Electronic Ballast Design for HID Lamps   

Presently, the energy saving related issues have increasing importance. Substitution of low efficient equipment with high efficient ones are strongly recommended. HID lighting industry is one of these areas where the high efficient electronic ballasts can provide significant energy saving. The purpose of this site to present a simple overview about the specific features of HID lamps and related ballast requirements. A comparison method of different ballasts from energy saving viewpoint is presented. Some of these electronic ballast designs for HID lamps are also briefly introduced. Janos Melis (master degree in power electronics) has been involved in research and development of HID electronic ballasts for over 15 years. He has written several electronic ballast related papers and patents.

The Solar Harvest Organization - Promoting the Do It Yourself spirit...   

The Solar Harvest Organization, solar power information in Montana, alternative energy source, sustainable living. A search of Google will turn-up more than 900 websites featuring Do-It-Yourself. But less than 100 of these are alternative energy and out of those 90+ are trying to sell you something. (Dec. '02) The Harvest is here to help fill the void. We feature articles on what we've done and how it worked out, good or bad. We don't promote anyone's products but we do tell you who steps up to help and who's stuff we've used successfully. And the only thing we'll sell is equipment our members have taken out of service.
