Granted, there are advantages to long run times and a bulb that lasts 50,000 hours but they simply will not produce enough usable light with reflectors designed to be used with filament bulbs to actually see where your going. The Cree XR-E Q5 high power emitter produces 228 lumen coupled with a good optic designed for that emitter will produce more light than an MR-16 20-watt halogen bulb and only consume 3 watts.
