P91

Re: P90

It depends on how you treat your lamp assembly. I have several LA's that keep up the brightness pretty well. On a longterm the glass envelope starts to get a bit more cloudy and with this looses some of its punch.

Let me take a picture of a fully working N62 - well sort of working. /ubbthreads/images/graemlins/wink.gif

Re: P90

oh.... how to take care? if the lamp gets too hot(like puting a torch facing down while its on), will it dim down the brightness?

Re: P90

I use 3 sanyo cr123 (brand new) on the p91 to burn in the blub. I leave it on lying flat and after after 10 mins the light was off by itelf. the entire 9p is so hot that i can't hold it for more than 5 secs! I let it cool down for about 20mins and then on again and this time the beam is slightly yellowish...
