  5. Here is a sequence of the CFL turning on as voltage is increased. Fulton-Montgomery Community College TEPP Technological Education Pathways Partnership NSF DUE 1003122

  6. A video of the bulb power on cycle. Fulton-Montgomery Community College TEPP Technological Education Pathways Partnership NSF DUE 1003122

  7. WIRES INTO MAIN TERMINALS OF LIGHT We remove the cover to show the control circuitry circuit board. COPPER SIDE OF BOARD Fulton-Montgomery Community College TEPP Technological Education Pathways Partnership NSF DUE 1003122

  8. LIGHT- CONTAINS ARGON GAS AND MERCURY VAPOR BASE BALLAST BALLAST HOUSING PHOSPHOR COATING Lots of circuitry packed inside… Fulton-Montgomery Community College TEPP Technological Education Pathways Partnership NSF DUE 1003122

  9. VOLTAGE FED HALF BRIDGE BI POLAR POWER SWITCHING TRANSISTOR DRIVER COIL A.KA. DRIVER TRANSFORMER TRANSFORMER The driver transformer saturates at a defined current level so that the lamp current is controlled in an indirect way.
