Leds are used extensively in the sign business these days. Dimmers, power supplies etc. are available from an electric sign supplier . Allanson and Sylvania make products with the ability to change colors but it can get expen$ive.
These are the large outdoor road signs. I have used that same buzz in an AM radio
to determine which neon tube bordering the interior of a restaurant was starting to go bad, even though all of the tubes looked good.
U.S.
Outdoor, not near any type of kitchen exhaust
Lowest bidder, yeah probably, but the same name brand lamps and ballasts are used throughout the industry.
Does anyone know anything about: 1. Harmonic distortion
2. transients
Thanks!
Well, one problem restaurant is a national chain, signs manufactured by the same company,
lamps and ballasts are the same and operating hours are consistent.
Hi all-
Can anyone offer any insight into a problem I've noticed for years but don't know how to solve?
I'm a self taught neon tube bender. I am not an electrician or electrical engineer.
Through the years, I've noticed neon tube, fluorescent lamp, transformer and ballast failure more often...
