Inside a vintage disco light.
Added 2019-02-18 23:05:35 +0000 UTCThis "single Derby" light is one of the simplest disco lights of all. It just projects a flat line of coloured light.

If it is sequenced to the music it is just turned on and off in amongst a group of lights by a separate power controller.
Efficiency of lights like these is terrible because they only utilise a tiny percentage of the light output from their lamp.

I have a basement full of disco. I'll need a huge bench to fix it all. Some still works, but why ?
2019-03-20 03:55:47 +0000 UTCI did some urbex quite a few times at an old mental hospital. so old, in fact that I joked that it had every level of asbestos awareness from "Warning! DEADLY ASBESTOS" to "Careful, there's asbestos", to "eat more asbestos!" to "Coming soon...asbestos!". :D

2019-02-20 03:41:51 +0000 UTCThe lens is what's known as a "Bioconvex" lens and is made for a fairly short focal length. So, the projector must have wanted it to be defocused at the distance being used.
