1. Thanks Clive, A right riveting read Actually it may be relevant as the LED driver pictured on page 1 is the one (or very similar) we are using. I realise that CE could mean 'Chinese Equivalent'.

2. Yes Nick, I realised that. We still have tests to do to see temperature rises, but the LED is on a heatsink with plenty of free air (a fan would detract from the artistic aspects). As far as melting is concerned, I have no worries over the cast iron or bronze, but start to get a bit wary about the aluminium. My main concern is the driver and LED chip going pop in flames. There is a 20mm fuse holder which will be furnished with a 1A glass fuse.

No I am not being sarky! I am just knackered after a hard day watching my son do some grafting. I have just had to resort to painkillers (Bacardi and coke). Thanks mates, for taking onboard this issue and providing me with some meat to chew.

Cheers,

Rob
