Hi All,
Thanks for the feedback. At the moment they haven't decided to switch off, so with the old saying 'if it aint broke......' However WHEN they do I'll try some of the recommendations. Probably the socket is the 1st thing I'll try as it will be the cheapest. I like the LED idea, but they're not cheap at around $40 bucks a pop. Also, the white light will make it look a tad sterile - maybe they come in that warmer incandescent color ?
One thing is for sure the heat generated is is huge. Found out the nasty way when I had a momentary lapse of concentration - ouch!
Certainly anyone contemplating getting them, do some research there are pro's (looks nice) but just also some cons.
