Review on Zoo Med Tropic 5500K Daylight Fish & Aquatic Pets by Allison Sanchez

I bought two of these lights. Upon arrival, I unpacked one and popped it in the hood. At first it glowed very dimly and then burned out within the first hour of use. The second bulb I put in flashed at full brightness when first turned on, then settled to the same dim light as the first. It burns for 2 hours and hasn't burned out yet, but very weak. Not very happy with this purchase considering they are $15 each.
