I own a 192x3w Reflector for approx 6 months and with 10 autos under it I yielded over a lb.
also own 4 of the 300w "old style" panels band 2 180w ufos and have had excellent results
as well as a 600w "old style" all red flower spectrum light as a gift from Marshydros Sara
all of these lights perform hands down
Im fixing to stick the big reflector in a 1.5ftx3ftx8ft cab lol.
