Older 2D fluorescent lamps are available in several colour temperatures, and manufacturer colour codes may differ from the specifications of this particular NZ Lights product.
For this reason, do not select a replacement based only on a manufacturer name or similar-looking 2D shape.
For this product, the specifications that should be matched are:
28W • GR8 • 2-Pin • 3500K
If your existing lamp is Philips, OSRAM, GE, Sylvania, Crompton or another brand, check the actual markings printed on the lamp before ordering.
Important: Manufacturer names are provided as a replacement guide only. Always confirm the wattage, GR8 base, 2-pin configuration, colour temperature and physical dimensions of your existing lamp.
The GR8 2D 28W 2-pin fluorescent lamp is commonly used in compatible:
Bulkhead lights
Ceiling fittings
Bathroom lighting
Hallways and corridors
Stairwell lighting
Apartment and body-corporate common areas
Commercial buildings
Hospitality environments
Utility areas
Public buildings
Wall-mounted fittings
Enclosed exterior fittings
The compact square design provides broad illumination without requiring the length of a conventional linear fluorescent tube.
This makes 2D lamps particularly useful in shallow wall and ceiling fittings where space is limited.
Before ordering, check the markings printed on your existing 2D fluorescent lamp.
For this product, you should be looking for:
28W + GR8 + 2-Pin + 3500K
Your existing lamp may use terminology such as:
28W 2D
28W GR8
28W/2P
3500K
or a manufacturer-specific catalogue or model number.
If the markings are difficult to read, check the number of pins and physical dimensions of your existing lamp.
This product uses a GR8 2-pin base.
Please check the base of your existing lamp carefully before ordering.
A similar-looking GR10q 4-pin 2D fluorescent lamp is not interchangeable with this GR8 2-pin lamp simply because it has the same wattage or similar square shape.
For this product, check:
✓ 28W
✓ GR8
✓ 2-Pin
✓ 3500K Warm White
✓ Compatible physical dimensions
Do not choose a replacement based solely on appearance.
The 3500K Warm White colour provides a balanced light appearance between traditional warmer 2700K lighting and cooler 4000K lighting.
It is particularly suitable for:
Hallways
Bathrooms
Apartment common areas
Hospitality environments
Commercial interiors
Reception areas
Corridors
General-purpose ceiling lighting
3500K can be a useful choice where you want a comfortable light appearance without the stronger yellow tone associated with 2700K lamps.
If maintaining the same light appearance as your existing installation is important, confirm that the old lamp is also 3500K before ordering.
If you're unsure whether this 28W GR8 2-pin 3500K lamp is the correct replacement, send NZ Lights a clear photo of your existing lamp showing the printed markings and base.
We can help identify the correct wattage, pin configuration, base, colour temperature and suitable replacement for your fitting.
