Neal, I'm NOT being sarcastic.... I think there's an interesting point
here, which I have an inkling of, but ask the artist: You're exposing
through "diaphanous textiles," but looking for ultimate sharp ????
Question #2 is where in the world did you get two-bulb fixtures for, I
assume you mean, 24 inch bulbs. I tried for years to get them, but around
here could only find singles except for the kind with attached plastic
"diffuser" to go under kitchen cabinets.
Question #3 is would one of you folks please spell out what HID & HMO --
no, we know that, I mean HMI, stand for?
thanks,
Judy
