Advice for 80 square ft grow room

A question from a fellow grower:

Yes sir I am in the process of building an app. 80 square foot grow room in my basement. The one main question I have is on lighting floursent vises led grow lux. I do have a 600 watt led grow lux light. My question is my electric bill. I don’t want to raise a red flag with the electric company. Can you please advise.

Led’s more expensive to run than floursent’s - what the H@#^ Use both – More Light - Bigger Buds !!!
