Top 25 Knowledge of LED 101 Technology and Fixtures (with Answers)
1. What are LED Lights and do they retailer energy?
All our LED lights and bulbs are energy saving that is designed to substitute incandescent, fluorescent, CFL, steel halide, high strain sodium and halogen lights in your office, facility or business. They will minimize your strength consumption by using at least 40%, and as a lot as 80%, relying on the mild you pick out and the mild we are replacing. With LEDs lasting up to 100,000 hours, we can also minimize your maintenance on your lighting.
2. How do LEDs Work?
LEDs are comprised of 3 main components: the LED’s (the chipset that produces light), the driver (converts AC to DC) and the warmness sink (to hold the entirety cool). LEDs take DC electricity from the driver and create light. The warmness sink captures warmth from the LEDs and the drivers. Although LEDs produce drastically much less heat than the light bulbs we have been used to over the previous century, the warmness they produce needs to be managed. The better this is done, the longer the lifestyles of the product.
LED’s additionally performed the job of converting electricity to mild more efficaciously than different light sources, that is why we can change a 400W metallic halide bulb with a LED 100W retrofit.
3. What are the benefits of replacing your ordinary bulbs with the LED?
There are many benefits. Here is a list of a few:
a. An immediate reduction in your electricity bill.
b. Less heat. LED fixtures are extremely environment-friendly changing electrical energy into light.
c. LED Bulbs last a very long time, typically 50,000 to 100,000 hours.
d. They are genuinely indestructible.
e. They do no longer contain mercury or different hazardous materials
f. Highly recyclable – with no hazardous parts, you can effortlessly reclaim most of the components in an environmentally protected way.
4. How an awful lot money can you shop when converting to LED?
It all depends what you are converting. Incandescent to LED, fluorescent to LED, Metal Halide to LED. Fortunately, we constructed a very easy and information Energy savings calculator. Enter in a few fields or pick one of our present strength financial savings scenario, and let it calculate your electricity savings. We tried to make it easy and handy to use. But it is no longer exclusive to see at least a 70%+ savings on your electricity consumption.
5. Can LED bulbs be used with dimmer controls?
Yes and No.
First, now not all LEDs are dimmable. The driver needs to be designed to permit dimming. Secondly, you must buy the proper type of dimmer. Most retail shops now lift dimmers particularly designed for LED bulbs. Please note, if you buy a non-dimmable LED bulb and attempt to dim it, it will purpose the bulb to fail and additionally void the warranty.
Some of our industrial and business LED fixtures (high bays, floods, place lighting, retrofits) work with a 0-10V dimming system. 0-10V dimming requires one of a kind wiring and a special kind of dimmer.
The two most frequent kinds of dimming are 0-10V low voltage and Triac dimming.
6. Do they incorporate any hazardous or heavy metals like Mercury?
No, LED bulbs do now not contain mercury or any other hazardous metals or chemicals. CFL’s and fluorescent do include a very small quantity of mercury that wishes to be disposed of correctly. So when your LED bulb eventually stops to work, you do not have to worry about pricey or exclusive disposal procedures.
7. What color temperatures on hand with LED bulbs?
Color temperature for light bulbs is measured on the Kelvin scale. LED Bulbs come in a variety of colors, but the most frequent are in a range from 2700K to 7500K. The unfortunate factor is that the solely consistent dimension is the Kelvin scale, Many manufacturers like to use phrases like Day White, Natural White, Warm White and Cool White, but there is now not a trendy that defines a Kelvin temperature to companion with these terms. The widespread rule is WARM (2700K) to COOL(6500K+). The hotter the light, the more yellow tones, the cooler the light, there are greater blue tones.
