I'd been looking for shallow mounting depth, warm-while light fittings and thought these would fit the bill perfectly. In all aspects these lights have been a massive disappointment. Firstly, the cutout needed to be re-shaped to allow the hinges to fit. Next, the connectors from the (included) transformers didn't match those on the fitting, necessitating cutting them off and soldering. Finally, two of the three fittings expired within a several days of installation. Incidentally, as the connectors did not match, I emailed the company wanting to know if they were indeed the correct ones, but received no response. I have since removed the fittings and am sending them back for a full refund.
