I put one of those excellent USVOI Seoul P4s' from Photonfanatic in a new L1 (current style) and I LLOOOVVE it. Brightness on high more than doubled. I'd put it around the 60 lumen range. Low is a little brighter but not too bright, about 5-ish lumens. I can't put it down! If anyone is considering this mod, don't hesitate! Its' my new EDC. I don't know if I will but a McR20 Seoul in there, since I like the throw it has, besides I don't think it will fit since the L1 head is shorter. Just my 2 cents!
