Here's some stats for you. The new "XL versions of these lights have 50 more lumens and a regulated power supply (so the light doesn't dim as the battery drains.) Take the photos with a grain salt, I don't think they reflect what they look like in real world conditions. I would personally recommend getting a minimum of 200 lumens. The nice thing about having more light is you can run it on the medium or low setting if you find it too bright and extend the battery life. The Macro and Micro use a non-replaceable battery, once they drain you're out of luck until you can recharge them.
