Hi im new to this forum, i need some help i recently brought some led strip lights they are 12v lights i brought 4 strips of them. the problem is when i wire them to a 12v transformer and plug them in they they flick on for like half a second as im plugging them into the wall and then they stay off. the fuse in the plug is a 5amp. is there a reason they are not working.

What kind of transformer do you have for it? 12v DC stabilised or a 12v electronic transformer?

 

[ralphsvivariums]

its a 12v electronic transformer

load might be too small alright for the electronic

You will need an LED driver ~ either constant current or constant voltage, dependant upon the LED configuration,

see example below(from our favourite supplier)

LED's are the same as diode's and should be working on DC only they will start to emit light @ 0.7 of a volt dc @ 0.02 Amps per LED, SO make sure that its DC and not AC you are supplying the lights with. because they are diodes you should not have damaged them as long as it was only a 12 volt ac transformer. DIODES let current flow in only one direction hope this help's you. look up full wave rectifier and you will see why they flicked on.
