Predator Hunting Lights: Ultrafire WF-501B LED Review

The Ultrafire WF-501B LED flashlight is a good little predator calling light. For around $10, this LED light is hard to beat. It throws enough beam to light up eyes at 100 yards and is a perfect light for in-close calling coyotes, fox, raccoon or other night time predators like owls. The 501B is powered by one 18650 series rechargeable battery or two CR123A batteries and has a sturdy aluminum housing.

The Ultrafire 501B is a single mode LED flashlight and throws a good beam of light. The switch is a clicky type located on the tailcap, which is a little loud, but this can be swapped out with a pressure switch tailcap for $3.99. The pressure switch is designed to be used for mounting the 501B to a scope or gun mount and also enables the light to be turned on and off silently.

Bonus Tip

If you are using the Ultrafire WF-501B as a shooting light or gun mounted light, you’ll want to “shroud” the outer halo of the beam. especially if you are mounting it on a rifle scope. This will keep the beam focused on the target and will not let the outer edges of the beam’s halo cast light on to the gun barrel which may give you away and spook your target.

A standard size Rx prescription bottle fits nice and snug over the lens. Just cut the bottom of the bottle out with a razor knife and either paint the bottle with black plastic adhering spray paint, or like I did below, just wrap the outside of the bottle with black electrical tape.
