1.Q: What are the advantages of LED lights?
A: LED (light-emitting diode) lights offer a multitude of advantages over traditional light sources, including lower electricity consumption, much longer lifespan, greater durability, no ultraviolet and infrared radiation, low heat and smaller size.
two.Q: Can I directly replace my existing lamps with LED lamps?
A: The LED lights we offer are direct replacements for incandescent, halogen and CFLs. This means you don’t have to make any changes to your existing system.
3.Q: Why should I choose LED lamps instead of cheaper traditional lamps?
A: Consider not only the initial price of the lamp, but also the actual cost of the light, which includes the cost of energy, replacement and maintenance costs.
– LED lights consume much less energy. When installed in high-hour applications, the saved electricity cost can reduce payback time to less than 2 years.
– LED lights have a much longer life, 30,000 to 50,000 hours. Imagine not having to change your lamps for the next 20 years, especially those that are difficult to access.
For commercial applications, long-lasting LED lights mean lower replacement costs and no more batch lamp replacement. Considering the reduced maintenance costs, the ROI (return on investment) time for LED lamps can be less than 1 year.
LED lamps produce very little heat, which reduces the energy used by your air conditioner.
LED light has no harmful UV (ultraviolet) and IR (infrared) rays.
LED lamps do NOT contain mercury like fluorescent lamps. LED lights are completely safe for nature and can be disposed of as ordinary waste.
Four.Q: Will the low voltage LED fixtures work with my existing transformer?
HAS: Low voltage LED lamps They are compatible with magnetic transformers used with VAC lighting. If you have an electronic transformer, an LED lamp may not work due to its very low power consumption. To function properly, most electronic transformers require a minimum load greater than the 3 watts used by our LED bulbs. By connecting a few LED lamps to a transformer, the load increases to a point where the use of an electronic transformer is acceptable.
5.Q: How does an LED work?
A: The LED (Light Emitting Diode) is an electronic light source that works by the effect of electroluminescence. When a semiconductor diode is turned on, the electrons recombine with the holes and the energy is discharged as light.
6.Q: What is the color of light from an LED?
The color of light from LED lamps is measured by Correlated Color Temperature (CCT) in Kelvins. Contemporary high-power LEDs are coated with phosphor to convert the light from a blue LED into broad-spectrum white light. The most common LED light colors used are:
warm white (soft white) – 2700 – 3300 K – the color of light from a traditional incandescent bulb
Cold white – about 4,000 K – similar to moonlight, xenon lamp light color
daylight white > 5000K: Looks like a flashlight or typical daylight.
7.Q: What is color rendering index?
A: Color Rendering Index (CRI) measures the ability of a light source to accurately simulate the colors of different objects compared to sunlight. Although there are critics of subjective color rendering in practice, CRI is widely used as a measure of light quality. A higher CRI corresponds to better quality light, on a scale of 0 to 100.
8.Q: What is the CRI of the LED light?
A: LED lamps typically score above CRI 80, which is higher than many other light sources. LED lamps with CRI greater than 90 are used for visual inspection tasks.
9.Q: How efficient are LED lamps?
A: The output of light sources is light and heat. The higher the light-to-heat ratio, the more efficient the lamp. Today’s high-efficiency LED lights are around 50% efficient, compared to standard incandescent lamps at 2-3% efficiency and fluorescent lamps at 15-20% efficiency.
LEDs naturally have directional light, this means the light is easier to drive with less loss. That presents an even greater advantage when it comes to the high efficiency of LED lamps over all other existing light sources.
10Q: What is luminous efficacy?
A: Luminous efficacy is the light output per unit of input power. It is measured in lumens per watt (lm/W). Currently, commercially available LEDs have an efficacy of 130 lm/W for cool white light and 107 lm/W for warm white light (CREE XLamp MX-6). This is much higher compared to incandescent bulb which produces 15lm/W and fluorescent lamp with 60-70lm/W.
However, the efficacy of a single LED should not be mixed with the efficacy of the lamp. Many manufacturers and resellers indicate that the light output of the LED lamp is the sum of the output of the individual LEDs. This is not correct because there is always loss of light trapped inside the lamp. The efficacy of an LED light fixture, also called an LED light engine, can be increased through better design and the use of high-quality materials.
elevenQ: Is lumen per watt the only thing I need to consider when choosing an LED light?
A: No, you should also consider the CRI (quality of light) and your individual visual preferences. Some people like warm white (soft) more yellow light that resembles incandescent lamp light. Others prefer cool white/daylight for brighter, truer color rendering.
12Q: What is the lifespan of an LED lamp?
A: When installed correctly and well ventilated, LED lamps rarely burn out. However, the brightness of LED light fades over time, so LED lamp life is measured by 2 characteristics: how much will it fade after 1,000 hours of use, and when will the brightness reach 70% of the normal value? initial.
Quality LED lamps are rated for less than 3% decay in light output for the first 1,000 hours and 30,000 to 50,000 hours for 70% decay, which is the standard for commercial lighting applications.
Once again, compared to traditional light sources, LED lights are superior in lifespan.
13Q: Is the lifespan of an LED light bulb shortened by frequent on/off switches?
A: Unlike fluorescent lamps, the life of LED lamps is NOT affected by frequent changing.
