You could replace the body with a Leef body designed from the ground up specifically to hold an 18650.
harddrive said:I have the new WE cree in my 6P with a 17670. It seems just as bright as when the same drop in is in my WE D2 with a 18650. As you mentioned runtime is less with the 17670. I havn't done any test but I would still expect it to be pretty good. The 17670 has about 1/3 less capacity that the 18650. My maths say you should still get a couple of hours of regulated light and a bit of unregulated after that. Plenty for me. If you need more carry an extra 17670. The other option of course is to get your 6P bored to accept a 18650 cell. I believe CPF member "Highorder" will do it for a small fee. Those Leef bodies look great but it is a lot of money. I got a 9P body bored to fit 2 x 18500 cells. It cost me $15 AUD (about $11 USD or so) at a local engineering shop. Was money well spent. I am thinking of getting my 6P done as well.
By the way, I really like te WE cree drop in. Nice and bright with great throw.
Anyone know if a SF 6P will accept a 18650 cell? Found diameter specs for the cells, but not for the interior of the 6P. Thanks!
[font=Arial, Helvetica, sans-serif]The trouble and cost of "upgrading" to an LED drop-in for a 2xCR123 incan light is also often more than it would be worth t[/font][font=Arial, Helvetica, sans-serif]o just get a recent CREE-based light. Eg.,Output: The white light produced by the LED appears ever so slightly purplish relative to direct sunlight, but you'll never notice it in actual use. In a dark room it appears pure white.
By my estimates it is producing about 139 lumens on the High setting, which means it outclasses both the P60 and the brighter P61 incandescent modules used in many Surefire 2x123A lights in terms of lumens output. It also beats them in runtime. It runs for about 1.5 hours regulated with two 123A cells while the P60 runs for about an hour with declining output, and the P61 only runs 20 minutes. By the way, the Low setting with 123A cells produces about 13.9 lumens. See this page about how I calculated these lumen estimates.
With 123A cells, output is regulated until the batteries can no longer supply enough current. It can also use 18650 rechargeable 3.7V Lithium-Ion cells (commonly known as the Pila 600P) to produce diminishing output over time, but longer runtimes....
