Small 21700 flashlight

I got the DQG 26650. I like it.
But I took on myself the task to find the ideal flashlight.
So now I’m gonna downsize a bit.
There aren’t many 21700 flashlights. The ones I saw are big.
But keeping the sizes of the DQG Tiny 18650 and 26650 in mind the size I’m after is:
97mm long and about 23mm diameter.
Preferably multi-led.

Anyone knows about such a light?
Is DQG working on 21700?

Chargers: 1xBasen BD01 5/5, 1x Gyrfalcon All-88 4/5, LiitoKala: 3x100 3/5, 2x202 3/5, 1x402 3/5., MiBoxer C4-12 3/5.
Flashlights: DQG Tiny III 26650 5/5, FiTorch MR35 3/5, Haikelite SC26 HD 3/5, Lumintop Tool AA/AAA 4/5, Nitecore LA10, Sofirn C01 BLF 3200k/5600k 2/5, Zebralight H600Fc 3/5.
Powerbanks: EasyAcc 26800 mAh 3/5, Xtar PB2 4/5, Xtar PB2S 5/5
Waiting for: (DQG Tiny) 21700 EDCs.

Size: 89mm x 28mmx24mm body

Looking at the photo that excludes the head. I guess the head included nears 45-50mm

23mm diameter is going to be basically impossible when the diameter of the battery is 21mm. That would leave a maximum wall thickness of less than 1mm after accounting for clearance between the battery and wall.

Also, 92mm long leaves just 22mm for the tailcap, springs, driver, LED, optics/reflector, and glass.

The shortest 21700 light I can find is the Zebralight SC700, which is 108mm long, but has a 38mm head diameter.

The Acebeam EC65 is 114.5mm long, with a 27mm tube and 30mm head.

The Rofis MR30 is 126mm long, with a 29.8mm bezel.

Those are the most compact 21700 lights I can find at this time. While there are likely to be more compact options in the future, I still think your size requirements are going to be unreasonable.

The PL47 BlueSword linked has a24mm body. So that’s close enough to 23mm.

My 26650 flashlight is 92mm long. Click
92-65=27mm
So you are right 92mm for 21700 is 5mm short. Editted my OP. Thanks for pointing that out

If only Acebeam would make a non-rechargeable version of the EC65.

And lower the price by a $100.
And the sustained output closer to 1000 lm.
