- 88. courtesy of Glenn Gara & 1st Source Lighting ICETRON OPERATING PRINCIPLE Ballast The system consists of an inductively coupled fluorescent lamp and a high frequency electronic ballast. The system uses magnetic-induction technology instead of an electrode at each end of the fluorescent tube to power the discharge. Removal of the electrodes eliminates one of the major life-limiting components of a fluorescent lamp.
- 89. courtesy of Glenn Gara & 1st Source Lighting ICETRON ® QUICKTRONIC ® SYSTEMS The ICETRON electrodeless fluorescent lamp is excited by a radio frequency (RF) magnetic field. The discharge current path forms a closed loop. The electric field that generates the discharge is initiated and maintained by an RF magnetic field concentrated within the ferromagnetic ring cores. In essence, the ICETRON lamp is an electrical transformer with a closed loop discharge serving as a one-turn secondary winding coupled to ferromagnetic cores whose primary windings are excited by an electronic RF power converter (the ballast). The RF power is evenly distributed along the discharge path. This allows a low profile geometry that avoids excessive thermal stress near the excitation area that can be typical of RF lamps with internal RF drives.

Editor's Notes
- A contributor to junction temperature is the ambient in which the luminaires are operated. This map shows the average night time temperatures across the United States using data from the national weather service. You should note that the average temperatures at night are 15⁰ C or lower across all but 3 states.

- House-side shield approximates Type III distribution for MH, but not successfully for CFL. Even without house-side shield, SSL beats MH and CFL in efficacy. SSL should be capable of much much better…other outdoor SSL luminaires at 50-70 lm/W.
