250w DE 10k bulb question
Deciding on a new bulb, i have the 10k Ushio now and looking for better output. Am i reading the numbers right...that the XM with a ppfd of 95 and Reeflux with a ppfd of 86.1(all used with icecap ballast) would be a better choice than my Ushio with a ppfd of 65? These numbers came from Sanjay.

I am surprised how low the Ushio is in comparison.
Being that u suggested the XM, i take it the higher the number the better. Also, i am surprised the SE version of the XM is 115 and the DE was only 95.
