    Lightbulb Let there be...

    Just a quick bit of knocking some scraps together to put up a new LED outside light. Opted to add a brace, since I don't have anything real strong to attach to. The light output is good on these but the pattern is more directional than the light it was replacing. So raising it up should help to get back more coverage. Amazing how much light these put out with only 350 mA. Mix n match of what was laying around, .065" wall tubing and some flat bar. Set the arm up at 40° and used TIG. Welded on a 1/2" NPS locknut on the side, so I could attach conduit right to the arm and run the wires inside. Now just waiting for darkness.

    Where did you get these and are they economical to replace?

    Is that hot rolled? Looks like you removed all the mill scale... for paint adhesion?

    What paint adhesion?
    You can see I chipped off some paint just installing it. Yes it was hot rolled, but I only ground off the scale where I was welding. I usually find paint sticks fine to mill scale, but this was painted in the middle of the night with whatever crap paint I could find. It started as one color than went through two more before I found enough white left in a rattle can to finish. I think I mentioned in another thread how much I dislike painting.

    Honeywell fixture, $60 at Sam's Club. Works good, I'll see how it holds up. So far mercury vapor and metal halide work great and last a long time, but suck down the power. The fluorescent replacements have been hit n' miss (mostly miss) in the longevity department.

    I hate painting too. I TRY to leave that to the customer. But seems more often than not someone is always bringing me something to paint. I am no painter, but back in August a lady brought me an antique iron bed that she wanted repainted to the original brownish reddish color. I made the mistake of letting her bring me some Sherwin Williams crappy paint. Run city. My sprayer handled it fine, but runs popped up quickly even though I had thoroughly prepped the old paint with a really good and tedious sanding job and a complete wipedown with acetone then a tack cloth. It slicked up nice, but would not dry for days in 80+ degree heat. It was still soft after 2 weeks. I had to wait till it got try enough to sand down again. Second time it was much better and the one or two runs I had did not really matter where they were located. For simple stuff, I use rustoleum, usually hammered paint. Nothing beats it for ease of use, coverage and quick dry time, especially if I am not using a can. It dries even faster in a can. And it is DTM. No primer needed. Beautiful gloss finish but with the hammered "industrial" look. Some people can't tell it from powder coating.

    I tried some silver hammered paint. I love that stuff, too. But the can was too old or something and I could not get it to spray more than a few seconds before clogging the tip. Then would have to clean the tip out with acetone only to have it clog again and again. I gave up and found a can of white that still had something in it.
