Originally, I had two 15 watt incandescents in my 10 gallon tank. I have recently upgraded to two cfl bulbs that are 10 watt but equal to a 50 watt incandescent.
So what is my wpg? Do i have 100 watts in this tank because I am using two bulbs that are each EQUAL to 50 watts? Or did I lose wattage and power by switching to cfl?
For the record, these lights are much brighter and better looking
