Opal LED Golf Ball Bulb E27 G45 3.4W 470lm Warm White

This is a small opal LED golf ball bulb with an E27 screw cap, the large Edison screw that so many table lamps, floor lamps and pendants take. The rounded opal plastic shade sits on a pale body above a silver-coloured cap, and the whole bulb is 7.9cm long and 4.5cm across, so it slips into compact shades and open lampholders where a full-size bulb would look bulky. It draws 3.4W and gives 470lm of warm white light at 3000K. It is rated IP20, which settles where it belongs: in indoor lamps and ceiling lights around the home.

We suggest it for living rooms, bedrooms, hallways and dining areas, anywhere a soft, homely glow suits better than a stark white. The opal shade spreads the light evenly and hides the LEDs inside, which matters in a bare pendant or a lamp with an open top, where a clear bulb can glare. At 3000K the tone is a true warm white, the cosy colour most people want in a room where they relax, and it sits comfortably beside other warm white bulbs in the same space. Because it draws so little power, it is a sensible choice for lights left on through long evenings, such as a hallway pendant or a bedside lamp.

The bulb runs on standard mains at 220-240V, 50/60Hz, and carries an energy class of D. It is not dimmable, so give it a lamp or ceiling light on an ordinary switch; for a dimmer circuit we would choose a dimmable bulb instead. Its packed weight is 0.044KG. For care, wipe the opal shade now and then with a soft dry cloth while the bulb is switched off and cool, which keeps the light clear and even. Before you order, check that your fitting takes an E27 cap and has room for a bulb 7.9cm long.
