What is the difference between Warm White and Cool White?
Warm White has a pleasant incandescent tone to the light whereas Cool White is a plain paper White.
The human eye naturally doesn't see Warm White quite as bright as Cool White.
In real terms of Warm White bulb has about 90% of the lumens efficiency of a Cool White unit.
The bad news ends there for Warm White bulbs.
Over the years we've seen a slow transition towards Warm White mainly due to the fact that Cool White got itself a black eye from the early LEDs going blue tinged.
In short - ladies far prefer Warm White to Cool White.
The men prefer Cool White as it is a slightly brighter work light.
