You’re probably here because you're tired of "cool white" LED beams that make everything look like a crime scene under fluorescent lights. Most cheap flashlights suck. They’re blue, they’re harsh, and they wash out colors until a red apple looks like a gray lump of coal. That's exactly why people are obsessed with the Convoy S6 with 519A. It’s basically the "budget king" of the flashlight world, but honestly, calling it budget feels like an insult to how well it actually performs.
Simon Mao, the man behind Convoy, has this weirdly brilliant business model where he just gives people exactly what they want for about twenty bucks. No fancy marketing. No blister packs. Just a cardboard box and a light that punches way above its weight class.
The S6 is a tube light. It's thin. It's black. It looks like every other flashlight from ten years ago, but the magic is what’s happening inside that reflector.
The Nichia 519A: Why Your Eyes Will Thank You
The real heart of this specific build is the Nichia 519A LED. If you haven't followed the flashlight hobby—yes, it’s a real hobby and it’s a rabbit hole—the 519A is currently the gold standard. It replaced the legendary 219B because it’s more efficient and can handle more power without turning into a puddle of solder.
What makes it special? High CRI.
Color Rendering Index (CRI) is a scale of 0 to 100. Most "Tactical" lights you see at big-box stores are around 70 CRI. They’re bright, sure, but they’re ugly. The 519A sits at roughly 95+ CRI. When you shine the Convoy S6 with 519A on a piece of wood, you see the deep reds and browns of the grain. If you’re tracking a blood trail or just looking for a specific colored wire under a dashboard, this light is a literal lifesaver. It’s the difference between seeing "stuff" and seeing "details."
Then there's the "dedoming" thing.

You can get the 519A with a tiny silicone dome over the emitter, or you can "dedome" it. Removing that dome makes the light warmer and significantly "rosier." It also increases the "throw"—how far the beam travels. Convoy offers these in different color temperatures, from a crisp 5000K down to a cozy, candle-like 2700K. If you want my advice, the 4500K is the sweet spot. It looks like pure afternoon sunlight.
S6 vs S2+: The Battle of the Reflectors
Most people start with the Convoy S2+. It’s the classic. But the Convoy S6 is arguably better for most people, and here is why.
The S6 has a deeper reflector.
It’s subtle. You might not even notice it just looking at them side-by-side on a table. But when you click that tail switch, the difference is obvious. A deeper reflector takes that beautiful light from the 519A and focuses it into a tighter "hotspot." The S2+ is a floodlight; it washes the whole area with light. The S6 gives you a usable beam that actually reaches out and touches things fifty yards away.
It’s a "pocket thrower" that doesn’t feel like a bulky searchlight.
I’ve carried both. The S2+ is great for walking the dog on a paved path. But if you’re out in the woods or scanning a dark backyard, the S6 reach is much more reassuring. It’s got that "punch" through the darkness. Plus, the S6 usually comes with a slightly more aggressive look—squared-off knurling that feels "grippy" even if your hands are wet or you’re wearing gloves.
The "Biscotti" Interface and Why It Matters
Most cheap lights force you to cycle through "High-Medium-Low-Strobe-SOS" every single time you turn it on. It’s annoying. It’s enough to make you want to throw the light in a river.
The Convoy S6 with 519A typically uses the "12-group" firmware, often referred to as Biscotti-style. It’s incredibly flexible. You can program it so it only has one mode (100% brightness). Or you can set it to start on 0.1% so you don't blind yourself when you wake up at 3 AM to check a noise.
Programming it is a bit of a rhythmic dance with the button—lots of half-presses and waiting for "buzzing" flashes—but once it’s set, you never have to touch it again.
Heat, Power, and Reality Checks
Let’s be real for a second. The S6 is a small aluminum tube. The 519A at 100% power generates a lot of heat.
If you leave this light on "Turbo" or 100% mode for five minutes, it’s going to get hot. Fast. This isn't a flaw; it's physics. There isn't enough surface area to shed that much heat. The good news is that the Convoy drivers have decent thermal regulation, but don't expect to run this at maximum brightness for an hour-long hike.
You’ll find yourself using it at 30% or 10% most of the time. Because the 519A is so efficient, 30% is still plenty of light for 90% of tasks.
Also, it takes an 18650 battery. Use a quality cell like a Sanyo GA or a Samsung 30Q. Don't buy those "9000mAh" fire-hazard batteries from auction sites. Get a real battery from a reputable vendor like Li-ion Wholesale or 18650BatteryStore. You want a flat-top, unprotected cell for the best fit, though the S6 is pretty forgiving with its dual springs.

Is It Actually Tough?
It’s an anodized aluminum tube with O-rings. It’s water-resistant enough to survive a rainstorm or a drop in a puddle. I wouldn't go scuba diving with it, but for everyday carry (EDC), it’s tank-like.
The lens is usually AR-coated (anti-reflective) glass. That's a high-end touch you don't usually see at this price point. It ensures that most of the lumens actually leave the light instead of bouncing back into the reflector.
Actionable Steps for Buying Your First Convoy S6
Buying a Convoy isn't like buying a Maglite at the hardware store. It’s a bit of a "choose your own adventure" experience.
- Pick your CCT (Color Temperature): If you want a natural look, go for 4500K or 5000K. If you want it to feel like an old-school incandescent bulb, go for 3000K or 2700K.
- Choose the Driver: Look for the "5A" or "linear" driver for the 519A. It provides a good balance of brightness without melting the internals.
- Decide on Dedoming: If you want a "rosy" tint and more distance, look for a "dedomed" option. If you want a pure, neutral white and a wider beam, keep the dome on.
- Get a Clip: Convoy sells a "screw-on" clip separately for a couple of bucks. Get it. The friction-fit clips that come on some lights are prone to popping off; the screw-on version turns the S6 into a permanent part of your pocket.
- Check the Official Store: Simon Mao operates the "Convoy Flashlight Store" on AliExpress. That is the source. Avoid third-party resellers who mark up the price 300% and don't know the specs.
The Convoy S6 with 519A represents the peak of "enthusiast" lighting meeting "common sense" pricing. It’s not just a tool; it’s an upgrade to how you see the world after dark. Once you see the colors it brings out, you’ll never go back to those "tactical" blue lights again. It's simply that much better.
