Hi All
I just replace my two old 150w 10K Coralife HQI Double Ended Metal Halide Bulbs with 150w 15K XM HQI Double Ended Metal Halide Bulbs and they are not even half as bright!
I read online that I need about 100 hours for it to get to its true color. Does this include the brightest as well? Or is it because they are 15k as opposed to the old 10k. I knew I was going to lose some brightest but heck my 65w PCs in my sump look brighter!
If so, I'm going to get the 150w 10K Ushio HQI AQ Double Ended Metal Halide Bulbs instead.
Any info will greatly be appreciated!!!!!!!
