It’s a common mistake people make when saving power making their otherwise beautiful lights look a little naff! Different energy saving bulbs are often different colours. The difference between one manufacturers’ WARM white and another isn’t too great, but the difference between Cool White and Warm white is noticable. When you have multiple bulbs on one light-fitting it can look really bad! Just a quick check of the label on the bulb would have probably prevented this mishap.
The picture (right) really highlights the difference between COOL white and WARM white for CFLs. If I can get hold of some, I’ll try to show the differences between LEDs later this week!
Lots of experts say that you should use “warm” white in any lounge setting and cool light for ‘task’ lighting. Let us know your opinions in the comments below.
