As an Ecologic® product, it features reduced mercury content and passes federal TCLP criteria for non-hazardous waste classification.

Industrial Grade Brilliance & Efficiency

Designed for professional facility management, the Dulux CF42DT/E series offers high lumen density in a compact form factor. Its 3000K color temperature provides a warm, inviting atmosphere without sacrificing the high-intensity illumination required for lobbies, warehouses, and hospitality venues. This lamp is specifically optimized for base-up operation, reaching peak performance at 35°C (95°F). To ensure safe operation, it must be used with a high-frequency ballast that includes an end-of-life (EOL) shutdown circuit, protecting the fixture from overheating at the end of the lamp's 12,000-hour service life.
