What is high efficiency LED lighting?
Reduces energy costs — uses up to 90% less energy than incandescent lighting, saving on operating expenses. Reduces maintenance costs — lasts 35 to 50 times longer than incandescent lighting and about 2 to 5 times longer than fluorescent lighting.
Determine the needed lumens
A lumen is a unit measurement of light. To determine the needed lumens, you will need to multiply your room's square footage by your room's foot-candle requirement. For example, a 100-square-foot living room, which needs 10-20 foot candles, will need 1,000-2,000 lumens.
While energy conversion efficiency of incandescent lamps is between 10 and 20 percent, highly efficient LEDs currently achieve values between 40 and 50 percent. Nevertheless, this means that 50 to 60 percent of the power is lost as heat.
Top Performance LEDs: These LEDs have the highest luminous efficacy, around 220 lm/w. Examples include the Nichia 757G LEDs. High Performance LEDs: These LEDs offer good performance with a luminous efficacy of 150-200 lm/w. Many reputable manufacturers produce LEDs in this category.
Solid State Light Emitting Diodes (LEDs)
ENERGY STAR certified LED products use at least 75% less energy and last up to 25 times longer than traditional incandescent lighting. By 2027, widespread use of LEDs could save about 348 terawatt hours of electricity.
Tube LED Lights
These LEDs offer a functional choice for lighting professional workspaces, kitchens, and office buildings. Tube LED lights also last significantly longer than fluorescent bulbs.
Ultra Long LED Strip Lights: 4 rolls of 25FT LED lights, ultra 100ft length are long enough to decorate your entire room.
50-foot LED lights, in particular, are just the right length to stretch across a whole room and add in a bright pop of color. The adhesive backing makes installation quick and easy, and each light strip requires only a power outlet to illuminate as well.
Which type of light is brightest? When compared to other types of lighting product, LED lights are the most energy efficient and offer a brighter light for the same wattage. Good quality LED fixtures now output around 170 lumens per watt; a fluorescent puts out around 110.
The energy efficiency of LED products is typically characterized using efficacy, which in basic terms is the ratio of power input to light output—or more technically, emitted flux (lumens) divided by power draw (watts).
What percentage are LED lights more efficient?
LED light bulbs use up to 85% less electricity than traditional light bulbs and 95% of that energy is converted to light with only 5% wasted as heat.
Lighting efficiency
This is the ratio between the total luminous flux emitted by a device and the total amount of input power (electrical, etc.) it consumes.
Forget watts…
Lumens equal brightness; watts measure energy used. LEDs use much fewer watts than incandescents with the same brightness. As a rule, you'll replace a standard 75W bulb with an energy-saving bulb of about 1100 lumens. On the low end, replace a 40W bulb with an LED bulb of about 450 lumens.
| Lumens | Incandescent bulb | LED bulb |
|---|---|---|
| 75-110 | 9 watts | 1 watt |
| 730-800 | 60 watts | 7-9 watts |
| 1380-1600 | 100 watts | 12-14 watts |
| 2000-2500 | 150 watts | 28-23 watts |
The average LED Light Bulb uses 10 watts. Your devices wattage may be different depending on the brand, size, or other factors. You can generally find the wattage of your LED Light Bulb in the user manual or on the device itself.
LED tube lighting is the better choice because it lasts about 40,000 hours longer in testing, is more energy efficient, will save you more money, and will leave less impact on the environment.

|---|---|
| Living rooms general | 50-150 |
| Casual reading | 150 |
| Study | 150-750 |
| Bedroom general | 50-150 |
On average, a 16-foot LED strip light uses around 36 watts of electricity per hour. If you use a 16-foot LED strip for 6 hours a day, you will use 216 watts of electricity per day, or 0.216 kWh. Over a year, this would add up to 78.84 kWh.

Warm white or soft white lights in the 2700K-3000K range can help you relax and get a good night's sleep, while cool white lights in the 5000K-6500K range can boost your productivity and focus.
How do I choose the brightest LED light?
Simply take your current incandescent watts and select the corresponding LED bulb equivalent on the lumens brightness scale. Pay close attention to lumens, since this number indicates the brightness, or light output, of the bulb.
Keep your fixtures between 1.5 and 3 feet away from the wall. Space fixtures equidistant from each other.
As a general guide, lower kelvin bulbs give you warm white colour, while medium K bulbs deliver neutral whites, and higher K bulbs are close to daylight quality. For example, to replace a 60-watt filament bulb, you could select an LED with a lumen rating of 800, kelvin of 3000 and 8-12 watts.
To determine the needed lumens, you will need to multiply your room square footage by your room foot-candle requirement. For example, a 100 square foot living room, which needs 10-20 foot-candles, will need 1,000-2,000 lumens. A 100 square foot dining room, which needs 30-40 foot-candles, will need 3,000-4,000 lumens.
Easy Installation---15FT TV led lights 65-75 inch is long enough to light up every side of your TV.
A pixel pitch of 1 (mm) millimeters to 3 (mm) millimeters or lower are recommended for close viewing LED display. And for LED displays used for outdoor events, 3 mm to 6mm or higher are commonly preferred pixel pitches.
12V LED light strips can be up to 5m in length, may can be cut to the required length. 24V LED light strips can be up to 10m long, again many can be cut to length. 240V LED light strips are a relatively new technology but can be up to 100m long.
