I don't know about any new White LED this year, I'll look into it. Last year when they introduced the SilverTech scales (that was last year wasn't it?) they introduced a nice new white LED, larger in size, but they fit it into the 58mm Silver-Tech scales.
I'm guess it's about 5 lumen, but I've not compared lights for a while. I think it's brighter than the in-line LED module which has always been white, but I can't remember what I said about that at the time. I'm pretty sure I said the new one was brighter.
I heard that they would be putting this into some other 58mm knives like the Midnight mini champ. It would cool if they could have both red and white in the mini-champ, but I'm bettin' it's not happenin'.
I do occasionally use the White LED on my silvertech mini-champ, but I find my other pocket lights generally more useful and easier in most cases since on the SAK you have to keep the button pressed to keep it lit. Even the latest Photon-Freedom keychain light is better. Now if they managed to put the Photon UI into the SAK that would make it 100 times better. Still for emergency use it does come in handy. On the 111mm though could get a real photon in the scales if they tried.
