How to find out the quality of led lights? When you're looking for the ideal LED bulb for your home or for your office, it's important to first define what your requirements are, and then choose the light and color you need. Or you may just want to find a replacement for a regular 60-watt incandescent bulb. So, what are the things to consider when choosing an LED bulb? How do you choose the right LED bulb?
Top 7 directions to decide how to find out the quality of LED lights!
Low Wattage, High Lumens
The first thing you should consider is how to save energy and reduce your electric bill. If the lumens of the lamp are high, then the light is also brighter. LED bulbs provide a lot of lumens for just a few watts compared to incandescent bulbs. So, you need to find a low wattage, high lumen bulb because it will save on your electric bill.
On average, a 12w LED bulb can provide the same amount of light as a 60 watts incandescent bulb. This means you can save a lot of energy and therefore save money on your electricity bill.
The second thing you should consider is the life span of the LED bulb. Most LED bulbs can provide 25,000 to 50,000 hours of light if used three hours a day for a year.
Color & CRI (Color Rendering Index)
The third thing you should consider is the color of the LED bulb. one of the benefits of LEDs is that the 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, i.e., the lower the Kelvin, the more yellow the white light will appear. If the color temperature is higher, it will appear bluish. If you want warm colors, look for LEDs that are about 2700K. At 3000K, the light is more like a halogen lamp. For cooler white colors, look for bulbs from 3500K to 4100K. 5000K to 6500K bulbs mimic natural light or daylight.
Another aspect of color is the color rendering index (CRI), which reflects how accurate the color is in the light. The higher the color rendering index, the more objects the LED bulb will light up.
Diffusion of Light
LED bulbs emit light in a specific direction. So it is important to find out the angle at which the LED bulb propagates. The propagation of light is known as beam angle. The beam angles of LED bulbs available in the market are 15°, 30°, 45°, 60° and 100°, while 120° and 180° are rare. Those with a beam angle less than 30° are available as spotlights, and their brightness or lumens per watt is the highest. Most of them have a wattage less than 5 and are especially suitable for stores and places where specific areas need to be highlighted.
Beam angles greater than 30° are suitable for high power LED lights such as downlights. They can be placed on the ceiling to illuminate a room, usually with a power rating of more than 5W, and multiple such downlights can be used to illuminate the room.
If the ceiling is very high (over 3 meters), a beam angle of 30-45 degrees is fine. If the ceiling is below 3 meters, then a beam angle of 60-100 degrees is preferable.
The beam angle can be increased by placing reflectors and diffusers, but the problem is that if the beam angle increases, the lumens (or brightness) will decrease.
The Proper Light Fixture
LED lights are a little heavier than traditional bulbs, so you should check to see if your existing fixtures can support the weight of LED bulbs. And since these bulbs are a little longer, it’s possible that the lampshade you’re using now won’t cover them. However, keep in mind that LED bulbs cannot be completely enclosed in the fixture because the heat will shorten the life of the bulb. If you want to use LED bulbs outdoors, then the bulbs should be weatherproof or able to withstand wet outdoor conditions.
It is important that LED bulbs meet a number of safety standards. If the LED bulb meets the Energy Star standard, it will be a plus. This is because Energy Star certification has high requirements for brightness, color and energy use.
Since LED bulbs are more expensive than traditional bulbs, you should choose a brand that has a manufacturer’s warranty. Such as Impress LED lighting manufacturer’s lights, A good LED bulb should come with at least a three to five year warranty.
Compared to other light sources in many applications, LEDs certainly stand out. In order to keep the system in good condition, the following 5 factors need to be considered.
LED lamps and LED modules are manufactured and driven in a specific current range. LEDs can be supplied with currents ranging from 350mA to 500mA, depending on their characteristics. many systems are driven in the high value region of this current range.
- Acidic Conditions
LEDs are also susceptible to acidic conditions, such as in coastal areas with high salt content, in factories that use chemicals or manufacturing products, or in indoor swimming pools. Although LEDs are also manufactured for these areas, they have to be carefully encapsulated in a fully enclosed housing with a high IP protection rating.
Heat affects the luminous flux and life cycle of LEDs. Heat radiators prevent the system from overheating. A system getting hot means that the allowable ambient temperature of the LED lamp is exceeded. the lifetime of the LED depends on the ambient temperature of the surroundings.
- Mechanical stress
Mechanical stress during the manufacture, stacking or simple manipulation of LEDs can also affect the life of LED lamps and sometimes even destroy them completely. Watch out for electrostatic discharge (ESD), as this can cause brief but high-current pulses that can damage the LED and LED driver.
The performance of LEDs also depends on the humidity of the surrounding environment. Because in a humid environment, electronic devices, metal parts, etc. tend to be damaged quickly and begin to rust, try to keep the LED system free from humidity.
