cheap 12V garden lights!

[aidge]

Got called out to look at 12V 20W plug and play garden lights with MR16 lamps that are working at varying levels of brightness. Before i start taking everything apart anyone got any ideas on what would effect the lumin output of different lamps on the circuit or is it likely that its just down to a cheap set performing at different levels?

at a guess, poor connections to the fittings. either the pins on the lamps corroded, or, some are spiked onto the highway cable just by spiking through the insulation. these give terrible connections.

I take it the differing level lights are random, and not in one area. If so...... what tel said.

Thanks guys!

corrosion is always a huge problem when you get 12V and damp combined together. might think you've found a CuSO4 mine.
