G45 LED golf ball bulbs – compact and dimmable warm white light.

G45 LED lamps, more commonly known as LED golf ball bulbs, are very small and compact, designed to fit into smaller fixtures and fittings or where a lower level of brightness is preferred over a standard sized LED bulb.

Our LED golf ball bulb is unique. Not only is it dimmable, it has a market-leading Colour Rendering Index (CRI) rating of 97 out of 100, making it one of the only bulbs available that has the required quality of light to match a traditional incandescent lamp.

This 4 watt bulb is a direct replacement for a 25 watt incandescent bulb. Switching to LED golf ball bulbs would use 84% less energy and result in substantial savings on your lighting bills.

This bulb has a colour temperature of 2700k, which is the optimum warm white for replacing existing incandescent and halogen lamps. It is available in three different fittings to suit all applications – E27 (large screw), E14 (small screw) and B22 (bayonet).

LED golf ball bulbs are ideal for places that don’t require too much light such as bedside lamps, table lamps and wall lamps. Because of their size they are also perfect if you have smaller lamps where a larger bulb would show above the short lamp shade.


  • Engineered to have exactly the right amount of lumens to replace a 25w incandescent G45 bulb

  • Smooth dimming with wide range of dimmers

  • Warm White colour temperature and High CRI enables the product to have incredible clarity

  • As quick and easy to install as a 25w incandescent G45

  • Available in E14 (Small Screw) fittings, E27 (Large Screw) fittings and B22 (Bayonet) fittings

  • 88% Energy Saving Potential

If LED lamps are so great, why is there so much terrible LED lighting? Are dull colours just the price you pay for lower bills? The answer to these questions is “Colour Rendering Index”. In most LED lamps it’s simply too low. At Well-lit, all our LED lamps have CRI values of 95 or above. So you can replave your halogen and incandescent lamps without losing quality of light. (And change those poor quality LEDs for something rather better.)
