I am finalizing my clam tank, and need to decide on lighting. The tank size is 36x18x12, and the pendant will be hung about 12" about the water. The total diffrerence in cost will be about $80. The other issue is heat, I will have this plumbed to the 55g sump of my 125 G display which has 3x 250 mh and 4x55 pc. It gets pretty hot but I can control with fans. Thoughts?
 
You could split the difference with a 250HQI. The issue you have is more covering the 36" spread than light intensity.
 
I aree with peabody concern more on light spread. I am not too much of a fan of HQI's because of their shorter life span and the need for a glass shield. I have a 250 watt 10K XM over my 40 breeder at 12 inches off the water, and my Crocea and Maxima are doing wonderfully.
