1.Q: What are some great benefits of LED Lights?
A: LED (Gentle-Emitting Diode) Lights supply a large number of benefits over conventional gentle sources together with decrease electrical energy consumption, for much longer lifetime, greater sturdiness, no ultraviolet and infrared radiation, low warmth and smaller measurement.
2.Q: Can I immediately exchange my present lamps with LED lamps?
A: The LED Lights we provide are direct substitute of incandescent, halogen and compact fluorescent lamps. Which means you don’t have to do any modifications to your present system.
3.Q: Why ought to I select LED lamps over the cheaper conventional lamps?
A: Contemplate not solely the preliminary worth of the lamp, however the true value of sunshine, which incorporates the price of vitality, substitute and upkeep prices.
– LED lights use a lot much less vitality. When put in at functions with lengthy work hours the saved electrical energy value can deliver the payback time to lower than 2 years.
– LED lights have for much longer life, from 30,000 to 50,000 hours. Think about that you simply don’t have to alter your lamps for the following 20 years, particularly these laborious to achieve lighting fixtures.
For business functions lengthy life LED Lights imply decrease substitute prices and no extra group relamping. Considered decreased upkeep prices, the ROI (Return Of Funding) time for LED Lamps might be lower than 1 12 months.
LED lamps produce little or no warmth thus decreasing the ability utilized by your air conditioner.
LED gentle has no dangerous UV (ultraviolet) and IR (infrared) rays.
LED lamps include NO mercury just like the fluorescent lamps. LED Lights are fully protected for the Nature and might be disposed as unusual waste.
4.Q: Will the Low Voltage LED lamps work with my present transformer?
A: Low Voltage LED lamps are appropriate with magnetic transformers used with VAC lighting. In case you have an digital transformer one LED lamp could not work because of its very low energy consumption. To work correctly most digital transformers require a minimal load better than the 3-watt utilized by our LED Spot Lights. When connecting just a few LED lamps to 1 transformer the load will increase to some extent the place the usage of an digital transformer is appropriate.
5.Q: How does a LED work?
A: The LED (Gentle Emitting Diode) is an digital gentle supply that works by the impact of electroluminescence. When a semiconductor diode is turned on electrons recombine with holes and vitality is discharged as gentle.
6.Q: What’s the coloration of the sunshine from a LED?
The sunshine coloration of LED Lamps is measured by Correlated Shade Temperature (CCT) in Kelvins. Up to date Excessive Energy LEDs are lined with phosphor to transform gentle from a blue LED to a large spectrum white gentle. Commonest LED Gentle colours used are:
Heat White (Gentle White) – 2,700 – 3,300 Ok – the colour of the sunshine of a standard incandescent gentle bulb
Cool White – round 4,000 Ok – much like moonlight, xenon lamp gentle coloration
Daylight White > 5,000K – seems to be like flashlight, or typical daylight.
7.Q: What’s Shade Rendering Index?
A: The Shade Rendering Index (CRI) is measuring the power of a lightweight supply to simulate the colours of various objects precisely compared with the daylight. Though there are critics of the subjective coloration rendering in follow, the CRI is broadly used as a measurement of the standard of the sunshine. Larger CRI corresponds to etter high quality gentle, in scale from 0 to 100.
8.Q: What’s the CRI of LED gentle?
A: Typically LED lamps rating above CRI 80, which is greater than many different gentle sources. LED Lamps with CRI above 90 are used for visible inspection duties.
9.Q: How environment friendly LED lamps are?
A: The output of sunshine sources is gentle and warmth. The upper the ratio gentle to warmth, the extra environment friendly the lamp. At the moment’s excessive environment friendly LED lights have effectivity of about 50 %, in comparison with customary incandescent lamp with 2-3% and fluorescent lamps with 15-20% effectivity.
LEDs naturally have directional gentle, which means that the sunshine is less complicated to handle with much less losses. That presents a fair better benefit with regard to LED lamps’ excessive effectivity over all different present gentle sources.
10.Q: What’s luminous efficacy?
A: The luminous efficacy is the sunshine output per unit energy enter. It’s measured in lumen per watt (lm/W). These days commercially out there LEDs have efficacy of 130 lm/W for cool white and 107 lm/W for heat white gentle (CREE XLamp MX-6). That is a lot greater in comparison with incandescent bulb that produces 15 lm/W and fluorescent lamp with 60-70 lm/W.
Nonetheless, the efficacy of a single LED shouldn’t be combined with the efficacy of the lamp. Many producers and resellers state the LED Lamp Gentle Output as sum of the output of the person LEDs. This isn’t right as a result of there are at all times losses from gentle trapped contained in the lamp. The efficacy of a LED Gentle Lamp, additionally known as LED Gentle Engine, might be elevated by higher design and utilizing top quality supplies.
11.Q: Is the lumen per watt the one facet I ought to take into account when selecting a LED Gentle?
A: No, it’s best to take into account additionally the CRI (high quality of sunshine) and your particular person visible preferences. Some folks just like the extra yellow Heat (Gentle) White gentle that resembles the sunshine from the incandescent lamp. Different desire the brighter and extra true-color rendering Cool / Daylight white.
12.Q: What’s the lifetime of a LED Lamp?
A: When correctly put in and properly ventilated, LED Lamps will very not often burn. Nonetheless, the brightness of the LED gentle fade over time, so LED Lamp’s life is measured by 2 traits – how a lot will it fade after 1,000 hours of exploitation, and when the brightness will attain 70% of the preliminary worth.
High quality LED Lamps are rated at lower than 3% gentle output lower for the primary 1,000 hours, and 30,000 to 50,000 hours for the 70% lower, which is the usual for business lighting functions.
Once more, in comparison with conventional gentle sources, LED lights are superior relating to lifetime.
13.Q: Does the lifetime of a LED Gentle Bulb shorten by frequent on/off switches?
A: In contrast to the fluorescent lamps, lifespan of LED Lamps is NOT influenced by frequent switching.
