It is a common misconception that wattage is the measurement that defines the brightness output of a bulb. Unfortunately it has become the determining factor by which a bulb is chosen and purchased by the consumer. Wattage is actually the amount of energy consumed by a bulb to produce light. To determine the actual amount of light a bulb produces, one must check the lumen (lm) value output. The higher the lumen value, the brighter the light produced by the bulb. So when you are searching for the right replacement bulb, look for a lumen value similar to that of the bulb you are replacing. The lumen value is specified on the label cover along with other details of the bulb.
Yes, LED dimmable lighting is now available. Not all LEDs are dimmable so to avoid disappointment, please ensure that the product packaging clearly states that it is in fact dimmable prior to purchasing. With dimmable LED technology you will be able to control your lighting and enjoy savings over and above the benefits that come with non-dimmable LED bulbs.
The dimmable LEDs are controlled with a dimmer switch and assists in creating a variety of lighting effects.
Whether brighter for reading or softer for that romantic dinner, LED dimmable lights will achieve the results you need.
The most common standard LED bulbs available in the market will vary in brightness from 50 lm-1200 lm. The brightest LED bulbs used in standard fixtures would be flood lights and spotlights. Common rule of thumb is that different wattages achieve different levels of radiance. Therefore it is best to first calculate the size of the area to be illuminated before selecting the right bulb and wattage for your needs.
Whether you are looking for spotlighting (directional lighting) or a more dispersed type of lighting, LED is available in options that will meet your needs. Always remember that similar to traditional lighting, different fixtures may require different types of LED bulbs to achieve maximum output.
Using the right replacement bulb the light output from a traditional 120 watt incandescent bulb can be achieved from a 25 watt LED bulb. Even though LEDs are compact, they are comparable in efficiency and effectiveness. Even if you replaced a conventional bulb with multiple LEDs for the same light output, the savings are there.
LED light bulbs are tremendously more efficient than traditional incandescent bulbs. Almost five times more to be exact. An LED light bulb using 1/5th of the wattage of a conventional bulb will produce the similar amount of light output. LED bulbs are able to produce focused or directional lighting. Therefore depending on the application, an LED may be as much as 10 times more effective than incandescent bulbs.
There are two more big advantages LED lights have over incandescent. The first is the fact that LED lights have a tremendous life span. Depending on the bulb and application, the life span could easily reach as long as 10 to 15 years! The second is that unlike incandescent or CFL, LED lights do not heat up. Hot lights have been responsible for many fires and the burns over the years. LED lighting is a far safer solution for everyone.
The savings by switching to LED lighting can be found in several areas. When LED lighting was first introduced into the marketplace, the biggest deterrent was the initial cost. However, LED technology has advanced at a tremendous rate and with it the price has dropped significantly. Costs still remain higher than a traditional bulb but the returns easily justify the cost. The equivalent replacement for an average 100 watt incandescent bulb is a single 14 Watt LED. This represents a 86% drop in electricity required to provide the same lighting. The lifespan of an LED light is by far greater than that of a traditional bulb. In some cases more than 25 times! An LED bulb may last as long as five to seven years which equates to almost eliminating the purchase of a replacement bulb off your "to do" list. How many times will you have to replace an incandescent over the same time period? Finally the safety factor. LED bulbs do not heat up. Traditional bulbs generate a tremendous amount of heat. Heat that have over time caused many burns and too many fires.
The light output from a bulb is dependent upon LEDs embedded inside it. But the size and number of LEDs is not the deciding factor behind the illumination intensity of a bulb. The accurate way to find the brightness of a bulb can be measured in lumens or lux. Lumens measure the total amount of light output from a bulb. Lux is a measurement that determines the extent of brightness that is falling on a surface at a specific distance.
The lumens value of a bulb is specified on the label which represents the standard metric to determine the brightness output of a bulb. You can also find lux value of a bulb’s output with the many calculation tools available online.
LED light bulbs are the brightest in the category compared to any bulb manufactured in the market. For the amount of wattage that an LED consumes, you can enjoy savings of almost 80% to 90% electricity compared to that of incandescent bulb. A 14 Watt LED bulb can replace a 100 watt incandescent bulb. To achievie equivalent lighting output in any scenario, simply look for lumens produced by the LED bulb outlined on the package.
LED bulbs are available to fit in almost any fixture, are the perfect retrofit alternative and are perfectly suited to enhance the decor in any environment.
