Lezyne Power Drive – 2012 Mtbr Lights Shootout

Lights Shootout Video

MTBR Actual Lumens and Lumen Hours Measurements:

This light measured 31 lux ont the MTBR Lux setup.  In a laboratory environment with an integrating sphere, it measured at 295 actual lumens.

Lezyne Super Drive – $110 – 44 Mtbr Lux

Serfas True 500  $150.00 – 43 Mtbr Lux

So as you can see, the biggest competition for the Power Drive is the Super Drive from the same company, Lezyne.

We als want to note its honesty in reporting.  Claiming 300 lumens for a measured output of 295 lumens is one of the most honest we’ve seen to date  as the industry usually 30% off.

MTBR Actual Lumens and Lumen Hours Measurements:

Mtbr spent several days in a light laboratory facility and utilized ad $30k integrating sphere to measure some lights. The procedure is described in the video below.  This is very revealing as most lights claim a certain ‘Lumen Output’ without actually measuring the actual lumen output.  We are able to measure actual lumen output with this setup and the measurement for the Lezyne Power Drive is 295 lumens at the peak output.

Another excellent data point is the lumen-hour graph below.  It shows exactly how the light behaves over its whole run time.  A flat graph is good as it means the light output is constant over the its run and the user gets the same light outpu in hour one as in minute one of the light.  It also shows how long the actual run time lasts under ‘high’ mode.  The area inside the graph can be described as the total output of the light for one full battery charge.


  • Good light output for $90
  • Good reflector and lens quality provides a clear and artifact-free beam pattern
  • Field replaceable battery is a great feature for additional run time
  • USB charging plug is well protected against water and the elements
  • 2 hour run time at full power


  • The aluminum case looks inexpensive and uninspired
  • Non-intuitive switch action for turning on and off
  • No helmet mount available at this time
  • This light really pales in comparison to the Super Drive

Bottom Line:

It’s a very decent light at the $90 price point.  But since the ground-breaking Super Drive will be right beside it on the shelf (or the online selection) we really don’t see a compelling reason to buy this one. Get the Super Drive and be more impressed. This light is not as the other one and it’s not quite bright enough for aggressive trail riding.
