One of my favourite 18650 flashlight “Nitecore EC21” weight exactly 60g, but this sadly does not include battery.
Still great little flashlight, tho.
edit.
Ah, title says 18350 not 18650. My bad.

With battery (and 18350 tube) a tad bit heavier than your limit, but I would think it’s the smallest/lightest (and brightest) in its class on the market.
unlikely - an 18350 (the Efest that I just looked up, anyway) weighs 55g in itself, leaving only 5g for the light….
Just weighed my aspire18350 1100, that test out continuously at 1223.
Its 25g total weight
Aspire 1100mAh (unprotected) = 25g
Keeppower IMR750mAh (unprotected) = 21g
A light - in size - like the new Klarus Mi1C or the Olight SMini would be good to have that weight (± 60g), but they only take 16340… :person_facepalming:
Manufacturers should listen/read more of what is said here !…
EDIT: Even the Astrolux E01 has 60g (+ battery = 85/86g, just like a S2+ without clip)…
The MecArmy PT16 is said to weigh 40 grams.
Add the 21 gram battery mentioned above…the total is 61.
Hum, the first light review I saw (that I can remember) on Youtube 
But…according to this review it is heavier than that 
If the Weight and size is that important to you, i think it is inevitable that you mod an existing light.
I managed to enlarge the inner size of an eagletac D25c just as much to fit an 18350 inside.
This in combination with a fet driver and an xp-l2 made it into the smallest pocket rocket i own.
Including the battery its weight is no more than 48 grams.
In highest mode it heats up very quickly.
Without modding: don’t mind the extra weight.
My Skilhunt H03 shortened with Astrolux S41 18350 tube is 65g with Aspire 18350 battery.
As you mention……
The weight is not 40 grams,
the correct weight is 52.
I was not anywhere near a scale, relying instead on the weight specified by Illumination Supply, where I purchased my light.
Except that it runs on 16340, not 18350.
Any idea on the actual weight?
Thanks!
On AliExpress you can find super cheap (<$2) skywolfeye flashlights that use 18650s, they have wall’s thin like soda cans, possibly fake or super old cree emitters, but I can’t really recommend them
S2+ with shorty tube and TIR?
Anyone ever weigh that?
MascaratumB weighed it at 86g, I believe.
It runs on both batteries.
If you look at the specifications and battery sizes, you will see 18350 is included, simply not mentioned in the title.
I did here: Convoy S2+ Desert Tan Available Now! - #1245 by MascaratumB
Although it has the reflector and not the TIR, that wouldn’t make the difference in this case.
The final weight with battery is above 86g (with a Keeppower battery, that is lighter than an Aspire), meaning that only the body of the light will weigh more than 60g. And that was the limit asked by Pete.
EDIT: BTW, has anyone ever seen this light/project ? I guess it ended in “nothing”, but this was a pretty light (and they had others) :heart_eyes:
It was from “helioslight”, and I guess this is not the actual “Heliuslight” (it has some posts and threads here on BLF)

Hmm. Figured with plastic TIR vs Al reflector, might lighten it up a bit.
Use a lighter cell? 
Why the 60g limit, though?
Sorry, I have no scale available.
With 18650 tube it’s 66 grams (+ cell).
