UPDATE! groupbuy: Lumintop EDC05C - first 100 pcs only US$29.99

If this can charge AA battery, it is the very first usb rechargeable AA flashlight I’ve seen :+1:

From BG’s page:
“*2) To avoid the risk of exposition, it’s forbidden to charge the AA (Ni-MH/ Alkaline) directly via the flashlight.”

It can be designed a few different ways. One way is it detects if the voltage is about 2.3v or higher. If so, it will charge to 4.2 with a lithium charge curve (CC/CV).
If below 2.3, it charges with a NiMh charge curve to 1.5v.

The other option is that it does not charge at all if the voltage is below 2.3v (roughly). This would prevent accidentally charging a AA alkaline battery.

Or perhaps we have to use our own judgment to not use the usb charging when there is a AA battery inside.

Another situation is that it may not even work with AA. It might be 14500 only.

Not sure about this one. 500 lumens is ok for EDC but the XP-L HD is capable of so much more. Wish it were in the 800-1000 lumen area. Not much on the built in battery. I have so many, I would like to be able to change them out. Think it would be great for a gift. Looks cool though.

can one have the front and side light on simultaneously?

Lumintop confirmed they use a xhp35

cell is of course user exchangeable

AA and NiMh and 14500

No.

That doesn’t make much sense. A 14500 battery can not supply the amps needed to run the xhp35 at any decent output (higher output than an xpl). Are they running it at 500 lumen (2.5A-3A at the battery) to get better efficiency compared to an xpl/xpl-hi?

I guess they are using a boost driver anyway so why not ramp the voltage up. If so, the 4 Nichia might even be wired in series for 12v as well.

The output must be really low when using a AA.

IDK, the whole design sounds a bit strange. I’m curious to learn more about it’s driver.

me too.

price: US$ 29.99 for the first 100 orders

(then price raises to 35.99)

This light with a double tail click (1 for the front led, another for the side led) would be nice!
Not saying it is not right now, but it would be nice in a different way (for me).
I’m with others, the 500 lumens on a XHP35-HI… :neutral_face:

hopefully there is a senseresistor... ;)

Ordered !

Thanks

Now on banggood says:
“Main Light: XHP35 HI, Cool White
Side Light: 4x Nichia NCSLE17, Natural White”

Is that a tritium vial slot in the tail?

That’s how you loosen the battery cover.

EDIT:Is just a notch to unscrew the tail.

From Tom E

It's a clever idea. I've decided I don't like 219Cs or 14500 lights, though. Another near-miss from Lumintop, for me. I want to like their lights so much, but I've yet to find the right one.

I do question the O-light aesthetics - while it's not a bad look, it's someone else's look.

It’s ok, they already did it with their ODF30C, which is basically an Olight R50… and nobody really complained so why not ?
YEs it’s a rant. No I’m not an Olight fanboy, I just hate when designers are lazy

I think you are overreacting with olight. What’s so common between ODF30C and R50? Blue bezel and button retaining ring? Fins on head, different, no flat part on head’s “bottom”. Flats vs fins around button. USB location different. Tail cap different. Checkering different. It’s still a tube with wider head and some fins. There’s just a limited variations how you can make it.
