The new LUMILUX® lamps offer excellent luminous flux and economy, and improved environmental compatibility. Their loss of luminous flux over their entire service life has been reduced to around 8% compared with previous levels of 18% after 10,000 hours. With warm start ECGs, an average life of 20,000 hours and a service life of 18,000 hours (80% system luminous flux) can be achieved. LUMILUX® lamps are the environmentally friendly fluorescent lamps with a low mercury content that is perfectly adequate for all operating modes. Fluorescent lamps in LUMILUX® and BASIC light colours offer up to 10% energy savings compared with previous fluorescent lamps with a 38 mm tube diameter. They are designed to operate with conventional control gear and starters or with QUICKTRONIC® electronic control gear. If used in starter circuits, these lamps can operate with standard control gear and recommended compensation capacitors.
