Lumens: Lumens indicate how bright a bulb is while watts indicate the amount of energy use to power it. So, if you’re using an LED in your art room, for example, consider one with a high CRI. Reds will appear red and blues will appear blues under lights with high CRI. The Label: LED packaging is required to include information about brightness, light color, energy use, estimated energy costs, and expected life.Ĭolor: The Color Rendering Index (CRI) is the measurement of how well a source of light renders color. "Daylight" LEDs may have 5000 K, but also tend to be on the bluer side of the spectrum.
Warm yellow light is around 2700 K, while bright white lights are about 3000 K. What to Look for in LED Light BulbsĬolor Temperature: The lighting color of LEDs is usually measured in Kelvin (K).

If you have a house full of incandescent bulbs to replace, the Philips 455576 60 watt ( view at Amazon) or GE Lighting 32279 LED Bright Stik ( view at Amazon) are compatible with most lamps and fixtures and won’t break the bank. Here are some options that received glowing remarks in our research. That means that they can suppress melatonin-a hormone that facilitates sleep-so if you're concerned you may want to consider avoiding very bright LED light too close to bed time, or looking for LED bulbs on the warmer range of the color spectrum. Some LEDs (particularly those used in screens) do emit more blue light than other bulb types. That means you’ll also save money compared to other bulbs because you won’t have to buy them as often, and you’ll have fewer bulbs to dispose of which makes Mother Earth happy. Most manufacturers promise their bulbs will last 20,000 to 50,000 hours, and offer warranties to back these claims. Switching to LED bulbs will reduce your electric bill and lighten your carbon footprint. LEDs are also a little more efficient than Compact Florescent Lights (CFLs), but unlike CFLs, contain no mercury. However, they use 75 to 80 percent less energy than a traditional incandescent bulb. They may cost slightly more upfront than other light bulbs.
They come in multiple shapes, color, and temperature options. They can be used indoors, outdoors, and can even be solar-powered. LED ( Light-Emitting Diode) bulbs aren’t just for specialty lamps anymore.
