On the other hand, it can cause sleep difficulty by suppressing melatonin production. However, there are some things you might want to consider:īlue tint from higher color temperatures (6000 Kelvin and above/cool white) can increase concentration. Using different color temperatures for different roomsīoth are perfectly valid, as they are a matter of taste and preference.Using uniformed color temperature for the whole household.Regarding color temperature for ambient lighting, there are generally two different approaches: Now, since the aim of general lighting is to produce illumination as natural as possible, CRI above 80 is desired, with 85 to 95 being the ideal one.įirst things first, all color temperatures can have CRI above 80, as we have mentioned those two are on separate things. Color Rendering Index, on the other hand, is the ability to reproduce color in comparison to the natural (or ideal) light source. Color Temperature is a measure of the color pallet of the light source, which are caused by the produced heat (hence, 'temperature'). However, they are actually two different things. The common misconceptions is that Color Rendering Index is similar to Color Temperature. Here are a few things you might want to consider regarding General Lighting: For general lighting, your aim is to create illumination as 'natural' as possible. Hence, for general lighting, soft level of light is commonly desired. On the other hand, over-illumination can cause tiredness and anxiety, not to mention a waste of energy. Studies suggested that correct applications of general lighting can reduce stress because general lighting can allow your pupil to dilate by softly illuminating the curves of your face. They are also often referred as mood lighting because it will set up the overall mood of a room. General lighting is the most common of the three types and can come in many different types of fixtures, which we will touch briefly below. General Lighting also often called ambient lighting, because they provide 'ambiance' by illuminating an area thoroughly. Without further ado, we will begin with the first type: we will do an in-depth discussion for each type, and how their differences might affect your applications as well as purchase decisions. Therefore, understanding the difference between three types is really important. The different types can determine many factors from choices of bulbs, placements, fixture designs, wattage requirements, and many others. For lighting applications, professionals generally categorized them into three groups: general, task, and accent lighting.
