LED GLS bulb Spectrum E27 11.5W 230V Cool White (model WOJ13909_220ST)

Spectrum LED GLS E27 11.5W Cool White is a general-purpose LED replacement bulb designed for standard E27 screw fittings. With a classic GLS shape and an 11.5W rating for 230V mains, this bulb delivers cool white illumination suitable for residential and light-commercial spaces where clear, neutral task lighting is required. The lamp preserves the familiar appearance of incandescent GLS bulbs while offering the energy efficiency and longer life of LED technology.

Advantages

The LED design reduces energy consumption compared with traditional incandescent lamps and produces less heat during operation. Its cool white color temperature provides crisp, neutral light that enhances visibility for tasks and everyday activities. The bulb’s standard E27 base and GLS form factor ensure compatibility with a wide range of lamps and ceiling fixtures, making replacement straightforward without modifying existing fittings.

Suitable for

• General room lighting in living rooms, kitchens and bedrooms
• Desk and task lamps requiring clear, cool white light
• Ceiling fixtures and pendant lamps with E27 fittings
• Offices and workspaces where neutral color rendering is needed

Key specifications

• Rated power: 11.5 W
• Supply voltage: 230 V AC
• Light color: Cool White (neutral to cool color temperature)
• Base type: E27 screw
• Bulb shape: GLS (standard pear-shaped lamp)
• Suitable for use in open luminaires and enclosed fixtures where LED bulbs are supported (check fixture heat dissipation)

How to use

Install the bulb into a compatible E27 socket by ensuring power to the fixture is switched off, screwing the bulb clockwise into the fitting until secure, and restoring power. Use in fixtures rated for 230 V mains and avoid excessive mechanical force when tightening. For best performance, allow a short warm-up period after switching on; the bulb reaches stable output immediately but may take seconds to stabilize color and brightness.

Usage recommendations

For safe operation, use the bulb within specified mains voltage and avoid exposure to moisture unless the fixture is rated for damp locations. If used in enclosed fittings, verify adequate ventilation to prevent overheating. Replace with an identical base and wattage-equivalent LED bulb when performing maintenance.
