I believe the battery life should be 8 months, not 8 hours unless these things put out enough light to land a plane.
I was wondering about the battery life too! At only 8 hours battery life, you would be changing them every 1 to 2 days!
Hey guys- I’ll double check this for you, 8hrs does seem a little low. I’ll post an update as soon as I have more info.
UPDATE: Each day the light will stay on for 4 or 8 hours then turn off. Every day at the same time the light will turn back on. It takes two D cell batteries and will last up to 10 months.
