Here I have my Landmark 250W HPS installed running with a Philips 250W ALTO Retro-Halide lamp,the Landmark fixture is a Canadian made equivalent to the AEL 313 Powerpad.
Very nice! Any plans to install the M-400A2 outside when you get it? 320W PSMH is quite a bit of power but you could use a part-night PC and the way I wired the plugs, you can bypass the powr/module to get straight 120V to the socket so you could run a giant CFL if your that type of person.
Thanks! I think I will probably keep the M-400A2 inside,yeah 320W would be nice and bright,the Philips 250W Retro Halide is actually really bright and lights everything up,nah no giant CFL's for this guy,HID all the way!
