Re: Re: Brightlightz led GU10s

It was a bit of surprise when I finally twigged that these highly
efficient lamps that run so apparently cold are susceptible to heat from
the driver electronics. As a consequence, I've been very selective about
choosing what appear to be good quality ones, but it's too early to tell
what the long-term prospects are for them.

Quality heat sinks seem to be critical, but the lamp fitting's ability to
dissipate heat must play a part, too.

I've settled on Aurora lamps for now and have 16 of them so far. One failed
in 24hrs, which was obviously an anomaly.
