Metal Halide bulb

[behaguef]

Hi there:

I am about to replace my stock bulb in my Aquamedic. It's a 150W 20K AB. What do you recommend? I heard a lot about Phoenix and Reeflux. Any thoughts?

Thanks,

Here's the Performance Results for all the 150w MH bulbs Sanjay tested. I don't see any results for the AB 20K for a comaprison tho. The Phoenix are listed and so are CoralVue (Reeflux).
PPFD is a measure of PAR, so that's an important thing to look at.
CCT is the actual Kelvin color temp of the bulb.
