I bought construction extension cords that have sockets for five bulbs. They are fifty feet long and have a socket every ten feet. They even have a little plastic cage around the bulb to protect it. Got em at Home Depot. Heavy duty and should last for years. A bit pricier than what Tom is doing but they should last and I can use them elsewhere when they are not in the garden. I think they were $50 a piece.
