Our verdict

A 1,000-lumen 18650 flashlight for under $30.

We recommend the UltraFire WF-502B for anyone who wants a bright, no-fuss flashlight at one of the lowest prices in our UltraFire lineup. UltraFire lists 1,000 lumens, a 200-meter beam, an aviation-grade aluminum body, and a 109 gram weight. It uses a single 18650 or two 16340 cells, which are easy to find, and you can choose a 1-mode version that turns on and off with one press or a 5-mode version. The Flashlight Package adds a 402 holster for a few dollars more. The trade-offs are that no battery is listed in the box and there is no onboard USB-C charging, so plan to buy a cell and charger.

Who should buy the WF-502B?

The WF-502B suits hikers, campers, and drivers who want a bright backup light for a pack, a car, or a nightstand at a very low price. If you want USB-C charging and an IP68 rating, the UltraFire T5 is the next step up.

1-mode, 5-mode, and holster options

The store lists four versions: 1 mode for $19.99, 5 mode for $20.99, and package versions with the 402 holster for $27.99 and $28.99. Choose the 1-mode version if you want the simplest operation, and the 5-mode version if you want lower levels for reading and camp tasks.

Output and beam

UltraFire lists 1,000 lumens and a 200-meter beam distance from the V6 LED. A reflector head gives a focused hotspot for seeing down a trail or across a campsite. As with all lumen ratings, they are manufacturer figures.

Batteries

UltraFire lists one 18650 rechargeable lithium battery or two 16340 batteries, with a voltage range of 3.7 to 8.4V. A protected 18650 is a sensible choice. Do not mix cells and use a charger made for lithium-ion.

Price and the UltraFire code

UltraFire lists the WF-502B from $19.99. Our UltraFire reader code applies on the official store at checkout.

Why we like it.

A price that is hard to beat

The WF-502B starts at $19.99, and the 5-mode version is $20.99. That is a very low price for a flashlight that UltraFire lists at 1,000 lumens and 200 meters.

Batteries you can find anywhere

It runs on one 18650 or two 16340 cells, and the 3.7 to 8.4V range means it works with both. Cells are widely sold, and a spare fits in a pocket.

Choose the interface you want

The 1-mode version is on or off with one press for glove-box simplicity, and the 5-mode version adds more levels. The package versions add a 402 holster for belt or bag carry.

A few things to consider.

No battery or charger is listed

The included-items list shows only the flashlight (and the holster in the package). Buy an 18650 and a charger before the trip, or see our 18650 vs 21700 guide.

Water rating is listed two ways

The specification table says IP65 and the description says IPX6. Both cover rain and splashes, but neither is a submersion rating, so keep it out of lakes.

Basic interface

There is no onboard USB-C charging or battery readout. If you want those, see the T5 or the EX3.
