Queries and Answers About LED Lighting Why LED?

A: LED (Light-Emitting Diode) Lights offer a multitude of benefits over standard light sources including reduced electrical energy usage, much lengthier lifetime, increased durability, no ultraviolet and infrared radiation, reduced warmth and smaller sized dimension.

two.Q: Can I immediately exchange my present lamps with LED lamps?

A: The LED Lights we supply are direct substitute of incandescent, halogen and compact fluorescent lamps. This signifies that you do not have to do any modifications to your existing program.

three.Q: Why should I pick LED lamps above the less expensive classic lamps?

A: Think about not only the first price of the lamp, but the genuine expense of light, which consists of the charge of vitality, alternative and upkeep fees.

- LED lights use significantly less energy. When installed at applications with extended work hrs the saved electrical energy pricecan provide the payback time to less than 2 years.

- LED lights have a lot longer existence, from thirty,000 to fifty,000 hours. Picture that you do not have to modify your lamps for the up coming twenty a long time, especially people challenging to get to light fixtures.

For commercial applications prolonged daily life LED Lights indicate reduced replacement expenses and no much more group relamping. Taken into consideration lowered upkeep fees, the ROI (Return Of Investment) time for LED Lamps can be much less than 1 12 months.

LED lamps produce really small heat hence minimizing the energy employed by your air conditioner.

LED light has no harmful UV (ultraviolet) and IR (infrared) rays.

LED lamps incorporate NO mercury like the fluorescent lamps. LED Lights are totally safe for the Nature and can be disposed as normal waste.

four.Q: Will the Very low Voltage LED lamps perform with my present transformer?

A: Lower Voltage LED lamps are appropriate with magnetic transformers used with VAC lighting. If you have an digital transformer a single LED lamp may not function because of to its quite low power consumption. To work correctly most digital transformers require a minimum load greater than the three-watt employed by our LED Spot Lights. When connecting a handful of LED lamps to a single transformer the load raises to a position in which the use of an electronic transformer is acceptable.

five.Q: How does a LED work?

A: The LED (Light Emitting Diode) is an digital light resource that works by the result of electroluminescence. When a semiconductor diode is turned on electrons recombine with holes and electricity is discharged as light.

6.Q: What is the colour of the light from a LED?

The light color of LED Lamps is measured by Correlated Color Temperature (CCT) in Kelvins. Contemporary Superior Electrical power LEDs are coated with phosphor to convert light from a blue LED to a wide spectrum white light. Most typical LED Light hues employed are:

Warm White (Gentle White) - 2,700 - three,300 K - the color of the light of a standard incandescent light bulb

Cool White - close to four,000 K - equivalent to moonlight, xenon lamp light color

Daylight White > five,000K - looks like flashlight, or standard daylight.

seven.Q: What is Coloration Rendering Index?

A: The Coloration Rendering Index (CRI) is measuring the potential of a light supply to simulate the colors of diverse objects precisely in comparison with the sunlight. Despite the fact that there are critics of the subjective shade rendering in apply, the CRI is broadly utilized as a measurement of the quality of the light. Larger CRI corresponds to etter top quality light, in scale from to a hundred.

8.Q: What is the CRI of LED light?

A: Usually LED lamps score previously mentioned CRI eighty, which is larger thanseveral other light sources. LED Lamps with CRI above ninety are utilized for visual inspection tasks.

nine.Q: How effective LED lamps are?

A: The output of light sources is light and heat. The larger the ratio light to heat, the a lot more effective the lamp. Today's higher successful LED lights have effectiveness of about fifty %, compared to normal incandescent lamp with two-3% and fluorescent lamps with 15-twenty% efficiency.

LEDs normally have directional light, this signifies that the light is easier to control with significantly less losses. That presents an even greater advantage in regards to LED lamps' high effectiveness above all other current light resources.

10.Q: What is luminous efficacy?

A: The luminous efficacy is the light output per unit energy input. It is measured in lumen per watt (lm/W). Currently commercially offered LEDs have efficacy of 130 lm/W for cool white and 107 lm/W for warm white light (CREE XLamp MX-six).This is much increased in comparison to incandescent bulb that produces 15 lm/W and fluorescent lamp with 60-70 lm/W.

Nevertheless, the efficacy of a single LED need to not be mixed with the efficacy of the lamp. Numerous manufacturers and resellers state the LED Lamp Light Output as sum of the output of the individual LEDs. This is not appropriate since there are constantly losses from light trapped inside of the lamp. The efficacy of a LED Light Lamp, also called LED Light Engine, can be elevated by much better design and employing substantial high quality components.

11.Q: Is the lumen per watt the only facet I need to consider when deciding on a LED Light?

A: No, you ought to take into account also the CRI (quality of light) and your person visual preferences. Some folks like the much more yellow Warm (Gentle) White light that resembles the light from the incandescent lamp. Other choose the brighter and much more genuine-color rendering Cool / Daylight white.

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

A: When appropriately installed and nicely ventilated, LED Lamps will very seldom burn up. However, the brightness of the LED light fade over time, so LED Lamp's existence is measured by two attributes - how considerably will it fade after 1,000 hours of exploitation, and when the brightness will get to 70% of the initial worth.

Top quality LED Lamps are rated at much less than 3% light output lessen for the 1st one,000 hrs, and thirty,000 to 50,000 hrs for the 70% decrease, which is the regular for commercial lights applications.

Again, compared to traditional light sources, LED lights are superior relating to lifetime.

13.Q: Does the lifetime of a LED Light Bulb shorten by regular on/off switches?

A: As opposed to the fluorescent lamps, lifespan of LED Lamps is NOT influenced by regular switching.
