Klaus:
The 02178 is the most efficient of a bunch with L/W efficiencies between 18.0 and 24.6. I think you're right. that 240 Lumen light should easily run for > 90 minutes.
Here's a copy of an email I sent to WA technical customer service.
"Hello:
My "Flashaholic" associates on the CandlePower Forum and I have several discontinued Energizer Double Barreled Flashlights and current and discontinued Underwater Kinetics Dive Lights that use hard to find T-2 1/4 bulbs.
Will you please advise which OEM's or dealers currently resell the following WA lamp numbers? Alternatively, do you have odds and ends in stock of any of the following bulbs which you'd be willing to sell below your normal minimum order size?
02186 (Suspect this former Energizer OEM bulb)
01183 (Suspect this current UKE OEM bulb)
01319
01307
01148
01315
01124
02178
01288 (Suspect this former Energizer OEM)
We look forward to your response.
Thanks for your consideration."

ihate to say this but quickbeam will tell you that i had this idea 3 or 4 weeks ago- i had parts and all on my workbench . lets say great minds think alike shall we
i highly comend you for
a. doing this on your own
b. doing such a proffesional job( at first i thought it was factery made)
im honored that i had a part in inspiring you. keep it up. well beat the makita yet.
and take those silly rubber strips off. they peel right off.
you may name it what you wish but ive dubbed my 4 aaa "sting" after frodos(bilbo) sword. it was smaller than anduril but deadly all the same and lit up when danger was near.
good job!!!!

Now let's see -- Is it "1" that comes before "2" or is it the other way around?
Pretty sad when I transpose the same two numbers twice in a short list. I wonder if I'm in my second senility or just having a "senior moment"
Thanks for proofreading.

Got the page built - It'll be posted either by 8:00 PM tonight or if not, Sat morning.

Here's the Response I got from WA. Ms. Killmore isn't answering her phone at the moment, so I don't know what the per bulb costs would be.
Does anyone else want to join in on a group purchase of T-2 1/4 bulbs from WA. Their minimum order is $100, and I don't yet know what the individual bulb prices are.
Besides the heavy hitter bulbs for the DB 8AA and the DB 6AA, here are bulbs that might interest people for the DB 4AA set up in serial:
01307 4.8 V 1.1 A 5.28 W 104.3 L (would be 10% underdriven with Nimh and probably just right if you used Lithium)
01319 4.8 V 1.92 A 9.22 W 203.6 L (would be 15% to 20% underdriven with Nimh's and probably a little underdriven with Lithiums.
"Dear Mr. "Lemlux",

yes.3 or 4 in 6v.
Phred:
If we get enough interest to order, we should each be specific with how many lamps we want of each specific part number. See Klaus WA link reference to look at the WA table to choose which bulbs running at about 6 volts you want.
I'd probably be willing to squirrel away another 3 or 4 lamps myself. I have a second DB 8AA in mid transaction now and hopes for a third. My DB 6AA is in transit to Aragorn's mod factory now with the P91 assembly, but I also sent him quick disconnect wiring so I can switch back and forth between P91 and the T-2 1/4 of my choice.
Sounds like we can cover 7 or 8 lamps even before Klaus reserves his favorites.

lemlux,
I would just need/want one or two of whatever 6.x bulb makes most sense - possibly your originally proposed 01148.
As I even have no 6AA / 8AA at hand I´m not too much under pressure to get those bulbs - for the moded 4AA / 4AAA I think the ones I use (6AA and 01307) makes most sense to me.

Oh and yes,
regarding the DB AA bulb setup - actually some of them will drain even the new nice 1800ma AAs very fast - but as good as 123s are fitting the A-sized cells will too - the normal A type NiMhs are available upto 2700 ma and are 17 x 50 - nice fit - just replacing one AA and geting rid of the plastic ring at least for the 4AA. Did anyone tested the space in the 6AA / 8AA ?
If you need max runtime and not max voltage even three of the 4/5 AF sized ones would fit in the 8AA and give a setup of 6 cells at 4000ma using the Sanyo Twicells .... not too bad comparing to a 6AA with AAs at 1700/1800 or the AFs in the 6AA at 2700.
Two hours runtime using a 260 lu bulb

It seems like every time I get close to deciding a course of action you open more doorways I didn't know existed. I love it!!
Thanks.
BTW, I just read your string on the project potentially using various low double digit numbers of AA Nimhs to get 1200 + Lumens.
This makes me think of one of the major items on my wish I could buy list. My preference is plug available components together. Why haven't people come up with a small ergonomically comfortable flashlight that uses a 7.2 V RC pack of 6 3000 mAh Sub C batteries that drives a WA 01148 bulb?
The design for the bulb is
6.3V 1.95 A 264 L 140 hours.
The RC pack might give the following results with a run time of > 75 minutes.
6.7 V 2.0 A 324 L 70 hours
6.9 V 2.0 A 368 L 45 hours
I would love to have this in a package that looked like the little brother of a PT 600.

I have seen the thread where someone drove a 12 V Halogen off of two 7.2 V RC packs, but I never read about a flashlight case that held one pack, two packs or the lamp unit.
Can you advise where we can find 2700 mAh NiMh A cells on line. I can't seem to search my way there. I wonder how much more expensive rechargeable A cells are than the AA's

Yep, this is what I was/am working on. I am actually trying to see what I can do with one 7.2v RC pack. I've been trying to find a 6v MR16 or MR11 halogen lamp, but they seem to be hard to find.
Its been quite difficult to find a case which will hold 2 RC packs, short of one of the larger lanterns made for the bigger lantern batteries. And I don't have much access to raw materials like aluminium tubing etc which would be best..
Anyway, for your info, these RC packs are very powerful - Nicad ones rated at 2400mah are very good, although fully charged they actually go up to almost 8v, as each cell fully charged gives about 1.3v (under load!)
I haven't looked at using anything other than MR16 lamp assemblies, but perhaps if I can find some I might try an SF P91..
One other thing - there are also 8.4v and 9.6v RC packs available here, in smaller sizes - some of the smaller ones are used for Airsoft electric BB guns (but thats a whole different story..)

I hope your search to become a successful hermit crab with the RC packs and lamps is more creative or serendipidous than mine. keep us up to date with your progress.<HR></BLOCKQUOTE>
Thanks. I guess I could post photos of what I have now - basically 2 RC packs wired together with a switch and a halogen lamp, all held together with velcro and elastic bands..
I do have a casing which I will be trying out this weekend - but my 'ultimate lantern' is a little more complicated, since I want to include 2 LS w/o emitters for a low(!) light mode. I figure that with these RC packs I can probably get the better part of 10 hours run time for 2 LSes...
