Halco’s ProLED Select T9 Powers Quick Circline Retrofits
Halco’s ProLED Select T9 Circline Hybrid Lamp provides a simple path to upgrade aging fluorescent circline fixtures with modern LED performance. The hybrid Type A/B design supports both ballast‑compatible and direct‑wire installs, which helps reduce surprises during retrofit work and keeps labor predictable across mixed‑condition sites.
Selectable color temperature allows installers to match existing light levels or shift a space toward cleaner, brighter output. With four CCT options ranging from 3500K to 6500K, one lamp adapts to kitchens, utility areas, stairwells, closets and other general lighting environments. Smooth, uniform distribution helps eliminate the shadowing common in older fluorescent systems, and the durable polycarbonate lens and housing support long‑term performance in residential and light commercial settings.
Performance is another advantage. The lamps deliver up to 132 lumens per watt with outputs between 1,400 and 2,100 lumens depending on size and CCT selection. CRI 80+ supports accurate color rendering in everyday applications and the L70 rating above 35,000 hours reduces maintenance cycles for property managers and facility teams. Universal 120-277V operation broadens compatibility across building types and the -20°C to 45°C operating range supports reliable performance in varied environments.
Rated for enclosed fixtures and compliant with FCC Part 15, the ProLED Select T9 Circline Hybrid Series lamps are suitable for residential, multifamily, healthcare, hospitality, retail and municipal applications.
