When it comes to flashlights, it’s no longer just about “how bright can it get?” Modern lights blend science, design, and portability into tools tailored for everything from night hikes to daily carry. Sure, lumens still matter—measuring raw output—but they tell only part of the story. High CRI (Color Rendering Index) can make colors look more natural, crucial for tasks like map reading or gear inspection, while color temperature influences how the beam cuts through fog or preserves your night vision. Then there’s the matter of size and packaging: a sleek penlight for pocket duty feels worlds apart from a tactical torch built like a tank. And powering it all? You’ll need to weigh the convenience and cost of disposable batteries against the long-term efficiency of rechargeables. In short, picking the right flashlight is as much about nuance as it is about brightness—and that’s where the fun begins.

Lumens: Measuring the Light Show

Lumens measure a flashlight’s total visible light output—essentially, how much light your eyes can see from the beam. Higher lumens generally mean a brighter light, but it’s not the whole story. Beam focus, lens design, and reflector shape can make a lower-lumen light feel just as bright in real-world use. Think of lumens as raw horsepower: impressive on paper, but only part of what determines performance.

CRI: Seeing True Colors

CRI, or Color Rendering Index, measures how accurately a light source reveals colors compared to natural sunlight, on a scale from 0 to 100. A high CRI flashlight—typically 90+—makes reds pop, blues look true, and subtle shades easier to distinguish, which is critical for tasks like map reading, gear inspection, or identifying wire colors. Lower CRI beams may look brighter on paper but can wash out details, making everything appear a bit dull or flat.

When do you require high CRI?

There is one tradeoff for high CRI, however. Higher CRI’s tend to have lower lumen output for the same amount of power consumption. Meaning, you’ll need more power to achieve the same level of brightness.

Other beam colors to consider:

Size & Packaging: Form Meets Function

A flashlight’s size and packaging dictate how—and where—you’ll carry it. Slim penlights slip unnoticed into a shirt pocket, while chunky tactical torches demand belt holsters or bag space. The body design also affects grip, switch placement, and durability, with materials ranging from lightweight polymers to knurled aluminum. In EDC terms, it’s the balance between “always there when you need it” and “worth the pocket real estate.”

Gone are the days of large bulky D-cell powered flashlights. Modern flashlights pack much more functionality and lighting prowess in smaller packages. Take for example, the Olight Arkfield Pro. It’s got 3 light modes — white light (1,300 lm), a green laser for presentations or inspections, and UV light for pet stains. The slim candy-bar profile slips easily in the pocket and feels natural in hand. Lastly, it features a 1,500 mAH battery capable of an 11-day max run time.

One should also consider the beam angle of the light. Do you need a 90-degree or prefer a traditional lighting angle? 90 degree or tactical lights can attach to your backpack strap, headlamp strap, or shirt, allowing for hands-free lighting. Traditional light angles are easier on your wrists during night outings.

Batteries: Disposable or Rechargeable?

Your flashlight is only as reliable as its power source. Disposable batteries (AA, AAA, CR123A) offer convenience and easy swaps in the field, while rechargeables (Li-ion, NiMH) deliver better long-term value and higher output. The right choice depends on your priorities—grab-and-go availability, or the efficiency and punch of a battery you can top up again and again.

For the sake of reliability, I suggest one of each — maybe a disposable-battery option in the car or bag as backup, since you can always buy batteries at gas stations — and a rechargeable as a daily driver. Pro tip: keep your batteries in a battery locker instead of the flashlight itself to prevent terminal oxidation.

Flashlights still beat phone lights for reliability, brightness, and focus—no battery-draining apps or clunky beams. Flashlights are also more position-able than phones — some with magnetic tail caps for overhead placement (car hood or metal rack). When you need steady, powerful light without distractions, a dedicated flashlight is still the smartest tool in the dark.

Aulumu - A01 Apple Watch Ultra case

Aulumu created — quite possibly — the toughest case for the Apple Watch Ultra, to go along with your extreme lifestyle. The watch case features DLC (diamond-like coating) coated aerospace-grade titanium faceplate. It also features a polycarbonate body with oversized aluminum buttons and a breathable FKM strap. Check it!

Olight imini

While not a new model, I thought it was appropriate to discuss the design genius of the Olight imini. The all-aluminum body can survive 1.5 meter drops and the light (50 lumen) is activated by pulling the body away from the magnetic tail cap. The handy light is perfect for key chains and bag attachments for super-quick deployment. Lastly, it features an integrated USB port on the tail cap for convenient charging. Check it!
