|C&G LED FAQ|
Q4. Why does LED lighting cost more than traditional lighting?
LEDs can operate as standalone devices, but when grouped or clustered they require additional steps to operate properly. LEDs need proper components such as a circuit board, driving components and some cases and housings to endure the elements. LED circuits can be designed rapidly, but to ensure that they operate correctly and for long periods of time they require testing.
Q5. Are LED lights dimmable?
Dimmable LED bulbs from C&G are dimmable. The dimming IC from NXP which provides even and stable dimming function ranged from 1% to 100% of full luminous flux. Our dimmable LED products are compatible with 99% of dimmers being sold around the world, including LUTRON, OSRAM & TCL.
What this means is that our dimmable LED lighting solutions can be installed in existing homes and businesses out of the box.
Q6. Do LEDs produce heat?
LEDs produce very little amounts of heat. The heat noticed in some instances is due to on board components and other factors of the light circuit. In comparison to incandescent, LEDs produce a fraction of the heat. If LEDs are hot to the touch, they are poorly designed being overpowered due to improper circuitry.
Q7. What does CRI stand for?
The color rendering index (CRI) (sometimes called color rendition index), is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source. It makes red look red, blue look blue, etc.
Q8. How much can I save by using LED lighting solutions?
We provide a free Energy Savings Calculator download which calculates exactly how much you will save over time by switching to LED lighting solutions. With some basic information about cost per kilowatt hour, labor costs, current lighting information and LED info you will know exactly when the ROI and total savings occur.
Q9. How do you make a white LED?
The first method is to combine light from red, green, and blue colored LEDs. If you get the right mix, the effect is white light. This is the same way your television works—a white object on the screen is really depicted using dots of red, green and blue lit up in proportions that form an impression of white. White formed this way can be “tuned” to look warm or cool by adjusting the amounts of colors in the mix.
The second method uses a blue LED with a phosphor coating. The coating emits a yellow light when the blue light from the LED shines on it. The mix of the yellow light with the blue light forms a white light. Inefficiency in the phosphor conversion is one reason that a white LED is less efficient overall than a colored LED. Some of the light energy is lost in the conversion to yellow.
