XM vs. Hamilton

lechee12 · 04/03/2007, 09:23 PM

i was looking at sanjay's lighting website trying ot decide what bulb to use. Accordin to it hamilton 14k's have a PPFD 53 while xm20k's got a PPFD 73....does that mean the xm20k's have better growth then the hammy 14k's??? can that be right, i've seen both in person and the hammy 14k are much brighter

thanks

lol the color form the 20k's are great....but i want bulbs that will give decent growth and color without the need for supps. So my question is which bulb is better?

I will have to go with the XM's, I have ran both on my new 180, XM look better and have better PAR

thanks guys...now do you think if i ran 2 x 250watt xm20k's on lumenarc mini's over a AGA 65 gal tank without supps it will be enough light for my sps?
