edited to remove incorrect reference to tip45 fuzzy image my mistake

[Gin Malinko]

nope, this is infact a tip42 pnp. im 100% sure

looks like it says TIP42 to me

[Gin Malinko]

okay here are some pics of the blade. and you can see that it is not all that bright. infact the only time you can really see it well at all is in pitch blackness.





btw, im not the one that took these pics, so not me in the pic.

[Arkhan]

that is definitely not right for a p4 white.

The p4 white, properly driven, should be in the "brightest tactical flashlight" range.

I did have a BAD tip42 from the Shack earlier this fall. just wouldn't put out. I replaced it and presto, solved.

Hi, I am new to the forums, but I got a couple questions one in Gin's drawing and pic I didnt notice a resistor, could that have something to do with the p4 being as bright as it should?

Also in one of the threads I was reading, talked about alkaline not being very good to use and a lot of talk about using NiMH, Lithium, or Li-Ion, if he is using alkaline could that effect the brightness?

Welcom to the fourms, Keladis

Alkaline batteries, in this case I do not believe would have such a detrimental effect on the brightness, only in much higher power applications would alkalines be bad, for example in a CF saber running a 10w LED.

Thanks for the welcome, and yeah I wasn't sure if alkaline batteries would cause it or not.

lkalines do not output enough ma to properly drive your led u need nimh lion rechargables or lithim primary disposable especially aaa but also aa depending onyour series parallel config . also one of the last two tip42g igot at the shack was flaky and i had to replace
