I know the legacy around here is to kind of just search through old threads, but when poking around about incandescent lights...my word...the threads are CRAZY old.
Some of the companies discussed have been out of business so long, that a kid born when they disappeared could drive you to the bar, and maybe have a beer with you, hahaha.

So, maybe let's share what's still alive and kicking, or at least readily available as we're nearing the end of 2025, into 2026.

I'm in the camp of "When these were all around, they were kind of expensive, so I wasn't really interested." Now, I'm older, have more disposable income, and think they're just neat, and have pretty beams. The nostalgia is fun, too. BUT, that means I don't have a draw full of old adapters and parts. I'm incandescent curious, but a bit dismayed at the landscape these days. But, I'll plead complete ignorance, so maybe I'm just missing obvious things.


From what I've found, it seems like the incandescent modding world is mostly dead. Many people still have old stuff from back when, and might use that, but it's not really an active market.

Maglite still makes and sells incandescent lights, and they still have the normal Maglite quirks (for better and worse).

The P60 ecosystem seems to be maybe the best bet these days. Both Kaidomain and Lumens Factory sell parts and drop-ins (Lumens Factory sells a decent range, even).
Malkoff and Lumencraft sell some adapters for running Li-ion cells in a Maglite, but are more focused on LED conversions.
MHVAST can be found if you want a 3P clone (with a glass lens), or parts (I find them to be more expensive than Lumens Factory, and less nice, though).
Sure, new-old-stock and used Surefire hosts are around, but the prices are kind of nuts.
Surefire DOES seem to sell 65 lumen P60 drop-ins, still (but they say you can't use LFP batteries?).

I know people used to run all sorts of different bulbs, especially in Maglites, and that stuff looks awesome, but it seems like that's all with adapters no longer available. Is anyone still making this stuff?
There appears to be some availability for the more "hot rod" bulbs, but without the adapters, it's not as useful for someone looking to explore this.

Regarding voltages, LiFePO4 seems to be great with incandescents because of the voltage ranges, BUT ALSO because of the flat discharge curve. There are a LOT less LFP batteries around in "conventional" Li-ion sizes these days, though. But, you can still get RCR123 (16340), 18650, 10440, 14500, 18350 sized LFP cells.

From what I gather, the advantage of higher voltage drop-ins is less draw, so longer runtimes, but it does seem like the incandescent drop-ins still being made are meant more for normal Li-ion voltages (which is probably a good thing) - save for the warning on the Surefire ones (which is a 6V drop-in).

So, is this kind of it?
Anything I'm missing?
Any "hidden gems" still out there?
 
Well, since you asked, in my opinion, upgrading incans to LED is not financially feasable today, as you can buy a new LED flashlight of equal or better brightness for less than the cost to upgrade an incan.

Now, upgrading an incan to a fire-breathing hotwire, I can understand, for CME/EMP preparedness. One second after, the incans may be the ruling big dogs, and having a few fire-breathers could come in really, really handy. Of course, keeping them running will be the trick, as power generation will be tricky.
 
Sure, I'm talking more about the latter. A lot of the older posts are centered around the former, and for someone today looking to play with incans, the options are a lot more limited, and a LOT of the stuff mentioned in older posts is from (now) non-existent companies.

I'm not even talking about this for any practical purpose. I just think it's fun, and incandescent lights make for a pretty, albeit hot, beam, haha. But, a lot of the stuff people seem to bring up is stuff that they may have purchased 20-25+ years ago. Which, if you don't own that, you kind of can't get.

Essentially, I'm just curious about, if you missed the incandescent halcyon days, are you just completely up the creek? Or, are there companies still churning out low numbers of their niche products for nerds, haha.

I'm okay if the answer is essentially, "Buy a high output drop-in from Lumens Factory," and that's about the most "hot rod" you can still put together today.


@swampgator had very graciously steered me to the Incandescent "Threads of Interest," but it also seems like a lot of the stuff in them in no longer available.

And, maybe I'm just not aware of some of the places people still source parts, etc.
I've seen people mentioning random garage/flea market sales, but that's not super reliable, haha.
 
Well, for glass lenses there's still flashlightlens.com. Maglite.com sells some glass and plastic lenses for their lights, but no details on the materials. Litt Industries sells some lenses, too, for Maglites.

For metal reflectors I think kaidomain.com still sells them, but they are in the PRC, so you would be feeding the beast, plus likely paying an import tariff. Other than them, I don't know of a metal reflector source. There may be some members who still have hotwire parts that they would sell, so an ad in the b/s/t section for hotwire parts might be productive.

Some of the bulbs are no longer available, but if you do a search, you can still find bulb dealers. But you need to know what bulbs to buy, so you will have to really do your homework to figure it out.

Batteries shouldn't be a problem, in fact, there are probably more options today, with better mah, than the oldtimers had access to. Plus, you can make or buy spacers for the lithium and nimh cells.

