The Maiz Pro LAMP LED with internal ballast replaces HQL, HQI and NAV bulbs up to 125 watts. It offers a compact design, high luminous efficacy, reliability and low maintenance. The significantly higher efficiency and a high color rendering index make it possible to reduce energy consumption by at least 50% compared to conventional light sources. The illumination of the environment is not affected. The typical payback period is calculated as one to two years, depending on energy costs and operating hours. Considering the maintenance costs, this is much shorter.
