Message-ID: Date: 30 Nov 90 10:50:13 GMT References: Distribution: sci.electronics Organization: Class of '90, Carnegie Mellon, Pittsburgh, PA Lines: 8 In-Reply-To: I didn't see the original question, but I'll answer this anyway. Yes and no. Some halogen lamps are 12V (others are 6V or 24V or 120V) so they need a power supply. Some manufacturers call this a ballast even though it is not a ballast in the sense of a florescent light ballast. Higher wattage halogen lamps are usually 120V ac. There are solid state power supplies rated for use with 12V halogen lamps available. -Simon Gatrall sg1q+@andrew.cmu.edu Brought to you by Super Global Mega Corp .com
