I purchased this Streamlight PolyStinger LED Haz-Lo to stay in my truck, or when duty calls, to accompany us on roadtrips - particularly when traveling up to the mountains, and especially in the winter; or to the beach, especially when that includes the more desolate stretches.I knew I wanted something durable, big enough to hold onto, that wouldn't get lost easily, and that offered variable brightness. And above all, I wanted something in the Streamlight lineup.Also, I didn't buy this particular flashlight because I wanted or needed the brightest, furthest, whitest beam possible. Actually, one of the features that attracted me to it, was its ability to go very dim. Its bright mode is plenty bright enough for all practical purposes, while its mid-mode is a very serviceable brightness while offering good battery economy. Its hidden party trick however, is its ability to go very dim and extend its charge over 20 hours. This is what you want if you're stranded somewhere with an uncertain timeline for rescue - a dim mode that is about as bright as clear full-moon night that will allow you to navigate, perform basic tasks, and light up objects right in front of you.For its purpose (my purpose), the Haz-Lo is a fantastic option, especially with the two-pack car + wall charger. If you're looking for piercing brightness, look seriously at the Streamlight ProTac line - these lights serve a different purpose, and for that purpose, there really is nothing better that marries performance & quality from a USA-based company that stands behind their good brand.
