Seems like barring any major technological differences, all bulbs should 
output roughly equal energies for a given wattage. Since photons are 
discrete quanta the actual number of photons emitted from a particular 
bulb can vary depending on its color (less higher energy photons - like 
blue and more lower energy photons - like red), but the overall energy 
output should be the same. Which brings to mind a question: Do plants 
care about photon quantities, or energies? Given that PPFD is used to 
measure photosynthetic potential, I assume it is the number of photons 
that matter. If that is the case, it seems like the lower the color 
temperature, the more effective it is for photosynthesis (generating 
more photons per watt).
