Flyercan I haven't had any updates in almost a year. Manny software issues with no fix in sight.

Flyercan Yeah, not even close. False claims. Mine had around 900mAh. :(

Flyercan I charged a dead battery from one and it got to 1200mAh, not 2200mAh. It is an 18650 3.7v Lithium Battery

Flyercan You can use the adhesive to stick magnets to it.

Flyercan Remove the screws on the back to remove the batteries.

Flyercan No,thisdoesn't have a lithium battery as it states in the description. A 3 cell NiMh. That being said, I doubt it will light for 6hrs straight or it have any where near 50watts of light. Not even sure it will fully charge the 3 cells in a day of sunlight and like Brocak said I am pretty sure it has no waterproof capabilities.. If I had my time back I would not have ordered these knowing this. UPDATE: It will run for more than 6hrs on a solar charge of a couple of days. Not sure yet if it needs to be in the sun that long, but it does stay lite for more than 7hrs on the low setting.

Flyercan I have many of these kinds of lights in eastern Quebec and they all work great. Even at -20°c. Not sure about any colder, but I doubt it would be an issue. This particular light is giving me issues. First 2 I had would not charge the battery. The replacements keep turning on without motion, killing the battery way before the night is over.
