New LED MR16's will replace your old MR16 halogen bulbs. They last longer, burn cooler and use a fraction of the energy. MR16 are good to replace any bulb in track lighting, recessed cans or anywhere that you have an existing MR16 bulb. Halogen bulbs are typically 35 or 50 watts and our LED bulbs are 5 to 10 watts. These bulbs operate from a 12 volt supply source.
These are rated for damp locations so they can go outdoors under a porch but not in a wet location where they would have direct water on them, also they are rated for open type fixtures only.
