The last 2 trips to HD left me empty handed in attempting to buy some replacement 8' fluorescent tubes for my shop. They were completely out of them both trips. I don't know if this is a supply chain issue or incentive to move towards LED replacements but this may be a good time to make the change. HD has 8' LED shop lights for around $100 each. Is there a better source for at least a dozen of them? What are you folks using for shop lighting?
