Streamlight c4 led is a great product - Streamlight Polystinger Rechargeable LED Flashlight

I have outfitted my entire crew with these flashlights. They are very durable, as some of us have dropped them down our elevator shafts and they still work just fine. Being polymer helps with electrical safety as well and they are still easy to wipe off and clean. I have and will continue to purchase more of these in the future.

My only "complaint" is that the picture on the website shows the older model LED. The newer one is a bit longer, works much better, and has variable outputs.
Pros: High output, good battery life, great quality
Cons: A bit pricey, but Opticsplanet has sells them the cheapest
