Show me a 900 lumen 3 watt LED light and I'll teleport you to an
alternate universe with laws of physics different than we have here.
Would you drive your car with just a flashlight at night?
Its not about only lumens, that's like catching every drop of water out of
a garden hose and saying that a light gives a given usable visibility based
on it. Totally wrong.
Who cares about dimly lighting up owl nests and chimneys, nor being so
bright in the middle that your eye tunes out what's even slightly to the
side?
Usable visibility is about where the light goes.
Now picture a fine new German car's headlight. Precise high resolution
optics. No blinding oncoming drivers. An even beam pattern illuminating
the width of the roadway with an even brightness.
On hign power its enough to vaporize a vampire.
Imagine a bike light that doesn't blind your peripheral vision as part of
being bright in the middle?
What is bright anyway?
Lumens?
Lux?
The net lumen measurement within the German standard legal outline for
where a bike light beam may disperse? Or should we also subtract any lumen
count that's 50% or above the lumen measurement at the 50% sideways
midpoint of the beam? Or what the French or English require?
See
http://contour.com/stories/barry-beams-overpowers-car-headlights-on-foothill-expressway
for what I'm describing.
About Deal Extreme, if you buy a light from them it probably will last
through BTWD. But those lights also come with the Walmart guarantee,
basically that its good for the length of the register.
Though my lights aren't on the market yet, for BTWD next year, you can have
the finest usable visibility, with car headlight brightness, sitting on
your handlebar vaporizing every evil petroleum burning vampire that crosses
your path, with durability to last for many many BTWD's to come.
Helmet Side Up,
Barry
