after reading and reading all about LED GU10's I can't find any decent lights that can dim and are from a credible source. I have 3-50w halogen that don't dim. These lights aren't really needed but spot down onto the counter. Just looking for decent energy savings replacements. currently I have 6-50w halogen's that uses an insteon dimmer and usually is at around 50%. From what I believe LED's are about half as bright as halogens so this could work well. I plan on running the led's at 100% but want to dim to 25% when watching tv/movies. Really only need to have low,med,high or something. Does anyone have any energy saving suggestions for converting my 450w of halogen's into closer to 45w? These are all in-ceiling lights.

Hello, I have a 175-Watt Mercury Vapor dusk to dawn light mounted on my shed, that looks like this: [IMG]http://images.buzzillions.com/images_products/02/94/regent-175-watt-mercury-vapor-security-light-nh-1204m_166170_100.jpg[/IMG] I am looking to replace the light with a similar type. I went to the local hardware store and found a 100-Watt Metal Halide lamp for about $60, and a 65-Watt CFL lamp for about $30. My question is - which is the better light to use? Considering the local climate of hot summers (90+ degrees F) and cold winters (0-30 degrees F), I wonder if the fluorescent model would be effective at such cold temperatures. Do they both give about the same amount of light? Which is more efficient? What makes metal halide twice the cost of the CFL? Thanks in advance! -Gil :)
