Choosing the Right Light Bulbs

We have a wide range of light bulbs available in a selection of different sizes and shapes. When choosing your light bulb, the first thing you need to find out is what cap fitting you require. The cap fitting requirement is listed in each of our descriptions when buying a light. The reference for the cap fitting you need is normally a letter and a number for example; E27.

 

Once you have identified what cap fitting you require you then have the choice of what light bulb technology you want to use. The three main technologies that light bulbs use are Halogen, Energy saver (CFL) and LED. The traditional incandescent lightbulb technology was phased out in 2011 due to its poor energy efficiency. The majority of the lights bulbs we now supply are the LED variety.

 

LED’s

LEDs (light-emitting diodes) differ from conventional light sources as they last much longer and emit very little heat which results in consuming less energy to run. LEDs are highly durable as they do not feature fragile parts such as glass tubes or filaments. They are also safer because they do not contain any mercury or lead. Although the up-front cost of LEDs can seem more expensive than other options, the life span and energy efficiency of the LED bulbs means that the annual running cost are much lower. LED bulbs use up to 90% less energy than a traditional incandescent and should last up to 25 years* (*based on an average power usage of 3 hours per day).  If you have any questions about LED’s then our blog ‘LED Lighting – Your Questions Answered’ has lots of useful information. https://www.sherwoodlighting.co.uk/led-lighting-your-questions-answered

 

Colour and Brightness

After selecting which light bulb technology you want to use you then need to decided what brightness and colour you require. Traditional incandescent technology measured brightness in watts which is actually a measure of power. As today’s bulbs are more energy efficient measuring brightness in watts is no longer relevant so instead a lumens measurement is now used. The higher the number of lumens the brighter the light. In the description for each of the bulbs we supply you’ll see a lumen output number. The colour of light is measured on the kelvin scale which is actually a measure of temperature. As most of us are more familiar with the traditional warm yellow light of an incandescent bulb this has a kelvin measurement reference point of 2700K. The colour of the midday sun is classed as 5000K and the colour of a clear blue sky is classed as 10,000K. You’ll see a colour temperature figure in the description for each of our bulbs.

 

Bulb Shape

Once you’ve decided what brightness and colour of bulb you want you now need to select what shape you need. We stock a wide selection of shapes as this is an important finishing detail for your light fitting. For example, if you have a chandelier fitting that has exposed bulbs using anything other than a candle shaped bulb could look a little odd. Exposed globe bulbs are also very popular at the moment and can look great hung together in a group without a lamp shade. If you want to conceal the bulb within a fitting or shade you’ll need to check the measurements of the size of the bulb you require.
