Fixtures & Bulbs...opinions/experience?
 

Does anyone have any opinion/experience with this bulb?

What about this fixture?

There are actually four bulbs in that link. AB generally makes good stuff (I run their 175 SE 13Ks), but all you need to know about any MH bulb is here:

Aquamedic also makes good stuff and quite reasonably priced for a German brand. I think of them as VW to Geissemann's Audi. :)

Yo can see the spectral analysis of AB 250 Watt 10000K HQI at the link.
