"All in all very easy to install and good value. I was very impressed until coming to fit the lamps I had ordered alongside these fittings. In a few fittings the lamps fit in like a glove but for the other 60% the lamps failed to fit properly into the lamp holder without what seemed to be damaging the lamp holder itself. This could cause problems for my customer/me in the future when lamps need replacing. so all in all what seemed to be a great fitting didn't really have the basic principles mastered."
