Nitecore’s latest P‑series flashlights bring a replaceable 21700 cell, USB‑C charging, and a hot‑mode limit that caps the 5,000‑lumen peak. At $159 the P27iX offers a 100‑hour low‑mode runtime and a 2.5‑hour continuous output, positioning it between tactical lights and everyday carry tools.
What’s new
Nitecore unveiled two members of its new P‑series at IWA Germany – the compact P17iX and the larger P27iX. The P27iX hits a headline‑grabbing 5,000 lumens and a measured spotlight range of 470 yards (≈430 m). Its dimensions (5.6 inches long, 4.4 oz) keep it pocket‑friendly, while the redesign adds a replaceable 21700 lithium‑ion cell (≈20 Wh) and a USB‑C charging port protected by a metal flap.
The flashlight offers two distinct control schemes:
- A traditional main button near the head that cycles through flood, spot, and hybrid modes, with an LED indicator showing battery charge and the current brightness tier.
- Rear side switches that give instant access to the highest‑output flood and spot modes, plus a lock switch that prevents accidental activation when the unit gets hot.
A notable addition is the Search and Lumin‑Shield modes. These are short‑burst, ultra‑bright settings that automatically dim once the optics reach a thermal threshold, protecting the LED and the optics from damage. All other modes can run continuously.
How it compares
| Feature | Nitecore P27iX | Earlier P‑series (P17iX) | Typical EDC lights (e.g., Fenix PD36R) |
|---|---|---|---|
| Max output | 5,000 lm | 3,200 lm | 1,600 lm |
| Spot range | 470 yd (430 m) | 300 yd (275 m) | ~200 yd (180 m) |
| Battery | 21700, 20 Wh (replaceable) | 18650, 12 Wh (replaceable) | Integrated 21700, non‑replaceable |
| Continuous runtime (mid mode) | 2.5 h | 2 h | 1.5 h |
| Low‑mode runtime | 100 h | 80 h | 70 h |
| Charging | USB‑C (direct) + external charger | USB‑C + external | USB‑C only |
| Weight | 4.4 oz (125 g) | 3.8 oz (108 g) | 3.6 oz (102 g) |
| Price | $159 | $119 | $130 |
The P27iX’s replaceable cell is a clear advantage over many EDC lights that lock the battery inside. It means you can carry a spare 21700 on a hike or swap a depleted cell without waiting for a recharge. The USB‑C port also lets you top up the internal cell directly, a convenience that most tactical lights still lack.
Thermal management is where the P27iX diverges from its EDC siblings. The Search and Lumin‑Shield bursts push the LED to its limit, but a built‑in thermal sensor cuts the output once the head temperature approaches 70 °C. In practice, you can expect a few seconds of pure flood at 5,000 lm before the light steps down to a safer 3,200 lm. Continuous modes stay within safe thermal margins, delivering the advertised 2.5 hour runtime regardless of whether you run flood, spot, or a hybrid mix.
Runtimes of the Nitecore P27iX flashlight
The chart above (from Nitecore’s data sheet) shows the steep drop‑off in runtime as you climb the brightness ladder. At the lowest setting (0.01 W) the unit can linger for 100 hours, making it an excellent backup for long‑term camping or power‑outage scenarios. At the 5,000‑lm peak the runtime collapses to just under 2 minutes before the thermal limit kicks in.
Who it’s for
- Outdoor enthusiasts who need a bright, long‑range beam for navigation or search‑and‑rescue drills will appreciate the 470‑yard spot and the ability to swap batteries on the trail.
- Tactical users who require a quick‑access high‑output mode will find the rear switches and lock button useful, while the thermal throttling protects the optics during prolonged engagements.
- Everyday carry fans who value a lightweight, pocket‑sized unit will still enjoy the low‑mode endurance for everyday tasks like door‑bell checks or night‑time walks, without the bulk of a full‑size tactical light.
If you are primarily after a budget EDC light, the extra price over comparable 1,600‑lm models may not be justified. However, for anyone who wants a replaceable‑cell platform, USB‑C charging, and a high‑range spotlight in a compact package, the P27iX offers a compelling mix of power and practicality.
Availability – The P27iX is now orderable from Nitecore’s official store at $159. Shipping typically takes 3‑5 business days to North America and Europe.
