Trying to find the best smartwatch with flashlight built in, but not sure which REXQU model actually fits how you’ll use it? This guide compares all four — EnduroBeam, Beacon Pro, Ridgeline and Prisma — on beam strength, battery life, water resistance and price, so you can pick the right one instead of guessing.
A wrist flashlight sounds like a gimmick until the power goes out, or you’re fumbling for a tent zipper, or a dropped leash in the dark. Once you’ve used one, going back to holding a phone flashlight feels backwards. REXQU builds the feature into four different watches, each aimed at a slightly different buyer.
How to Choose the Best Smartwatch With Flashlight for You
Before comparing specs, it helps to answer three questions. First, is the flashlight the main reason you’re buying, or a nice-to-have on a watch you’d want anyway? Second, will it get properly wet — river crossings and downpours, or just rain and sweat? Third, do you also want extras like Bluetooth calling or the lightest possible watch on your wrist? The answers point to a different model every time.
Quick Answer: The Best Smartwatch With Flashlight by Use Case
- Longest flashlight battery life: REXQU EnduroBeam ($159.97) — 25–35 days per charge.
- Brightest beam + most water resistant: REXQU Beacon Pro ($149.97) — 20m+ beam, 5ATM.
- Flashlight plus hands-free calling: REXQU Ridgeline ($149.97) — Bluetooth calls, SOS.
- Lightest everyday carry: REXQU Prisma ($129.97) — 30 grams, biggest screen.
REXQU EnduroBeam: Best for Battery Life
The REXQU EnduroBeam pairs a high-brightness, focused-beam LED with an SOS strobe mode, with brightness adjustable straight from the watch’s scroll wheel — no digging through menus in the dark. An 1100mAh battery covers 25–35 days of typical use and roughly 200 days on standby, longer than any other model here. It runs a 1.43″ AMOLED at 466×466 resolution and carries a 3ATM water-resistance rating.
REXQU Beacon Pro: Best Beam and Water Resistance
The REXQU Beacon Pro throws a 20-metre-plus beam with dedicated UV and SOS light modes — enough to pitch a tent, find a trail marker, or check on a strange noise outside. It’s IPX8-rated to 5ATM, the highest water-resistance rating in this lineup, so river crossings and downpours aren’t a concern. A 525mAh battery runs 5–7 days of daily use and 15+ days on standby, with magnetic charging that fills it in about 2.5 hours.
REXQU Ridgeline: Best for Flashlight Plus Calls
The REXQU Ridgeline adds a side-mounted flashlight and UV light to Bluetooth calling and a one-press SOS emergency call — useful if you want to answer a call with gloves on or reach for a light under a hood without switching devices. It’s also 5ATM/IPX8-rated. A 400mAh battery runs about 7 days of normal use and up to 15 days on standby.
REXQU Prisma: Best for Everyday Carry
The REXQU Prisma is the lightest option at 30 grams, with the biggest display of the four (a 1.95″ AMOLED at 410×502) and a built-in flashlight mode for quick, everyday use — finding keys, checking a dark hallway, walking the dog before sunrise. It’s IP67-rated rather than ATM-rated, so it handles rain and sweat but isn’t built for submersion. A 340mAh battery delivers 5–7 days of normal use and up to 30 days on standby, and it comes in six colors.

Why Water-Resistance Ratings Aren’t All the Same
Anyone reaching for a wrist flashlight outdoors is also going to get it wet — rain, sweat, or a stream crossing. ATM and IP ratings both follow the international IP Code standard, which grades how well a device resists dust and water ingress (Wikipedia, IP Code). In practice, EnduroBeam’s 3ATM handles rain and splashes but not submersion; Beacon Pro and Ridgeline’s 5ATM/IPX8 rating goes further, tolerating river crossings and downpours; and Prisma’s IP67 rating covers rain and sweat but should come off before swimming.
Real Use Cases
For overnight camping or multi-day hikes, EnduroBeam’s month-long runtime means the flashlight is still there on day four. For trail runners and mountain bikers who get caught out after dark in wet weather, Beacon Pro’s brighter beam and higher water rating make more sense. Tradespeople and anyone who wants hands-free calling alongside a work light will get more daily use out of Ridgeline. And for everyday carry — home power outages, dark parking lots, walking a dog before sunrise — Prisma’s light weight and long standby make it easy to just always have on.
Screen Size and Weight Also Factor In
The flashlight isn’t the only thing that changes across these four. Prisma carries the biggest display (1.95″, 410×502) and the lightest body at 30 grams, which is why it doubles as an everyday-style watch rather than a purely outdoor one. EnduroBeam and Beacon Pro share a 1.43″ AMOLED at 466×466, while Ridgeline’s 1.8″ screen splits the difference. None of that changes how the flashlight itself performs, but it does affect how comfortable each watch feels for all-day wear when the beam isn’t in use.
Is the Flashlight Worth Paying Extra For?
Prisma, the cheapest of the four at $129.97, shows the best smartwatch with flashlight doesn’t have to come at a premium — it’s built into an otherwise everyday-style watch. The step up to EnduroBeam, Beacon Pro or Ridgeline mostly buys ruggedness and a stronger beam, not the flashlight feature itself. If outdoor use is occasional, Prisma covers the basics. If you genuinely need a bright, reliable beam outdoors on a regular basis, the extra $20–$30 for one of the rugged models is worth it for the beam strength and water rating alone.
Frequently Asked Questions
Do these use real LED flashlights, or is it just screen brightness? All four use a genuine LED flashlight separate from the display, not just a bright white screen.
Does using the flashlight drain the battery fast? Not much — a flashlight only draws power while it’s switched on, and most people use it in short bursts. The display and continuous heart-rate tracking cost far more battery over a full day than a few minutes of torch light.
Can I use the flashlight for signaling in an emergency? EnduroBeam, Beacon Pro and Ridgeline all include a dedicated SOS strobe mode built for exactly that.
Which one should I buy if I only care about the flashlight and nothing else? Prisma is the cheapest way in, but if brightness and beam distance matter most, Beacon Pro’s 20-metre throw is the strongest of the four.
Do any of them need a subscription to use the flashlight or see health data? No — all four work through a free companion app with no subscription required.
Whichever priority matters most to you — a month of battery, the brightest beam, hands-free calling, or the lightest everyday watch — REXQU has a genuine answer to what the best smartwatch with flashlight looks like for your routine.
