Smartwatch flashlight brightness is the one spec REXQU doesn’t print a lumen number for — and neither does almost anyone else in this category. Instead of a marketing number, the useful comparison is beam distance, light modes, and how each watch is actually built to be used in the dark. Here’s how the four REXQU flashlight watches stack up, and which one fits how you’ll actually use the light.
How REXQU’s smartwatch flashlight brightness compares by model
REXQU sells four watches with a built-in torch, and each is tuned for a different job rather than a single “brightest wins” spec sheet. The Beacon Pro is the only one with a stated beam distance — a 20-metre throw, plus dedicated UV and SOS light modes, in a 5ATM waterproof body. The EnduroBeam leads with a high-brightness flashlight and an SOS strobe mode, backed by a 25–35 day battery so the light is there weeks after a normal watch would be dead. The Ridgeline pairs its flashlight with a UV light and Bluetooth calling in a 5ATM build, and the Prisma tucks a lower-power, everyday-use torch into a featherlight 30-gram watch with a 1.95-inch AMOLED display.
| Model | Flashlight | Water Resistance | Battery | Price |
|---|---|---|---|---|
| REXQU Beacon Pro | 20m beam + UV & SOS light | 5ATM | — | $149.97 |
| REXQU EnduroBeam | High-brightness + SOS strobe | 3ATM | 25–35 days | $159.97 |
| REXQU Ridgeline | Flashlight + UV light | 5ATM | — | $149.97 |
| REXQU Prisma | Built-in flashlight | IP67 | 5–7 days (30-day standby) | $129.97 |
Beam distance vs. everyday brightness: which one matters for you
Manufacturers rarely publish an official lumen figure for wrist-worn flashlights, because the useful measurement isn’t raw output — it’s whether the beam reaches far enough for what you’re doing. A 20-metre beam, like the Beacon Pro’s, is genuinely useful outdoors: it’ll light a trail marker, a tent stake, or the far corner of a campsite. That’s a different job from the light you want for reading a door lock in the dark or finding your dog’s leash, where a smaller, closer-range beam is honestly all you need.
This is why REXQU’s four watches aren’t ranked strictly brightest-to-dimmest. The EnduroBeam trades a stated beam distance for a high-brightness output that’s practical for a long time — its 25–35 day battery means the flashlight is still there on day 30, not just day three. The Prisma goes the other direction on purpose: a smaller, everyday-strength light built into a watch that’s meant to be worn to the office, not just the trailhead.
Picking flashlight brightness for your actual use case
For camping, hiking, or anywhere you need to see something more than a few feet away, the Beacon Pro’s 20-metre beam and UV light mode are the strongest match, and its 5ATM rating handles rain and creek crossings along the way. For a dog walk, a fuse box, or fumbling for keys at the door, any of the four is plenty — this is where the Prisma’s featherlight, everyday-wear build actually has the edge, since it’s the watch you’re most likely to already be wearing.
If the light is for emergencies specifically — a car breakdown, a power outage, a trail mishap — prioritize the SOS modes over raw brightness: the EnduroBeam’s SOS strobe and the Beacon Pro’s dedicated SOS light mode are both designed to be seen from a distance, which matters more in that moment than beam throw. The Ridgeline splits the difference with a flashlight, UV light, and Bluetooth calling in one rugged, 5ATM package, which is worth a look if you also want to take calls without pulling out your phone.
According to the ANSI FL1 flashlight standard — the industry benchmark most handheld flashlights are tested against — light output (lumens) and beam distance are actually two separate measurements, and a higher lumen count doesn’t always mean a light throws further. That’s a big part of why beam distance, not a lumen number, is the more honest way to compare smartwatch flashlight brightness across models that aren’t independently lab-tested.
Quick FAQ
Do any REXQU watches list an official lumen rating? No — none of the four publish a lumen figure. The Beacon Pro is the only model with a stated beam distance (20 metres).
Which REXQU flashlight watch is brightest for outdoor use? The Beacon Pro, thanks to its 20-metre beam and added UV light mode, both backed by 5ATM water resistance.
Which is best for everyday, indoor use? The Prisma — its flashlight is built for close-range tasks like keys, cupboards, and dark hallways, in a 30-gram watch light enough to wear all day.
There’s no single number that settles smartwatch flashlight brightness across these four watches — the right pick depends on whether you need a long beam outdoors, a light that survives weeks without a charge, or a torch built into a watch you’re already wearing. Compare all four side by side on the Smartwatches with Flashlight page, or start with the Beacon Pro if beam distance is your priority.
