Usually I treat flood lighting for sports arenas as a process. Is there an exception for process lights?
A good expensive flood light is as follows:
OSRAM HQI®-TS metal halide lamp
Average life: 4,000 h
Luminous efficacy of lamp to 103 lm/W used for
for 2000 W per lamp
206000 lm per lamp
Lumens per life of lamp = 206 000 x 4 000 = 824 000 000 lumens
at 250 mg Hg per lamp --> 250 milligram = 250 000 000 000 picogram
i.e. 250 000 000 000 / (206 000 * 4 000) = 303 390 picograms / (lumen-hour)

The credit language seems pretty clear that there are no exceptions for process loads. The only exception is for screw-based CFLs.
You also have the option of not complying with the credit for 10% of your purchases.
