cheesehead,
lamps are in general non-linear circuit elements, i.e. their resistance is not constant. The tests on the 1185 may not be representative of other WA lamps. Who knows, but in any case I am going by the WA re-rating formulas for the most part, or when they are absent, my guessing was informed by my past experience with them. Please feel free to post numbers which are more accurate in regards to pushing the 1164 or 1111. What do you think the current will be at 7.0-7.2 volts?
As for NiMH and recharge cycles, the latest cells I have looked at were rated for 1000 charges. Not bad at all.
And I must stress again that we are not even coming close to "pushing" the TL battery pack. 10 amps would probably do that. 4 amps won't.
Finally, I have to agree with you on the question of at what point a TL is no longer a TL. I was actually musing about that very question last night. Certainly, if all we have original is the shell, it's a mod and not an upgrade. However, the battery pack change to 9 cells is only ONE of the possibilities here, and even if it becomes my favorite idea, I will DEFINITELY be offering a simple WA bulb upgrade. This is a drop in upgrade to the light. I mean, we all change out the reflector and lamp every single time we replace a bad LA. Suppose TL comes out with a better lamp, which they plan on doing, is my TL no longer a TL because I've changed out the lamp and reflector?
In using a Carley 1940 reflector I am essentially using the same reflector geometry that TL uses. Both have almost identicle measurements. The main thrust of this is for me (with as much help as I can get--HELP! HELP! /ubbthreads/images/graemlins/smile.gif ) to do all the leg work and R&D and prototyping so that anyone can drop in the final WA/Carley lamp assembly and have a super bright TigerLight with reduced run time. My idea of making the assembly with a removeable bi-pin socket is so that people can replace the lamp without having to pay for a new reflector, and so that people can adjust the socket in the reflector to obtain the beam profile they desire. It will arrive all set to use, however, and a person could just leave it that way and insert and remove the bi-pin lamps in exactly the same way that they do with the MC.
But even regarding the total "upgrade" or mod to the 9.6 volt WA lamp and 9 cell battery pack, the appealing thing is keeping the same external light and charger (which many of us like a lot) and only having to buy a $25 battery pack, $10 wall wart/charger mod, and $15 lamp assembly (with a low $3 lamp replacement thereafter). So, in other words, for about $50 someone who owns a TigerLight, could rev it up to something brighter than a SF M6. It wouldn't really be a TL anymore, I suppose, and the simple drop in lamp/reflector mod is more appealing in many ways, but still, it's all in good fun.
Moving on, I will start looking for a cheap and suitable wallwart and order the supplies to make up a KAN 1050 2/3A 9 cell pack. This will keep me going until the WA and Carley orders come.
I also am going to take apart the stock pack to try to figure out exactly which 4/5A cell TL uses. I would like to make up a standard configuration pack for the TL that uses premium 4/5A cells if the stock pack isn't already using them. Each month seems to bring newer and better NiMH batteries.
And if there is any interest at all, I am willing to make up 9 and 6 cell battery packs for the TigerLight, as well as modified charging harnesses and wallwarts. Costs to be determined, but the figures I mentioned above are probably in the ball park.