Hosts shouldn't be a problem, either. There were millions of Maglites made and sold, so ebay, thrift stores, yard sales, and auctions should yield tons of host Maglites for really cheap prices. If you want new, Maglite still sells brand new incans on their website maglite.com under the Classic heading. They still sell the bi-pin lamps for them, too. Do not buy lamps off the big river site! They are marked up super high. In fact, I would warn you to be very careful of ordering Maglite products off that site. I was on there earlier today looking at the Maglite products, and a lot of it was over-priced compared to maglite.com.
You could try to upgrade some other incans, but I think you might want to start with Maglite--there are just so many more parts available for them compared to other brands and models. Once you get the hang of it, then you might want to hotwire an EverReady Commander or a Ray-O-Vac Sportsman, SureFire or whatever.
 
you can build entire lights at lumens factory.
I do not suggest "upgrading" to led. That's always been dumb and time hasn't made the idea better.
Why are you so stuck on lfp? They usually don't match any voltages except for custom bulbs
You could buy a 3c maglite, kaidomain has aluminum reflectors and glass lenses. 2x 21700 in a sleeve you can make yourself. A 6 cell maglite bulb or this, https://ebay.us/m/23eNj4, for 200 lumens and 5-6h runtime. Or one of them for 320 lumens for 3.5h https://ebay.us/m/veGJWz
 
Cool beans. I did grab a few new incandescent Maglites to use as a host, and got the OP reflector from Kaidomain (with some incan drop-ins for the Surefire ecosystem) because...yeah...no one is making those, otherwise. It's always interesting how Chinese companies will churn stuff out so much longer after stuff had died off over here.

So, the funny thing it, I kind of got into incans because I wanted something that would run LFP, haha.
LFP is just a really cool battery technology. I'm an Eneloop diehard, and the extreme safety, recharge cycles, and ability to be generally abused means that LFP really strikes my fancy, haha. LFP is pretty hard to use with most LED lights, as they tend to either use NiMH or Li-ion voltages. Though, LFP seems to be good-to-go with Peaks, which REALLY excites me (I love Peak lights). And also, due to the fact LFP is a bit older of chemistry, they seem to better match with the older voltage ranges of incan lights (3V, 6V, 9V), which were running disposable CR123A cells.

No lfp cells don't match cr123 cells. You'll pop the bulbs if you try that. Now 3 cr123 and 2x lithium ion is almost a perfect match
Lfp is a good chemistry. And I wish they were better. But they have roughly half the wh of the same NMC cell, and can handle less current.

Maybe that is because they are just as concerned about a CME/EMP as we are, and are stockpiling incans, just in case. 😉
 
I think only you are worried about that solman.

Well fine I'm sure there are some others who think the moon landings were faked would worry about this😋

I assumed that's what Surefire was talking about, since two LFP's would be a good margin over 6V. The Kaidomain and Lumens Factory drop-ins seem to come in 3.7V or 9V variety, and running two Li-ions in the 9V has been just fine.

I do think there's something fun about an 1800mAh LFP 18650 running something ~3V, though, ahha.

Good call about the current, I'll have to keep that in mind if I can find any of the adapters that let Maglites run more zesty bulbs.

China went all-in on LFP, so all the production is there because no one can come close to competing, so I'm still waiting for a set of RCR123 cells to arrive, so I can play around with them. I still need to probably ask Gene if an M31 can run on one. That could be nice option for the 3P clone host I have.

I think if you're super concerned, there's been some interesting stuff done with Faraday bags and boxes, than seem to insulate enclosed electronics.
Sometimes I think I should put together a faraday bag, and put some backup stuff in an ammo can...you know...just in case.

Rather have it and not need it, than need it and not have it 😉

A cr123a under load is around 2.4v. An lfp cell is 3.2v. So a p60 is a 4.8v bulb. Feeding it 6.4v, it's not going to last long. A p61 is even worse as a 4.4v bulb.

Companies like BYD and their blade lfp batteries are getting good. But we're not getting that in our cylindrical cells.

So if you want to use lfp cells, you need to look at 3.2, 6.4, 9.6, etc volt bulbs. Tads customs had some bulbs specifically for lfp cells, but those were custom bulbs and not available anymore.

They work well as a replacement for led lights because those have buck circuits. Within reason they don't care about incoming voltage, as long as it's not over their max design. But incans are direct drive
 
If you're dead set on Incan hotwires in 2025, I'd get a hold of fivemega for some items
Get a 4D Mag, bore it out with a brake hone so it will fit his 16 AA to 4 D adapters.
A 12 AA to 3D would better but he's sold out.
Then get one of his G 6.35 bi pin to PR bulb adapters.
Get an aluminum reflector and glass lens.
Run an Osram 62138 HLX bulb on 12 Eneloops and 4 dummy cells. It's 2800 lumens on 12 volts.

A smaller form factor would be a Philips 5761 in a 2C Mag. But finding a G4 to bi pin adapter may prove a challenge.
You could go with a 2D Mag using his adapter mentioned above.

Ooooh, that sounds fun. I have his MD1 and MD1.5, and I quite like them. I'll have to poke around his threads. I think he still has a 18350 host body I was interested in grabbing, too.
 
There's also his prince series. Those are very nice. He also makes a 2x and 3x 18500 d36 light. Similar to a lf seraph p9 with the mini turbo head. But higher quality. And those have bulbs still available as the lf D36 assemblies. These are very nice bulbs/reflectors
