Query: Pretty good, when they work

Bought a new house that came with these already installed. Light bulbs had burned out and fused to the socket inside the glass. Had to buy a whole new unit, which seemed like a waste, but these are reasonably priced. These things look great at night in my garden. I like the diffuse upward glow they give against my house. Only complaint is that the connectors work loose about once a season and need to be clamped back down onto the power line to get them to work. 4/5 stars.
