Convert lumens to watts
Lumen is the term used to describe the total amount of light emitted by a light source, while wattage merely indicates the amount of energy it uses. As lighting becomes more and more energy-efficient, the same number of lumens is being achieved with lower and lower wattages. That's why, when you replace an incandescent bulb with an LED one, for instance, you should compare the number of lumens rather than the wattage to ensure the brightness is the same. The table below clearly shows the number of lumens that are generated by different types of bulbs at various wattages.
The colour temperature of a light is also important when it comes to choosing the perfect lighting solution for your situation. The colour temperature indicates the colour of the light and is measured in Kelvin. The lower the number of degrees in Kelvin the warmer the light colour. The most common colour temperatures are:
- 2700K = Very warm white light. Provides a relaxed and intimate atmosphere that's perfect for home environments.
- 3000K = Warm white light. Pleasant on the eyes and perfect for general lighting applications.
- 4000K = Cool white light. A stimulating colour temperature that promotes alertness making it perfect for environments like offices and classrooms.
- 6500K = Daylight. This colour temperature is ideal wherever bright light is required and is perfect for environments like laboratories and warehouses.
