This 2D 28-watt 4-pin fluorescent tube combines a generously sized square design with advanced electronic ballast compatibility, delivering broad, uniform illumination with improved energy efficiency and quieter operation. The expanded 198mm x 198mm footprint makes it ideal for larger ceiling fittings, commercial light boxes, and spacious residential areas where substantial light coverage is required alongside modern electronic control gear. Operating with a compatible electronic ballast (typical for 4-pin configurations), it produces a crisp cool white light at 4000K, offering balanced, neutral illumination that enhances visibility and creates a clean, professional ambiance suitable for contemporary interiors.
Engineered with a 4-pin base, this lamp is specifically designed for dedicated 2D fittings equipped with electronic ballasts, a configuration commonly found in modern residential, commercial, and hospitality installations. With an average rated life of approximately 10,000 hours, it offers extended service life that significantly reduces maintenance frequency and replacement costs. The non-dimmable operation ensures stable, flicker-free performance, making it a reliable choice for kitchens, living areas, retail displays, office spaces, and commercial environments where consistent, energy-efficient lighting in a larger square form factor with crisp white illumination is essential.

1. What is the difference between 2-pin and 4-pin 2D lamps for this 28w size?
2-pin 2D lamps are designed to operate with magnetic ballasts, while 4-pin versions like this 28W lamp are intended for electronic ballasts. Check your fixture’s ballast type before purchase to ensure compatibility.
2. Is this lamp dimmable?
No, this 2D 28w 4-pin fluorescent tube is non-dimmable. Using it with a dimmer switch may cause flickering, reduced lamp life, or damage to the lamp and electronic ballast.
3. Can I use this 4-pin lamp in a fixture designed for a 2-pin 2D tube?
No, the pin configuration and ballast requirements are different. A 4-pin lamp requires an electronic ballast, while a 2-pin fixture uses a magnetic ballast. Always match the pin configuration and ballast type.
4. Can I use this 28w lamp to replace a 16w or 38w 2D lamp?
No, replacement must be made with a lamp of the same wattage and pin configuration unless the fixture manufacturer specifies otherwise. This 28W model is intended as a direct replacement for other 28W 4-pin 2D tubes.
5. Where is this lamp best applied?
Its larger square size, crisp 4000K output, and electronic ballast compatibility make it ideal for modern flush-mounted ceiling fittings in kitchens and living areas, commercial light boxes, retail display areas, office spaces, and contemporary residential and commercial environments requiring broad, neutral illumination with quiet, flicker-free operation.
