The 28W 2D Fluorescent Bulb 4 Pin produces bright and consistent illumination with a Cool White 7000K colour temperature. Its crisp lighting effect is particularly useful in rooms and commercial areas where clear visibility and functional everyday lighting are required.

With an output of approximately 2250 lumens, this compact fluorescent lamp delivers strong general-purpose brightness while consuming 28 watts. It is suitable for compatible light fittings installed in bathrooms, kitchens, corridors, stairwells, utility rooms, offices and communal areas.

The distinctive 2D shape distributes illumination effectively throughout a suitable fitting. This makes the 28W 2D Fluorescent Bulb 4 Pin a practical replacement for an existing lamp with matching wattage, dimensions, base type and electrical requirements.

A GR10Q 4-pin cap is positioned at the centre of the lamp. Before ordering, safely remove the existing bulb and confirm that its base also contains four connecting pins. The cap type and pin arrangement must match the fixture to ensure correct installation and operation.

A GR10Q 4-pin bulb must not be confused with a GR8 2-pin lamp. Although both versions can have a similar 2D shape, their bases and electrical control requirements are different. The two lamp types are therefore not directly interchangeable.

The 28W 2D Fluorescent Bulb 4 Pin is designed to operate with compatible fluorescent control gear. Existing fixtures may contain electronic ballasts or emergency-lighting components, so the fitting and ballast specifications should always be checked before installation.

The Cool White 7000K output creates a clean, bright and highly functional lighting effect rather than a warm decorative glow. It is well suited to bathrooms, washrooms, kitchens, storage rooms, offices and other locations where strong visibility is preferred.

Its compact and relatively flat profile allows the bulb to fit inside many compatible round, square and rectangular bulkhead fixtures. The 2D format is particularly useful in fittings where a conventional household bulb or long fluorescent tube cannot be installed.

The 28W 2D Fluorescent Bulb 4 Pin offers a rated lifespan of up to 10,000 hours under appropriate operating conditions. Its dependable service life can help reduce maintenance requirements and the inconvenience associated with frequent lamp replacements.

This compact fluorescent lamp can provide a suitable replacement option for compatible domestic, communal and commercial installations. Homeowners, landlords, facility managers and maintenance teams should compare its specifications with the existing lamp before ordering.

For safe replacement, switch off the electricity supply and allow the existing lamp to cool completely. Hold the lamp by its plastic base instead of pulling on the glass tubes. Carefully align all four pins with the fitting and avoid applying excessive pressure.
