Nitecore vs Streamlight

This comparison contains the single most useful pair of numbers on this website, and both of them are Nitecore's. The Nitecore P30i publishes 2,000 lumens and 1,000 meters of reach. The Nitecore P20iX publishes 4,000 lumens and 221 meters. Twice the output, less than a quarter of the distance, same brand, same cell format, adjacent in the same catalog.

If you have ever suspected that the lumen figure on the box does not tell you how far a light sees, that pair settles it. And it frames the real difference between these two brands: Nitecore builds lights at both extremes of beam concentration and labels them with the same vocabulary, while Streamlight builds a narrower range and documents it far more completely.

How we picked

Three matched pairs by role — the long-throw duty lights, the high-output rechargeables, and the compact handhelds. Every figure is the maker's own, linked with the date we read it. Nitecore's own site would not serve us product pages from this build, so the Nitecore figures come from the brand's own listings and are labeled as such in every spec table. We have handled none of these lights; our methodology sets out what we do instead of testing.

The 40-fold spread inside one brand

Candela per lumen is not something either company publishes. Divide beam intensity by total output and you get a number describing how much of each lumen the reflector concentrates rather than spreads. Across this comparison it ranges from 3 to 125, and Nitecore owns both ends of it.

The table sorts almost perfectly into a shape nobody would predict from the lumen column. The brightest light here, the 4,000-lumen P20iX, sits at the bottom. The light that reaches furthest, by a factor of nearly three, has half its output. Streamlight's four lights cluster between 4 and 27; Nitecore's three span 3 to 125.

What each brand tells you, and what it does not

This is where the comparison stops being close. Streamlight publishes a nearly complete sheet on every light. Nitecore publishes two figures and stops.

That is not a rhetorical arrangement of the evidence. Across the three Nitecore lights in this comparison, we could not source a single runtime figure, a single weight, or a single ingress rating. Streamlight publishes all three on all three of its full-size lights, and publishes runtime for every mode rather than a headline maximum.

It is worth being precise about what this does and does not mean. Nitecore may well test all of these things; the pages available to us do not carry the results. A missing figure is a disclosure fact rather than a performance fact, and we are careful not to convert one into the other. But on a site that ranks lights by what can be checked, an unpublished runtime cannot count in a light's favor.

Power, and what happens when it runs out

Both brands are mostly rechargeable, and both offer one light that runs on cells from a corner shop.

• Nitecore P30i and P20iX — 21700 with USB-C charging built in. The largest common cell format, and a spare can be carried, but it is not something you will find in a rural gas station.
• Nitecore MT2A Pro — AA, dual-power compatible, with USB-C charging. The most flexible power arrangement Nitecore fields here, and the reason it earns a place despite the thinnest spec sheet.
• Streamlight ProTac HL-X — the SL-B26 pack or two CR123A lithium primaries. Primaries store for a decade and work when no charger exists.
• Streamlight PolyTac — two CR123A lithium, included. No charging to think about at all.
• Streamlight Stinger 2020 — the SL-B26 pack only. The one Streamlight here with no primary fallback.

Neither brand publishes a capacity figure for its packs, so the watt-hour arithmetic this site normally runs cannot be applied to either side. That is unusual — Fenix and Petzl both state capacity — and it means runtime here has to be taken from published hours or not at all. Flashlight runtime sets out how the computation works when the inputs exist.

The three matched pairs

Long throw: Nitecore P30i vs Streamlight ProTac HL-X

The Nitecore reaches 1,000 m against 374 m and publishes 700 more lumens. On the two figures Nitecore states, it wins decisively, and 250,000 candela is the second-highest intensity anywhere on this site. The Streamlight answers with a complete sheet: IP68, three published runtimes, a stated weight, CR123A fallback, and a candela figure that reconciles with its own distance claim.

Take the P30i if reach is genuinely the job — spotting across a field, a shoreline, a large yard. Take the ProTac HL-X for anything where you also need to know how long it lasts and whether it survives the weather. At 125 candela per lumen the P30i is a specialist, and its spill will be thin for close work.

Output: Nitecore P20iX vs Streamlight Stinger 2020

The P20iX publishes twice the lumens — 4,000 against 2,000 — and reaches 94 m less. This is the pair that shows what 4,000 lumens actually buys: an enormously wide, bright field at short range, and nothing extra at distance. The Stinger 2020 publishes a three-mode runtime table, IPX7 and a 350 g weight; the P20iX publishes none of the three.

For lighting a whole work area at close range the P20iX is a genuinely different tool and its low concentration is a feature, not a fault. For a duty light where the runtime at each level matters, the Stinger.

Compact: Nitecore MT2A Pro vs Streamlight PolyTac

The closest pair here, and the one where Nitecore's disclosure hurts least. The MT2A Pro publishes 1,000 lumens and 255 m from AA cells with USB-C charging, which is a genuinely useful combination. The PolyTac publishes 600 lumens, 214 m, three runtimes, 119 g and IPX7, on CR123A primaries. More light and better power flexibility against more information and a known ingress rating.

Which brand should you buy

• You need maximum reach — Nitecore P30i, and it is not close. 1,000 m and 250,000 computed candela. See best flashlight throwers.
• You need maximum output — Nitecore P20iX at 4,000 lm, provided you understand it will not reach far.
• You need to know runtime, weight or waterproofing before buying — Streamlight, on every light here.
• The light goes on a duty belt — Streamlight. Published ingress, published weight, primary-cell fallback. See police and duty flashlights.
• You want AA cells with modern charging — Nitecore MT2A Pro, the only light here that offers both.
• You want the most balanced light on the page — Streamlight ProTac HL-X, at 27 candela per lumen with a complete spec sheet.

What we would not do

We would not treat the P20iX's 4,000 lumens as making it the best light here, and we would not treat it as a bad light either. It is a flood built to fill a space, and 3 candela per lumen is what that looks like as a number. The mistake is only made when someone buys it expecting distance.

We would also not claim Nitecore's lights are less durable than Streamlight's. We do not know, because Nitecore does not publish ingress ratings on the pages we read, and we are not going to substitute a guess or another site's estimate for a figure the maker chose not to state.
