light my 90 gallon FOWLR tank and the fish are happier than when I had PCs. I only put 2 of the stunner strips with the polished reflectors and the light level is very acceptable. Not to mention, I am happier with the difference in my light bill. The tank is 48"-18"-24".

Comments: This is a must for the stunner.
