Looks like there's some interesting discussion over Walter's Thread =
http://forum.lowyat.net/index.php?showtopi...160&p=31638960&AW thermal protection works? I was always sceptical about it.
Lol. I dunno if thermal protection works or not but over-discharge definitely does.
That day ShinnX put a dead battery in and it lit up, flickered then turned off.
Regarding the MiNi's heat on li-ions
Quark 123 Mini_High_________200__turn-on_____________1XIMR16340_________________________ ________,

Quark 123 Mini_High_________190__120 sec____________1XIMR16340_________________________ ________,
Tested by MrGman.
Using CREE's datasheet, 190L is 95% of 200L, which we shall assume to be 25ºC junction temp.
For the output to drop to 95%, the junction temp should now be between 40 - 45 ºC.
That's after 2 mins. So dun worry about the 1 min will degrade your LED nonesense. =D
As to how long you can use it b4 it overheats, no one knows. Haha. =D Use with extreme caution.
The heatsinking of the MiNi appears to be excellent but there is simply not enough material to keep all that heat. =(

Ok guys.. before all that..
I have a HUGE problem with my P7. I was being curious so i jsut put my M6+P7 into the pail of water for about 20 seconds.
And when I took it out, there was not only vapour in the lens but a POOL of water!!
So i opened every connection, re-lubed it and tested it again..
THis time for only 10 seconds while shaking it in water... Same thing.. Water seeped in and there was still a pool of water.
Here are some pics of it

After having a good look at it.. I think the problem is here.. the o-rings below the lens is not in position..
Have a close look to it and u might see what i mean. Could someone help me out with this?? I cant seem to separate the reflector from the lens.

If u can see, on the relfector there is some water mark.. I do not know how to wipe them. HELP!!
Could I bring it to someone's house?? Then i could see how its done...?
Added on February 2, 2010, 5:32 pmWow.. thanks man!
I think slowly im beginning to see the different view of my P7.. Cause initially i aso wanted something with a decent runtime and something bright. So i believe the P7 fits the criteria..
MAybe i was too hasty in judging the infamous P7.. haha
I'd suggest looking for the person you bought it from. =D
