All the bulbs I've had so far were direct from lumicycle, so should be fine.
These cheap jobbies were from Ikea, but aren't suitable but should make a
great outdoor lighting.

Come on you lot! What sort of power connector is it that lumi use? 2.1mm DC?
2.5mm DC? I really just don't know! And can I buy the bits that the bulbs
plug into off the high street?
