I purchased 2 130watt CustomSeaLife lamps with Smartlites. Smartlites are one 8750k and one super actinic bulb in one. I know they make a 5500k and a 6700k set of lamps in my 65watt style. What are the advantages between the two lamps and please only reply if you are currently using these types of bulbs on your systems. General info doesn't help as much as personal experience. I already know what the different kelvins mean and how they are supposed to effect plants and algea. I need to know who has tried the different lamps and what effects they experienced before I choose my next set of lamps.
