No I got my 400 watt at a hydroponics store in burnaby, I keep orchids and I used the 400 for them. I just adapted the system to a horizontal bulb and got the bulb from J &L.

I believe that for a DE bulb you'll need an HQI ballast which the M81 appears to be if I'm not mistaken. Steve or Tony would be the ones to ask.

Hm,...how much did your 400W setup cost? Was the bulb the most expensive component?

No the bulb and the ballast were about the same price, if I had known about Albrite I would have gotten my ballast through them. All total I spent about $300 on my 400 watt unit including the bulb and reflector.

Seems like a good price for a 400W setup :biggrin:
