Just got a new 1000 HPS to replace an older one. I hooked it up, turned it on and waited a few hours, for some reason this new bulb seems dimmer than the old one that's already been used for a few monthes. Do I have a dud or does it require kind of a breaking in period before it really shines. The newer bulb is from 1000bulbs.com, the older one is a sylvania lumalux, both are rated 130000 initial lumens.
