I am surprised that we are not seeing them mounted as reflector bulbs. CT that's what most auto manufacturers have been doing for years with ultra bright lighting. Mount a super reflective material to surround the bulb and aim it backwards to a larger reflector. I have a Pelican Flashlight that does have an ultra bright "usable" LED. Most just group a few together in a reflector, this one actually has a small tripod that aims the LED back towards the handle and is reflected back out through a normal reflector. This produces a focused beam that resembles a good Krypton type bulb.
