Technical Specifications

Important Compatibility Information

Circular fluorescent lamps can look very similar while having different diameters, wattages, colour temperatures and base configurations.

For this NZ Lights product, check:

✓ 22W

✓ T9 Circline

✓ G10q

✓ 4-Pin

✓ Daylight

✓ Approx. 208mm outside diameter

✓ Approx. 29mm tube diameter

Do not select a replacement simply because another circular tube is rated at 22W.

The base and physical diameter must also match.

How to Identify the Correct Replacement

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

Look for:

22W

G10q

T9

Daylight

or a manufacturer-specific lamp number.

You should also measure the outside diameter.

For this product:

Outside Diameter: Approx. 208mm

Tube Diameter: Approx. 29mm

If your old lamp's markings are difficult to read, the combination of 22W + G10q + 208mm diameter can be very useful when identifying the correct replacement.

Daylight Light Colour

A Daylight fluorescent lamp produces a brighter and cooler-looking light than Warm White or standard Cool White options.

It is particularly suited to areas where clear, functional illumination is preferred, including:

• Kitchens
• Bathrooms
• Utility areas
• Work spaces
• Offices
• Commercial interiors
• Retail spaces
• Apartment common areas
• General-purpose ceiling lighting

Daylight lighting can be particularly useful in areas where stronger visual clarity is preferred.

If replacing only one lamp in an existing fitting or installation, check the colour marking on the old lamp to maintain a similar appearance.

G10q 4-Pin Base

This product uses a G10q 4-pin base.

Check the connector on your existing circular fluorescent lamp carefully before ordering.

The correct base is just as important as the wattage and outside diameter.

For this lamp, match:

22W • T9 • G10q • 4-Pin • Daylight • 208mm

Do not choose a replacement based only on the circular shape.

How to Measure a Circline Lamp

Measure straight across the complete circular tube from the outer edge on one side to the outer edge on the opposite side.

For this lamp:

Outside Diameter: Approx. 208mm

The fluorescent tube itself is approximately:

29mm diameter

Always check the G10q base as well as the physical diameter before ordering.

Hard-to-Find 22W Circline Replacement

Traditional Circline fluorescent lamps are becoming harder to source as many older fluorescent ranges are phased out.

If your existing fitting is still working correctly, replacing the lamp with the correct 22W G10q T9 Circline tube can allow you to continue using the existing fixture without replacing the complete light fitting.

Keep your old lamp until you have confirmed the wattage, base and physical dimensions of the replacement.

Need Help Finding the Correct Circline Lamp?

If you're unsure whether this 22W G10q T9 Daylight Circline lamp is the correct replacement, send NZ Lights a clear photo of your existing lamp showing the printed markings and connector/base.

If possible, also provide the outside diameter.

We can help identify the correct wattage, base, light colour and physical size required for your fitting.
