Electrical product advice needed

Yes, I take on board these comments. First of all the cover was 3D printed to give a pattern for casting in bronze, which the one in the photo is. Secondly the fuse/connector block fixing screw acts as an earth point as the earth wire from the driver cable is connected to it. In fact, the earth wire connected to the driver fixing is redundant. The driver itself is two-wire and thus I presume, double insulated. Finally, the cable is a prewired one with one end stripped and crimped and a moulded on plug and switch, which I did not want to remake, but I understand your concern.

Hi,
We have done some testing on the unit now and it is not good. The driver gets too hot. The steady state temperature is reached after 45 minutes and is 50 deg C on the top of the casting above the driver. The baseplate is too hot to touch. Even if the unit remains electrically stable, at that temperature it would damage the furniture it is on. The two units we have tested give similar results.

Clive - your suggestion of a wall wart or separate power supply like this one http://www.ultraleds.co.uk/white-60w...ed-driver.html is looking the most sensible way forward and I will be talking to ultraleds on Monday.

Cheers
