I use the compacts as spotlights on my orchids in two other rooms.

The left side of the light fixture

And the right side

I have two bulbs on the left because that is the 'high' light area of my tank, and the right is the low light area. I forgot to take a close-up of the way it's hooked up to the actual bulb, sorry! The smaller bulb on the right side of the left side of the fixture is a Daylight bulb, the one from HD. The others are a highter wattage (150) that my husband has to buy specially at an electrical wholesaler. They are also Daylight spectrum, but the one from HD is more white/blue and less yellow. So eventually I may just add a couple more sockets (translation: get the DH to add more) and use only the HD bulbs. They are only 90 W. Hence the need for more if I switch over.

The entire fixture is four feet long. The white reflector dealie my husband bought somewhere, probably the wholesaler. It was already formed and painted white, on the theory that white reflectors actually do a better job, because they reflect all colours of light, whereas those silvery ones are more grey and therefore scew the spectrum slightly. don't know if that's true or not, and don't really care, since my plants are doing just fine. =)

The black sockets came with the cords and plugs (which, of course, you can't see in the pic) attached, and were bought at IKEA for about $4-6 each. One part of the black socket unscrews from the other, and my DH made some kind of metal holder that screws into the reflector and hangs down and has a hole cut in it for the socket. So you stick the socket through the hole and then screw the other piece back on, which attaches it nicely, and then screw your light bulb in, capice? (sp?)

Any further questions, just ask (on the forum, please. I dislike people I don't know emailing me privately).

Incidently, polished aluminium is one of the best materials to make a light reflector out of - it reflects most of the visible range, but absorbs the much of the heat range. This allows you to conduct the heat away from your lights, and thus plants, more easily.

You're not going to find polished aluminum. You will however, be able to find aluminum sheeting and then put a polish on it. It's fairly easy, not terribly complicated and anyone can do it with a $10-20 investment in supplies.

Not sure where to get the chemicals yet, I might have a chance to go to the hardware shop today and look around. The effect is pretty amazing - look at the car at the end.

400 grit wet sand
600 grit wet sand
Aluminim polish either by hand or, better yet, a polisher.

As long as you're starting with a relatively smootha nd inscratched piece of aluminum, you could probably even eliminate the 400 grit step.

To wet sand- spray down piece to be sanded with plain old water, use wet/dry type sandpaper, and sand in nice little circles along the surface of it. Keep it wet, keep it clean.

For the buffing/polishing stage, I usually use a product called Blue Magic. It is a silicone-based aluminum(actually all-purpose) polish. Works wonders. I use the stuff on everything from wheels to auto parts, my wedding ring, you name it, it'll do it.

I would stay away from high-grit polishes like brasso, but in a pinch, you could probably use toothpaste. Yep, plain old toothpaste. Mother's also sells aluminum polish-find it at your local auto parts stores.

NOTE: When using polishes on aluminum, it is normal to come away with a lot of black residue. THat is the aluminum being removed from the sheet. When you're done and need to see your work, pull out a bottle of windex and a clean cloth to remove it all. THen you can admire your work :-]

For aluminum with more than just a few minor scratches, you may need to bust out the rouge and other compounds, but that's probably a little more complicated than is needed for our purposes.

Oh, and for the polisher, Harbor freight sells dirt cheap power tools and they have a few different models of polishers. www.harborfreight.com

If I wasn't clear about any of this, let me know and I'll try to walk you through it. I've done more than my fair share of metal polishing.
