I couldn't tell you! They're plain ol' 18W, 24"(?) common fluoros. My light meter laughs at them.
Clones need not be pounded with light. You just need to convince them it is daytime for 18-24 hours a day. Too much light isn't a good thing when a plant either has no or an underdeveloped root system.
I do run clones under 24hr light, but they are working pretty hard keeping up water intake in their first 24 hours after cutting, so I usually turn the lights off for their first 6 hours in the box.
