Exposure Diablo Mk4 – 2013 Mtbr Lights Shootout

Lights Lights Shootout

The Diablo is now in its fourth edition as it claims 1100 Lumens with a run time of one hour. It is still the light with the most polished construction and most functional helmet mount.

However, it is under attack from a whole host of self-contained lights that exhibit longer run times and bigger beam patterns.  The Diablo is still tops in brightness with a measured 920 Lumens but it’s also the most expensive one at $299.

Specifications:

  • Price: $299
  • Claimed Lumens: 1100 Lumens
  • Measured Lumens: 920 Lumens
  • Measured MTBR Lux: 100 Lux
  • Light Head Weight: 109 grams
  • Installed Weight: 121 grams
  • Run Time: 1 Hours
  • Category: Flashlight/High End

Strengths:

  • Still the brightest and lightest
  • Extremely small and bright with 100 gram weight.
  • Very innovative helmet and handlebar mounts are both included
  • Machining and quality are first rate
  • Carrying case is just right
  • Flexibility with piggyback battery option and many other options accepted by the Smart Port.
  • Excellent programmability and light levels now available

Weaknesses:

  • 920 measured Lumens falls short of 1100 Lumen claims.
  • 1:10 hour run time at full power is limited
  • $300 for this light is being threatened by a crop of new self-contained lights
  • Beam pattern should be wider at this brightness level

Mounting:

Helmet mounting is done with a snap-in pivoting ball system. Once installed, the light can be popped in and it can be adjusted in any direction. It rides a bit high on the helmet but it can pop off in the even of a collision with a low hanging branch. The light can be easily used as a trail flashlight too since it’s so easy to access.
