One of the defining features of an Eichler home is the set of globe lights that were original to the homes built in the 60s (the late-50s often had a pagoda-style light). We've learned the hard way the each tract has a slightly different design — some white, some black, some with domed celing mounts, some with cylindrical)... but one thing's for sure. If a bad 70s renovation found yours in the skip, then you were sort of hosed.
Recently, though, a few folks have brought these back to the marketplace. While there have always been corded choices from Seagull Lighting and a few others — even Ikea — these new versions from Schoolhouse Electric and Rejuvination Hardware come sthe closest with solid rods. The ones from Rejuvination are even customizeable, however, I'd guess the Schoolhouse ones could be made shorter if necessary.
Of course, you can always replace with reproduction Nelson Bubble Lamps, too.
Replacements for the globes themselves can be tricky (and expensive), so if you do buy a new set of lights, you might think to get another whole lamp for extras down the road.
