Review Acebeam L16 /// XHP35 HI 2000 Lumens

Nice review!!

I can’t stop asking myself why you run the light at 1000lm for 138min but the manufacturer only claims 1.2 hours at that mode

I don’t think the run times were listed quiet right………

I mean they have High listed at 1.2 hours at 1000 lumens and Turbo listed at 1.1 hours at 2000 lumens ……. Definitely something don’t compute right with that equation.

I actually have another light of a different brand , I am working on a review of now and it list 2.5 hours of run time with included cell in High mode………it went to 221 minutes , or about an hour over what is listed on it also ……Scratching my head over these long times for sure.

But manufacturer lists 500lumens for about 2.2 hours which are more or less your 138min on high (1000lm). Are you sure that the light didn’t stepdown from 1000 to 500 at some point? I’ll be buying one of this lights thanks for your review!

I will be gone a lot of the day today , but I will do another run time test later this evening just to double check the times and lumens.

OK everyone my sincere apologies for my initial report on the run time in High mode…….

I am glad now that Anthon kept insisting the numbers sound wrong for my run time test…….

I was going to be gone today but the plans that were in place have changed first thing this morning so I decided to try the test again.

I am going to be conducting 2 or 3 more run time test after this but for the moment the numbers as far as the run time is wayyyyyyy off from my first test. I pulled the chart for the initial testing from the OP , until I can get more concrete numbers and I will update again after all the test are done.

For now the run time only made it to 43 minutes , but the lumens readings stayed almost identical up to that point of the test.
The low voltage warning also flashed much sooner than in the first test I did. This time the warning blink came with the cell at 3.29 volts , the first test the cell was at 3.06 volts……the lumens at the end of the test today were at 1031 and the first test the lumens were at 993.
There are some things that are making me raise an eyebrow now……….
So there will no doubt be more testing going on with the included cell plus a couple of others and I will post results soon for my findings.

EDIT: OK I am confused now………I used the same online stop watch for all my testing , (my initial testing and the test I have done today)
I get the same lumens readings (or within 8 to 12 lumens) with the provided Acebeam 3100 mAh cell , the LG HG2 3000 mAH high drain and the Efest purple 3000 mAh high drain………all the run times are within 1 to 2 minutes of each other with an average of 43 to 45 minutes with the light on High mode.

EDIT #2……I also meant to mention the Low Voltage warning (blink) is occurring at 3.2 or above with all three of the cells I tried so far in these later test , so all of them are indicating at a higher percentage of capacity remaining than what the initial test showed which was 3.06.

HOW did I get what I did the first time using the same tools and the same online stop watch that was used for these test?
I DONT HAVE A CLUE.

Again I apologize for the first testing I did and put in my review. I am always very diligent and careful to make sure I do everything the same each time to assure accurate results.
I will be even more careful in the future as I really feel bad about posting inaccuarate results in this review.

Thanks for running the test again, now the runtime sounds more accordingly. However I wonder how did acebeam rate the runtime at 80 minutes when in reality it only runs for 45, maybe they’re counting the runtime after the drop?

I knew it was impossible for a 11Wh cell to put out 1,000lm for 2 hours, even if the driver was 100% efficient. As a general rule to calculate runtime: a high capacity 18650 should be able to produce 1,000lm for 1hour in a modern flashlight.

I always enjoy your video reviews. Keep up the good work.

Too bad we don’t get discounts with acebeam

Cheapest I could find was from Andrew-Amanda. MAP still applies but you get the option to submit your offer and get the lowest possible price.

im considering ordering one , any negative comments since the last post why i should not get one ?

So far I really don’t have any negatives about the light at all.

thank you

I wish acebeam L16 would came in 26650 format., please. This L16 is a 2000 lumen light, and 26650 would fit perfect in this light. We can use turbo for long time.

you have the EC60, it’s the same head, led and reflector as the L16

Any idea of what the turbo current is on the L16? This might sound crazy, but I want to mod it to a quad XHP35 HI 4000K 80CRI with Angie-S optics. I want a more floody beam.

If I know the turbo current I can calculate the lumen output from a quad XHP35 HI.

All of my measurements are in the charts in the OP.

I saw that, thank you. But how does that accurately convert to the 12V side factoring in the efficiency of the driver? It can easily be the 1.4A vs 1.7A which makes a big difference on the XHP35.

I am getting 1.54 at the emitter at start.

Thank you!

L30 and L16 has lego battery tube.

Original one;

With changed battery tube. L30 with 18650, L16 with 21700, 5100mA.
