Need to light a display in a dark room with less-than-full brightness lights (ie, "mood" lighting). Would like to use small spots, but these are mostly quartz-halogen bulbs. To my understanding, QH bulbs must be run at full brightness, otherwise the filiments fail to "redeposit" properly.
Also, dimming LV lighting is not straight forward (out of the box; I know anything can be done with custom controls...)
This leaves mineature incandescant spots. Wiring is a pain (mains voltage, conduit, code requirements, etc.), but if all else fails, I'll do this using a dimmer.
