Romisen + P60 dropin + 18650 AW protected ?

Wich Romisen model accept P60 style led dropin and AW protected 18650 ?

I have several P60 dropin (Q5 WC 5 mode, Q4 WC one mode, and others) and I want to use them in a 18650 flashlight.

Actually I use them with my Surefire M2, but it only accept 17670 cells.
I have some AW 18650 cells, and want to benefit from the extra power.

I want to buy a Romisen, because the RC-F4 I've buyed from Dealextreme is excellent. The only lack is that AW RCR 123 don't fit.
Have buyed 2 pairs of trustfire sku 8683 to resolve this problem.

Thanks.

The Romisen RC-M4

I ordered mine last friday, I wanted to jump on the 18650 bandwagon too

N00b question: Where do you get P60 drop-ins?

x2 on the RC-M4. I've had one in my shopping cart for a couple weeks. I'm just waiting for my 602d HAIII arrive since I don't like to have too many orders due from DX.

The RC-M4 and RC-E4 both take P60 modules, but the RC-M4 seems to be the better one(post with a pic).

Yeah, I've been hearing that protected 18650's are a tight fit in the RC-E4. I would just treat the E4 as though it won't fit them.

Has anybody seen gray Romisen RC M-4 ?

Yes I have one. I would have preferred black but didn't know it was available.

Thanks for information.

I'll buy a grey RC-M4 in some hours, but I want to replace the standard black tailcap with a GITD tailcap.

Do you know wich GITD tailcap fits perfectly in the RC-M4 ?

The RC-M4 is a better host than the RC-E4 or WF-501B which looks almost identical to it. The new RC-E4 lights do take protected 18650 cells, but the lens doesn't have a threaded retaining ring. The lens is loose and can fall out when changing modules. The old WF-501B had a threaded retaining ring, but it now has a glued metal ring so you can't upgrade the lens or insert a GITD lens o-ring. The WF-501B is a 2XCR123A light and doesn't take 18650 cells. The RC-M4 is available in black or silver, and I have both. It takes protected 18650 cells and has a threaded retaining ring holding the lens in place. The standard DX 16mm GITD silicone switch covers fit fine, and none of the M4 is glued.

I have not seen any disassembled M4 pictures. The style of M4 closely resembles 501B light. Does M4 come apart just like 501B ? My latest 501B has replaceable tail cap but the lense seems to be glued in. Unfortuantely, the battery tube is very thight even for protected RCR123A, so you can forget about 17xxx or 18xxx with the 501B. However, it is a great incandescent light for under $10. The light output (on 2x RCR123A) is even more than F4(on 17xxx). 501B is my first incandescent light after becoming flashaholic and I am glad that I purchased it. Of course, I have already ordered the R2 drop-in and would try it on the 501B.

the O-ring looks more like 1" (25.4mm), DX doesn't carry this size. Lighthound does but they want $6 to ship.

No, but the 24mm can be stretched over a larger object overnight if you need a larger diameter...

Corrected my error above to reflect that I meant 16mm silicone switch covers fit fine. Re: lens o-ring, I stretched the 24mm from DX overnight non the head of a WF-600, and it fit the RC-M4 after that. It also fit the old model WF-501B with a threaded retaining ring, but the new model has a glued retaining ring under the lens.
