Nice article Richard! Wow, so much for adding 50-70% in light output when using a quality reflector since the number is more like 200-300%! Are you going to continue to test many different luminaires with different wattages? I personally run some of the 150w AB bulbs and love them, although the limited spread has to be kept in mind...but they serve a purpose. Also, thanks for the Reeftec article- excellent product.
