Lamp for 10 1/2 D Mag

I have a 6 cell MAG with the carley reflector, and 10 1/2 D's. I can not find the proper lamp for this configuration.
It blew a 7 cell Mag lamp I had ordered from Flashligking.com. Does anyone have a suggestion? I can use Bi-pins or PR based lamps.

Max,

Thats going to take one of the 9.6, 10.5 or 12 volt Welch Allyn bulbs, I don't know if the 9.6 will take that much overdrive, but you can see if the 01126, 01149, or 01154 would work.

You also could try the 01185, driven at 12 volts it is INCREDIBLY bright (somewhere above 1000 lumens) but they have been known to instaflash at that rate. I drive mine with 9 NiMH AA cells in a 3D mag and it is by far the brightest light I own. It's rated for 9.6 volts.

Carley also makes bulbs that will work, both have websites.

Try walamp.com and carleylamps.com.

The most commonly used Carleys would be the 808 and 809, there might be a few others if you look hard.

The 12 volt bulbs will actually be a little underdriven as the voltage drops, but will then last a lot longer.

Good Luck!!

The WA01185 is very bright but I don't think it will survive 10 x 1/2D cells even though it only has a 30% instaflash rate on 10 x AA. The reason is the less severe voltage drop with the more robust 1/2D cells. I'd estimate a difference of about 0.05V/cell or 0.5V total for a stack of 10. The Carley 809 would be a better bet for extreme overdrive.

Alternatively, the WA01312 would be a decent choice for driving it at spec. And it'd still be pretty bright.

Any 12V lamp would be suitable. Just pick a bright one as the overdrive will start out modest and quickly drop to zero and then into underdrive as the run wears on.

Here's something that might be fun to try, since you have bi-pin capability. Many of the cheaper automotive bulbs (like H3 or H1 made in China or somewhere else in the far east) are actually caged G4 bipin bulbs. This means that if you peel away the support cage with some pliers, you'll find a 4mm bipin bulb (like the Carley and Welch Allyn units). Just snip away the welded leads, trim the pins a bit and away you go. The bulbs will be quite large, so you will have to open up the hole in the reflector.

The better quality bulbs will use GY4(?) with 1mm thick pins spaced 4mm apart. These will be too thick to insert into a Carley CL912 bipin to PR base adapter. However, the cheapies with the G4 (0.7mm pins spaced 4mm apart) will work just fine.

I think these bulbs are in the range of 55 watts or higher. This power level will rapidly destroy whatever adapter you intend to use (unless it is ceramic based) but it sure will be bright for as long as it runs. At 55W, you'll be pulling a very healthy 4.6 amps.

Have some fun and if you do try this, please come back and let us know how it turns out.

WA1166 will be good choice too if you don't want to go with HID

Ginseng, you said that the Carley 809 is the best bet for extreme overdrive.
That means it will work well on a Mag Lite 4 "C" with FIVE
123 batteries?
I am going to get two potted 809 and I will like to try them in that configuration if they can be overdrive that much.
Thank you
Juan C.

The 809 has worked fine for me on 5x123. In fact, I use that bulb to bleed voltage off the pack before I put in my WA01318.

Wilkey

Ginseng, thank you for answering, I would put the Carley 809 in a Mag-Lite 4 "C" with FIVE Surefire 123's and the WA01318 in an identical flashlight but with the 4 1/2 configuration (4-123's plus a lithium AA.

Which flashlight will be brigther?
Why so many mentions of the WA01318 but almost none of the Carley 809?
thank you for "enlighten" us Ginseng.

Juan C.

The WA01318 will crush the 809. The 809 is expensive and compared to the related WelchAllyn bulbs, are not as bright. On the plus side, it has a decent current draw that allows it to work well with 123 cells.

Always glad to help out. /ubbthreads/images/graemlins/smile.gif

Wilky, what do you think about WA1154 plus an additional battery?

Varooj,
I've no experience with the 1154 but by the specs, it looks terrific for 11-cell overdrive. Plenty of life, good efficacy, up to 1,000 lumens. The only issue I have is that it's a lensed end bulb. I typically don't like lens end for the filament image they cast.
Wilkey

Try the 1166. I am using them much more than the WA185 or CL808/809 right now. 10 1/2Ds should drive it just about right. If it's fully driven it is VERY bright.

Finally, I tested WA1154 using 10 cells of 1/2D, Not bright.
11 cells of 1/2D, Not bad.
12 cells of 1/2D, bright.
13 cells of 1/2D, OMG !!!

Now THAT'S overdrive! /ubbthreads/images/graemlins/grin.gif

fivemega what mean "omg"?

the 1154 bulb have 4mm of filament... how you can tight the spot?

OMG means Oh My God /ubbthreads/images/graemlins/smile.gif

That's bad part of this bulb.

Beam is not very tight and almost shape of stock MC bulb (oval).
