How to choose the ideal LED light bulb.


When you are looking for the ideal LED light bulb for your home or office, you must first clarify what your requirements are, and then choose the light and colour you need. Or you might just want to find an alternative to a regular 60-watt incandescent bulb. So, what do you need to consider when choosing an LED bulb? How to choose the right LED bulb? Low wattage, high lumen 


The first thing you should consider is how to save power and reduce electricity bills. 


If the lumen of the lamp is high, then the light is brighter. Compared with incandescent bulbs, LED bulbs can provide many lumens in just a few watts. So, you need to find a low-wattage, high-lumen bulb, because it saves electricity. On average, a 12-watt LED bulb can provide the same amount of light as a 60-watt incandescent bulb. This means you can save a lot of electricity, which saves electricity bills. 


Second Life, you should consider the life of the LED bulb. 


If used three hours a day throughout the year, most LED bulbs can provide 25,000 to 50,000 hours of light. 


Colour and colour rendering index The third thing you should consider is the colour 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 colour temperature, the lower the Kelvin, the more yellow the white light appears. If the colour temperature is higher, it becomes bluish. If you want warm colours, you need to find about 2700K LEDs. At 3000K, the light is more like a halogen lamp. For cool white light, look for 3500K to 4100K bulbs. 5000K to 6500K bulbs mimic natural or daylight. Another aspect of colour is the colour rendering index (CRI), which reflects the accuracy of the colour under light. The higher the colour rendering index, the more objects the LED bulb illuminates. The propagation of light LED bulbs emits light in a specific direction. 


It is important to find out the angle at which the LED light bulb is spreading. 


The propagation of light is called the beam angle. The beam angles of LED bulbs on the market are 15, 30, 45, 60, and 100, while 120 and 180 are rarely. The beam angle is less than 30, can be used as a spotlight, its brightness or lumens per watt is the highest. Most of them have a wattage of less than 5 and are particularly suitable for shops and places where particular 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 the room, usually with a power rating of more than 5W. Multiple such downlights can be used to illuminate the room. If the ceiling is high (more than 3 meters), a beam angle of 30-45 degrees is sufficient. If the ceiling is below 3 meters, a beam angle of 60-100 degrees is best. The beam angle can be increased by placing the reflector and diffuser, but the problem is that if the beam angle increases, the lumen (or brightness) will decrease. 


Points to note when using LED lights.


The right luminaire LED light is a bit heavier than a traditional light bulb, so you should check if your existing luminaire can support the weight of the LED light bulb. And because these bulbs are longer, you may not be able to cover them with the lampshade you are using. However, keep in mind that LED bulbs cannot be completely enclosed in the luminaire, as heat will shorten the life of the bulb. If you want to use LED bulbs outdoors, they must be weatherproof or able to withstand wet outdoor conditions.


Safety standards and warranty hours for LED bulbs.


It is important that product certification LED bulbs meet certain safety standards. If the LED bulb meets the ENERGY STAR standard, it will add a lot of points. Because Energy Star certification places high demands on brightness, color, and energy use. Warranty Period Since LED bulbs are more expensive than traditional bulbs, you should choose a brand with a manufacturer warranty. A good LED bulb should have a warranty of at least three to five years. 


The unique advantages of LED lights.


4 unique advantages of LED for landscape lighting Brighter and better light The main functions of landscape lighting are security and decoration. LEDs are considered the brightest form of light, can achieve 170-180 lumens per watt, and provide reliable light. In addition to this feature, LEDs are unlikely to explode or burn out at the light source under conditions of overheating or short circuit. Environmentally friendly LEDs do not emit any infrared or ultraviolet radiation and are completely free of mercury. Also, these lamps are ROHS compliant, which means that LEDs do not contain any hazardous substances such as cadmium, mercury, etc. In contrast, metal halide lamps contain high levels of cadmium and emit ultraviolet light while fluorescent lamps contain mercury. Because landscape lights are installed near water bodies or trees close to nature, LEDs are preferred. Low maintenance costs The presence of light sources in backyard lights is important because the location of the backyard lights is usually in fragile areas. For example, underwater lights in swimming pools are difficult to replace, because the swimming pool should be emptied if the lights are changed. Another example is floodlights. If something goes wrong, a crane is needed to recover. In most cases, the cost of replacing the light is much higher than the cost of the light. The function voltage of low-voltage operation LED is lower than 4V DC. To run it at 220V, we usually use a switching power supply to reduce the voltage to convert AC to DC. If it is any lamp that is in direct contact with water, it is recommended to operate at a lower voltage to avoid disaster when the current flows. When it comes to traditional light sources, we need to use a specific inverter circuit to increase the voltage and convert it to alternating current. This reduces the safety and life of the luminaire, while increasing the cost of the luminaire. Also LED is a safer option, operates at low voltage and is very safe during operation.
