Someone lost a decimal point. Nextec Batteries (not included) are rated 1.3Ah at 12V which is 15.6 W-hrs capacity. That can drive a 13W light 72 minutes (1.2 hours). New batteries a little more, after 2 years a little less. Getting 300 lumens for over an hour out of a 1.3Ah 12V battery is great. Even better, these charge in 30 minutes so two batteries can take turns and last you all day, or all night. 12 Hours is 10 times more than anyone should hope for.
This Craftsman Nextec fluorescent is great. Lots of light, a very strong magnet to hold it in place, and no cord to mess with. I will be using this when I am working under the hood of my vehicle as well as other places such as in my crawl space doing the drainpipe cleanout job where I do not want 120 Volts around.
Very durable, great magnets very useful in getting the light where you need it, in tight engine compartments. Around 30 mins. per charge so buy 2 batteries (not included).
Very bright light.
Magnets are great, positioning for best lighting is a snap.
Cheap fluorescent bulb - not for tossing around the garage. You either have to already have a tool that uses the same rechargeable battery or you need to buy a battery AND charger
Had a hard time deciding between this light and the led work light. In the end I'm glad I picked this one (even if I will buy the LED in the future). I have used this light mounted to the underside of a hood, undercarriage, and laid it down on floorboards. Lights up the place. As others have said the specified runtime is inaccurate, but I have a second battery for a reason.
Bottom Line: This tool is exactly what I've come to expect from buying other tools in the Nextec family. Amazing value for money, very well built, and well designed. If I had to do it all again I would buy it again anytime.
