I got some cree mains units that do light the way but weakly.
the 11 watt ones that I have all f*ck my eyes up if I look at the cree unit when alight.
but as pir yard lights, at night, they do a job of lighting the way......
cheap as chips too..
to be honest, I cant see they are better than bulbs or bulb variants in car usage.
unless proved wrong, if you want spots, buy spotlights...
