The Problem

LEDs are so different from Edison-style incandescent bulbs, that trying to create a drop-in replacement is problematic. This article in particular points out that current LED offerings have poor color spectrum, poor luminosity, and poor reliability. Ouch – they don’t sound very good at all, at least as screw-in replacements for a hundred year-old technology. While I think that they will eventually achieve a screw-in replacement that is fairly decent (look at this innovative offering from Phillips as an example), this pursuit is really the wrong approach. If you want to learn more about how LEDs work and how we can create some really special lighting that is hard or impossible to do with yesterday’s technology than read on. The best thing about LEDs is that the technology to solve our lighting problems is not in the future. It is available today. You just need to know … Read the rest
