wired up those lights and wow ... now I know that the lumens are nearly double when a bulb is first used as opposed to after 100 hours operation, but these lights were bright even in a sun filled room!
and hot is an understatement! ... even with an oven mitt, the bulbs were warm to the touch ... without, it's like touching a 100 watt halogen flood after it's been going for a while
I just layed them on the glass canopy of my 29 gall, and it looked as if the sun were shining in there ... everything looked a lot better, colors were brighter and clearer... these bulbs made the GE SPX50 look pale and yellow in comparison
so, after I recover from paying my Q2 taxes, I'll be buying a 2x 55 watt kit for the 29 gal
.. the 4x 24" spx 50's are going to the trash where they belong ... I'm sold on PC
