You're walking through Five Below, dodging a stray yoga ball and a pile of graphic tees, when you see it. It’s small, bright, and costs exactly five bucks (well, maybe five-fifty with the new pricing). The Solar Flare Five Below light has become one of those weird, viral sensations that nobody really expected. It’s a cheap solar-powered LED light, but in a world where everyone is obsessed with "prepping" and "aesthetic room decor," this little plastic cube has found a massive audience.
Honestly? It's kind of fascinating.
We live in an era where high-end camping gear costs hundreds of dollars. People drop a fortune on Goal Zero setups and BioLite kits. Then along comes this Five Below special that promises to do basically the same thing for the price of a latte. Is it actually good? Or is it just more plastic destined for a landfill?
What exactly is the Solar Flare Five Below light?
Technically, it's a "Solar Flare" branded portable LED lantern. If you’ve been on TikTok or Instagram lately, you’ve probably seen people hanging these from their backpacks or using them to create "vibey" lighting in their dorm rooms. It’s a simple concept: a small solar panel on top, a rechargeable battery inside, and a few high-output LEDs.
The build quality is... well, it’s Five Below quality. It feels light. It’s made of that specific kind of polycarbonate that sounds hollow when you tap it. But here’s the kicker: it actually works. In direct sunlight, the small photovoltaic cells (usually monocrystalline or polycrystalline silicon, depending on the specific batch) convert photons into electrical energy.
Physics doesn't care how much you paid for the device. The $P = IV$ equation—power equals current times voltage—applies just as much to a $5 light as it does to a $500 solar array. While the efficiency rating of the small panel on the Solar Flare is likely around 15% to 17%, that's enough to trickle-charge a small internal lithium-ion battery over the course of a sunny afternoon.
The Science of Budget Solar Tech
Let's get technical for a second because people often assume "cheap" means "fake." It isn't fake. Most of these budget solar gadgets use mass-produced components from manufacturers in Shenzhen. By the time a product like the Solar Flare Five Below hits the shelves, the technology inside has been commoditized to the point of being nearly free to produce.
The internal battery is usually a 14500 or a small Li-po cell. These aren't high-capacity powerhouses. You aren't going to run a microwave off this thing. But for a few LEDs? It's plenty. The LEDs themselves are surprisingly efficient, often pulling less than 0.5 watts while producing enough lumens to read a book in a dark tent.

One thing people get wrong is the charging time. You can't just leave this in a shady window and expect it to be full by nightfall. Most users who complain about the Solar Flare failing are actually just dealing with "under-saturated" panels. To get a real charge, you need direct, unblocked sunlight. Even a thin layer of window glass can reflect or absorb enough UV and infrared light to slow the charging process by 30% or more.
Why the Internet is Obsessed with This Specific Light
It’s the "Five Below Effect." There’s a psychological thrill in finding something functional for five bucks. But more than that, the Solar Flare has tapped into a few specific subcultures:
- The Budget Preppers: There is a growing movement of people who want emergency kits but don't have $2,000 to spend at a survival store. They buy ten of these lights, charge them up, and keep them in a "go-bag."
- The "Aesthetic" Crowd: Because the light is diffused, it creates a soft glow. It doesn't look like a harsh flashlight; it looks like a lantern.
- The Festival Goers: If you lose a $5 light at a music festival, you don't care. If it gets rained on and dies? Oh well.
The Solar Flare is basically the "fast fashion" of electronics. That sounds like a burn, and in some ways it is. We have to talk about the environmental impact of $5 electronics that aren't designed to be repaired. When the battery eventually hits its cycle limit—usually after 300 to 500 charges—the whole unit is basically toast unless you’re handy with a soldering iron.
Real World Performance: What to Expect
If you buy a Solar Flare Five Below light today, don't expect it to illuminate a football field. It’s meant for "task lighting" or "ambient lighting."
In my experience with these types of generic solar lanterns, the "high" setting usually lasts about 2 to 3 hours before it starts to noticeably dim. On "low," you might get 6 or 7 hours. That’s actually impressive for the price point.
One major tip: Check the seals. Since these are budget items, the quality control on the water-resistance can be hit or miss. If you're planning on using it for camping, take a tiny bit of clear silicone sealant or even just a strip of electrical tape and run it around the edge of the solar panel. This prevents dew and light rain from seeping into the circuitry. It’s a 30-second "mod" that can double the life of the device.
Comparing the Solar Flare to High-End Alternatives
Let's look at the "Luminaid" or "MPOWERD Luci" lights. Those are the gold standards. They usually cost between $25 and $60. They are waterproof, inflatable, and often have higher-capacity batteries that can even charge your phone.

