MEGAMAN PowerLensTM Technology

Apr 15, 2010 MEGAMAN® has developed the patented PowerLensTM technology to empower the CFL reflectors with a higher luminous intensity that fulfills the EuP requirements of ‘directional lamps’.
According to the EuP requirements, a ‘directional lamp’ has to deliver at least 80% of light output within the light cone with an angle less than 120°. Applied with the PowerLensTM, MEGAMAN® CFL reflectors have made a significant improvement in elevating the luminous intensity and narrowing the beam angle, delivering an even more focused light cone for highlighting items and decors. For example, when powered by PowerLensTM, the luminous intensity of a MEGAMAN® CFL GU10 reflector, 11W, increases by 13.6% with a beam angle reduced from 119° to 90°.
