I have owned both the Petzl e+Lite and the Petzl Bindi. The Bindi, in my humble opinion, is a definite upgrade. It recharges incredibly quickly, and is very lightweight, while still including decent features and being adequately bright (the e+Lite failed miserably in this respect). BTW - you CAN use it while it's charging, provided you do what I did.....had a power bank kept in a breast pcket, and looped the charge cord through the shockcord so it stayed out of my face. Worked just fine! And contrary to some of the posts here, it does have a red light. There are two things I really like (and I didn't see it mentioned here, but forgive me if it was) about this model. One, is the ability to "lock" it so that the "on" button does not get pressed accidentally while in your pack. More than once, I've had shifting pack contents turn on, and completely wear down, my headlamp. Two, is the ability to wear around your neck, and angle the light different directions. After finding the e+Lite to not be bright enough to get down a sketchy trail in the dark, I had switched to Nightcore NU25, but I like this Bindi even better, and find it worth the price. It lasted 31 hours on low for me, before it died, and it's super light at less than 2 ounces (the NU25 is 2.9 on my scale). If you count grams but still want a comfortable, usable headlamp with a decent amount of lumens, plus the ability to recharge, this is a definite winner.
