Convoy S21A - Flashlight Review

This is another nice flashlight from Convoy collection! It uses Nichia 519A, 5700K and is High CRI.
This version has a driver with 4 modes only, and has memory. It takes protected and unprotected 21700 batteries and can also take 18650s, if you use an adapter.
It is nice flashlight for a backpack or for "around the house" use, both because of the floody beam and also the colour rendition.
The flashlight was sent for review by flashlightbrand.com (non-affiliate), to whom I thank:

I have that MAO (stone white) and 519a 3500k. I changed my switch to metal RGB.

[@DinnerForkTongue]

Have the MAO too, but single 519A 5700K like this one, and a black one with a 3000K 519A (and a smooth reflector). The most I did was swap out the original (magenta AR-coated) lenses for Convoy's now-standard green AR-coated ones.
Very nice lights, don't think I'll be modding them.

how to turn/mod into quad?

[@MascaratumBLF]

You would need some kind of spacer (brass, copper or aluminium), to put between the quad MCPCB and the pill. I don't have a notion of the measurements (diameter/height) of that, though.
On BudgetLightForum, member "kiriba-ru" sells some spacers, you can check that in the thread: budgetlightforum.com/t/low-cost-copper-pills-spacers-optics-drop-ins-updated-23-10-2022/38581/1
In the USA, I am not sure if MTN Electrincs sells those spacers, but you can check in the store, as well: www.mtnelectronics.com/
Besides the spacer, you can also check the optic and MCPCB/LEDs there or in www.kaidomain.com (or other online sellers).

I hope the it helps! 👍
