Okay Matt I got one for ya, no better place to make this post.
Several years ago I picked up an Eveready circa 1937 brass and copper flashlight. I have not yet been able to find the exact model # for the c sized cell version.
I picked it up at a local flee market for oddly enough, 10 bucks. Now you are probably wondering why I am writing this in a P60 thread. Well, in an ahhh-haaa moment I had one evening while looking at the light on my shelf it came to me that I should upgrade the vintage piece. Cutting a long story short, a p60 host fit perfectly after removing the stock reflector and catch piece (both of which unscrew out).
Two small issues plague the upgrade. One I resolved and the second is further complicated by the first resolve. Here is the low down; If you notice in the pictures below i show some rubber washers and the inside of the front of the light. With a small piece of copper and solder I extended the original switch about 1/4 of an inch so that it contacts the reflector to complete the circuit. Unfortunately for the setup to work I had to isolate the drop in with the washers. Not good for thermal management but the XRE emitter didnt seem to mind. I also placed and XHP50 P60 drop-in in it which really made it come to life but will quickly overheat if left on for too long.
The batteries, a single 18650 with rubber grommets or an 18650 + 18350 with grommets worked great to power the light (XRE n XHP50 respectively) with the addition of a tail cap spring borrowed from a mag light.
Also tmart . com sells the Ultrafire C1 host for 9.99. (or used to anyway) Personally i like the C1 alot. There are several variants out there and if you buy one of the 9.99 hosts maybe you will luck out and get the longer front bezel and linear driver capable of powering an XHP50. just swap in two 18350’s and solder in an MCPCB XHP50.
I have a few p60 hosts, because it was the easiest way to upgrade a flashlight without soldering (started with flashlights in the days the 105c wasn’t launched on the market or wasn’t really popular nad the BLF didn’t exist). 1-2 years later the 105c becomes available, but I still like the p60 hosts and solder in this driver.
I had a few Ultrafire 501, 502, 504, two Solarforce L2, L2m, L2p (blue and gold), grey L2n, SkyRay SR-5 (the copy of the Seraph), but never a genuine Seraph SP-6.
The 501 is really cheap and I do not like the quality. The 502 is better and with the matt coating looks really good, I don’t the clip (not really stable and if you remove it, you got two screw holes, which end in the battery tube (easiest way: glue to close these). The tailcapdesign is not the first choice (in my opinion).
I prefer the Ultrafire 504 as a cheap near $10 complete flashlight (it was my first 18650 flashlight, bought with a XR-E LED, still used, stable and a big plus: Do not roll around). If you have a little bit bigger budget, go for a matt L2 (a higher quality as the 504). The L2p is nice, if you look for a special color, but the L2 is good enough.
In my view a great budget P60 host, if thermal conductivity is not critical for your drop in. Host takes 18650 cells, also protected ones due to double springs. The switch is reverse clicky, and takes a lot of force to actually ‘click’. I do not expect this to turn in on my bag or trousers by accident.
I like that the nylon body does not feel cold in my hand when using it outside while camping in cold weather.
