LED light globes – the perfect energy saving light source.
Retrofit LED globes are available for most commonly available light fittings and applications. Whilst the “wattage” is still used to identify the globe size, it is the lumen output which you should look at.
Colour Temperature is used to identify the “colour” of the light, 3000K is warmer (like the older incandescent globes), 4000K and 5000K are “cooler”.
For good colour rendition look for globes with a CRI of Ra80 or above.
