I've taken a bunch of pictures (attached). While doing that I discovered 3 things:
1. Although it's using the original fluorescent bulb power supply, the bulb itself is a newer LED one
2. That doesn't prevent it humming
3. The length of the cavity for the light is 12", and there's enough depth...
I’ve encountered advertisements for the illuminated Macintosh Picasso Dealer signs with a LED light instead of the original fluorescent. I’m looking for information on how to do this replacement for my own sign. I‘ve attached an image of a sign (though it’s not my one.)
Any help appreciated...
