I bought my first quality light last year after reading on CPF selected for Quark X AA-2 for use at work. I've been happy with the light and versatility of it. This has gotten the ball rolling on buying more quality lights, planning on LD01 for my car keys and looking for a headlamp for work. I'm looking to adding a 4-5" EDC light to my now building collection. Looking for a light I can pocket easily for general use outdoors as I will be ATVing this year. The Quark X 123A-2 has caught my eye, more lumens for longer range/wider area and small enough to put in a pocket. What other lights with a similar size would be a good choice?
