Trying to understand the important consideratio ns when choosing your studio light can easily lead you into a lighting melt down. Basically a studio needs at least a space which has the natural light and the best artificial lighting. The artists’ lights play a major role to determining the quality of work you produce to your clients. To cut the story short, there are quite a number of variables you need to know when selecting lights for your studio. They include color temperature, CRI rating, brightness and type. Here is a highlight of these important features.
It is measured in Kelvins and denoted as K. the best color temperature for artists’ lights is 5000K, which gives your studio a nice white light. Color temperature of your light bulbs is equally important as the color of paints. The color of the light illuminating the palette and painting will change the visible hue, chroma and value of your paint. Painting using the incandescent light bulb is not recommended since the light shifts all the colors towards yellow. The color temperature of a light can be determined using the Kelvin scale. A color temperature of 6500K will give you the best light equivalent to natural light.
The light amount emitted by a light bulb is measured in lumens. A typical 32W fluorescent bulb can emit light of up to 2000 lumens. Compact fluorescent light bulbs are the most efficient in emitting light as compared to incandescent bulbs. A 42W fluorescent bulb can emit light as much as a 200W incandescent bulb can emit. If your studio is medium sized, then a lumen range between 7000 and 8000 lumens is the most effective. At least two to three fluorescent light bulbs with 110W to 125W can give you at least 7000 lumens of light.
Color Rendering Index (CRI)
This is a measure of how much effect a light has on the perceived color of a surface or object. The CRI scale ranges from 1 to 100. A higher CRI rating makes colors appear more natural and vibrant while a low rating can completely ruin the hue of colors of objects. A high CRI rating however does not guarantee a perfect color if the color temperature is much higher. For instance, incandescent have CRI rating of 100, but their extreme yellow color changes the appearance of colors on other objects. A fluorescent bulb is therefore best. You should look for one with a CRI value of 80 or higher.
Type of bulb
Bulb type also dictates the type of lights emitted. An incandescent bulb use much energy and produce extreme yellow light not suitable for artists. On the other hand, compact fluorescent bulbs have a wide range of advantages for artistic activities. They have many color temperature ranges, brighter, energy efficient and last longer.
