Maglite ML150LRX review

We have not tested this flashlight. We own none of the products on this site and have no laboratory. This review works from Maglite's own product page, read on October 4, 2026, and the arithmetic those figures allow.

Two figures make this light worth a page. 458 meters is the longest published beam distance of any duty-class light we cover — only the three dedicated long-range throwers and the DeWalt DCL043 jobsite spotlight, at 464 m, reach further. And Maglite publishes something almost nobody does: 80 percent of capacity remaining at 1,000 charge-discharge cycles. On a rechargeable light with a sealed pack, that second number decides how long you own a working tool rather than a tube.

What Maglite publishes

The two figures check each other

Forty-nine candela per lumen

That ratio is why the reach figure is not a typo. 1,082 lumens is mid-pack output — less than a ProTac HL-X, less than half a PD36R Pro — and it reaches 458 m where they reach 374 m and 380 m. The adjustable-focus reflector is doing the work, as it does across the Maglite range.

The cost is spill. A beam concentrated this hard puts a bright disc on a distant object and comparatively little light around your feet, which is excellent across a yard and awkward in a corridor. Throw versus flood covers the trade, and our throwers page ranks the specialists that go further still — the Acebeam L19 at 1,300 m and the Nitecore P30i at 1,000 m.

Three hours fifteen at full output

3 h 15 min at 1,082 lumens is a strong figure in this company. The ProTac HL-X publishes 1.5 hours at 1,300 lumens and the Stinger 2020 two hours at 2,000. Among the duty-class lights, only the Fenix PD36R Pro beats it outright, at 3 h 30 min from 2,800 lumens — the more impressive figure of the two. Maglite's own ML300L runs 32 hours at its full 746 lumens, but it does that on three alkaline D cells and weighs 748 g.

Under FL 1 those runtimes run until output falls to 10 percent of the reading taken 30 seconds after switch-on, so they already include whatever thermal step-down the light does. That makes them working figures rather than bursts — see how runtime is defined.

What Maglite does not publish is the cell capacity, in either milliamp-hours or watt-hours. That is the one real gap in the sheet, and it means the stored energy this site normally computes for every rechargeable cannot be derived here.

The battery chemistry, and the figure nobody else states

The chemistry is why. LiFePO4 holds less energy per gram than the lithium-ion in most rechargeable lights, which is part of why this one weighs 431 g — but it tolerates far more cycles and is markedly more stable at temperature. On a light expected to live on a charger in a vehicle for years, that is the right trade and a deliberate one.

The charging figures follow the same logic: about 80 percent in roughly 30 minutes, and 2.5 hours to full. A thirty-minute top-up between calls is a genuinely useful property that no other light we cover publishes.

Four function sets, which is more interface than it sounds

Maglite publishes four selectable function sets rather than a single mode cycle:

• General — Full Power / Low Power / Eco
• Outdoor — Full Power / Low Power / Strobe
• Law Enforcement — Momentary / Full Power / Eco
• Tactical — Momentary / Full Power / Strobe

The point is what you can remove. Choose General and there is no strobe to cycle through in the dark. Choose Law Enforcement or Tactical and you get momentary-on, which is the switch behavior that actually distinguishes a duty light — see what makes a flashlight tactical. Streamlight's TEN-TAP does the same job on the ProTac HL-X and the PolyTac; almost nobody else offers it.

What it costs you

• IPX4 and 1 m. This is the weak part of the sheet and it is not close. IPX4 is splash resistance with no dust digit; 1 m is the lowest drop tier anyone here publishes. The ProTac HL-X publishes IP68 and 2 m, and the PolyTac 3 m.
• 431 g and 271 mm. Roughly two and a half times a ProTac HL-X and longer than most lights here. It belongs in a vehicle or a hand, not a pocket.
• No published cell capacity, so watt-hours and cost-to-run cannot be computed.
• A sealed pack, so there is no swapping in a spare at 2 a.m. the way the ProTac HL-X allows with two CR123A primaries.
• Strobe only in two of the four function sets, which is a feature rather than a flaw — but worth knowing if strobe is something you want always available.
• Candela and distance published at maximum output only. The per-mode outputs and runtimes are complete; the per-mode reach is not.

Who should buy something else

Skip it if the light will be rained on hard or dropped on concrete. IPX4 with a 1 m drop rating is the weakest durability pairing among the duty-class lights we cover. The Streamlight ProTac HL-X publishes IP68 and 2 m for meaningfully less money.

Skip it if you need a primary-cell fallback. A sealed pack with no alternative is the wrong arrangement for a go-bag. The Streamlight PolyTac runs on CR123A primaries that keep for roughly a decade.

Skip it if you want real distance. 458 m is excellent for a general-purpose light and modest against a specialist. The Nitecore P30i publishes 1,000 m.

Skip it if you want output. 1,082 lumens is mid-pack, and eight lights in our tactical set are brighter. If brightness is the point, the brightest tactical flashlights ranks them.

The verdict, stated as what it commits to

Maglite commits to 1,082 lumens for 3 hours 15 minutes, 138 for 18 hours, 25 for 79, 52,555 candela, 458 meters, 431 grams, 271 mm, IPX4, 1 m drop resistance, four selectable function sets, an 80-percent charge in half an hour, 80 percent of capacity at 1,000 cycles and a ten-year warranty — with the candela and distance figures reconciling exactly.

On disclosure that is among the best sheets on this site, and the cycle figure is genuinely unique. What it is not is tough by published rating, light, or bright. Buy it as a vehicle light that reaches a long way and will still hold a charge in a decade. If it has to survive weather and drops, buy the Streamlight — and Streamlight versus Maglite is the page that works that argument through properly.
