Pros: Bulb Durability, Battery Life, Durability, Brightness
Restoring elec power demands 24-7 response. Night operations in any weather are the norm. Hands free light is a must for personal safety. I depend on and recommend the HP 11. Great spot throw to 300+ yds and flood 120 +\- deg. to 40 yds with the snap on diffuser. Headband adj. even over hard hats, use a little Velcro hook to give headband a bite on slippery hard hats. Bright white light, 4 levels plus strobe, 4 AA's = hrs or days of light depending high to low level. I own 2 Fenix headlights and 3 handhelds. Value, reliable and super bright. Everybody asks, "What kind of light is that, where can I get one?"
