I'm sorry but we had a family health issue here and finally back to the computer again. 'brillmtb', I will be waiting for your comments after testing. My LED works extremely fine here, but in Tenn the land is rolling and hard to see what they will do at an extreme distance. In my area, the only flat land is what you grade flat. The LED's far exceed the halogen lights, and so much whiter, and I'm very happy with them. But I won't know until spring when I'll be traveling to see what they do in a very very open area. (I want to see what they will do between Gallup and Flagstaff, and is the longest, flattest streach I know.)
