Lighting update for Feb. 23, 2009

There have been a couple of very interesting and hopeful stories on the lighting front that I think you will find both useful and entertaining.

The big news of course is that the City of Los Angeles is going to replace 140,000 street lights with new LED ones (  I assume that they are retrofitting most of the existing fixtures and the article claims that the plan calls for actually replacing 30,000 of existing fixtures with new.  I applaud the scope of the project and once again remind everyone that the quickest way to a green project is to show the accountants that the return on investment is worthwhile.

Along the same topic of streetlights comes a story on Treehugger and others ( about towns in Germany that have converted their streetlights to a light on demand via cellphone system.

Excerpt: “The solution seems to have started in the small town of Morgenröthe-Rautenkranz in the Erzegebirge. Over one and a half years ago, the 900 citizens of Morgenröthe-Rautenkranz were plunged into darkness each night, but given the option to turn the lights on by mobile telephone. Older citizens were concerned about their ability to master this new technology, but practice makes perfect. The first two weeks of the program, the lights remained on almost all night long as residents remained awake late for an opportunity to test the new system! But now the lights stay off except when needed. The town saves 4000 euros ($5300) per year. According to the Berliner Morgenpost daily newspaper, Morgenröthe-Rautenkranz is the inspiration for 4300 person community of Groß Pankow, the most recent community to consider on-call streetlight.

Next we have news from Japan of an LED replacement for the fluorescent tube. The story via ( tells of a Japanese company that has brought a model to market.

Excerpt: “The tube lamp is designed as a drop-in replacement for fluorescent tubes (not to be confused with compact fluorescent bulbs, aka. CFLs) and features a long silicon substrate with lots of LEDs mounted on it, enclosed in a glass tube. The unit is be a bit pricey at $306 compared to around $14 for a fluorescent tube. However, the rated life is 40,000 hours, nearly 8 times the normal life of a standard fluorescent tube. Another perk is that the LED tubes are mercury-free, while traditional fluorescent tubes feature toxic mercury.

I can’t wait for these to become more successful and for the prices to come down. What a great solution that uses existing fixtures!

Lastly we have a how to guide on how to best start use compact fluorescent light bulbs (CFL) and it covers the ground and has some very good suggestions:
