A 620nm red hunting kit with a remote switch and mount for $45.99.
We recommend the UltraFire WF-502BRX for hunters who prefer a red light for varmint and predator work. UltraFire lists a 620 to 630 nanometer red LED at 250 lumens with a 150 meter-plus beam, and red is a common choice for lights meant not to spook animals. The kit includes a protected 18650, a tactical remote pressure switch, a Picatinny rail mount, a steel clip, and a USB-C cable, and a hidden USB-C port lets you charge without removing the battery. The 6061-T6 body weighs 110 grams without the battery and carries an IP65 rating. The trade-offs are the single mode and the fixed beam.

Why we like it.
Red for wary game
A 620 to 630 nanometer red beam is a popular choice for lights used around wary animals, and UltraFire lists the light for predator and varmint hunting.
Kit that is ready to use
The package lists the flashlight, a protected 18650 battery, a remote pressure switch, a Picatinny rail mount, a steel clip, and a USB-C cable.
Hidden USB-C
A hidden charging port lets you charge the battery in the light. UltraFire lists an indicator that shows red while charging and green when full.
A few things to consider.
Single mode
There is one high mode, so there are no lower levels for map reading or close tasks.
Fixed beam
The beam is fixed focus with a 150 meter-plus distance. For longer throw, see the LR20X PRO.
Check your hunting rules
Rules about lights, colored lights, and rifle-mounted lights vary. Confirm local law before you hunt, and handle firearms safely.
