The Providence Journal has a great article in its Sunday issue about solar lighting and important factors to consider when deciding what kind of lights to get and how to install them.
One of the critical parts of the article is the discussion about how important LED advances have been to solar lighting:
A brighter light: LEDs are five times brighter than the bulbs previously used in solar lamps, drawing about 45 milliamps. And, unlike conventional bulbs, they emit light but not heat when electricity passes through them. One LED emits roughly the same brightness as a two-watt bulb. Still, the light produced is about half that produced by a candle, which isn’t that much. As one expert notes, it’s enough light for you to differentiate your sidewalk from your lawn, but not enough to keep you from falling over your kid’s bicycle.
I know a fair amount about the topic but even I learned a bit.
Great article!
