anyone seen hqi 250w de test results?

[big 5]

i thought a report was coming out soon on all the double ended bulbs?
i hear people saying the 150 hqi 10k hit harder(par) than a 175 and = to a 250
250 hqi de = to a 400
where is the proof?

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.
