It took me a while to move away from GU10 in a can, for the cost & availability in years to come. I settled for the Collingwood H2 Pro, which I’ve been fitting for about 3 years now. I have to say they are brilliant & I think I’ve had only 1 failure. They have a 7 year warranty & the price from my local CEF is very competitive.
I have a few customers who have had previous sparks fit JCC’s, they are complete c**p by comparison & are failing fast! 1 unlucky customer has well over a hundred of them in their new house, with no warranty due to builder issues.
