Meridian industrial LED retrofit lamps are designed as direct replacements for traditional SON and Metal Halide lamps in high bay and low bay fittings. Supplied complete with driver, they must be installed in rewired fittings with the ballast bypassed, ensuring efficient operation. Delivering approximately 100 lm/W with Ra>75, the lamps are available in 60W, 80W, 100W, and 120W versions, providing LED equivalents to 150W, 250W, 400W, and 600W HID lamps. Compatible with E40 and E27 lamp holders, they feature a transparent diffuser, robust construction, and are suitable for both open and enclosed fittings. Certified to UKCA, CE, and RoHS, these lamps are ideal for warehouses, shops, storage rooms, and industrial buildings, offering reliable, energy-efficient lighting performance.
