Now's the right time to change to LEDs. These bulbs have made major improvements over the last few years, eventually producing us have comforted with for decades.
Choosing an LED is totally not the same as picking up an incandescent, because there are so many LED varieties. Before you head to the shop, find out what you have to understand about selecting the right LED lightbulbs.
Lumens, not watts
Forget what you understand about incandescents -- your watts aren't any good here.
You're probably accustomed to looking for watts, an indicator of how bright the lightbulb will be, when shopping for lightbulbs. The brightness of LEDs, however, is determined a little otherwise.
Contrary to common belief, wattage isn't an indicator of luminosity, but a measurement of how much energy
the bulb draws. For LEDs, watts are not a great predictor of how bright the bulb will be, although for incandescents, there is an approved correlation between the brightness and the watts drawn. (The purpose, in the end, is they draw less energy.)
For instance, an LED lightbulb with comparable luminosity into a 60W incandescent is just 8 to 12 watts.
But don't trouble doing the math -- there isn't an uniform way to secret incandescent watts to LED watts. Instead, a different type of measurement should be used.
For reference, here's a chart that shows the watt-lumen conversion for incandescents and LEDs.
Choosing the right color LED
You always have the option to count on incandescents providing a warm, yellowish colour. But LEDs come in a wide range of colours.
LED lightbulbs can handle displaying an impressive color range, from purple to red, to a spectrum of whites and yellows as shown off by the Philips Hue. For the dwelling, however, you're likely trying to find something similar to the light that incandescents generate.
The popular shades available for LEDs are "warm white" or "soft white," and "brilliant white."
While lightbulbs labeled as vivid white will create a whiter light, closer to daylight and similar from what you see in retail stores warm white and soft white will create a yellow colour, close to incandescents.
If you want to get technical, light colour (color temperature) is measured in kelvins. The lower the number, the warmer (more yellowish) the light. Your typical incandescent is someplace between 2,700 and 3,500K. Look for this particular variety while shopping for LED lightbulbs for, if this's the color you are going.
You'll pay more for an LED bulb
LED lightbulbs are like hybrid cars: more affordable to operate but costly upfront.
When changing to LED bulbs, do not expect to save buckets of cash. Instead, think of it. Fortunately, competition has increased and LED bulbs have come down in cost, but you still ought to expect to pay more than an incandescent.
Eventually, the LED bulbs will pay off, and in the meantime, you will love even the alternative of commanding them, longer bulb life, and less heat generation.
Bottom line: you will not see considerable savings in your electricity bill unless you are replacing many incandescent bulbs in a big house.
Look out for non-dimmable LEDs
Because of their circuitry, LEDs usually are not always compatible with conventional dimming switches.
