Agromax huh, okay... I'll take a crack at them.... VERTICALLY.
I've used em like that too, put a 600w Agromax hanging vertically on a lightmover to cover the outer overgrown portion of a bio-bucket setup. It worked great! One thing, I'd recommend getting the Gavita Dew-Guard, it's worth it just for the adjustability of the mogul socket alone, full 360 degree adjustability, which helps to position the bulb just right. I think I paid like 70 bucks for em when I bought them a few years ago...You could probably DIY something if you wanted, but if you have the dough they're worth it.
