Old4570, you're perhaps the most venerated person on this board and a wealth of knowledge. Sometimes though I think you are short on words (something I'm never accused of!) and I'm left begging for more. This is one time where I'm going to hopefully re-open an intriguing topic you opened on Jayki, unfortunately not helped by the picture hosting place you used at the time (picturegood.com), seemingly defunct or at least my dns servers don't know of it.
I hope it's okay to copy your own post to here and hopefully get more discussion.

Best P60 Host
Recently Ive been playing with my lights , and using some older lights , I have been able to drop in some left over P60 pills into non P60 hosts ...
1st on is my old Romisen RL-B7 , http://cgi.ebay.com/Romisen-RL-B7-7w-7-Watt-Luxeon-LED-Flashlight-FREE-S-H_W0QQitemZ160347494341QQcmdZViewItemQQptZUS_Flashlights?hash=item25557497c5

The other light , is my SAIK SA-8 , pulled out the reflector , and light pill , then widened the spring on the P60 drop in so it would grip the body and now my SAIK is equipped with a P60 drop in ...
Now you may wonder why do this , and the answer is output , both these lights offer greatly increased output over say a Solarforce L2 Host Body ..
For some reason most P60 hosts seem to block a lot of output , and with these two non P60 hosts , they dont seem to block output anywhere near as bad , hence the greater output .

So, yeah, I did my homework (that and a lot more) before posting, but keep coming dry.
No being an owner of any of the flashlights mentioned, could you (and anyone else) indulge us as to the particulars of (what I assume you to mean) fitting P60 pills inside these flashlights' bodies? If I could put in a nice XM-L drop-in pill into one of these bodies, for instance, I could have a cheap "candle mode" flashlight option (run the flashlight with no head or reflector), as well as how you mention, possibly less light blocked by the P60 host design. This very well could be what I've been looking for, at about half the price I planned (not wanting to buy another $35 flashlight, and already having the drop-ins).
Also, simply replacing the pill with a good one from a P60 drop-in would seem to address the biggest issue with at least the Saik SA-8: atrocious heatsinking (or lack thereof).
I'm partly confused because all P60 drop-in pills I have are only threaded about halfway down the pill. That means the pill needs to screw INTO something, not 'down onto' something like a C8 pill would. With the models you listed: DX "10W K2", Romisen RC-E4, and Saik SA-8 (other compatible models welcome), it would seem to me the pills all screw 'into' those bodies. So how do you make them fit? Not owning these, it's hard to visualize. And which would you recommend most for this?
BTW, if you need it, I found postimage.org to be an easy, no-frills, direct-linkable, no-registration site to upload/link to pics, and seems pretty reliable (not sure how they make money-no ads).