Here is the normal range of coloration temperatures on MyLEDLightingGuide:
* 2700-3200 – WW – Warm White
* 4000-4500 – NW – Natural White
* 5000-5500 – DW – Day White
* 6500-7500 – CW – Cool White
8. What kind of bases are available?
LED Bulbs are the best retrofit for your existing light fixtures. We have preferred bases, candelabra, standard or Edison (E26), the wealthy person (E39), MR16 and other normal bases that are frequent with incandescent and halogen installations. For fluorescent tubes, we have bi-pin, single pin and HO Ends. Also handy are PL based totally bulbs in G23, GX23, G24 and GX24 bases.
9. What are the sizes of the bulbs? How do they operate in comparison to the original light bulbs?
In most cases, are bulbs are the equal dimension if no longer slightly smaller than the bulbs they replace. That is because LED technological know-how packs a lot of light in a small package.
10. What’s the distinction between LED and CFL?
Both lights are strength efficient mild sources that are a whole lot greater effect than the bulbs they replace. Here is a small list of the differences between CFLs and LEDs:
a. CFLs are the spiral tube like bulbs. They are certainly mini fluorescent bulbs with self-contained ballasts. They incorporate a small quantity of mercury. LED bulbs are the new style looking bulbs with warmth sinks and round mini globes. They do no longer include mercury.
b. You can change a 22W CFL bulb with an 11W LED bulb.
c. LED bulbs are instantaneous on, on the spot off. CFLs take 30 seconds to 1 minute to heat up after they are turned on
d. LED bulbs are now not affected by turning them off and on. CFL bulbs are, as this will limit their life.
11. Can LEDs be used in outdoor lights?
Yes. Some bulbs are designed with waterproof fittings. Others need to be kept in a water-tight fixture. Read all guidelines and manuals before using a LED bulb outdoors.
The specification you need to check for is IP Rating. A bulb or fixture IP65 or larger is regarded as perfect to work in a moist environment.
12. Will the light levels minimize the lifestyles of the bulb?
Yes. They will fade as the bulb receives near the give up of its normal working life. But it is very gradual and barely noticeable. This is known as Lumen Degradation and is denoted on the website as L70. L70 is the amount of time the light takes to get to 70% of the preliminary lumen output.
13. How lengthy do the bulbs last and what sort of warranty is related with your LED bulbs?
Most of our bulbs come with both a 5 or 10 12 months producer warranty. Warranties solely practice for regular use of bulbs and do not encompass misuse or usage for which the bulb was once now not intended to perform. All our warranties are parts-only warranty. We do no longer cowl the price of labor or shipping. All manufacturer installation guidelines ought to be accompanied and the bulbs/fixtures cannot be modified in any fashion.
14. How many lumens do I need to change 400W Metal Halide fixture?
There is a lot that goes into answering this question. DesignLights Consortium has indicated in their specifications that you need at least 10,000 lumens to replace a 400W Metal Halide. Some different factors come into play, like surface reflectivity, obstructions and another source of light, such as natural light sources coming into the building.
MyLEDLightingGuide designs light solutions. We are product agnostic, we will choose the pleasant product that meets your needs. So we have the capability to exchange 400W Metal Halide with 10,000 lumens up to 30,000 lumens. We do discover that you need greater lumens indoors to do a suited alternative than you do outdoors. Lights photometric analysis will determine how tons you want to create the ideal foot candles.
15. How many lumens do I need to replace 400W Metal Halide High Bay?
We discover that the standard variety is as low as 17,000 lumens and as excessive as 23,000 lumens. Photo-metrics performs an essential part in figuring out how a whole lot you need, spacing, and reflectivity of the environment. As we said above, we have determined that you want more lumens indoors than you want outside to substitute 400W Metal Halide.
16. What are the steps required to exchange a fluorescent tube in an existing fixture?
There are countless steps, but genuinely this is no greater difficulty than a bulb and ballast replacement.
1. Remove the fluorescent tubes, and then take away the ballast.
2. Replace the present tombstones (only if necessary). This step may also be required with single-ended powered tubes if you have shunted tombstones.
3. Rewire the fixture to accommodate the LED tubes. Note: there are additionally ballast like-minded tubes that enable you to convert to LED through really removing the historical fluorescent tube and changing it with the LED tube.
