Query: Really????

I read the reviews of others and was still willing to take a chance on the product since it was cheaper than Petco. I did not get one hour of use from this bulb! I installed it into the lamp and plugged it in and the light immediately came on - I flipped the switch into the off position and put the final touches on my tank - all of 5-7 minutes. I went to turn the lamp on again and it didn't work! I switched out the bulb to determine if the lamp had problems or if it was the bulb. It was the bulb. Most complained of the short bulb life - but this was ridiculous!!!
