EDC & Keychain Lights

The rule that governs this whole category

The light you carry beats the light you own. Everyone who has bought a flashlight has at some point owned an excellent one they stopped carrying because it was heavy, printed on their trouser leg, or dug in when they sat down. The specification that predicts whether a light gets carried is mass and shape, and neither is on the front of the box.

So this hub ranks weight and pocketability above output, which is a genuine departure from the rest of the site. A 250-lumen light finishes above a 2,000-lumen one here and nowhere else, because in a pocket the 2,000-lumen light is a light that stayed at home.

What to buy first

Something under about 60 grams with a replaceable cell, a published water rating and a usable low mode. Wurkkos publishes 32 grams, a replaceable 14500, IPX8 and one hour fourteen minutes at 1,400 lumens for the TS10 V2 — a rare case of a budget light publishing its runtime at maximum output.

If flatness matters more than a replaceable cell — for a dress pocket, a shirt pocket, a scrubs pocket — the sealed designs are genuinely better shaped. Streamlight publishes 1.2 ounces for the MicroStream and 3.3 ounces for the flat-bodied Wedge, and accepts the sealed-cell trade to get there.

How the category divides

By cell format, mostly. Keychain lights on 130-to-750 mAh sealed cells or a 16340. Pocket lights on a 14500, which is the sweet spot: enough capacity to be useful, small enough to keep the light near 30 grams. And full-size pocket lights on an 18650, which adds roughly 45 grams and real length in exchange for several times the runtime.

The second division is switch position. A tail switch lets you use the light in a forward grip and signal with it; a side switch is easier to reach one-handed while holding something. Neither is better; they suit different hands and different jobs.

What decides price

Machining quality, the clip, and the charging arrangement. A deep-carry clip stiff enough not to slide off is a real manufacturing cost and it is the feature you will use most. Olight puts the charging contact in the cell on the i5R EOS, removing the port failure entirely at the cost of a proprietary battery. Both of those show up in the price and neither shows up in a lumen figure.

The mistake budget buyers make

Buying more output than a pocket can carry. A 1,000-lumen pocket light sounds better than a 300-lumen one and weighs more, runs shorter, gets hotter and gets left at home. Buy the light you will have on you, then find out whether you ever wanted more — most people do not.

The second mistake is ignoring the low mode. The mode you will use most on an everyday light is the dimmest one, because it does not destroy your night vision or wake anyone, and it runs almost indefinitely. A light without a good sub-10-lumen setting is missing the mode you will live in.
