cMidd Posted February 23, 2011 Posted February 23, 2011 Anyone have experience with these "spotlights?" I have 2 and a panorama actinic about 12" from the water...thinking 18-20" will be better? Getting darkspots in the middle. Opinions?? Quote
DaJMasta Posted February 23, 2011 Posted February 23, 2011 I've got a pair lighting my 24g nano cube right now (will be three in about a week). With 40 degree optics I get pretty good coverage an no noticable spotlighting (blended beams in the center) when they're approximately 1" apart and 20"over the tank. With 60 degree optics you could probably do with 12", but with a smaller beam size from tighter optics they will need to be higher up to spotlight less. The nice thing is that thanks to the optics they will have better penetration at depth, so you should still be getting a good amount of light. You will not be able to stop the spotlighting if the bulbs are too far apart, especially if they have optics. Quote
cMidd Posted February 23, 2011 Author Posted February 23, 2011 There's a panorama strip between them in thinking of removing to another tank Quote
