I am debating on whether or not to switch to the G series SOLARIS. The fixture puts out the equivalent of a 250w 20K metal halide for every 1.5 feet. I would be getting a 36" fixture so it would be equivalent to 375w. I currently am running 2-150w metal halides and 4-40w T5's @460w total. However, solaris claims that the LED's put out a higher PAR than the MH because the light is more direct. Will I have trouble keeping SPS with this light? I have a 70 gallon TEC tank. 36"L x 18"W x 26"H. I really like the idea of no bulb replacements and lower electric bills. I can pick up the G series for this tank for @ 1100.00 I am hoping to get $400-$450 for my current light so the upgrade would only cost me $650-$700 (about 3yrs bulb changes). Plus the savings on my electric bill. Please help me decide lol
