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.
