Approximate lumens are 55 on high and 28 on low but I do caution that this is not necessarily the best way to think of art lighting. Instead, we recommend a Mini-spot for artwork up to 24" wide x 20" tall. We use specialty optics in our lights that are designed for more "useful" light. This is something not captured in lumens.
This light is rechargeable (charger included) so replacement batteries are not needed.
Please let us know if you have any other questions.
