In this discussion it’s really all going to be about your budget and what fits in your hand and how you are going to be able to carry it. Flashlights are so bright these days and sometimes strobe can be a major annoyance so if you don’t think you need it, don’t buy it. I have found for atleast the last 4 years that the Protac Series of flashlights from Streamlight are the best sellers for anyone that wants an everyday carry light, the price, the size, and the output. Now they are 260 Lumens on high and 13 Lumens at low. Low power on flashlights is usually used more than high power and is great on saving energy. I remember when I first started using the Streamlight Scorpions, I was impressed with the 130 Lumens it put out but i remember that it burned through batteries so much that it was time to look for something different.
There is a Protac 1L that takes 1 CR123 battery but I find that too easy to lose and the Streamlight Protac 2L flashlights are better for my hand and has a letter performance. I have been highly recommending these for years and recently had several Special Ops guys come in and tell me they are using them for defensive purposes. High lumens and strobing are tactics you can deploy that can work well for in buying you time to bolt, or deploy another defensive measure, pepper spray, fist, baton ect. We always try to keep them in stock, online and in our Showroom and most of our employees are carrying them so feel free to ask about them.
