What are you trying to acheive? Fast more immediate color? or Nice Bronzing where you see peak color later in the day?

For more Immediate results try:
Heraeus Magic Sun 20/180R
LSI Signature Series VHOR 2M

For nice Bronze color:
LSI Signature Series HP VHOR 2M
Cosmolux 9K90 2M

Or for best results, pick 1 from each catagory & mix them every other lamp in the the unit, Will give great results.
