LEDs are quickly becoming the way to go as color properties have improved dramatically and cost are rapidly declining. If you are considering installing dimming flourescent I have one recommendation - don't! Over thirty years in the business and flourescent dimming has been and still is a big problem and a headache. LED light sources approved for dimming are the way to go. We are using LED fixtures for interior and exterior lighting applications with much success. Yes, they cost a little more depending on the type and quality but the life is much greater, control is much easier and the energy usage is much, much lower.
