Thats the light I use on my 8gallon ex-nano, currently mantis tank. Purchased from Golds for $35-40... can't remember.
They work pretty well, only complaint is that it gets pretty hot, so its best to have legs so its up a bit from the water, so it doesn't mess with the tank temperature.
I would have used a desk lamp and put a different bulb in it, except I was short on room, and wanted something just on the top.
