For incandescents, there is an accepted correlation between the brightness and the watts, but for LEDs, watts aren't a great predictor of how bright the lightbulb will be. (The point, after all, is that they draw less energy.)
For example, an LED lightbulb with similar brightness to a 60W incandescent is only 8 to 12 watts.
Instead, another kind of measurement should be used: lumens.
The lumen (lm) is the actual measurement of brightness supplied by a light bulb, and is the number you ought to look for when searching for LEDs. For reference, here's a graph that reveals the watt-lumen conversion for LEDs and incandescents.
Selecting the most appropriate colour LED
You can always count on incandescents supplying a warm, yellowish color. But LEDs come in a broad variety of shades.
LED lightbulbs are with the capacity of exhibiting an impressive color variety, from purple to red, into a spectrum of yellows and whites as shown off by the Philips Hue. For something similar to the light, however, you're probably looking for the house that incandescents create.
While bulbs labeled as bright white will create a whiter light, closer to sunlight and similar from what you see in retail stores, warm white and soft white will create a yellow colour, close to incandescents.
So, your typical incandescent is somewhere between K. 2,700 and 3,500 If this's the colour you're going for, look for this range while shopping for LED bulbs.
You will pay more for an LED lightbulb
LED bulbs are like hybrid cars: not more expensive to work but upfront that is costly.
Don't expect to save buckets of cash,
when switching to LED bulbs. Think of it as an investment. Fortunately, competition has grown and LED bulbs came down in price, but you should still expect to pay more than an incandescent.
Eventually, the LED lightbulbs will pay off, and in the meantime, you'll enjoy less heat generation, longer bulb life, as well as the option of commanding them.
Bottom line: unless you're replacing many incandescent lightbulbs in a large house, you will not see significant savings in your electricity bill.
Watch out for non-dimmable LEDs
As a result of their circuitry, LEDs are not always compatible with dimming switches that are traditional. In some instances, the switch must be replaced. Other times, you'll pay only a little more for a LED that is compatible.
Most dimmers, which were probably designed to function with incandescents, work by cutting off the number of electricity sent to the bulb. The electricity that was less drawn, the dimmer the light. But with your recently acquired knowledge of LED lingo, you realize that there is no direct correlation between LED brightness and energy drawn.
This guide describes some LEDs buzz when tied to a dimmer, flickr, or will hum.
When searching for LEDs, it helps to know the type of dimming switch you've got, but should youn't understand (or would rather not go through the trouble), only search for LED bulbs compatible with standard incandescent dimmers. To make things more easy for you, we examined a slew of them to learn which LED bulbs work best with dimmers.
