Customer Questions & Answers:

Q:How many lumens does it produce?

A:I don't know how many lumens it produces, but I can tell you that it's bright light really cuts through the dim mornings when I ride

Q:Is it two cr2032 batteries per light, or one cr2032 in each light?

A:Comes with two batteries per light, stacked with a plastic divider that you remove before using. 

Q:How do you turn on the lights on this thing?

A:After you take out the piece of paper between the batteries, you simply push the red led and it will work. 

Q:How many hours of use do you get from a set of batteries? And do the lights get progressively more dim as batteries start to wear out?

A:I have used the light for about 30 hours so far and it has not lost any power yet. I assume like all lights it will dim as the battles start to wear down
