Query: Absolute garbage--will not last more than two weeks...

I replaced the "real" 5 watts bulbs after nearly two years with this apparent knock off. I bought two. Within a week in a half the first bulb just blew when I turned on the aquarium light. I replaced it with the spare and two weeks later "pow" same crap. Spare yourself some trouble and money and do not but this light.
