Overview

This 2D 28-watt 2-pin fluorescent tube features a generously sized square design measuring 198mm x 198mm, delivering broad, uniform illumination ideal for larger ceiling fittings, commercial light boxes, and residential spaces where substantial light coverage is required. The 2D configuration provides an even light distribution across its expanded footprint, making it particularly suitable for kitchens, living areas, retail environments, and hospitality settings where a low-profile aesthetic combined with ample brightness is desired. Operating with a compatible magnetic ballast (typical for 2-pin configurations), it produces a warm white light at 3500K, offering a softer, more inviting illumination that creates a comfortable and welcoming atmosphere.

Engineered with a 2-pin base, this lamp is designed for straightforward installation in dedicated 2D fittings commonly found in both residential and commercial environments. With an average rated life of approximately 10,000 hours, it provides extended service life that reduces maintenance frequency and replacement costs. The non-dimmable operation ensures stable, flicker-free performance, making it a dependable choice for kitchens, living rooms, retail displays, office areas, and hospitality venues where consistent, energy-efficient lighting in a larger square form factor with a warm white tone is essential.

Frequently Asked Questions (FAQs)

1. What type of ballast is required for this 2D 28w 2-pin tube?
This lamp is designed for fixtures with a magnetic ballast typically used in 2-pin 2D fittings. It is not compatible with electronic ballasts designed for 4-pin versions or direct mains voltage connection.

No, this 2D 28w fluorescent tube is non-dimmable. Using it with a dimmer switch may cause flickering, reduced lamp life, or damage to the lamp and ballast.

3. What is the difference between 3500K and 4000K color temperatures?
3500K produces a warm white light with softer, more inviting tones, ideal for residential and hospitality settings. 4000K produces a cooler, crisper white light often preferred for task-oriented and commercial environments.

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 2-pin 2D tubes.

5. Where is this lamp best applied?
Its larger square size and warm white output make it ideal for flush-mounted ceiling fittings in living rooms and kitchens, commercial light boxes, retail display areas, hospitality venues, and residential spaces where broader light coverage with a comfortable, inviting ambiance is desired.
