The studies of the Double-Ended bvulbs were published in AA:
250w - http://www.advancedaquarist.com/issu...4/feature1.htm 150w - http://www.advancedaquarist.com/issu...2/feature2.htm The results show basically what you have described. The 150w is a better choice because the spectral distributions compared to a 175w are very similar and it consumes less power. Same for the 250w DE, a big bang for the overall buck.  Scott Z. |
