keith cwrote a review of Lezyne Micro Drive Front Light on September 26, 2014
Familiarity: I've put it through the wringer
I have 3 sets of these lights (front and rear for 3 bikes) and all 3 front lights share a common problem: they have far less than the advertised "burn" time and fail to hold a charge running in "daylight warning" mode. Specifically, when new (<6 months old) fully charged front lights showed the red "battery low" indicator when operating at ambient temperatures between 40-80 degrees F. Now, the low charge indicator appears within 15 minutes of run-time and the lights are about 1.5 years old. Curiously, the rear lights do not have this issue. The total run-time for front lights in daylight warning mode is about 2 hours when new. I've written to Lezyne about this issue a couple of times but the company never responded. In short, this might be a model you should carefully consider before purchasing.
