Description:
STECA SOLSUM ESL - 11 WATTS - SAVING YOUR ENERGY
Steca designed and recently improved the electronic ballast of the 12 V DC compact fluorescent lamp (CFL). Preheating, high electronic efficiency and low thermal losses increase the lifetime of the CFL to more than 100.000 on / off switching cycles. The Steca CFLs show much higher lumen efficiencies (lm/W) compared to LED or incandescent lamps.
