The Princeton Tec Amps look nice
4 x AA Light?

They do. Unfortunately, they're flashlights, and in that regard, they are wholly unimpressive.

They don't have to be impressive if they can be fitted with a high-ouput aftermarket drop-in and high-performance AA cells.

Well, the Amps are Rebel 100 and the Amp 5 has a 5mm low mode, so what is there not to like? 70 lumen high is plenty useful and should run for a decent time

How about 2 Quark 2AA tape together.

Are there any 0.5 watt LED drop-in modules for the Underwater Kinetics eLED 4AA or 3AA?
I have the 4AAA version with the 4 5mm Nichias, the body itself is pretty nice, but the switch turns on way too easily, can't lockout and you have to hold it for like 3 seconds to turn it off. I believe someone on here had the AMP 5 and they returned it because it's Rebel beam quality wise sucked.
You realize it's a plastic host and won't be able to dissipate any heat? (It could make a good battery roaster!)
It might (I haven't taken measurements) be possible to make an adapter that would accept a standard drop-in, but the development time required to design and build it (the adapter would need to include the switch) would be better spent IMO designing a dedicated P60 host from scratch.
If you're really dying to try converting a plastic 4AA light to accept a standard drop-in, I'd start with the ProPoly Luxeon - not only does it look possible, if you or someone you know can machine delrin, it might even be easy. You'd still have the heat issue though.
Both beams are ugly to the point of distracting. The beam profile from the 3x 5mm's doesn't vary enough from the primary beam to justify the 5mm array (should have just given the primary LED two levels). And the 5mm beam is the typical, ugly cool temp.
Probably me - I've bitched about this light a few times. I never return lights, unless their defective, but I was tempted with the Amp 5.0.

Could you describe what makes the Amp 5's beam "ugly" in more detail? As it is one of the most modern 4AA lights, I am somewhat curious about it.
Also, the UK 4AA eLED Zoom seems to have a modern emitter if its claim of 77 lumens is correct. I have been pretty happy with the build quality of UK lights, seems this one is worth looking into.

Point well-taken; with a plastic body, you're left with only LED options. But for most of us, that's OK. Even for me, a onetime hotwire. In my recent test, three NiMH AA cells and three NiZn AA cells couldn't power a Lumens Factory high-output lamps to respectable levels. See my results, with beamshots.
The Pelican Little Ed and Stealthlite, both 84 lumens, however they are recoil LED's with tight beams. Oh and there's Gerber's Cree'd Carnivore (XP?) which is an angle head light with a main beam and a secondary beam with red and blue 5mm LED's for blood tracking if you're into that kind of thing.
How about 2 Quark 2AA tape together.
This is a pretty good idea! a little foam between them and zipties to secure them. I might do this! thanks for the idea!:twothumbs

I'd buy a light like the Fenix TK-40 but make it a short stubby 4AA light so that it looks like the Dorcy Solid state that someone posted a pic of on page one of this thread. So keep it thick like the TK-40, but a couple of inches shorter because it's only 4AA.
But instead of the Dorcy, have it be a decent quality light with a metal body for around $100.
How about Fenix making it and calling it the "One Half TK-40"? Use the same head as the TK-40 but eliminate the turbo mode because 4AA batteries can't handle it. Instead just have the low, med, high of the TK-40.
Yeah, I'd buy that.

I just found the UK 4AA eLed zoom comes also in right-angle flavoursand orange too! 🙄
That head is rotate-able too. It has a 2 stage switch for hi-low (see Brightguy for more info - it comes on hi first). It also is regulated, and will power down if it gets too warm according to the UK home site.
That clip could be trimmed, placed at the end, and possibly used for tail-standing. The 4AA model is a bit tall for tail-standing stability. The newest version, called the 3AA eLED CPO is much shorter and probably more stable for tail-standing. The 3AA version does not have a 2 stage switch though. I was told all of these models with rounded edges will not tail stand without some help of some kind.
Does anyone on CPF know how to do a mod to decrease the power consumption on these UK eLED modules and increase runtime?

The primary beam has decent flood, but the hot spot looks like someone put their thumb in it - uneven with lots of artifacts in it. I find it pretty distracting, and I'm not sure how they managed to do that with a Rebel + smooth reflector combo. The 3x 5mm beam is awful - blue, lots of artifacts and reflections from the offset emitter positions, and it's surprisingly concentrated for 5mm's. And, again, unless there's a ridiculous improvement in efficiency from the 5mm array over the primary LED, I don't understand the point of the latter. The profiles of the two beams just aren't significantly different - certainly not enough to justify the added complexity.
When I first read about the light, I was hoping for a LunaSol for the masses, and with a little surgery, it might be that. But it looks like someone had the right idea when they designed it, but someone else was responsible for selecting the LEDs, and the latter was either hamstrung or didn't care (or maybe blind).
The host itself isn't too bad. It's not as comfortable to hold as the ProPoly (little too wide, IMO), but the switch is in a better position, and it looks like it might have decent water resistance. The tactile feel of the switch is pretty awful, though.

Four Eneloop AA batteries work just fine in my TK40 when I operate it in turbo mode. High quality batteries are a must though, but not like anyone around CPF is devoted to leaky alkaline batteries anyway.
