Well, I have an update on the status of my personal collection: it has just grown by 2 lights and three battery compartments.
As I've often posted, I purchased a Ra Clicky 140n about two years ago. It replaced an older Gen. HDS EDC 42XR [with Arc 4+ clip and SSC P4]. IT has been my steadfast companion and EDC, in activities ranging from reading books, taking out the trash, to camping, hiking, swimming... And has never had so much as a hiccup through all my abuse. I recently had Milkyspit modify it with a 5000k Cree XP-E [rather than XP-G, I like the tight beam of the Osram GD].
Via PM over int he marketplace, I arranged the purchase of two HDS heads, a 100 HCRI and a 170n, as well as a 17670, CR123 and much vaunted 2xAA battery compartments. I just recieeved these today, and, as usual, I am amazed at the fit and finish of the lights and battery tubes. Truly stand-up work, Henry.
First impressions:
100HCRI head: Beautiful beam. I can understand why these are so sought after. It may be "only" 100 lumens, but they are the nicest, deepest, clearest lumens I've had the pleasure to use. The SSC P4 has a very white hotspot, which fades softly into the spill beam with a golden, sunset colored ring of light. Absolutely beautiful. The hotspot has reasonable punch, but the spill evenly and gently illuminates everything else within reach.
170 head: Much like my 140 [with Osram GD], tight, punchy hotspot with much less intense spill. Hotspot still has a very nice transition beam [from the center of the hotspot to the spill beam]. This one appears white, a little colder than the XP-E in my 140n, without a serious yellow or green overcast, as mine had.
17670 body, 123 and 2xAA. Well made. Slight visual differences in ano and knurling (as compared to the ano and knurling on the head and battery compartment of my 140n). Slightly more, well, slippery feeling. Biggest differences otherwise? Both heads have a higher serial # than my 140 does, and each tailcap uses a different type of rubber switch cover. IIRC, it's the same type as on the older EDC series lights, and not the seemingly heavier "rubber" boot of my 140n. Each has minimal "bump." Would probably tailstand quite well in comparison to mine [I don't do that, so it's not a problem either way for me].
Also, the switch itself is the same as the switch as in my 140n's battery compartment, but each of these also has a small amount of clear epoxy/resin surrounding the switch and fastening it to the PCB it is on. That is my one apparent "flaw" of my older 140n. I was always a bit concerned about horizontal shock breaking one or more of the legs of the switch. The resin appears to resolve this problem.
The 2xAA battery compartment seems to work well. Threads match, switching works. However, with just a cursory moment of use, it appears that this is a case of the head being "so smart, it's stupid." I popped two fresh Li primaries into it, and it appears that their higher initial voltage tricks the head into thinking it is a partially discharged Li-ion battery. It starts out momentarily at maximum [if that mode is selected], then it appears that the current draw drops the voltage quickly enough that the head believes the "Li-ion" cells to be discharged, and begins blinking down through the levels of output, much as it would with a dead battery. I am going to play with it more, but I doubt that Ni-MH will cause the same problem.
Working from memory, this would not have been a problem for a EDC series or Novatac light, as the user must "tell" the light that it is loaded with a Li-ion, and must protect it. Perhaps if Henry has plans for 2xAA battery compartments in the future [fingers crossed, prayers sent] he could install another programming sub-condition into the options menu to tell the light to momentarily ignore the higher initial voltage, and thus prevent the light from being confused between a pair of Lithium primaries, and a Li-ion cell?
Otherwise, all is well. Loving the lights and hoping to be able to post some pics.

On another topic, ie: the cracking boot covers.
My older 140n's boot cover is made of a thicker/heavier rubber material. It has suffereda large amount of surface cracking, primarily, I believe from using my fingernail to press ont he boot cover, but these are merely surface cracks. They seem to have come to a certain point, and are continuing no further. Just to alleviate any and all concerns about potential future troubles. Also, the different/older type of polymer-like switch boot I mentioned on each of my new battery compartments: As stated, I had an older HDS EDC series EDC B42XR with the same type of switch boot. It suffered no cracks, even though I thoroughly "abused" that light in the period I owned it, and had none when I received it [at which point it had seen use for several years previous].
