Review on 🎨 Tetra 26657 ColorFusion: Experience Mesmerizing Color-Changing with Universal LED Light by Jess White

I have 2 of these and love them. Of course they are not the "ideal” main light source for every tank. This is a very good accent light. Press the button to freeze it in any color, hold the button for a few (4-5) seconds to turn it off. I bought it here for about $5 cheaper than the first one I bought at Walmart. Fits easily in my 20 gallon rimless tank, but if you have a rimless you'll need to get a little creative to get it attached properly (I'm STILL working on the correct solution for my 3 gallon rimless tank). Sealed well so you don't have to worry if you drop it in the tank. In fact, my original, which I had for about a year and a half, spent most of its time slightly submerged due to all the "not for rimless tanks". " and that I haven't found a REALLY good alternative to attach it. :-/ Also, it didn't fit the thicker rim of my 75 gallon. Wouldn't tear because the rim is too thick, but that could be because of that that my tank is VERY old, maybe the newer ones have thinner rims, idk, but overall I love this light a lot.
