kitlane Posted July 7, 2011 Share Posted July 7, 2011 Not directly. Those design details affect the temperature that the filament can [be designed to] run at. The temperature alone determines the colour (hence "colour temperature", quantified in Kelvin, being used to describe the colour of the light). Possibly a bit too much physics for the OP, but "Black-body radiation" is the thing. Broadly speaking, yes. However, the fill gas can alter the colour. For example, the original "Quartz Iodine" lamps had a slight pink tinge to the light caused by the Iodine. Link to comment Share on other sites More sharing options...
