I've just fitted one of these
and something odd happens.
With only one bulb plugged in, that bulb is very bright.
But the more I plug in the dimmer they all get, and when all 6 are connected they are all really dim, so the overall light is less than a single bulb.
There is no additional transformer, I just connected it straight into the ceiling rose as you would a normal light.
Anyone know what is causing this, or is it just defective.
