LED retrofit ring and driver for bulkhead style lights.

I'm guessing this LED panel is primarily intended for retrofitting in traditional fluorescent and tungsten bulkhead lights, but it could also find use as a backlight in a lightbox. It's not got an isolated supply, so it should be regarded as being live with reference to ground and mounted in a manner that does not pose a shock risk.

In Europe the Quicktest is available from most large electronic component suppliers like CPC, RS, Rapid Electronics etc.
