I bought two of these for my 100 gallon Cichlid tank, and the colors really pop! It is a very natural, bright light.

This is a great bulb that adds light to my fish tank. My fish really love this light. Only downer it only lasted me 8 months. I turned it on in morning and turned off at night. It might be all that it can handle being On. Just thought it'd last at least a year.

I needed some new lights for my 55gallon tank. I have more than 10plants in my tank so i needed a great light to make them as green as possible. I haven't really seen a difference with my plants yet but its only been one week. I have noticed that the plants have more of a glow to them. Its better than the other lights i had.

Wow what a bright bulb. It makes everything bling bling in your tank. Make sure your tank is clean because you cannot hide anything with this bulb. It makes our 20gal tank in a waiting area really stand out. People comment how nice it looks all the time.

This light is great for a planted tank but not good with a tank wit few plants its just to bright for cichlids they always seem to hide but they got used to it but still my 2 crayfish wont come out if lights on!! so its ok to me in my opinion!!

Really bright light. Looks great and would not go back to the old ones. Tryed other zoo med lights and this is the best so far. go with the 10K

I bought this bulb for my freshwater planted aquarium, and my plants showed new growth very quickly. The bulb has a bit of green tint to it, which makes the tank look even more green. It helps to have the right equipment when growing plants, and I think I've found it. You don't need to spend a ton of money to have some nice greenery in your tank.

I use this and my plants keep dying. I don't think that it works all that well.
