If you haven't switched to LED bulbs, now is the time. The reasons why are compelling— they last much longer than incandescent bulbs, provide interesting features and can save you money on your electricity bill.
Buying the right LED is very different from buying incandescent bulbs. Before you go shopping, there are some things you need to know.
Forget what you know about incandescents -- your watts are no good here.
For incandescents, there is an accepted correlation between the watts drawn and the brightness, but for LEDs, a different form of measurement should be used: lumens. The lumen (lm) is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs. An incandescent can draw up to five times as many watts for the same number of lumens. Get a sense of the brightness (in lumens) you need before heading to the store, and throw away your affinity for watts.
LEDs come in a wide range of colors, more than a warm, yellowish hue as incandescents provide.
For the home, you're likely looking for something similar to the light that incandescents produce. The popular colors available for LEDs are "warm white" or "soft white," and "bright white.” Warm white and soft white will produce a yellow hue, close to incandescents, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores. Technically speaking, light color (color temperature) is measured in kelvins. The lower the number, the warmer (yellower) the light. So, your typical incandescent is somewhere between 2,700 and 3,500K. If that's the color you're going for, look for this range while shopping for LED bulbs.
LED bulbs are like hybrid cars: cheaper to operate but pricey upfront.
When switching to LED bulbs, don't expect to save buckets of cash. Instead, think of it as an investment. Luckily, competition has increased and LED bulbs have come down in price. Eventually, the LED bulbs will pay off, and in the meantime, you'll enjoy less heat production, longer bulb life, and even the option of controlling them with your smartphone.
LEDs are not always compatible with traditional dimming switches.
If you'd like your LED to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge (LED-compatible) dimmer. When shopping for LEDs, it helps to know what kind of dimming switch you have, but if you don't know (or would rather not go through the trouble), simply search for LED bulbs compatible with standard incandescent dimmers.
Knowing where it's OK to place an LED will ensure that the bulb won't fizzle ahead of its time.
You probably know that LED bulbs run dramatically cooler than incandescent, but that doesn't mean they don't produce heat. LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. From there, the heat dissipates into the air and the LED bulb stays cool, helping to keep its promise of a very long life. Consider where you'd like to place your LED bulbs. If you have fully or semi-enclosed fixtures you need to light up, look for LEDs that are approved for recessed or enclosed spaces.
In addition to the above-mentioned things, another important factor you should take into consideration before buying a LED bulb is to choose a brand from the market. Generally, buying from a well-reputed brand will be a wise choice, because the well-known brand is more likely to produce quality LED bulbs with excellent performance, which will largely reduce the possibility of product failures. In this regard, we recommend the LED Bulb Expert-WELLMAX to you. The brand provides full range of LED bulbs from 3W to 85W, with an accumulative sales volume up to 1 billion pieces across the globe. It has become the first choice for the global consumers.
