Read and follow the instructions to the letter. I received mine in good shape. First AC charging cycle was 18 hours-timed (as per instructions,) and it netted 4 HOURS AND 15 MINUTES of continuous lighting; timed, monitored, and recorded. Second charging cycle was 18 hours (as per instructions,) resulting in 4 HOURS AND 19 MINUTES of constant lighting. Final charging cycle was 18 hours (as per instructions.) Apparently the battery must be "exercised and conditioned." I'm looking forward to many, many, hours of service. Yes, a bit heavy and bulky, but you're going to get hours of cord-less service, if properly cared-for. Maybe not "as-bright" as the 3-4 ga-zillion candle-power spots, (I dunno, lumens and CP are not the same,) but this thing is cord-LESS, and out-of-the-box it lights for HOURS! I thought it would never shut-off! But, finally, "click" - off it went. I released the locking-trigger immediately (as per instructions.) I've not yet tried the car-adapter for lighting or charging.
This spotlight is incredible! A tree at 100-yards-measured (that's 300 feet-a football field) was amply illuminated for whatever you have in mind. Animals, people, vehicles, "targets," intruders, are going to be "lit-up" like daylight. Well, maybe not DAYLIGHT, but you get the idea... This is one BRIGHT SPOTLIGHT. At 100-yards, its "spot" is about 30-feet, with spill-over of 50-60-feet. Cordless, AC, or car adapter operable, this is one great spot. With the Coleman brand, I expect years of service. Numerous applications: hunting, walking/hiking, camping, home safety/surveillance, boating, auto-emergencies, power outages; got daylight? You will, with this spotlight... remember, it's CORD-LESS!
Thank-You Coleman, and Amazon. Great product! Great Service! Definitely RECOMMENDED!
UPDATE: After more careful "measuring," the spillover light (non-spot) area on a 100 yard "target" is about 100 yards wide. That gives plenty of "ambient" (non-spot) light to the left and right of the spot to see a whole lot of activity. Helpful when searching/monitoring wide areas in addition to the spot itself. Hope this helps in your decision. I'd buy again! :)
UPDATE: 12/30/15... After 3-1/2 years of use, through 11 (eleven) charging cycles, the spotlight is STILL working just fine, THANK YOU COLEMAN! Intermittent use, various uses and times, battery is holding well, when I think it's getting close to expiring, I run it down all the way, then re-charge it back up for 18 hours. When I need dependable BRIGHT LIGHT, I GRAB MY COLEMAN!
UPDATE! 1/14/2017 ...... 13th charging cycle, still going strong. Outstanding service... Sad-to-see it is now "unavailable."
UPDATE! 3/27/2021: Recharged through 19 charging cycles as per instructions, and still going strong!
