Pros: P-4 is a good upgrade, or a mod for
older lights.
it has a bright white light.
also a good led upgrade for the first
time modifier.
(like i was when i used it)
it's very affordable.
fairly easy to mod if you can do
basic soldering, and some epoxying.
comes polarized on the aluminum 16mm
disc/base.
still easy on batteries if using an
exsisting driver in the modded light.

Cons: the P4 is getting "old".
(i still like the P2 in the RC-G2)
there are better upgrades now than the P4.
not much else.

Other Thoughts: the Q5 is the hottest emitter for modding
upgrades on a 16mm base right now.
i'm still holding out for the R2 to be availible on the 16mm base.
i put this P4/16mm in my test mule RC-G2.
it wasn't a whole lot brighter.
but it was brighter.
seemed to use up the battery just a tiny
bit faster.
like a few minutes or so is all.
great for projects like outdoor lighting,
or remote area lighting.
mind the voltage to 3.5v or 4v,
and heat sinking is needed.

Bottomline: good cheap, quality cree led.

Pros: Very bright, amazing price, small MCPCB it's mounted on, and easy to use. Perfect bin number. Not too warm, but not very cool white either, just in the middle.

Cons: Soldering onto the MCPCB is difficult because it's pulling the heat away before you solder. I just turn up the heat on my iron and I'm fine.

Other Thoughts: I'm using these in multiple automotive applications and they are great. Once you properly figure out heat management, using them is a breeze.

Bottomline: Amazing price for these quality LEDs. Anyone who doesn't jump on these surely isn't right in the head.

Pros: A bright light for my led flashlight
#6145 the lens fell out of that one. A good price and a pretty good fit too. Easy sauter points, and no sanding down. Seems to be a good tint.

Cons: none

Other Thoughts:

Bottomline: A great price for a good cree, tiny pcb and aligned screw holes, good tint, may need more.
