Your current bulb may be using a lot of electricity unnecessarily – you can now easily switch to an LED bulb, which will not only save you money and electricity but as it is instant start and very bright you won’t even realise you’ve switched!  As the chart above shows, the most common chosen replacement for a large screw-in bulb is a 3w LED candle with bayonet cap.  These LED candle bulbs use only 3w of electricity, they are instant start – there is no warm up time at all – and are the same shape as the bulbs they replace.  If you prefer to completely hide your energy saving credentials, we have a 2.9w Omni LED candle, which has a much smaller white base and looks so much like the candle you are replacing, you won’t remember they are low energy until you see how low your electricity bill has become.

Need Dimmable?

If you have a dimmer switch, you need to use a low energy bulb that says it is dimmable.  Not a problem, we have a dimmable candle bulbs such as the 28w dimmable halogen candle with bayonet cap.

More light?

If you want more light, maybe to replace a 60w or higher incandescent candle bulb then we recommend an  11w CFL candle bulb with bayonet cap. This is because they produce the most amount of light whilst still being a good energy saving alternative – CFL (compact fluorescent) bulbs are a tried and tested low energy technology.  If you want a lot of light and have a dimmer switch on the circuit then you have two options.  The first is to replace the dimmer switch for a standard switch – if you want a lot of light then you may not really use the dimmer switch anyway.  The second option is to use a 42w halogen candle with bayonet cap. These halogen bulbs save 30% energy versus the 60w bulb it replaces and they are completely dimmable, just like an incandescent bulb.


If you prefer a sparkly candle bulb instead of a white finish then that is also available in the most energy saving option – LED.   The 5.5w dimmable candle bulb is a great all-rounder for compatibility with dimmers and switches and is a very bright, powerful option.  Please be aware of the physical size though as they are slightly larger in diameter compared to some other bulbs.  See the full range of candle bulbs here »

Bayonet Cap

The standard bayonet cap. which is a very common light bulb cap in the UK can also be known or described as ‘BC’ (bayonet cap), or B22.  This is because they are 22mm in diameter across the base (not including the pins, which would make them roughly 27mm).  For the full range of bayonet bulbs available, please see the Replacement Bayonet Bulbs category.
