Questions and Answers About LED Lighting – Why LED?

1.Q: What are the advantages of LED Lights?

A: LED (Light-Emitting Diode) Lights offer a multitude of benefits over traditional mild resources which include decrease electricity consumption, a great deal longer lifetime, better sturdiness, no ultraviolet and infrared radiation, low heat and smaller size.

2.Q: Can I immediately update my present lamps with LED lamps?

A: The LED Lights we provide are direct substitute of incandescent, halogen and compact fluorescent lamps. This means that you do not need to do any changes to your current device.

Three.Q: Why have to I select LED  IK rating lamps over the less expensive conventional lamps?

A: Consider not only the preliminary fee of the lamp, however the proper cost of light, which incorporates the fee of energy, substitute and preservation prices.

– LED lighting use tons much less strength. When set up at packages with lengthy paintings hours the saved power fee can deliver the payback time to less than 2 years.

– LED lighting fixtures have a good deal longer existence, from 30,000 to 50,000 hours. Imagine that you do now not need to trade your lamps for the following two decades, specially the ones difficult to reach mild furnishings.

For industrial programs lengthy life LED Lights mean lower substitute expenses and no greater organization relamping. Taken into consideration reduced maintenance charges, the ROI (Return Of Investment) time for LED Lamps may be much less than 1 year.

LED lamps produce little or no warmness for this reason decreasing the electricity utilized by your air conditioner.

LED mild has no dangerous UV (ultraviolet) and IR (infrared) rays.

LED lamps contain NO mercury like the fluorescent lamps. LED Lights are completely safe for the Nature and can be disposed as regular waste.

4.Q: Will the Low Voltage LED lamps paintings with my present transformer?

A: Low Voltage LED lamps are compatible with magnetic transformers used with VAC lighting fixtures. If you’ve got an digital transformer one LED lamp might not work due to its very low power consumption. To work properly most digital transformers require a minimal load greater than the three-watt utilized by our LED Spot Lights. When connecting a few LED lamps to at least one transformer the load increases to a point where the use of an electronic transformer is suitable.

5.Q: How does a LED paintings?

A: The LED (Light Emitting Diode) is an electronic mild supply that works by the effect of electroluminescence. When a semiconductor diode is became on electrons recombine with holes and power is discharged as mild.

6.Q: What is the color of the mild from a LED?

The mild shade of LED Lamps is measured via Correlated Color Temperature (CCT) in Kelvins. Contemporary High Power LEDs are blanketed with phosphor to transform light from a blue LED to a huge spectrum white light. Most commonplace LED Light colours used are:

Warm White (Soft White) – 2,seven hundred – three,three hundred K – the coloration of the light of a conventional incandescent light bulb

Cool White – around 4,000 K – similar to moonlight, xenon lamp light shade

Daylight White > 5,000K – seems like flashlight, or normal sunlight hours.

7.Q: What is Color Rendering Index?

A: The Color Rendering Index (CRI) is measuring the capacity of a light source to simulate the colors of various items as it should be in evaluation with the sunlight. Although there are critics of the subjective color rendering in exercise, the CRI is widely used as a measurement of the excellent of the light. Higher CRI corresponds to etter first-rate light, in scale from 0 to a hundred.

Eight.Q: What is the CRI of LED mild?

A: Generally LED lamps rating above CRI eighty, that is better than many other mild sources. LED Lamps with CRI above 90 are used for visible inspection obligations.

9.Q: How green LED lamps are?

A: The output of light assets is mild and heat. The better the ratio light to warmth, the greater green the lamp. Today’s high green LED lighting have performance of approximately 50 %, compared to conventional incandescent lamp with 2-3% and fluorescent lamps with 15-20% efficiency.

LEDs evidently have directional light, because of this the mild is less difficult to manipulate with much less losses. That affords a fair more advantage in regards to LED lamps’ excessive performance over all other current light resources.

10.Q: What is luminous efficacy?

A: The luminous efficacy is the mild output in line with unit electricity enter. It is measured in lumen in keeping with watt (lm/W). Nowadays commercially available LEDs have efficacy of a hundred thirty lm/W for cool white and 107 lm/W for warm white mild (CREE XLamp MX-6). This is a good deal higher in comparison to incandescent bulb that produces 15 lm/W and fluorescent lamp with 60-70 lm/W.

However, the efficacy of a unmarried LED ought to now not be mixed with the efficacy of the lamp. Many manufacturers and resellers kingdom the LED Lamp Light Output as sum of the output of the person LEDs. This isn’t always accurate due to the fact there are continually losses from light trapped inside the lamp. The efficacy of a LED Light Lamp, additionally called LED Light Engine, can be elevated by higher design and the usage of excessive best substances.

Eleven.Q: Is the lumen consistent with watt the handiest element I should do not forget while deciding on a LED Light?

A: No, you have to do not forget additionally the CRI (excellent of light) and your person visible choices. Some human beings like the greater yellow Warm (Soft) White mild that resembles the light from the incandescent lamp. Other select the brighter and more true-colour rendering Cool / Daylight white.

12.Q: What is the lifetime of a LED Lamp?

A: When well set up and well ventilated, LED Lamps will very rarely burn. However, the brightness of the LED mild fade over time, so LED Lamp’s life is measured by using 2 traits – how plenty will it fade after 1,000 hours of exploitation, and when the brightness will reach 70% of the initial price.

Quality LED Lamps are rated at less than 3% mild output lower for the first 1,000 hours, and 30,000 to 50,000 hours for the 70% decrease, which is the usual for business lighting fixtures packages.
