Pros: The Protac is compact, lightweight, and provides powerful, bright light in a small form.

Cons: The belt or pocket clip is a little flimsy, and the battery power in such a small light can make the flashlight hot.

Sam Jones of Starlight Inn in Ayden, N.C., and Sam Jones BBQ in Raleigh, N.C., is an outlier when it comes to choosing his lights. Serving as a volunteer firefighter on top of running his barbeque brands, he prefers a powerful hand-held light for both off-site barbequing and fire department calls. His light of choice is the Protac 90X.

Sporting a clip that can attach to a belt or pocket and a 90-degree head angle, the 90X is suited for hands-free and hand-held use. With multiple intensity settings, the white LED light can provide ultra-bright 1,000 lumens, medium 600 lumens, and low-power 300 lumens with a run time of two to 24 hours, depending on the setting. The 90X has a lithium-ion battery that charges via a USB cable, a small form factor, and a weight of only five ounces.
