I do not know the wattage of her bulbs but take a look at these 250w DE bulbs.

Coralvue 20KK
Power(watts): 314
Voltage: 121.3
Current (amps): 2.75
Unshielded PPFD(output): 58.19
Shielded PPFD: 48.35
Giesemann Megachrome 13000k
Power: 336w
Voltage: 122.8V
Current: 2.94A
Unshielded PPFD: 112.9
Shielded PPFD: 87.8

So in a nutshell, the gs megachrome stomps it.
You may notice I compared a 20000k coralvue instead of a 15000k...in most cases the 20000ks have more than the 12000-15000k bulbs of most manufacturers... I will however search more looking for true specs on a 15000k cv bulb, just so we're doing apples and apples.
EDIT: I found a 250w mogul 15kk cv bulb.. it has ppfd of 74.9 from an M80 ballast. I'll keep looking for a DE 15kk bulb, if it exists.
