You might be used to choosing light bulbs by their wattage. After all, the higher the wattage, the brighter the light – right?
Well, not exactly if you’re in the market for energy-saving LED lights. In fact, it’s the colour temperatures of LED lights that you need to look out for, which is also known as the ‘Kelvin’ or the value of a bulb.
LED colour temperature is measured in ‘Kelvins’ (K), and it’s Kelvins that determine what shade of white light your bulbs beams, ranging from ‘warmer’ colours reminiscent of traditional incandescent bulbs, to ‘cooler’ colours that are whiter in tone.
There are 4 main LED light colours to choose from, each with a different kelvin rating:
• Very warm white (under 2700K)
• Warm white (2700-3200K)
• Daylight (4000K-5000K)
• Cool white (5500K-6500K)
