Acebeam Pokelit 2AA vs Lumintop PK27

- Опубліковано 25 сер 2024
- Acebeam Pokelit 2AA has a Nichia 519A high CRI emitter and takes either two AA batteries or the included lithium cell. It produces a floody beam. Nealsgadgets sent this for review.
Lumintop PK27 has an Osram CSLNM1 emitter and takes either one or two AAA batteries. It produces a throwy beam. Lumintop sent this for free as a part of a giveaway.

Osram CSLNM1 is such an amazing LED for small lights. Throws really well and is a really nice pure white tint with hardly any tint shift in other flashlights I have with that LED. Might need to get a PK27!
Impressive throw for the lumintop!
Especially on disposable batteries! They are KNOWN for voltage sag under even minor current draw!
Wow! What a little thrower
Cool, thanks a bunch! The throw on the LT is just ridiculous! I have one coming, and I"ll probably toss a li-ion 10440 in place of the 2 aaa's. I can't find any information whether the extra .5 volts or not will be okay. I'd imagine lumintop wouldn't make disposable cell drivers only...but then again, O-light went ahead and did that very thing 4-5 years ago! I burned up a nice copper special edition 0-light with a 10440! It was seriously bright for that 5 minutes though. LOL
I posted a review on my website with some more info. A 10440 didn't immediately destroy the driver or LED. The beam had a hint of purple with 4.18 V so it's being pushed a bit too hard. I'd use a 10440 with caution but wouldn't recommend 😅
@@TorchHacker I sincerely appreciate the information. Yes, agree totally that if you're getting that purple tinge... Then it's most definitely at the limit. What I ended up doing was starting with a li-ion at about 60% charged... 3.8 volts or so and worked my way up. So far so good, but I'm not pushing the light long at 4+ volts.
The one thing I think Lumintop was banking on was pretty serious voltage sag with the AAA cells. I noticed a fairly large difference with single cell performance between an alkaline and ni-mh. I didn't bother to do tailcap readings, but figured it had to be the alkaline not keeping up with current demand and massive voltage sag as a result.
Long story short, I agree 4.2v seems to be at the ragged edge and asking for trouble...SO!What I've been doing is short charging the 10440's to about 4v and doing a few brief "turbo" blasts to settle the cell down and going with it. So far so good. Tint looks nice along with beam pattern and it seems to have a nice 200ish lumen bump from 2 alkaline AAAs. The throw is just ridiculous when you see the size of the light. LOL
You could try the LiFePo4 10440 battery. It is lower voltage due to the chemistry - 3.2v nominal, 3.7 when fully charged. They're relatively new and you need to have a charger which supports these batteries.
@@varbantopolov2641 Thanks for the suggestion, I am aware of the Iron Phosphate batteries. That's kind of what I'm trying to emulate by short charging the Li-Ion. I don't have a 10440 LiFePo4 on hand, and to be realistic, I don't want to purchase one because I would only use it in this application. I do have 14500 and 16340 LiFePo4's though so I'm familiar with them. Thanks again.
Just get the GT nano... if you want to use single cell lithiums.
It has more options and is brighter... you can use 3x AAA, 1x 10440, or 1x 10180
Nice review. Good job.
Thank you!
what extension tube? as far as I know it's only a single tube and no other option exists.
EDIT: I'll be damned... I had no idea the barrel was 2 pieces! I just ran over to my flashlight drawer and unscrewed mine... It's a shame the PK27 does not appear to do the same.
Pretty cool 1xAAA flashlight 😁
