FAQ

According to Energy Star in U.S., LED light source use 75-80 percent less electricity than incandescent bulbs and fluorescent bulbs, to produce the same lumen output of light; and can have a lifespan up to 10 times longer than traditional light sources.

Average LED lightings in the current market produce in the range of 90~150 lumens per watt, depending on the type of LED.

LED lighting normally doesn’t burn out like other traditional light sources. They get increasingly dimmer over time. This process is usually called lumen depreciation. The lifecycle of LED is basically based on the operating hours until it emits 70% of its initial light output.

A normal incandescent lamp can last about 600-800 hours, while a CFL may last for about 6,000-10,000 hours. The best quality fluorescent lamps can last for 30,000 hours.

Top-quality LED lighting with good designed fixtures usually has an efficient life of 50,000-60,000 hours. Some highly emerged designs may also exceed 100,000 hours.

LED strip lights and other decorative LED options are available in most colors: red, orange, yellow, green, blue, violet, pink, and purple are the options. Most regular LED lightings are classified as several different types of white with Color Temperature, which is measured in degrees of Kelvin (K).

At INLEDS Lighting, the main color temperatures are “Warm White” (2700K-3000K), “Cool White”/ ”Natural White” (4000K-4500K), and “Day Light”/ ”Pure White” (6000K-6500K).

Phosphor layers are chemical coatings on LED chips that gives its colors. Color changes are very often caused by degradation of the phosphor layers. It is important to buy LED lights mounted with quality LED chips.

Other causes of color change would most likely be the diffuser which is usually made of plastics that have changed color due to degradation or aging and/or exposed to heat for over a long period of time.

At INLEDS Lighting we supply products mounted with high quality LED chips, some of them are: Lumileds 3030 & 5050, Cree, Epistar, Philips etc.

LEDs do give off some heat, but much less than energy-saving sticks, twisters and traditional light bulbs. Just as importantly, when used in your light fittings at home, LEDs don’t emit infrared (IR), only visible light. You can’t see IR so it doesn’t add to the brightness of the light; it just makes bulbs hotter and wastes energy. Another plus point is that LEDs don’t emit ultraviolet (UV) light either.

LEDs have a characteristic of current-voltage; the current is dependent exponentially on the voltage. This means that a small change in voltage can cause a large change in current. LED can be damaged or destroyed if the applied voltage exceeds the forward voltage drop by a small amount as the current rating may be exceed by a large amount. Constant-current LED drivers keep the current below the LED’s maximum current rating. Some LED fixtures like GU10 spotlight includes a current-limiting resistor.

At INLEDS Lighting we use quality power supplies from established brands that are certified with international standard, such as MEAN WELL, Moso, Eaglerise, Inventronics etc.

Most failures are caused by low quality power supply units that could not control the voltage and current well (see the question above), the power supply burned itself out (poor components), and/or used the wrong voltage and/or current power supply. A typical good LED power supply (driver) should withstand 2-3 years of continuous usage. Just like any traditional light source like incandescent bulbs and fluorescent tubes, it is wiser to leave the lights on for a longer period of time than turning it-on-and off multiple times. The cost of saving that little electricity will not cover the cost of your light breaking down.

Although the initial cost of a LED bulb is higher than that of a traditional light bulb, in the long term you save money. The initial investment is more than paid back over the life of the bulb because the running costs are lower due to lower energy consumption and they won’t need replacing for a very long time, typically around 15 years. And don’t forget that the prices for LED lighting now are already lower than a few years ago, and are getting closer to the prices of traditional bulbs, the added value will increase.

Our LED lights have a lifespan of at least 20,000 hours, they also consume up to 80% less energy than traditional lamps, so you’ll soon enjoy savings in your energy bill. At INLEDS Lighting we are focused on products that are more effective than many ‘similar’ LED lamps with the same wattage and color temperature, so you get brighter illumination for the same energy consumption.

LED Lights do not accumulate harmful chemicals in the environment. The compact fluorescent lights which have 4 to 5 milligrams of mercury present in each of them, LEDs do not contain mercury, lead or other toxic materials which can be hazardous for environment or public health, and are completely recyclable just like most other electronic devices.

Greenhouse gas emissions associated with the LED lights are relatively far less than the conventional incandescent or Compact fluorescent lights. According to carful calculations, one LED bulbs, providing the same luminosity as one incandescent bulb emits 80% less greenhouse gases. The same calculation for CFLs suggest a reduction of 50% GHGs by switching to LED lights.
