'Warm White' (2700K – 3000K)
This white gives off yellowish light that helps enrich the warm colours in your store, like wood. They are more suitable for clothing stores and is known to help people relax. "Warm white" is the same colour temperature as the standard inefficient incandescent bulbs.
'Cool White' (4000K)
'Cool White' looks crisper under higher colour temperatures and appears more 'normal' in high lighting level situations. As a matter of fact, 'cool white' gives off a bluer light that improves our ability to see contrasts, making it ideal for work areas such as kitchens, laundries, workshops and offices.
Daylight (6000K and above)
Daylight lamps appear to be cooler or 'bluer' than 'normal' lamps and are generally used for special applications only. These might be areas where high quality colour rendition is required where they may be mixed with a warm white lamp for this purpose. They may be used on their own such as in shop lighting when special effects are required or a 'cool' appearance is required in places of entertainment.
