single D cell torch?

ive been searching and nothing. we only have d cell batteries free at work, and the yellow plastic 2 cell lights they give are pitifu

 

anyone know of a good single D cell light?

IMO single D´s are quite rare, can´t think of any right now...

ElectoLumens used to make a 1D Blaster, I keep hoping that some day he would make another batch. There are peeps that can cut down maglites and thread them so there 1D but I’m not sure how well they run without a driver mod.

I’ve seen a plastic 1D light that’s also very sad plastic fella. Otherwise I’m stumped.

I’m glad I’m not the only flashlight collector out there, I was beginning to think I was strange.

Perhaps a sk68 a d cell cradle, some soldering and a bit of tape :bigsmile:
Would be very cheap….and is able to run on 1.5V with a d cell some hours….

I think I’d rather ask one of the people here to cut down a 2D maglite, down to 1D size Wink if I’m duct taping something together its not going to leave the work bench Wink

To find a host you could search after 32650 a D cell is 32600…

This is an possible example, description says its able to run from 0.9V so check it out… http://dx.com/p/saik-sa-305-cree-q2-wc-3-mode-140lm-white-led-flashlight...
But there are quite expensive diving lamps out there in this diameter, but I’ve not seen one which is capable of one D cell from stock.

So the thread starter should mention budget and if it should be DIY or not…

Well, for a cheap host here’s a pair for $5 from Amazon. Not stellar reviews on quality but a cheap priced host to mod maybe.

I have one, its almost all plastic they have an SMD led, a whopping 10 lumens. There almost 2D in length with a really large spring in the body so you can use 1D cell

This is from Amazon

Well, all of the flashlights have now been on for 55 hours without any apparent dimming of their lights.

You pointed out that they are 10 lumen, since they are so cheap and with two in a pack, they almost sound like a great black out gift for our relationships who we just cannot introduce to preparedness.

What do you think? Are they adequate enough for that?

Yeah, there adequet for that, but don’t leave alkaline batteries in a light for a year+ at a time. I bought mine from Rona, been using it as a battery vampire

I would like a C or D version of the Sipik sk68, that would be neat.

I would like to see someone come up with a Pak-lite led device to hook onto a D-battery, for longgggggggg term black out use as a tiny lantern.

Maglite really should introduce 1D and 1C models these days.

the problem being 1d or 1c either needs three smaller primaries ( aa or aaa) in series or one lithium 3.7v cell to really give decent output.

I take it by “decent” you mean maximum. Not sure why everyone is so obsessed with maximum output from their LED. Run time is important too.

that was the idea

that is basically what they give us at work. they are absolute junk. but on the other hand, i literally set one on fire about once a week on average probably haha.
the idea was something more durable, with higher output than a junk plastic incan. something i could keep near by to get a better look at my welds when im done
edit: but i dont get the cool reflector at work that those ones have :~
edit: i actually like the sounds of a d cell sk68… you could use Ds, or a 3aa parallel adapter with 14500s… or use a sleeve for a 25500 or they could make an adapter for 18350/16340…. you listening china?

I agree about runtime, but you’d get more runtime from 3-4 eneloops in series than 1 d cell, dont forget the circuit will have to boost to 3+ volts and it wont give much current to the emitter.

I just dont see it as a commercially viable solution myself.

A better solution all round would be a light that has a very good quality 3aa series battery carrier or the option of using a 26650 cell. If that was done, it would be a winner

Not if you used an 8000-10000mAh D cell.

that still wouldn’t work for the op, I highly doubt his work doles out 10000mah tenergies, or a charger that doesn’t take days to charge them.

And how many consumers will splurge $100 or so just on a few cells and a charger to run a torch? Eneloops are at least, pretty mainstream now, and, as I pointed out, no-one has elected to build such a light, there must be a reason, I suggest that reason is output vs size as I’ve not seen a single primary cell driver that does over 1a to the emitter.

Just because nobody has marketed one yet does not mean it wouldn’t be a success with good marketing behind it. Most companies tend to copy the latest trends and dont bring much new to the party.

I have one of these . Blueish , pencil beam with weak spill . I sputtered the reflector in an attempt to get more spill out of it . It didn't help much . Then I DC-Fixed the lens and now it has a tolerable beam profile .

It is a heavy , sturdily built light but I can't recommend it .

Depends on what you mean by ‘decent’. Most people would consider the 280 lumens from a Zebralight SC52 to be MORE than decent. And given the fact that both the capacity and maximum amperage of a D FAR exceeds that of a AA, you could get more than 280 lumens with more runtime from 1xD. Realistically, you could probably get 500 lumens for at least an hour from a 1xD light. Not too bad.

On the other hand, a 1xD light would probably be a fairly unruly affair. Diameter-wise, it certainly won’t fit as well in your hand as a light that uses smaller diameter batteries. And without the length to get a good balance (like, say, a full-sized Mag), it will be just plain tiring to carry. This would especially be true with something like a 1xD Mag, which would be quite head-heavy.

Without lamps, there’d be no light.

Batteries are not made for high current.
If you pull 2A from a D cell it lasts 2 hours until 0.8V are reached. Highly decreasing with more current.

So if you want to drive a LED with 1.5A and the LED has a forward voltage of 3.xV
1.5A*3V=4.5W …..would mean if you have batterie voltage of 1V you will need 4.5A…

So the only way would be to go with rechargeable nimh…and then you could easily just use 2 18650 which are not much bigger but better.

this light was not meant to be a heavy driven xml. just a moderately driven LED, under 100 lumens would have been sufficient.

it would have been attached to a swivel with a magnet attached to that to aim at the pieces i need to weld. d cell was what i wanted at the time because thats all they supplied us at the time. they now have aaa also.

gave up on a single d cell light. pretty much would need to have one custom made. i set about 1 flashlight on fire every week or so, and burn up 3 or so plastic lenses a week. just not feasible to spend money on a custom light to set on fire
