Just thought I would add my opinion/experience to the discussion. I
run 2 of the DiNotte Ultralights, I also have the L&M Solo Logic MV,
and the Cygo Lite Hi-Flux LED light. The DiNotte light seemed a little
brighter than the L&M Solo in 10W mode but not 13W, using both DiNotte
lights appeared brighter than the Solo 13W mode but it was hard for me
to tell how much brighter. Because the L&M Solo can easily be aimed on
the fly it did give a much better long range but the downside is the
heat and power consumption not to mention the bulb cost (3 in the last
2 years). The Cygo Lite was no match even with the Ultrlight in low
mode but the "be seen" aspect was greater with both the Solo and the
Cygo Lite based on a single light. I believe this is because of the
larger reflectors of those lights, which really pays off for this
aspect; the DiNotte uses a lens but is still very bright as a "be
seen" light.
The DiNotte has a better cheaper battery solution since AA batteries
are cheap and plentiful. You can make a cable by using (removing) the
top connector of a cheap 9V battery and using 9-volt battery connectors
from Radio Shack (solder the leads to the connector) to run 2 packs of
AA cells in parallel to get better run time. Tenergy batteries are only
about $1 each (+ shipping) on ebay when you purchase 16 or more. BTW
don't use Radio Shack battery holders, they are really cheap and
don't work well with the high current drain of the light.
You can also change the lens with any good Luxeon 3W or 5W lens for
different beam spreads, DiNotte recommended Fraen lenses
http://www.luxeonstar.com/item.php?id=741&link_str=121::123&partno=FHS-HMB1-LB01-0
is just one source.
You might just wrap the battery pack in a lunch sandwich bag (not the
Zip Lock kind), which basically waterproofs it from rain.
Overall the light is easy to open to change lenses and if you have good
soldering skills you can easily change the LED later on when better
ones are available provided they have the same electrical
characteristics. BTW the light has a voltage boosting circuit to get
the higher voltage needed from a 4.8V battery pack so it does draw
about 1250 milliamps (measured) in high mode. Which works out to
2300/1250 = 1 hr 50 min. using the supplied batteries.
Over a 2-year period I believe the light will be cheaper to operate
than the L&M Solo Logic, which BTW is a great light.