Our interior driver LED Tubes to use AC current and then converts the electricity to DC inside the inside LED driver to light the LED. There are some tubes that can be driven from the fluorescent ballast, but we do now not furnish those tubes as we see fluorescent ballasts as an upkeep item. Ballasts devour about 4+ watts per fluorescent tube installed, so leaving the ballast in location reduces the electricity savings as well.
We also can grant externally driven LED tubes. With these tubes, the driver is externally housed outside the tube and is typically hooked up the place the fluorescent ballast was located. External drivers act the equal way as internal drivers; they accept AC power, convert it to DC which is furnished to the LEDs in the tube.
In the case, the place you have a native DC gadget (such as solar systems) you are satisfactory to seem to be for externally pushed LED tubes and forgo the installation of the driver. You will have to make positive the DC electricity that is supplied to the fixture is like-minded with the DC energy requirement of the tubes.
17. What are single ended electricity and double ended energy imply in phrases of fluorescent tubes?
In single-ended powered tubes, you power solely one end. This type of set up is referred to as un-shunted. Since the tube has two pins on that end, you would send a line to one pin and neutral to the other. (think of a line and neutral as the black and white wires of electrical wire)
In double ended powered tubes, you power each ends, one with line source, the other with neutral. This type of set up is referred to as shunted.
In most cases, our tubes our single ended powered tubes. It conforms with the state-of-the-art UL standards for safety. Proper installation of our tubes in present UL fixtures maintains the UL certification of the present fixture.
We can also provide new fluorescent ends (tombstones) so that you can convert over to single-ended powered tubes.
18. What is ballast compatible LED Tubes?
A ballast compatible tube is one the place you can pull out the current tube, depart the ballast installed, and install the LED tube.
19. Do Ballast Compatible Tubes work with all ballasts?
No, however, they work with most digital ballasts.
20. What is L70?
L70 is the amount of time it takes for a light to degrade to 70% of initial lumen output
21. When I buy LED, must I buy primarily based on watts or lumens?
Always purchase based on lumens, watts is a wide variety that is used to determine how a lot of power it takes to produce these lumens. It is essential to pay attention to lumens per watt, or lm/w. The greater the number, the less energy you will want to produce the light. You will be aware that some lights take much less energy to produce the same quantity of light, and this is something you should watch for. Typically, the greater the ratio, the better.
22. What thing of the LED machine is usually the first to fail?
Almost always, it is the driver. That is why it is vital to recognize who makes the driver in the LED fixture or retrofit you purchase. Brand names like Meanwell and Philips are good. A LED product with a 1 or 2-year assurance is an indication of how suitable the driver is in that product. Typically an exact driver final extra than 50,000 hours.
23. What is the most common purpose LEDs fail?
Heat. Heat is the enemy of electronics, the hotter it is, the shorter the light. However, with exact design, you can create a mild or fixture that can stand up to some excessive heat environments. Typically a fixture or bulb with an exterior driver will close longer than an integrated fixture that has the LEDs and driver as one unit.
24. What is CRI?
CRI is the Color Rendering Index. It is a dimension of the first-class of light. Whereas lumens is a measurement of the extent of light, CRI is the dimension of quality. It is a scale between 0 and 100 0 is bad, 100 is great. LED’s usually are in the 70-95 range. The greater the CRI, the greater pricey the LED chip, and therefore the more expensive the product itself.
25. What is the DesignLights Consortium (DLC)?
DLC is DesignLights Consortium, the governing body that certifies the fine and effectivity of LED Lights. It is a fashion similar to Energy Star. Whereas Energy Star is for home proprietor kind products, DLC is for commercial grade LED products. A DLC Qualified product may additionally be eligible for rebates. Your nearby utility designates whether or not you are eligible for rebates or not, and it varies between utility companies. Currently, there are two standards, DLC Standard and DLC Premium. DLC Premium is extra environment-friendly and will keep you more cash in phrases of operating costs.
