Reflectors are actually a bad way of transferring light. Anytime light has to bounce off of a reflector, it losses lumens and often part of its color spectrum.The light degrades with each reflection.With new technology, LEDs are directional in nature and need optics exclusively configured to optimize the spread of light over a given area to meet up with the light output patterns required for many applications. An LED can actually be built to project light in 60 degrees, 90 degrees or even 120 degrees for high bay lights. In other applications as wide as 150 degrees. Since the LED is sending the light directly where you need it, the reflector is not doing anything.
The standard today is 120 degree. Works very well from 14 ft up to 25ft. Above that we can consider narrower beam angles.
