Description

This E27 LED bulb gives a soft, low-level glow rather than bright general light, drawing 4W and putting out 200 lumens at a super warm 1800K. The E27 cap is the standard Edison Screw fitting (ES), so it twists straight into common screw-cap holders. For anyone shopping in US terms, the E27 is the medium screw base used on everyday light bulbs there. The ST64 form is a rounded household shape with a gentle amber tone, and the colour rendering sits at Ra 80, so colours read naturally under its warm cast.

At 1800K and 200 lumens, this is a mood and accent bulb rather than a primary room light. It suits exposed pendants, bedside and table lamps, hallway fittings and bar or restaurant-style settings where a relaxed, candle-warm atmosphere matters more than brightness. The light is best thought of as a pool of warm glow close to the fitting, so it works well in clusters or alongside other lamps rather than as the single source for a large space. Because it is rated IP20, keep it to dry indoor positions and clear of bathrooms, porches or any outdoor location.

The bulb runs on 220-240V AC mains directly through its E27 base, with no separate driver to specify, and measures Ø64 by 142 mm at 86 g. Efficiency is 50 lm/W and the rated lifespan is 25,000 hours, so it can stay in service for years in everyday use. It is non-dimmable, so pair it with a standard on/off switch rather than a dimmer circuit. The amber finish and ST64 shape are made to be on show in open fittings, giving a decorative look as well as a warm light.

Frequently Asked

Which fitting does this bulb need?

It uses an E27 cap, the standard Edison Screw (ES) base, so it twists into any common screw-cap holder. In US terms this is the medium screw base found on everyday bulbs. The ST64 shape measures Ø64 by 142 mm, so check your fitting and shade have room for it.

What sort of light does it give?

It produces a super warm 1800K glow at 200 lumens, which is a soft, candle-like accent light rather than bright room lighting. The Ra 80 colour rendering keeps tones looking natural. It is well suited to mood, decorative and atmospheric settings.

Is this bulb dimmable?

No, this is a non-dimmable bulb, so it should be used with a standard on/off switch rather than a dimmer circuit. Fitting it to a dimmer can cause flicker or shorten its life. Its 1800K output already gives a low, warm light without any dimming.

Can it be used outdoors or in a bathroom?

No, it is rated IP20 for dry indoor use only, so keep it out of bathrooms, porches and any outdoor or damp location. It is intended for indoor pendants, table lamps and similar fittings. For wet or exposed areas you would need a fitting and lamp with a higher IP rating.
