I’ve been looking at the new LED bulbs in stores; the kind that are intended to replace standard incandescent and fluorescent bulbs. The prices are still unreasonably high, but that doesn’t mean I won’t buy one to test it. I don’t remember where I read this (perhaps on the Insteon site or on SmartHome.com in a product manual) but somewhere it was suggested to use a 5W or higher LED bulb to avoid the bulb emitting light when the Insteon module is switched off.
