Product Overview
Upgrade your fluorescent lighting with the Konlite 4ft T8 LED Tube Lights (20-Pack), a versatile, energy-efficient replacement for traditional T8 and T12 fluorescent tubes. Featuring durable aluminum housing with a polycarbonate (PC) lens, these commercial-grade LED tubes combine lightweight construction, excellent heat dissipation, and reliable long-term performance.
Designed for maximum flexibility, each 4-foot LED tube offers five selectable wattage settings (22W/20W/18W/15W/12W) and five adjustable color temperatures (3500K/4000K/5000K/5700K/6500K). With a factory default setting of 18W and 5000K, you can easily customize brightness and light color to suit different commercial and industrial environments.
Equipped with a standard G13 bi-pin base, these LED tubes support both Type A (ballast-compatible) and Type B (ballast bypass/direct-wire) installation, providing flexible retrofit options for existing fluorescent fixtures. The wattage selection feature operates in Type B mode only, while color temperature selection is available in both installation modes.
Choose between clear and frosted polycarbonate lenses to suit your lighting preferences. The PC lens provides uniform light distribution, while the aluminum housing offers structural durability. With a 140° wide beam angle, CRI above 80, and up to 2,840 lumens per tube, these fixtures provide reliable illumination for warehouses, parking garages, supermarkets, retail stores, offices, workshops, and other commercial spaces.
Operating on 120–277V, the Konlite 4ft T8 LED Tube Lights offer a rated lifespan of 50,000 hours (L70), ETL listing, DLC 6.0 Standard qualification, and a 5-year limited warranty.
Package Includes: 20 LED Tube Lights.
