can I use a rectifier as a dimmer for halogen light bulbs?
I am wiring a custom exhaust hood, and am wondering if I could use a IN5402 rectifier diode rated at 3 amps, 200 PIV connected in series with a 1.9 amp halogen light load, running at 120 Volts AC in order to dim the lights in the hood at about half bright? Wondering specifically if I will run into any problems with the longevity of the "dimmer", or the life of the bulbs? Also wondering if any one might know how I could make a very simple circuit that could slow a fan down to about half speed. I am using single pole double throw bat handle switches to make a high and low setting. High will just go straight through, and low will go through the dimmer or speed reducing module.
