I’ve seen the Convoy S21A selling $15.99.
Are there less expensive, but still decent, 21700 lights are out there?
i think thats probably the cheaptest…
And, without doubt… the Conyoy is a great light too 
If you want a side switch, the older Sofirn SP33 (not V3, but what they still can the “new version”) is around $20 and a good light (but for a 26650 battery).
You may be correct.
Agreed, I’m a Convoy fan.
I have the original SP33… I’ve found that I don’t use it much.
I just purchased some 40T cells at a good price and am looking for a place to “store” them between charges. :sunglasses:
Kdlitker?
This one is cheaper in 2 ways (lower cost, and lower quality). I got one for free, but I’d take the Convoy any day.
thats just garbage, probably like 300 lumens max if even that… what a waste of battery in that…
Liion gave me an 18650 version of that light, when they shorted my order on some 21700 wraps they forgot to ship.
Here is the only cheap 21700 I own(XHP50.2 version).
And it’s a great light for $22.13, w/free shipping. Sofirn SD05
If you already have a P60 module you like, or can get one for less the $3, KDLitker do a 21700 host for $12.99 : http://kaidomain.com/Flashlight-DIY-and-Tools/diy-flashlight-shell-or-flashlight-host/KDLITKER-E6-21700-P60-Flashlight-Host-Black
EEWWW! I just threw up in my mouth a little. Haha.
Please don’t take offense, I did ask for cheap and I appreciate for the suggestion.

I forgot the SD-05! This is a really good light with some punch (good throw) and it runs very bright and wide (longer than most before thermal step down). If outdoor, the 6.5k would be my pick. If you don’t mind the ring switch (I can use it one handed, so it fine for me), it’s a good one for sure. Sadly, the 5k version I’ve been waiting for since Aug. (for actual diving) isn’t available.
Oops… New emitter! Might be improved if the led isn’t too cold. I might have to try one myself as I’m making a Sofirn order here soon. Going to grab one of the new SP36 Pro lights they just released.

I have one in my cart. This’ll be my first SST70, AND my first rotary switch, AND my first dive light. I hope I don’t hate the 6500K.
As cheap as a Convoy:
Yootoo SD2 (from Amutorch)
15,87€

Nice find… I like the SST20 4000K option.
My s21a is on its way…
Not only is it inexpensive, Simon is a joy to deal with AND you can get biscotti firmware…
3/5 modes is so lame
I really like mine, but it heats up fast. I put a flat white 2mm² in mine and its just great.(it has light OP reflector which helps with the beam quality.
S21a is in hand. Red ano, 5000k temp. 12 mode biscotti
$17.40
and a dam nice light at the price… love it.
