Understanding PL-S 11W 840 Cool White

PL-S lamps are single-ended compact fluorescent lamps commonly used in compact lighting fittings.

The 840 colour code identifies the lamp's light colour:

• 8 – Colour rendering index category of 80–89.

• 40 – 4000K colour temperature.

This makes the 840 Cool White option a useful choice where a neutral white light is preferred over warmer 2700K or 3000K lighting.

Common Applications

PL-S 11W 2-pin lamps are commonly found in compatible:

• Commercial and office lighting fittings

• Wall-mounted lighting fixtures

• Ceiling and bulkhead lights

• Display and cabinet lighting

• General indoor fluorescent lighting installations

Always check the original fitting and lamp requirements before ordering.

Important Compatibility Information

Not all PL-S lamps are interchangeable.

Before purchasing, check the following details on your existing lamp:

1. Wattage: 11W

2. Base: G23 2-pin

3. Lamp type: PL-S

4. Colour temperature: 840 Cool White (4000K)

A 4-pin PL-S lamp uses a different base configuration and is not a direct replacement for a 2-pin G23 lamp.

Also check that your fitting has the correct control gear for the replacement lamp. A matching wattage and base alone do not guarantee compatibility.
