Looking for the impossible….

@ZoomieFan Have you looked at the Acebeam Pokelite AA in Copper? The copper is running the 519a 5000K emitter (instead of the 219F in the aluminum ones) , High CRI, No extreme center hot spot (Just a well defined circle), Accepts both aa and any 14500, and no parasitic drain! I think this one checks all the boxes for you!

Does that mean that turbo’s on both light can be configured away or hidden.
If so, then turbo no longer is an issue

Yes. Set it to no TURBO, only ceiling

Isn’t the Skilhunt E2A pretty much perfect?

+1. This really does seem like what OP is looking for (stock without having to modify). Very under rated light IMO.

I really like the physical design of the E2A. It’s one of the smallest tail clicky AA lights I’ve seen, it feels good in the hand, and the beam profile is perfect for my use. But for a couple reasons, I decided not to recommend it. I reference Zeroair’s review even though he does not have a solid calibration source because his method is consistent, and his measurements end up similar to those made by others (1lumen also tested this light):

  1. It’s not actually floody. Personally, I think the pebbled TIR they use is the best feature of the E2A. It makes an even hotspot with a smooth fade, but minimal spill that looks just about perfect as an EDC-type light. However, it’s a general purpose beam, rather than a floody one. Zeroair measured about 10 candela/lumen. I would generally describe beams of less than 5 candela/lumen as floody, although there’s no strict limit.

  2. It doesn’t meet the claimed specs. Zeroair measured 300 lumens on 14500 for the high CRI. That suggests the low CRI version would probably get around 400 lumens, and the SST-20 isn’t known for good tint in its low CRI versions.

  3. Part of the reason it doesn’t meet its specs is because it is not very efficient. Based on Zeroair’s measurements, it’s performance on lithium ion is comparable to simple PWM linear drivers, and it’s performance on AA is even lower. This surprises me in part because Skilhunt can make good drivers. The M150 performance looks great.

For the use I bought the E2A for, high efficiency wasn’t critical, and I like the physical design well enough to overlook it. Since ZoomieFan wants 14500 support for the increased energy density, the Skilhunt’s relatively low efficiency doesn’t seem like a great fit.

So my first recommendation remains to try a floody TIR in the Tool AA they already have.

With all that said, if they want to try another light and see if the runtime and beam width are acceptable for their needs, I really do like the ergonomics, compact size, and smooth beam of the E2A.

If you’re using the normal ramping brightness you won’t get it to go as high as turbo. You need to double click to turn turbo on. (At least that’s how mine are set up.)

I thought you were looking for an honest politician when I read the thread title :slight_smile:

Getting close here!
Their site isn’t listing the specs. Or I’m overlooking them…
Can’t find the color temp. According to the specsheet of the led it comes in 2700, 3000, 3500, 4000K
Halfway the page is a picture showing the benefits of high CRI, but it shows 85+ while when I Google the specs of the led I find 95

Anyway getting somewhere…

I’m too old for such dreams :rofl:

300, and even 400 are far from the claimed 600.
Where does the difference come from I wonder.
If the driver just gives less juice and therefore the lumen go down but the runtime goes up, it might be acceptable.
But if all those lumens are wasted on inefficiency, that would be bad.

Could it be that the claimed 600 is measured without any optics, lens etc?
I have their H04 RC headlamp nice overall light and hard to make the following claim: When that small lens door is closed the light is more floody as I want it to be, but it also seems some lumens get lost in that plastic.

It may be overrated, but also note that 600lm is going to be at the coldest CCT, and in general warmer temps and high CRI come at the expense of sheer output/efficiency. The E2A comes in 6000k, 5000k and 4000k, with only the 4000k being 95CRI, being the one tested.

There is a lot off room in testing
they measure with effients LED, non high CRI, 6000k
they measure a prototype and the production LED is different, another batch. Or you can cerry pick a LED for testing.
Use the best battery, not the included.

Direct fresh of the charger.
flexibility with 30sec from turn on.

When you are in production you get suddenly less good parts from the supplier.
Or you use a substitute part.
Optic gets a slightly thicker coating …

Luminous Efficacy: typ. 130 lm/W @ 350 mA, 85°C (3000K)
Is from the specsheet. Can’t find any other lm/W but would be nice to compare them because then we know how much efficiency is lost in the led or in the light itself.

It’s going to vary bin to bin anyways, but you can find tests of a 4000k 95CRI SST-20 and a bin of 6500k 70 CRI SST-20 here on the forum.

At the same 1.4A, that bin of a 6500k emitter output 581lm , while the 4000k one outputs 406lm.

That’s naked emitters with a variance of nearly 200lm due to the CCT. Throw it in a light with optics and the ~300 range isn’t too far off, despite the 600 claimed LED lumens.

Seems to be a real science figuring out brightness.
Without a decent runtime test runtimes are a mystery too. 3 hours @2000lm turns out to be a sharp stepdown after 10 seconds and then slowly fadinding to ANSI lumens or something like that.

There are “only a few” things to consider when you look at runtime curves:

  • do they use the best in class battery or what came with the light?
  • is the battery fresh from the charger or had it rested for an hour?
  • when you use the included battery do you get its full capacity after a few charging cycles?
  • do you cool the light while testing?
  • is the LED the same? Normally the tested prototype is a different batch / bin then production. And while production they had to use different bins.
  • coatings on lenses can change
  • what temperature limit is set in Andúril? 45°C , 55°C or 60°C ?
  • can you have a different driver in the lamp, what is in your lamp?
  • was there a firmware update which changed the ramp? (e.g. TS10)
  • Can you use different battery tube? (A short tube is standard on a TS11 , sometimes runtimes and output are measured with a 30Q)

Short: it is a complete mess!
You are better of, when you run a test with the ceiling bounce app on your phone.

Thanks for making the impossible even more impossible! :slightly_smiling_face:

But yeah you are abolsutely right.
Add to the list, capacity of the cell and ambient temp.

Runtime tests can only be done after I bought the light.

Is there a ceiling bounce app?

for Android yes, don’t know for Apple

Reylight Pineapple or LAN?

SkyLumen has the Lumintop EDC15 modded to 519a 4500K 90CRI LED or 519a 3000K 90CRI LED. I have one of these, took less than 2 weeks to get and its only $30. It is very floody ( although not as floody as a mule, I prefer the less floody DC-fix over a reflector, myself) and the head will fit the tool body perfectly if you want it as a clicky. The tool clicky has a stupid blue led in the switch that probably has parasitic drain though. I think it’s pretty easy to remove.