The Solar Flare Five Below isn't a "Luci killer." It’s a different beast.
- Weight: The Solar Flare is heavier because it's hard plastic, not inflatable.
- Durability: If you drop the Solar Flare on a rock, the casing might crack. The inflatable ones just bounce.
- Brightness: High-end solar lanterns often hit 75 to 150 lumens. The Five Below version likely hovers around 40 to 60.
But here is the reality: for most people sitting on a patio or going on a backyard camping trip with their kids, 40 lumens is more than enough. You don't need a tactical searchlight to roast a marshmallow.
Addressing the "Does it actually charge?" Myth
There's a common rumor online that these cheap solar lights are "placebos" and that they only charge via the USB port (if they have one). While there are definitely some scam products on the market, the Solar Flare Five Below units are genuine solar-charging devices.
You can test this yourself if you have a multimeter. If you open the casing and measure the voltage coming off the panel while it’s in the sun, you’ll see a jump. The problem is that the panel is tiny. To fully charge a depleted battery, it might need 12 to 15 hours of perfect sunlight. Since we only get about 5 to 8 hours of "peak" sun a day, it might take two days to get a full charge from zero.
What Most People Get Wrong About Solar Flare Maintenance
You can't just throw this in a drawer for six months and expect it to work during a power outage. Lithium batteries hate being completely empty. They "deep discharge," and eventually, the internal chemistry gets wonky and won't accept a charge anymore.
If you're buying these for emergencies, you need to bring them out once every few months, let them run down a bit, and then charge them back up. Think of it like a car—you can't just let it sit in the garage for three years and expect the battery to be fine.
Actionable Steps for Your Solar Flare Five Below Light
If you've already picked one up or you're heading to the store to grab a few, here is how you actually get your money's worth:

The First Charge is Critical
Don't rely on the sun for the very first charge. Most of these units come with a micro-USB or USB-C port on the side. Plug it into the wall first. Get that battery to 100% capacity using steady AC power. This "primes" the battery and ensures the voltage levels are stable before you start relying on the slower, more erratic solar input.
Optimize the Angle
The sun isn't always directly overhead. If you lay the light flat on a table, you’re losing efficiency. Angle it so the panel is perpendicular to the sun's rays. In the northern hemisphere, this usually means angling it toward the south.
Keep the Panel Clean
Dust is the enemy of solar power. A thin layer of pollen or dust can drop your charging efficiency by 10% or more. Give the top a quick wipe with a damp cloth every time you put it out to charge.
Temperature Matters
Don't leave the light on a scorching hot car dashboard in 100-degree weather. While it needs sun to charge, extreme heat degrades lithium batteries rapidly. If it’s too hot to touch, it’s too hot for the battery. Try to find a spot that gets sun but also has a bit of a breeze.
The Solar Flare Five Below isn't a piece of professional mountaineering equipment. It’s a $5 gadget. But in a world where everything feels overpriced, there’s something genuinely cool about a little plastic box that turns sunlight into a nightlight. It’s a gateway into understanding renewable energy, and for the price of a sandwich, that’s a pretty good deal.
If you’re using it for your porch, your kids’ fort, or just as a "just in case" light in the junk drawer, it does exactly what it says on the tin. Just don't expect it to survive a trek across the Himalayas.
To make the most of your purchase, test the battery duration immediately after your first full USB charge. Note how many hours it stays bright; this gives you a baseline so you'll know in the future if the battery is starting to fail or if the solar panel isn't keeping up. If you notice the plastic starting to yellow or become brittle from UV exposure, a quick coat of UV-resistant clear spray (the kind used for outdoor furniture) can prevent the casing from cracking over time.
