Interesting lamp but the Rebel whites for whatever reason have not been up to par and the lamp is very heavy in the deep red, something KNNA warned against. He recommended to balance the deep red with orange/red.
Also, 81W for 360 pounds (560 USD) is not priced competitively. Actual dissipation may be as low as 70W so that is $8/W. The Onyx bloom for example, is $2.15/W and uses Cree XML2.
