E27 Golf Ball 5.9W LED Bulb - Cool White

This E27 LED bulb takes the small, round golf ball (G45) shape, giving a compact lamp that suits fittings where a full-size GLS bulb would look too large. It draws just 5.9 W yet puts out 806 lumens at 4000K cool white, a crisp, neutral tone that keeps colours looking true. The 150 degree beam angle spreads light broadly rather than directing it, so it fills the space around the fitting evenly. American buyers will recognise the E27 thread as a standard Edison screw, the same medium screw base used on common household lamps.

Being a golf ball form on an E27 screw cap, it drops straight into pendants, multi-arm ceiling fittings, wall lights and shaded table lamps that call for a neater bulb. The cool white 4000K output works well in kitchens, home offices and hallways where a clear, alert light is wanted rather than a soft warm glow, and the Ra 90 colour rendering means food, fabrics and finishes are shown faithfully. It is rated IP20 for dry indoor use only, so keep it to enclosed interior rooms and clear of bathrooms, porches or any exposed outdoor position. The wide 150 degree spread makes it a good general-purpose lamp rather than a tight directional spotlight.

The bulb measures Ø45 by 77 mm and weighs only 20 g, with a plain white finish to the body. It runs on 220 to 240 V AC mains directly through the E27 cap, with no separate driver or transformer required. At 5.9 W it replaces a 60 W traditional bulb while using a fraction of the energy, and its 137 lm/W efficiency and rated 25,000 hour lifespan keep running costs and replacements low. Please note this lamp is non-dimmable, so it should be used on a standard on or off circuit. Niori stocks this lamp alongside other E27 and golf ball shapes in the range for matching multiple fittings.

Product Specification Sheet

Range Datasheet

What fitting does this bulb need?

It has an E27 cap, also called Edison Screw or ES, which is the larger screw thread found on many pendants, ceiling fittings and table lamps. You simply screw it in, with no adaptor needed. American buyers will know E27 as the standard medium Edison screw base.

What old bulb wattage does it replace?

At an actual draw of 5.9 W it gives 806 lumens, roughly the output of a 60 W traditional incandescent bulb. The LED itself only uses 5.9 W, so you keep the brightness while cutting energy use significantly.

Is this a warm or cool light?

It is 4000K cool white, a clear neutral tone that sits between soft warm white and bright daylight. With Ra 90 colour rendering it shows colours accurately, which suits kitchens, offices and task areas rather than cosy living spaces.

Can this bulb be dimmed?

No, this is a non-dimmable bulb and should be used on a standard switched circuit rather than a dimmer. Fitting it to a dimmer may cause flicker or shorten its rated 25,000 hour lifespan.
