In many lines of work a small portable pocket flashlight with a couple of hundred lumens worth of capability is just fine, other times you need to be able to light up a large area quickly. The problem is finding a medium size flashlight that isn’t heavy and cumbersome but still has a capable lens set up. The balance between size vs weight vs power is an equation that many people have to calculate, particularly people in the law enforcement area. The same can be said about anyone building an emergency bag or a deployment bag. In my professional lives over the years I have had to play that balancing game and until recently the winner of the “Medium Size Flashlight” debate was the MagLite, that was until I was introduced to the Streamlight Protac 4 HL.

The Protac 4 HL is the big brother to the Streamlight HL-X that was recently reviewed by Matt Shin here on the site. Streamlight is no stranger to the world of flashlights, in fact the Eagleville, Pennsylvania based company has been at the leading edge of flashlightdevelopment for years. They offer over 100 different flashlights to cover almost any career field or need that you can think of. Streamlight makes lights for miners, military and law enforcement as well as all varieties of public safety and first responders and outdoorsman. In shorter terms, no matter your hobby or career chances are Streamlight has more than one model that will fit your needs. Enough about the company, let’s get back to why the Protac 4 HL is such a great light.
