I also retrofitted my wifes grow lights with LED tubes. They were cheap 4” florescent shop lights originally. Removed the ballasts and hotwired the sockets. Led tubes have been great. The electric bill went down as these are on a long time when she is starting seeds for the garden. I imagine they would be a cheap option for shop lights also.