The 100 LED has 100 lights whereas the 200 led has 200 lights. Was this helpful? Thank you for your feedback!
In any room, they can add brightness, color and energy. Whether you're looking to add some flair with color or simply trying to brighten up a room, LED lights are one of the best lighting options on the market today.
If they have the same lumen count, they will be equally bright. However, you may perceive the daylight bulb as brighter of the two because it lies in the cooler temperature range of blue. Colour temperatures are measured in Kelvin on a scale of 1,000 – 10,000.
What are disadvantages of LED?
- LED does not release white Light emitted directly. The colors are red, blue, and green. ...
- The Light produced by the LED is directional, i.e., they are emitted in one direction. ...
- LEDs do not possess filament that could be damaged, but LED has a problem with lumen depreciation.
Efficacy is getting things done. It is the ability to produce a desired amount of the desired effect, or success in achieving a given goal. Efficiency is doing things in the most economical way. It is the ratio of the output to the inputs of any system (good input to output ratio).
LEDs use much less energy to provide the same amount of light as other forms of lighting. One of the main reasons LEDs are so efficient is that most of their energy is used to solely create light, rather than creating light and heat, as less efficient forms of lighting do.
LED lighting means sustainable lighting in so many ways. First, LED lights save up to 90% energy compared to a traditional bulb with the same light output.
That's because LEDs are designed to be as efficient as possible without compromising the quality of the light -- and some LEDs are better at the job than others. For example, an LED bulb with comparable brightness to a 60-watt incandescent will typically only draw 8 to 12 watts.
Switch to LEDs
LEDs are better value and can be used in the majority of existing fittings. LEDs use about 75% less energy than halogen light bulbs and last 5 to 10 times longer, greatly reducing replacement costs and the number of light bulbs ending up in landfill.
“Efficiency” is the percentage of light emitted from a light fixture and light source when energized. “Efficacy” is the amount of useable light from a source per unit of electrical measure, or Lumens/Watt.
The most common choice among them are 65-watt replacement bulbs that typically put out about 650 lumens of light each. That's a good, average number, and fine for average-height ceilings with at least a few bulbs shining overhead.
For example, if you wanted to replace a 60-watt incandescent bulb, what wattage LED bulb would be roughly equivalent? Using the 7:1 ratio, simply divide 60 watts by 7 to get roughly 9 watts.
For home theater projectors where ambient light is kept to a minimum, you'll need a minimum of 1500 lumens. For classrooms, conference rooms or rooms with windows, a projector with a minimum of 2500 lumens is best. For large auditoriums or lecture halls, you'll need more lumens.
Does more watts mean brighter light?
A standard 40W bulb is equal to 400+ lumens, which represents the brightness of a bulb. Typically, the higher the wattage, the higher the lumens, and the greater output of light.
But there's no problem using a 100-watt equivalent LED bulb, which is only about 17 watts and therefore well under the safety limit of a 60-watt maximum fixture.
Using a light bulb with too high of wattage can lead to overheating of the light bulb. This heat can melt the light socket as well as the insulation of the wires. Once that happens, you put yourself at risk of arc faults, and this is something that could even lead to property fires.
For most applications,LED bulbs with lumen ratings of between 800 and 1,100 lumens are fine. A 60 watt incandescent bulb gives off 800 lumens, while a 75 watt incandescent gives off 1,100 lumens.
Watts to Lumens – Energy Output to Brightness Produced
40-watt bulb produces 450 lumens of light. 60-watt bulb produces 800 lumens of light (most widely used in households) 75-watt bulb produces 1,100 lumens of light. 100-watt bulb produces 1,600 lumens of light.
A 1000 lumen flashlight is quite bright and, depending on the lens or reflector design, powerful enough to reach a distance of 200 meters or more. This type of flashlight allows you to see objects from a far distance.
LEDs with power between 0.05 W and 0.10 W are in the Low-Power class. LEDs with a power range of 0.25 W to 0.50 W are known as Mid-Power, those with a power range of 1 W to 3 W are known as High-Power LEDs. Low-Power LEDs have low brightness, so they are often used as indicator lights.
Be cautious of LEDs that haven't earned ENERGY STAR certification. Low quality non-certified bulbs may be cheaper at the register, but you may find that they flicker, shift in color, look dim, have uneven light the longer you use them, and shorter life spans.
It is an industry standard that cool white LEDs are brighter than warm white.
Supplying Power
Adjusting the voltage lower or higher will change the brightness, but only because it also changes the current- higher voltage means the current will increase in an LED.
How many watts is good for LED?
Watt is a measure of power, it depends on how much power you want your light bulbs to use. Most LED light bulbs are between 5 and 8 watts, so a good range for home use would be between 40 and 80 watts.
The short answer is yes. As with many products, you get what you pay for when it comes to LED lighting. The difference in quality can be quite noticeable. An initial investment for high quality LED lights can actually cost less in the long run when you factor in maintenance, light quality and energy savings.
Testing LED lights is simple with a digital multimeter, which will give you a clear reading of how strong each light is. The brightness of the LED while you test it will also indicate its quality.
Over-heating can be a result of a number of design and assembly issues but is still the cause of the majority of LED lamp failures – both in the fitting themselves and also the drivers.
Some people who have used LED bulbs have noticed that they are usually whiter and brighter than regular incandescent light bulbs. As such, some people feel that these LED bulbs make their home feel like a hospital operating room or a chemical laboratory. People are accustomed to warmer light.
