I can't think of a single place the designer or manufacturer went wrong except the instruction sheet. The pictures of how the bits fit together are too small and grainy. But I managed to figure it out so "anyone" should be able to do it (it would help if you've played with and Erector "construction set"). Just be sure to leave some "play" in the hardware until the reflector is fully assembled, then tighten the screws; working out from bracket on the tube, tightening one corner at a time. Also; make sure to remove the protective films from both sides of the reflector pieces before assembly (it's a real pain to remove it afterward and I'm sure the fumes if it melts won't be pretty). One last tip; powder-free latex (or nitrile gloves if you're allergic) can be used to avoid corrosion caused by sweat and/or skin oils (and they work great for installing/changing bulbs, too). The reflector is amazingly sturdy once assembled (and is easy to disassemble for compact storage). And did I mention that it's huge? Well; the 31" tube is quite large enough to hold two sockets and bulbs (as I'm pretty sure H.W. has done in the "dual lamp" ballast packages) and it would be (almost) less expensive to mount a 600W HPS and 400W MH in the tube than it would be to buy a single "dual arc" bulb. This is what I plan to do if I can manage to buy/build the parts... And it'll be a "perfect" light for flowering plants in a fairly large area!

If you want the footprint of the magnum in a cheaper and in my opinion better designed reflector, this may be for you. My grow room temps are down 3 degrees once i got this reflector and thats part of why im happy, my last reflector didnt move air as effective as this, so i think its a cooler reflector. Two harvests and counting so far, ive purchase 4 of these total now and i cant believe how great they are.
