Streamlight vs Fenix

These two brands get bought by the same people for the same jobs, and they lose to each other in a consistent way. On every matched pair in this comparison, Fenix publishes more lumens and Streamlight publishes more specifications. That is the whole comparison, and everything below is the detail underneath it.

It is worth saying at the start that both companies sit near the top of the disclosure ranking on this site. Neither hides behind a single lumen number the way several brands we cover do. The gap between them is narrow and specific, and it lands in exactly one place: what happens to the light after the first two minutes.

How we picked

Three matched pairs by role and size — the rechargeable flagships, the duty handhelds, and the pocket lights. Every figure is the maker's own, linked with the date we read it. We have handled none of these lights and do not claim to have; our methodology sets out what we do instead of testing.

Output, reach, and the column neither brand prints

Candela per lumen is not a published specification. Divide peak beam intensity by total output and you get a single number describing how tightly the reflector concentrates what the emitter makes. It is the fastest way to see what a light is actually for, and it is the column that makes this comparison legible.

Two things fall out of that table immediately. The first is that the Fenix PD36R Pro and the Streamlight ProTac HL-X reach within six meters of each other — 380 m against 374 m — while the Fenix publishes more than twice the output. The second is that two of the three Fenix lights here publish no beam figure at all, which means there is no honest way to put them in the reach column.

The disclosure gap, stated precisely

Both brands publish output. Both publish beam distance on their flagships. The difference is in the runtime column, and it is not a small one.

Read the two halves of that table against each other. Streamlight publishes a runtime for every mode on every light here. Fenix publishes one number, for the mode you will almost never select. The PD36R Pro's 42 hours is real, and it describes the light running at an output low enough to read a map by. What the PD36R Pro does at 2,800 lumens is not a figure Fenix puts on the page, which means nobody outside the company knows it.

Where the energy actually comes from

Fenix publishes cell capacity, which Streamlight mostly does not, and that is the one column where the disclosure runs the other way.

Durability, and what happens when the cell is flat

Streamlight publishes an ingress rating on every light in this comparison. Fenix publishes one on its headlamps but not on the handhelds we read, so the column is thin on one side through no fault of the arithmetic.

• Streamlight ProTac HL-X — IP68, dust tight and waterproof to 2 m. The strongest ingress figure in this comparison.
• Streamlight Stinger 2020 — IPX7, immersion to 1 m for 30 minutes, at 350 g.
• Streamlight PolyTac — IPX7, and at 119 g the lightest full-size light here.
• Streamlight MacroStream — IPX4, splashing water only. The weakest here, and worth knowing given it is the pocket light.
• Fenix PD36R Pro, PD35 V3.0, E18R V2.0 — no ingress rating in the pages we read. We will not print one we cannot source.

The dead-battery question splits the other way. Two of the four Streamlights take CR123A primaries, which you can buy at a gas station and store for a decade. The ProTac HL-X runs on either its pack or two CR123As, which is the most flexible power arrangement in this comparison. The Fenix lights here are rechargeable in practice, with the PD36R Pro's 21700 being a cell you can carry a spare of but not one you will find on a shelf in a small town.

The three matched pairs

Flagship: Fenix PD36R Pro vs Streamlight ProTac HL-X

The closest and most interesting pair on the page. The Fenix publishes 2,800 lumens against 1,300, and 380 m against 374 m — more than double the output for six extra meters of reach. That difference is entirely beam shape: the Streamlight concentrates 27 candela per lumen, the Fenix 13. The ProTac puts a tight hotspot inside substantial usable spill; the Fenix throws a broader, brighter wall of light.

Take the Fenix if you want the most light and the most stored energy, and you are content with a single runtime figure. Take the Streamlight if you need to know what the light does at every level, want IP68, or want a light that keeps working on primaries when the pack is flat.

Duty: Streamlight Stinger 2020 vs Fenix PD35 V3.0

Not a fair fight on disclosure. The Stinger 2020 publishes 2,000 lumens, 315 m, a three-mode runtime table, IPX7 and a weight. The PD35 V3.0 publishes 1,700 lumens and an 18650 cell, and that is where our sourcing ends — no beam distance, no runtime, no ingress rating, no weight. On specifications this is the most one-sided pair in the comparison, and the Streamlight wins it by default rather than by margin.

Pocket: Streamlight MacroStream vs Fenix E18R V2.0

The Fenix publishes 1,200 lumens against 500, and nothing else. The Streamlight publishes 500 lumens, 2,000 candela, 90 m, two runtimes, 62.4 g and IPX4 — the most completely documented small light on this site. If you want the brightest thing in your pocket, the E18R. If you want to know what is in your pocket, the MacroStream. At 4 candela per lumen the Streamlight is a pure flood, which for a light used at arm's length is the right shape.

Which brand should you buy

• You want the most output and the most stored energy — Fenix. 2,800 lm and 18 Wh on the PD36R Pro are both the highest figures here.
• You need to plan around runtime — Streamlight, without qualification. Every light publishes every mode.
• The light gets wet or dropped — Streamlight. IP68 and IPX7 against nothing published.
• You need it to run on cells you can buy anywhere — Streamlight. CR123A on two of these; see tactical flashlights for how that fits duty use.
• You want the best documented pocket light — the Streamlight MacroStream. See EDC flashlights for the wider field.
• You want reach per lumen — Streamlight ProTac HL-X, at 27 candela per lumen against 13. See best flashlight throwers if reach is the whole job.

What we would not do

We would not read Fenix's missing ingress ratings as meaning its lights are fragile. Fenix publishes IP68 on the HM65R-T headlamp, so the company clearly runs the tests; the handheld pages we read simply do not carry the figure. Absence of a published number is a disclosure fact, not a durability fact, and those two things are worth keeping apart.

We would also not buy the PD36R Pro expecting 2,800 lumens for 42 hours. Those two numbers describe opposite ends of the light's range and cannot both be true at once. That is not a Fenix problem specifically — it is what a single headline runtime figure always means, on any brand.
