According to further embodiments of the inventive subject matter, current diversion circuits may utilize use voltage dividers instead of diodes to bias current path transistors. For example, as shown in FIG. 5, a current diversion circuit 500 may include a current path transistor Q1, biased with a network including a diode-connected transistor Q2 and resistors R1, R2. In a lighting apparatus in which multiple ones of such current diversion circuits are used along the lines of the apparatus 100 and 300 of FIGS. 1 and 3, for example, the resistors R1, R2 are chosen to provide different base bias voltages for respective ones of the current diversion circuits. It will be understood that embodiments of the present inventive subject matter are not limited to specific type of electrical components used in biasing the current path transistor Q1. For example, diode(s) may be used as shown in FIGS. 1 and 3, resistor(s) may be used as shown in FIG. 5, and/or Zener diodes may be used.
