Hi! Haven't posted here before but maybe you guys have some good advice. I'm on a job at the moment, they've given me an LED security light to wire in, I've never used one of these before, lo and behold it doesn't work. Derp. It lights up but flashes on/off about once a second. It's rated for UK mains and draws 50 W so I reckon it's some problem with it's transformer. Any advice? It's got no dimmer (I know about LEDs and dimmers), its just on/off.
