The GR8 2D 2-Pin 28W Cool White Fluorescent Lamp is a compact square-shaped replacement lamp designed for compatible 2D fluorescent fittings using a GR8 2-pin base.

Producing approximately 2050 lumens with a clear 4000K Cool White colour temperature, this 28W 2D lamp provides bright, broad and even illumination while maintaining the distinctive flat design used in many traditional 2D light fittings.

It is commonly used in compatible bulkhead lights, ceiling fittings, corridors, stairwells, bathrooms, apartment common areas, security lighting and commercial lighting installations.

This lamp is particularly useful as a replacement for older or difficult-to-find 28W GR8 2-pin 4000K 2D fluorescent lamps, provided the original lamp has the same wattage, base, pin configuration, colour temperature and compatible control gear.

What to Match on Your Existing Lamp

28W

GR8

2-Pin

4000K / Cool White

The lamp should also be physically suitable for your existing fitting.

Important: Manufacturer names and references are provided as a replacement guide only. Always confirm the wattage, base, pin configuration, colour temperature and dimensions of your existing lamp before ordering.

Common Applications

The GR8 2D 28W 2-pin fluorescent lamp is commonly used in compatible:

• Bulkhead lights

• Bathroom lighting
• Hallways and corridors
• Stairwell lighting
• Apartment and body-corporate common areas
• Security lighting

How to Identify the Correct Replacement

Before ordering, check the markings printed on your existing 2D fluorescent lamp.

For this product, you should be looking for:

28W + GR8 + 2-Pin + 4000K / Cool White

Your existing lamp may use slightly different terminology depending on the manufacturer.

For example, you may see:

28W 2D

28W GR8

28W/2P

28W Cool White

4000K

The manufacturer may also use its own product or catalogue number.

If the old lamp has no readable markings, check the number of pins, base configuration and physical dimensions before ordering.

GR8 2-Pin – Important Compatibility Information

This product uses a GR8 2-pin base.

Please check the base of your existing lamp carefully before ordering.

A similar-looking 4-pin 2D fluorescent lamp is not automatically interchangeable with this GR8 2-pin lamp, even if it has the same 28W wattage and similar square shape.

For this product, check:

✓ 28W

✓ GR8

✓ 2-Pin

✓ 4000K Cool White

Do not select a replacement based solely on the shape of the lamp.
