Excellent (German) Blog with LED lighting knowledge

Everyone needs to safe energy. I recently decided to exchange my ancient conventional light bulbs with conventional LED retrofit lamps.Well to cut a long story short: It's not so easy. I got nice super efficient Zenaro retrofit lamps but for me they are extraordinary heavy and the light temperature is very cold (although I got warm white versions).I should have consulted the wonderful blog of Mr. Messer first. Tons of useful information rg. LED lighting.http://fastvoice.net
