Re: Yet another LED GU10 thread...

["Howard" <howardsixtynine@xxxxxxxxxxx>]

I actually tried a very similar lamp from Brightlightz a while back.
It was=
a 6W, 27 x 5050 LED one. I thought it was rubbish and sent it back. It was=
nowhere near as bright as a 35W halogen, let alone the 50W-60W that they c=
laim. The 29 chip one is supposed to be 20% brighter, but I'm surprised it
=
makes that much difference.

Are they really 7W? I'm coming to the conclusion that dissipating more
than=
4 or 5W in a standard size GU10 while keeping the LED junction below a rea=
sonable temperature is pretty difficult. I suspect that the 5W ones that I
=
bought may have deteriorated so fast because the LEDs are running too hot.
