14k/20k MH Bulbs With Highest Par?

[rastaangel]

So up until now I have been running 10k bulbs in my 2x250w MH hood. It has resulted in amazing growth but duller colors then I would like...
What 14k or 20k bulbs have the highest PAR out put? I know I wont find one as high as my 10k but as high as possible...

What ballast are you using? Electronic (what brand)? M80? M58?
Sometime the ballast will affect the output of bulbs. For the latter 2 ballast types, they can dictate what bulbs you can run.

Check out Sanjay Joshi's site. This guy is anal about his lighting. I've had the best result with the Phoenix 14K.

Yes phoenix 14k is hands down the best mh bulb for color without loss of growth

10k will give you lots of growth,14k will give you a nice ballance of color + growth,20k will slow your growth to a crall but your colors should be way way more intense.
This is what i've noticed in my sps dominante tank.
