Watts vs Actual Watts used


Recently bought a Sun Blaze T5 light. Sticker says 648w (54x12 tubes).
Is this the actual watts I’m using or is it the equivalent of??
(looked for this topic before posting and didn’t see one)

Thanks, must have slept through Math class-LoL



that would be actual watts floro’s don’t do compared watts like led and cfl they have been around far too long to bullshit us with comparisons and since they are mainly used for stores malls office buildings they advertise simply watts which is all a business owner cares what will they cost me to run


Thank You
