I compared the new Surefire L1 ( Lux III ) & L2 on the
Relative Throw and Overall Output Charts located on
FlashlightReviews.com. I was surprised at what I found.
The L1 has more throw on high beam that the L2 on
high beam.
The L1 being 38.21 on the chart.
The L2 being 30.76 on the chart.
This measurement is defined as follows:
"This measurement takes the Lux at beam center and applies
the inverse square law. The inverse square law says that at
twice the distance a light is 1/4 as bright. By taking the square
root of all of the Lux measurements the numbers can be
directly compared. As a result, a light that reads 50 on the
chart has half the throw of a light that reads 100."
The L1 out throws the L2 !!! /ubbthreads/images/graemlins/icon3.gif How can this be ??? /ubbthreads/images/graemlins/thinking.gif
I realize that the L1 has an optical system that focuses the
beam to a tight spot, but has a very useable beam width at
50 to 100 feet. I can very adequately illuminate the entire
front of a shed, which is about 10 wide, at about 60 feet
from my deck.
What are your thoughts on this ??? /ubbthreads/images/graemlins/rant.gif
