I was calculating how much this build was going to save compared to my normal set up

I pay $11.135 per 100 KWH
If I keep my current fixture which takes in 220 W for 7 hours a day, each year its going to cost me about $62.59 to run. If I upgrade and get this fixture then it should cost me about $18.82 a year. a savings of $43.77. This should pay for itself pretty quick
