Project testing - a pair of high power white LED's being assessed for suitability as streetlights, if a few more are used with them. Dazzlingly bright, and definitely should not be viewed directly.

LED based lights are likely to become more and more common over the next few years, in all forms of lighting. Low power, efficient, and unlike compact fluorescent types, there's no delay whilst they warm up. They're also free of mercury, unlike fluorescent types.
