The A++ energy efficient Calex 2.5W light bulb will provide you with warm white illumination. Complete with a life span of 20,000 hours.
The size and shape is similar to that of a halogen bulb.
LEDs use around 85% less energy than incandescent bulbs and will last an average of 20,000 hours.
- Energy Rating
Graded on performance, from A+++ to G, with A+++ being the highest rating. Higher ratings mean better energy efficiency
- Fitting type
This indicates the cap or base of the bulb, Examples: BC-B22 = bayonet cap/ ES-E27 = edison screw/ SBC-B15 = small BC/ SES-E14 = small ES
This shows the approximate colour of the light output of the bulb, shown in degrees Kelvin (K). The lower the number the warmer the light, the higher the number the whiter the light.
- Lifetime (Hours)
Shown in hours, this is based on an average use of 3 hours illumination per day
- Lightbulb Shape
- Lightbulb Type
- Lightbulb Wattage
Estimate of apparent amount of light the bulb will produce, measured in lumens (lm). The higher the number the brighter the light output.

Brand information & size guide
|Traditional Wattage||LED Equivalent||Lumens|
Please note: The table above is a guide to show you the equivalent bulb wattage across traditional bulbs and LEDs.
A bulb's wattage tells us how much energy it uses, rather than the amount of light it generates (lumens). Lumens (lm) are a measure of the total output of visible light from a lamp or light source. The higher the lumen the “brighter” the lamp will appear. To make comparing bulbs easy, it’s best to look for the light output (lumen).
