When choosing an LED bulb for your home or office, you first need to be clear about what your requirements are, and then pick the light and color you need. So, what kind of work do you need to consider when choosing an LED bulb? Also want to save electricity and want to be beautiful? How to choose the right LED bulb?
Low wattage, high lumens
The first thing you should consider is how to save electricity and cut electricity bills. If the lumen of the lamp is high, then the light is brighter. Compared to incandescent bulbs, LED bulbs provide a lot of lumens in just a few watts. So, you need to find a low-wattage, high-lumen light bulb, because it saves electricity.
Lifespan
The second, you should consider the life of the LED bulb. Most LED bulbs provide 25,000 to 50,000 hours of light if used for three hours a day.
However, after assembly into a luminaire, it is also related to the life of other electronic components. That is to say, the lifespan of LED lamps is less than 100,000 hours, which may cause problems. It is not necessarily a problem of LED itself. It may be that the components of the power chip, electrolytic capacitors and the like are first out. Then there are a lot of LED manufacturers, and the quality is not good.
Color and color rendering index
The third job is the color of the LED bulb. One advantage of LEDs is that light can be tuned to the full spectrum. LED lights can be red, yellow, green, blue, warm white, and cool white.
The lower the color temperature, the lower the Kelvin, the whiter the white light. If the color temperature is higher, it will be bluish. If you want a warm color, look for an LED of about 2700K. For cool white light, look for 3500K to 4100K bulbs; 5000K to 6500K bulbs look like natural light or daylight.
Another aspect of color is the color rendering index (CRI), which reflects the accuracy of color under light. The higher the color rendering index, the more objects the LED bulb will light up.
Light communication
LED bulbs illuminate in a specific direction. The transmission of light is called the beam angle. The beam views of the LED bulbs on the market are 15, 30, 45, 60 and 100, respectively, while the 120 and 180 are rare. A beam angle of less than 30 can be used as a spotlight with the highest brightness or lumen per watt, making it ideal for shops and local areas where demand is outstanding.
Beam angles greater than 30° are suitable for high power LED lamps such as downlights. They can be placed on the ceiling to illuminate the room. If the ceiling is high (more than 3 meters), a 30-45 degree beam view can be used. If the ceiling is less than 3 meters, then it is best to use a 60-100 degree beam view.
Correct luminaire
LED lights are a little heavier than traditional bulbs, so you should check to see if existing fixtures can support the weight of the LED bulb.
LED bulbs cannot be completely turned off in the fixture because heat reduces the life of the bulb. If you want to use LED bulbs in the wild, then the bulbs should be weatherproof or can accept wet field conditions.
certified product
It is very important that the LED bulb fits into some safety regulations. If the LED bulb fits into the Power Star specification, it will add a lot of points. Because the Power Star certification has high requirements for brightness, color and power usage.
LED lighting products within the scope of CCC certification generally include six types of LED lighting products. Fixed general-purpose LED lamps, such as LED lawn lamps, garden lamps; movable general-purpose LED lamps, such as LED desk lamps; embedded LED lamps, such as LED downlights, ceiling lamps; LED aquarium lamps; LED nightlights installed in power sockets ; embedded LED lamps on the ground.
warranty period
Because LED bulbs are more expensive than traditional bulbs, you should pick a brand that has a manufacturer's warranty. A good LED bulb should have a warranty period of at least three to five years.
