This season my Q-beam hand held crapped out. So, this past weekend I took it apart for failure analysis. It's usually the switch, but this time it was actually the bulb. I can't understand why a bulb would quit after 35 years of abuse (manufactured in November of 1983), a "blue eyed" Q-beam bulb.

A-HA, time to replace this with the old GE4509 landing light.
The replacement was a smaller diameter light than the Q-beam, so I had to figure out how to increase the diameter. Decided that the simplest thing would be to get some 7/16 fuel line, cut it lengthwise and wrap it around the perimeter. It's going to get hot, so I decided to seal it up with high temp gasket sealer. Sealed the hose around the light with the gasket sealer, then had plenty of sealer leftover and since you can't just cap it and use it later, I used it to seal the new assembly to the light housing. Works just fine, and if the this light blows, I can just take a razor blade and cut it out. 99% waterproof too (the switch and screw holes aren't waterproof)
The only tricky part was that the Q-beam bulb was flat and the new bulb is convex, therefore extending beyond the frame of the housing if you just plop it in there. Had to set it back 1/4 inch to protect the bulb. Voila!
I wish I had more time for stuff like this. Completed McGyver set up.
