Light it Up: Why some LED lamps seem brighter than others

TORONTO, Ont. -- LEDs are much more energy-efficient than incandescent lights and they last much longer. Primarily for those two reasons, LEDs will be the light sources of the future, but they are not without their problems.

Headlights Again: Now digital

A few months ago I wrote a couple of times about headlights, complaining that the standard lamps offered in most vehicles -- from cars to heavy trucks -- are insufficient. Meaning, it's too easy to over-drive your lights at what are pretty ordinary speeds nowadays. The light just isn't thrown far enough down the road, reducing the ability of a driver to see far enough ahead to avoid an obstruction and maybe a catastrophic accident.

See Much?: We need better headlamps, period.

Clearly, there are issues with the headlights that show us what's ahead. Or maybe don't. We shouldn't be happy.
