I have the same lights that came with my 55 gallon package. I liked that they were LED's but had read that some didn't like them very much. I have to say thou, for a 55 gallon tank they are perfect, you get the shimmering effect, they reach the bottom of the tank and fill it front to back very well. Might be different on a deeper / wider tank, but for a 55 gallon setup two of these lights are more than adequate. I would suggest them to someone else for sure. You can buy these hood/light combos from many retailers for many different tank sizes. I was tempted to buy a hood/light for my 29, but since it will be the angels home and I'll be planting that tank I'm going to go another route.
