Convoy L21A

Convoy/Thrower

Convoy L21A

Budget throw champion from Convoy. The L21A with SBT90.2 delivers incredible candela for the price. Simon's lights may not be pretty, but they perform.

Beam profile

Pencil thrower, about 4.3° wide. A tight, far-reaching column with almost no spill.

Estimated from 2,000 lm ÷ 450,000 cd — how this works

What owners report

Convoy L21A/4 sources reviewed

The original of Convoy's L21 thrower line, and owners describe it as built like a tank: perfect threads — deep, wide, rectangular-cut and well lubed — that screw together with a premium feel the price gives no right to expect. The beam is intense but keeps usable spill, which many dedicated throwers don't, and owners rate it great for the price and size.

The limitations are Convoy's plus one specific to the design: the battery tube only accepts genuine Samsung-dimension cells or equivalents, which frustrated an owner who wanted to build it into a super-thrower with a higher-drain cell. No accessories are included. And one owner found reverse-polarity protection didn't work as expected — though in Convoy style, Simon simply sent links to the replacement parts.

Consistently praised

  • Built like a tank, with thread quality owners single out
  • Intense beam that keeps usable spill, unlike many throwers
  • Great throw for the price and size
  • Wide emitter choice from Convoy's menu
  • Simon's legendary parts-and-repair support

Common complaints

  • The tube only accepts Samsung-dimension cells or equivalents
  • No accessories included
  • One owner found reverse-polarity protection didn't work as expected
  • No onboard charging
  • Superseded by the slimmer L21B for most buyers

Questions people ask

L21A or L21B?
The L21B is the slimmed revision and the usual recommendation now. The L21A remains worth buying when it's cheaper — the optics and build are the same family.
Which cells fit?
Genuine Samsung-dimension 21700s or exact equivalents. Cells with different button or protection geometry don't fit reliably, which also limits high-drain modding options.
Is the spill really usable?
For a dedicated thrower, yes — owners note you can walk with it, which isn't true of pencil-beam lights. It's the L21A's quiet advantage.
What if something breaks?
Contact Simon. There's no formal warranty, but the consistent owner experience — including the reverse-polarity case — is that he sends the parts to fix it.
