LED Retrofit E40 (Goliath)LED retrofit lamps with E40 (Goliath) socket are the energy-efficient replacement for conventional halogen and fluorescent lamps in existing sockets – no modification, no electrician, with immediate payback through up to 85% lower energy consumption. Application area: for industrial high-bay lights, street lights and high-pressure discharge lamp replacement (HQL/SON 250–400 W). These LED lamps operate with a service life of 15,000 to 50,000 operating hours, surpassing halogen equivalents by 10 to 25 times. Available colour temperatures: 2700 K warm white (atmosphere and restaurants), 3000 K warm white (office-warm), 4000 K neutral white (task lighting), 6500 K daylight white (detail work and laboratory). Colour rendering Ra > 80 standard; Ra > 90 on request. All lamps comply with the EU Ecodesign Directive and are CE-certified. For installation projects with larger quantities, we offer volume discounts and framework agreements. Please specify socket type, wattage, colour temperature and quantity when enquiring.
