DIY Lighting

So what parts do you need for DIY Metal halide lighting
I know you need a Ballast, reflector, and bulb... what else?
Also DIY VHO lighting?

For my MH lighting - I have
Ballast. DIY might mean attaching plug [wall] and cord to socket.
Socket. Might need to attach, pretty simple.
Reflector - IMO, get a good one. Makes a huge difference, Sanjay Joshi has some great articles on which are good/why in the http://www.advancedaquarist.com archives.

And the bulb [of course]. Check out http://www.cnidarianreef.com for some great information/photos [under 250w lighting study] on MH's, which bulb gives what PAR + pics of all the combinations.

For my VHO - I just needed the ballast, endcaps/wiring-harness, and bulbs. Internal reflector [but attached to my MH reflector as it has places for VHO]. A bit simpler, but not radically so.

what about this? is this everything I need to put my VHO's together? I was thinking of getting mainly VHO's and then MH for the center 24" so I can put an anemone, and some SPS! Tell me what you think!

I was thinking these VHO's (the 60" 420 Watt Ice Cap 660) and then a 175 watt MH added to the center for some SPS and maybe an anemone?

I'd suggest 72" bulbs, as otherwise there will be greater shadowing ... and I almost think that just 1 MH would be really `center spotlight, shadowed corners' esp with 60" bulbs - which running 1 MH on my 36" tank sure felt like [with pc's, only 2' long]

Reflector would be a big deal in this situation IMO to help avoid this [www.advancedaquarist.com archives have great reflector articles by Sanjay Joshi ... might need a thread here so we can put all our minds together to decode it ;) ... but that's fun too].

I dunno, I'd go with at least two. At least then there's more covered in high light. But check with 6' tank folks - as they know best.

Personally, when I upgraded my reflector to a PFO parallel [best choice for 2 MH on a 36" tank with actinic supplimentation, IMO] - it was stunning what having the corners + every part of the tank did for making it aesthetically pleasing. I'd do your best to light it end to end somewhat evenly - or so I like the look of. All opinion, take as you may :)

Thanks for all the help Mark, I thought of the whole light and shaddow aspect and maybe a 48 inch would be better with 2 MH on the edges. Right now I'm just trying to get the darn thing started up so I can get my fish in there (since they are crammed in a 55 gallon and a 20 gallon right now) I will read that thread in a while as I have 3 exams this week, ehhh, I'm burnt out of learning already hahah...
