I visited an older home in which the living room was indirectly lighted by a half-dozen incandescent bulbs above a soffit. The effect was very pleasing, but it got me wondering...
Those porcelain keyless lampholders are often mounted on garage walls or bulb-down on ceilings, but this was the first time I'd seen them mounted bulb-up. Is this an "approved" orientation? I don't see any mention of it in the lampholder data sheets.
Maybe I'm just being paranoid, and maybe it's not much different from a table or floor lamp, but I'm thinking about the hazard of foreign objects falling into an empty socket.
How would I find out if the UL listing restricts these to a specific orientation?
Thanks,
J.C.
