The UBA20261/2 circuits use half-bridge driver ICs setup to drive standard PLC-18W, G24q-2 socket-based lamps. In addition, similar lamps with a nominal lamp power of 16.5 W can also be driven. The total power drawn from the mains is about 18 W for mains voltages of 230 V or 120 V (RMS). UBA20261/2 boards can be configured to drive different Compact Fluorescent Lamps (CFL) of different power ratings. Driving different CFL is possible by changing the inductor tap and installing a different lamp capacitor.
