A 48-inch, 24-watt LED T5 tube for offices, retail spaces, and warehouses, offering 5000K natural light with Type A+B dual-mode installation.
This SATCO S19966 LED T5 tube is a direct replacement for traditional fluorescent T5 lamps, delivering 3200 lumens of bright, energy-efficient light. The PET-coated frosted glass provides shatter resistance, making it a safe choice for commercial and industrial settings. With Type A+B operation, you can install it with existing ballasts or convert to ballast-bypass for simplified maintenance and energy savings.
Best for
- Offices and cubicle areas needing bright, natural light for task work
- Retail stores and showrooms where a daylight-like light enhances product displays
- Warehouses and industrial spaces requiring durable, shatter-resistant lighting
- Task lighting over workbenches or assembly lines
- Retrofit projects replacing old fluorescent T5 lamps
Not ideal for
- Residential living rooms or bedrooms where a softer, warmer light is preferred
- Outdoor applications - this tube is rated for damp locations, not wet
- Spaces with 120V-only dimming needs if you plan to use a reverse-phase dimmer on 277V (dimmable only at 120V)
How bright is it?
3200 lumens - about as bright as a 54W fluorescent T5, ideal for general and task lighting in commercial spaces. It's not a dim accent light; it's meant to illuminate a room.
Light color and feel
5000K natural light - a bright, daylight-like tone that mimics the sun at noon. It's invigorating and can help reduce eye strain in work environments. With a CRI of 80+, it renders colors reasonably well, though not as accurately as 90+ CRI lamps.
Sizing and fit
This tube measures 45.75 inches long and 0.62 inches in diameter, fitting standard T5 fixtures. It's a 4-foot replacement, so it works in most linear fluorescent troffers and strip lights. The G5 base (miniature bi-pin) ensures a secure fit.
