thanks for the charger info. I will call c crane tomorrow and visit RS before the weekend.

thanks for the confirm on this product.
One more question if I may.
Do you have any information on a charger that can be used to charge the battery packs used in the SF8AX or the Streamlight stinger.

I've been running NIMH's in my Tec40 with overdriven 3.6V .75 Amp Kryptons as suggested elsewhere in this string. They are available at Radio Shack and as the standard Ray-O-Vac 4 cell bulb at WalMart.
I've also been concerned about the long tips on many of the Halogen bulbs. (Read Alan's earlier comments.)
I've ordered some 1.7 Amp 4 rechargeable cell Krypton Carley bulbs. I'll probably use just in Mags if (a) they don't fit, (b)if the AA NIMH's can't handle the draw, or (c) I see reflector deformation.
Curiously Carley doesn't seem to go above .87 amps on Xenon bulbs with PR bases.)
More interestingly, for the Tec40, I've found and ordered the following bulbs at www.topbulb.com.
HPR44 Halogen 1.0 amp 4.0 volts for 4 rechargeables $2.57 @. Maybe it'll fit and maybe it won't
KPR139 Krypton 1.2 amp 3.85 volts for 4 rechargeables $1.41 @
Shipping on any order is a flat $5.95.
Unlike the Carley's, both of these unusual but standard bulbs probably are designed for prefocused reflectors.
The 1.2 amp Krypton bulb shouldn't present a lens interference problem.
The voltage drop on the NIMH's at a 1.2 AMP draw should mean the 3.85V bulb is much less overdriven than with the 3.6V .75 Amp bulb.
A 1.2 Amp Krypton bulb probably runs cooler than a comparable Halogen bulb. (Maybe that's why I haven't found a PR base halogen pumping out more than 1.0 Amps.)
Assuming that the 4AA NIMH's voltage reduce down to 4.0V with the 1.2 Kryptons. These lamps should run at roughly 4.8 Watts.
If I don't melt anything after these bulbs arrive, perhaps Brock would want to test this configuration.
In any event, have fun browsing the topbulb site.

Well, I tried to have fun there, but it didn't seem to want to open for me. Even typing in www.topbulb.com didn't work for me.

Yeah, the earlier link had a period in with it. However, clicking on my link is still giving me problems. It says "No data is available for the requested resource" or something. Oh well, I'll attempt to translate it from german to english, that should make it work (that is how you get around restricted websites, lol).

lemlux,
Where do you get your Carley bulbs? I've tried ordering from them directly, but they have a $50 minimum - too much for me to try out some bulbs.

I recently bought the last 4 Carley lamps with aperages between 1.3 and 1.7 that Tim Flanagan at Noreast Knives had.
As I was led to believe from this forum, Tims is a very helpful and frfiendly vendor. He's getting reqdy to reorder and would be happy to hear from you. His email (no website) is listed as a vendor link here and on Brock's website (Sorry, it's not on my home computer contact list).perages between 1.3 and 1.7 that Tim Flanagan at Noreast Knives had.

Sorry for the messy non-proofread last post. Today I received my lamp orders from both NorEast Knives and TopBulb.com.
I'm afraid to use my HPR44 4.0 V 1.0 Amp Halogen ($2.57 from Top Bulb) with the Tec40 and Nimh's because the Halogen nipple is too close to the lens. I think I'm pushing the extended run temperature limit with a KLPR139 3.85 V 1.20 Amp Krypton bulb ($1.41 from Top Bulb).
The PT40 generated considerably brighter output and a nice larger flood hot spot from a 3.7 V 1.70 Amp Carley Krypton Star ($5.00 from NorEast Knives in quantities of 2 or more) using 2 Carley focusing spacers. I was pleased to see that the Nimhs had no problem handling the amperage. Nonetheless, the generated heat combined with Alan's multiple cautionary PT40 heat vulnerability comments made me settle for the 3.85 V 1.20 Amp Krypton.

Gees. I didn't know you could get Krypton Star bulbs from someone other than Carley. I've been trying to get my hands on those for a while.
How close does the bulb tip come to the lens? With Whitestar it's close, and with KPR103 it's even closer. That's probably my greatest concern about heat. If the tip gets too close, it will burn a little dot in the lens.

I would guess that the Carleys extend approximately 3/32 less than a halogen bulb. They also come with washer spacers that allow you to set focus on a non-focusable light like the PT40.
The tip of the Carley is a perfect hemisphere that focuses some light straight ahead. They're the first bulbs I've used that actually fill in much of the black holein the center of Mags adjusted to flood useage.

voltage vrs amps
You could compare them to a garden water hose. How hard the water is comming out or pressure is the same as voltage. How much water is comming out or quantity is equal to amps. Hope this helps a little.

I previously tried filing an HPR nipple with a nail file. Nothing happened.
I next moved to medium sandpaper. Very quickly I had a slightly shorter nipple with a hole in the center. HPR nipples are hollow pretty close to the surface. (I didn't treat myself to viewing a bulb burnout at this point.)
Tim Flanagan can be reached by email at [email protected] You'll see his name frequently on this site and Craig's site has him listed in his links.

Been there and got same result. I should have posted this before you wasted one bulb
