Thanks for the tip Karin. I already had the fixtures so when I'm ready to change over I'll just go directly to LED. I'm wondering though about the possibility of using these reflectors and most of the wiring and just removing the ballasts. Have to do some research. Does that mean I can only work on my orchids at night? Yea, but this time of year I'm pretty much housebound anyway and find myself watching way too much TV. If I have to pot or mount a plant that could be done any time I suppose. More than half of my orchids are still upstairs so lots to do during the day.
