my 1200w king has double chipped 10w diodes. it also draws 40w less than the viparspectra 600w but is also much brighter. diode coverage angles about the same for both lights. got 3 plants under one and 2 plants under the other with about 6in. overlap and the plants are all the same size, bushy, and green as fuck!the viparspectra uses all 5 watt led its true watt and a great spectrum . I never used it just did about 5 hours at work hours paid lol of research on them all great reviews .
