My stove's vent hood has a pair of 120VAC 50W MR16s with GU10 bases, e.g. these halogen bulbs. These are some of the last incandescent bulbs in my house, and I'd like to replace them with something that uses less power and lasts longer, e.g. these LED bulbs.
The curveball: the vent hood's light switch has three positions, "Off", "Bright" and "Dim". I'm 99% sure that the "Dim" position just puts a diode in series with the bulbs, so that you get half-wave rectified AC. The LED bulbs I'm interested in are "dimmable", but I'm sure the expected application is with the usual triac dimmer that gradually blocks parts of each half-pulse, rather than completely discarding half of the pulses. (BTW, we usually use the "Dim" setting, as it's plenty of light for us.)
How likely is it that a "dimmable" 120VAC LED bulb would function (hopefully at half brightness) when supplied with half-wave rectified power?
