Here are a few that you’ll most likely find at a home improvement store:Ģ700K: These bulbs will be labeled “soft white,” and will cast a gentle warm glow that’s good for the bedroom, as well as table and floor lamps.ģ000K: “Bright White” bulbs have a more neutral glow, being neither warm nor cool.ĥ000K: Lights that are 5000K and higher will typically have a “daylight” label, and edge towards the bluer part of the spectrum. However, LED makers now offer LED bulbs that emit different color temperatures, measured in Kelvin.
When they first came out, LED bulbs emitted a bluish light that many found harsh compared to the “warmer” light cast by traditional bulbs. In addition, GE ‘s Reveal lineup of color-enhancing lightbulbs (a coating filters out yellow tones to enhance colors lit by the bulb) with LED replacements equivalent to 40-watt and 60-watt A19 bulbs and to a 65-watt BR30 bulb. GE, Philips, Sylvania, Cree and other brands (including IKEA) all offer LED bulbs that output the most popular "soft white" light, at retailers including Home Depot, Target and Walmart. For example, a 4-pack of Philips 60-watt-equivalent soft white LED bulbs costs about $12 on Amazon, a cost of $3 per bulb. Initially, LED bulbs cost a lot more than old-fashioned incandescent bulbs, but now have dropped in price. LED bulbs will continue to light up even after their rated lifetimes expire however, brightness may drop or the color cast of the light may change. Philips' equivalent LED bulb has a rated lifetime of 10,000 hours or 9.13 years. GE's equivalent LED bulb has a rated lifetime of 15,000 hours or 13.7 years. Under the same conditions, an old-fashioned lightbulb may work for only about a year before burning out. And a 65-watt BR30 (floodlight) replacement LED bulb consumes only 10 to 13 watts.Īn LED bulb's lifespan, estimated based on three hours of use per day, is at least a decade, manufacturers say.
A 40-watt equivalent LED bulb consumes only 6 to 8.5 watts. The LED equivalent of a 60-watt A19 bulb consumes only between 9 and 12 watts, and provides about the same light output, measured in lumens. Traditional bulbs for table and floor lamps are known by their lighting industry style name "A19,"while floodlight bulbs made for track lights and in-ceiling fixtures are dubbed "BR30." Your best long-term alternative to either style is extremely energy-efficient LED technology.
