Steca Solsum ESL
5 W, 7 W, 11 W / 12 V energy-saving lights

The electronics of these 12 V DC energy-saving compact fluorescent lamps (CFLs) was developed by Steca and continuously improved.

Preheating, a high electronic efficiency and low thermal losses increase the service life of these CFLs to about 100,000 switch cycles. The Steca energy-saving lights feature a much higher efficiency (Im/W) than LEDs or incandescent bulbs.
