How many Alchemy sinks does it take to change a light bulb?
If you want your sink to look more bight and vivid, and you have a fluorescent, incandescent or older LED bulb lighting it, you?re not getting the spectrum of color that you would see with a higher CRI bulb, whether it?s a halogen spot or a high CRI LED. So the answer is it could take just one sink.
The coloring in Alchemy sinks is truly unique. To bring out all the subtle shifting tones of gold and blue that contribute to creating the vivid reds, greens and violets, you need a light source that has a high color rendition index or CRI. The highest CRI light source I know of is the sun because it has about all the visible (and some invisible) wavelengths of light that exist. White light is a mix of a spectrum of colors and the reason objects appear to have a specific color is that when they are lit by white light, they selectively reflect the color band from that spectrum that you see, and then absorb or scatter the rest.
Light bulbs don?t have all the bands of color that the sun does, but they usually have enough that an object will reflect at least one color. Different light sources have different amounts of color bands in them. More bands mean a light source can bring more of the visible spectrum to your eyes, and the more likely that source will have the subtle color variations that an object may have. Some light sources such as Sodium Vapor only have 3 bands of color, none of them red. If you?ve ever seen a red car parked under a sodium lamp at night (old street lights), the car would simply look gray because there is no red in the light for it to reflect. As you can see in the graphic, fluorescent similarly has just 3 strong bands, leaving much of the spectrum of potentially visible color invisible.
Not that anyone would light their bathrooms with sodium vapor lights, but fluorescents have limited bands of color as well. They do have all the basic colors but not many of the subtle shades and as a result, objects with subtle color shading in them lose detail when lit this way. Tungsten lights are good and halogen are even better. Early LEDs didn?t have many component colors to mix together to make white light so their CRI was pretty low and even though the light?s color looked white, colorful objects looked kind of flat when lit by early LED bulbs. High CRI LED bulbs haven?t become the norm yet, but they are available. Look for a CRI of 90+.*
I also prefer spot lights that focus the light on the sink because, well, we like the sinks to be the star of the show, and when you have a star you put a spotlight on them. It helps make them glow, and it works like that on the sinks too.
Lighting Alchemy sinks with a light source that has a lot of color in it will make the sinks sing. You?ll see colors you didn?t know existed and you?ll see them change as you approach them or change your gaze. We sometimes get comments that our sinks don?t look as good as they do in the pictures. The pictures are not retouched, it?s just the lighting that?s probably better. But that?s easily fixed in your own home by changing a light bulb.
