HF-EEFL

Thanks to the electrodes formed outside of the lamp tube, multiple lamps can be driven with one inverter(ballast). so the light box using HF-EEFL has lots of merits; simple structure, easy installation, low cost, etc. Furthermore, the low temperature of lamp surface implies the HF-EEFL is a safer and high efficient lamp.

HF-EEFL is the abbreviation for High-Flux EEFL(External Electrode Fluorescent Lamp) and the trademark of brighter lamps manufactured by EI Lighting Co., Ltd. Because there is no electrode inside of the lamp tube, there is no loss of electrode so that the extremely long life time is possible.
