Thanks for the review. I tested the white one and the driver bug was not present in my sample. I did notice the very high external temperatures thoough- up to 65 C so the led is driven really hard. The included USB cable is a surprise! I noticed it’s very high quality. I did measure the throw and output and it’s less than Acebeams 802 m at 694 m at 30 sec. (716 m at 5 sec) but that’s remarkable for a sub-40 mm head and no reflector. I think TIR is the future of flashlights, and with the Boost HX 2mm2 version pushing 1500 lm and 200cd 2mm surface brightness at 6A I’d be surprised if Acebeam doesn’t upgrade to this emitter in the future. Downside is its expensive…more than a xhp50.2 3v.
Very good beam shots and comparisons thanks. Looks like I got the last green one at battery junction.
The red beam on the Amutorch New VG10 looks really strong, do you think it might be brighter than the L17 with red?
That‘s a good question. I did some researching...
Acebeam rated their red L17 with a maximum output of 300lm using Osram‘s Ostar Projection Compact KR CSLNM1.23. Concerning the Amutorch New VG10 Neil Zhang did not state any output on his website except for a red „20W Osram“ LED.
The only red Osram emitter that seemed to be available by the time I bought it was the before mentioned LE R Q8WP which seems to be a close relative to the white Osram Oslon Boost HX with 4040 footprint. A tailcap bypass measurement revealed approx. 5A of current on high mode.
Now, let’s have a look at some numbers...
LE R Q8WP is rated with up to 224lm at 1,400mA forward current. The LED can be driven up to 5,000mA.
KR CSLNM1.23 is rated with 180lm at 1,000mA forward current. The LED can be driven up to 2,500mA.
Acebeam probably runs the red emitter in their L17 at 2,000mA forward current to get approx. 300lm. If Amutorch‘s New VG10 puts 5,000mA on their emitter it should theoretically yield about 700lm of red light. The radiation surface of KR CSLNM1.23 is only 1mm² which makes it ideal for a small sized thrower. Sizewise LE R Q8WP can be compared with White Flat 2 or Boost HX using 2mm².
Please note that this is more or less an assumption instead of hard, proven facts. ;-)
I think those assumptions are pretty good and way more than I would have figured out. nìce job! I'm really tempted to get the amutorch red just as I promised myself to get only two lights a year that are unique from now on
Thank you klrman. I guess the LED in Amutorch‘s New VG10 can be compared with the white „White Flat 2“ while the LED in Acebeam‘s red L17 can be compared with the white „White Flat 1“.
I wonder if Acebeam is interested in using the bigger but more powerful red version in their L17, too. I guess it’s difficult to source Osram‘s LE R Q8WP as I did not find it anywhere to buy (Mouser, Arrow, Digikey).
Please check with Martin before you order the Amutorch from Neill. He may offer you a nice discount. And be careful with the high mode as the light gets warm very quickly. ;-) You will probably feel most comfortable using the medium mode which looks almost as bright as the high mode but with less excess heat.
Interested in some comparisons to the E10
Seems to throw a bit further?
well done
Acebeam informed me that L17 does support momentary mode using an optional remote switch (which was not supplied with the light). I have revised my review accordingly. I still would have favored a momentary mode being available in the flashlight's standard tailcap.
Not sure what this Acebeam will do that my $18 Convoy can’t
Was thinking the same thing. I'm going to order a green led from mtn electronics unless I find it something else and put it in a c8 host and see how it compares to my L17.
What led and driver setup did you use in your C8?
It’s an xp-e2 from Mtn. I bought a green one as well, just haven’t put it in a light yet. Driver is a standard convoy 8 x 7135
Buy an acebeam and find out, so you can be sure.
Thanks. Going to order a green one and put it in a C8 host just to see how big or not the difference is compared to the L17.
It seems the L17 I have reviewed on this thread has died silently being a shelf-queen in my closet. :((
Well, maybe she felt lonely and heartbroken being used only once ever since I made the review. She would let me turn her on anymore, regardless what buttons I tried to push on her. :TIRED:
Strange as she was in good company with some more Acebeam flashlights and the Acebeam battery inside was still clocking at 4.10V. I also gave her an organ transplant (battery exchange) but she felt no love for me anymore. RIP, Acebeam L17. :(
Supplemental: Maybe this story will still have an happy ending as one of Acebeam's official retailers will be so kind to exchange the defective unit by a new one.
Did you long press for 5 seconds? I thought mine died until I realized it was the electronic lockout.
Yep. You need to hold the button for 5 sec or so until it blinks. It might be locked. Acebeam are pretty good lights and shouldn’t break. If it has, send it back for warranty since it has 5 year warranty.
Oh dear… 
That might be possible indeed. Anyway, since it has a slightly faulty driver like maukka‘s L17 it will be exchanged anyway.
Hey Lux-Perpetua, I can't find a data sheet on the Osram KG CSLPM1.2 Green that you list as the emitter in the L17. Is it maybe spelled wrong?
Since it's so yellow, I'm thinking of swapping it with the KP CSLNM1.F1 from Osram but I want to compare specs first.
Well, here's my assumption:
I am 100% sure that Acebeam once stated the exact name of the emitter on their L17 website, as I mentioned here before...
https://budgetlightforum.com/t/-/62764/5
Now, they seem to have removed that detail from their specifications chart, for reasons unknown. I have looked for KG CSLPM1.2 on Osram's website and I agree, it's nowhere to be found, see below.
This is however not unusual as I have another example from Osram's portfolio that cannot be google'd anymore. It's called Osram Ostar Projection Power LE A P0MQ. It is a amber colored LED and it can be driven up to 10A with an output of approx. 1,400 lumens. This powerful LED will probably be used in another interesting Wurkkos flashlight, see my thread about TS30S/TS30R. I have the datasheet here but it cannot be found on Osram's website anymore. Maybe Osram has discontinued this one as well as KG CSLPM1.2 and Acebeam was able to buy some residual reels of it.
Looking at Osram's current portfolio, there is no green 3030 or 4040 footprint LED available that can do the rated 2,000 lumens of Acebeam's L17.
Maybe Acebeam got a deal on a bunch of yellowish green leds before Osram gave up on them? I have to admit that the L17 has the most yellowish green color I have ever seen, but technically it is still green because you can see green in it. If I ever get that bezel removed and can remove the optics, I will put a real osram green in there like the KP CSLNM1.F1. Either that or I sell my green L17 for a steal of a deal!
