Peerless Lighting, a division of Acuity brands, has announced HOT-5+ technology, its solution to obtaining optimal lumen output from T5 and T5HO lamps. The Lumen Optimizer, as it is called, acts as a thermostat adjuster, either preserving warm air around the cold spot of the lamp or extracting heat to ensure it is a constant 45 degrees Celsius and maintains a consistent optimal lumen output. The new technology has been implemented across all Peerless product lines using T5 and T5HO lamps.
