My brother has some 24 watt10,000 k super bright daylight T5 HO fixtures I don't know what brand they are, but they are 24 inches long, my question is are they too much for vivarium use?

Thank's Matt

That type of light fixture should be fine, just check as with all other lights that it doesn't get too hot in the tank. 10,000K is used more for reefs and aquariums- it is a very crisp white with a hint of blueish. It will be fine for the plants and frogs, but plants will grow much better typically with 5500-6700K as MeiKVR6 noted because that is closer to what sunlight is.

On the flip side, 10000K is usually more pleasing to the eye... if it's a two bulb fixture, I'd switch one to 6700K and keep one @ 10000K. A ton of the freshwater planted tank guys do it that way, because it looks great and still keeps the plants tip-top.

Thank's everyone for the replies. My brother actually has all kinds of lighting that hes no longer using and hes willing to give me whatever I can use.


Thank's again Matt

There won't be any noticeable difference (either visually or growth-wise) in your plants if you use the 10k bulbs that are already in there. While 6500k is the spectrum of tropical sunlight at mid-day, 10k is just as usable for plants and both are used commonly by freshwater planted tank enthusiasts. No reason to spend more money on new bulbs until you need to.
