Aurelien David, chief scientist at Soraa, a high-end lighting company founded by the Nobel Prize-winning inventor of the blue light LED, shares lighting guidelines to help enhance the environment and overall well-being.
Go LED
LEDs have surpassed other efficient technologies (such as fluorescent) on every front including energy consumption, quality and reliability, and affordability. They are available in most form factors, from traditional screw-in bulbs to fluorescent-tube-shape retrofits.
Look For Color
The color of the light can be observed by shining it on a white wall. It varies from a cold, sun-like emission called “cool white,” to a warmer shade called “warm white.”
Cool white bulbs can be more efficient, but the light may feel too harsh for domestic use. Look for bulbs labeled 2,700K (they mimic standard incandescent bulbs), or 3,000K (which render a slightly brighter white, like halogen bulbs).
Numbers Game
A bad light bulb can make objects look weird by distorting colors. Luckily, the best LEDs avoid this unpleasant effect. This is indicated by the Color Rendering Index (CRI) often shown on the label, in general, the higher the better.
Most LEDs have a CRI of 80. This means they show decent colors, but make warm colors—including red, orange, skin tones—look dull. Choose bulbs with a CRI of 90 or even 95. High-CRI bulbs are recommended for areas where you will be spending a lot of time such as living room and bedrooms. Keep lower-CRI bulbs for areas where color is less crucial, like the outdoors or the garage.
Brighten up any room with these eco-friendly lighting options.
