One of the HF undercabinet lights failed.

Postby MetalHalideHater » Thu Jan 26, 2012 6:49 pm

It had been flickering for a while, then just died. Lamps was incredibly blackened, but started on a 40w SS ballast fine. On opening up the fitting, one of the three legged transistor things had burning under neat, which I presume caused the problem. Anyhow, it'll probably be replaced by SS, if any SS fitting fits in the space. What's the thinnest two foot SS fitting?

Your best bet would be a Fitzgerald Slimline Lightpack or a Thorn Arrowslim, the Fitzy being the better of the two! The narrowest ballast and starter switch. Upon switch-on, the starter closes and preheats the tube's cathode filaments. Upon opening, the magnetic field within the ballast collapses, causing a voltage pulse which strikes the tube. This is often repeated twice or more, causing the distinctive blinking at startup.">switchstart 2 footer, if you can find one would be a Linolite Hi-Line. These were also good little fittings but not sure if they're still made! eBay is the best bet for any of these!
I LOVE LAMP!

You should have changed the tube first sign of flickering and prevented a ruined ballast

Electronic ballast should have auto shut down. It is obviously reached EOL. MLP13 would be a cool replacment MHH
