I'm not real happy with this forum, because of too many negative comments. I have had thoughts of not offering the solution at all on this site. I have spent quite a bit of time and money to solve the lighting problem, handling mechanical and complicated electrical engineering problems and have gotten some nasty comments on this site for doing so. You'd think folks would be happy to know someone is seriously working on the problem and making progress. If it's so easy, then anyone on this site is totally free to develop a solution on their own. People don't understand the time needed for testing, development, waiting for parts, the costs, trying several solutions until one works, and the cost of all the research. And I know what a patent protects, as I have been a a patented inventor for some time. So I won't disclose all the details. You'll see a solution, but not every detail of the solution, certainly not enough to copy the solution. It's just good business. Mike S