Colour correlated temperature (CCT) is the measure of colour appearance that an LED bulb emits. CCT values indicate ‘warmth’ or ‘coolness’ of the light emitted from the source. The colour (CCT)of LED bulbs ranges from warm yellow (2700K) to cool blue white (7000K). Neutral white comes in the a color range of 4500K while cool white fluorescent comes in the range of 6000K or more.
By comparison, a typical incandescent bulb comes with a CCT of 2800K. A typical halogen is a bit higher, around 3500K. However, light is perceived differently depending upon the surroundings and conditions.
Background light has a huge effect on the appearance of colours perceived by the human eye. Light will appear different in a dark room compared to that of the same room exposed to sunlight. Even though colour consistency standards are being followed at the manufacturing stage, these differences are a result of variations in the surroundings.
Light has a psychological effect on moods and small variations in light colour have an influence on the disposition of a person. It is important to choose the right bulb with the right colour to create the ambiance you desire.
An LED spotlight produces a narrow beam of light, typically less than a 45 degree wide angle. Most of the illumination from a spotlight is concentrated onto a small area producing a bright spot. LED floodlights however emit a wide beam of light, up to 120 degrees, producing light that is spread out over a larger area but with less brightness than the spotlight.
Because the light is more concentrated, a spotlight will appear brighter than a floodlight but only within its limited area of focus. A spotlight is more suited to lighting up objects and a floodlight is more suited to illuminating areas.
Spotlights are suited for highlighting paintings, in under-cabinet places for accentuating showpieces, lighting for bathroom mirrors and other places. Floodlights are meant for open areas and outdoors where focused lighting is not needed.
Light emitting diodes (LEDs), are small diodes that are integrated into LED lamps and fit effortlessly into an electrical circuit. Unlike incandescent bulbs, they do not have a filament that will burn out and do not get especially hot as they have a built-in heat sink that dissipates any heat produced during operation.
LED technology was a breakthrough in the world of lighting. It has quickly become the standard in the industrial vertical. As with every technology, education and understanding of the benefits of LED increases with each passing day. With it LED is quickly becoming the preferred choice for everyone.
When initially introduced, LED technology, like any new technology was considered expensive. As time progressed and the technology advanced the price of LED has dropped dramatically. Today LED lighting is still more expensive than traditional ligthing but the benefits definitely outweigh the cost. Life span, reduction in electricity costs and the environmental benefits are easily making LED the choice of the future.
Governments, both Federal and Provincial are working closely with consumers, residential, commercial and industrial to create rebate programs and various incentives to assist in eliminating older technology in favour of newer, more advanced and efficient technology. As LED technology continues to gain mass appeal, initial costs will continue to lower and increase long term savings.
To add to their existing efficiency, LEDs come with heat management capabilities to prevent them from heating up. While some of the energy is converted to heat in the process of lighting, a heat sink dissipates that heat away from the lamp in order to ensure the bulb does not burn and in the process, affect its components. Therefore LEDs do not run at high temperatures.
No, LED lamps provide cool light that is free of any harmful UV and infrared emission. Closely resembling the features of natural light, there is no flaw or discolouring effect on anything that falls under the light. The biggest benefit is has no detriment to the environment or most importantly, unlike traditional lighting, has no effect on the health of people who are exposed to it.
Electricity savings and energy efficiency are important parameters that help us choose the right lighting. The ever increasing cost of electricity is making LED lighting a necessity rather than choice. Today retail and commercial sectors are consuming tremendous amounts of electricity with their 24*7 usage. The replacement of conventional bulbs with compact LEDs brings immense savings in terms of cost, efficiency and employee health. LED lights are available in many variations that are perfectly able to fit into almost any application.
The quality of light emitted from LEDs is much superior to that of other conventional sources of lighting. Incandescent bulbs and CFLs emit Omni directional light; hence wasting a large amount of useful light through dispersement. LEDs emit directional light, which in essence means, it provides a focused light as required per the application. The end result is very little light dispersement. LED focuses the light to the area where the light is actually needed.
Ambient lighting is an all-purpose illumination that provides a comfortable level of brightness to the overall area without causing any glare. This type of lighting is in contrast to directional lighting. The source of lighting can be concealed but creates the required amount of visibility.
Task lighting is focused lighting where light is centred on a particular area. For example, hospital operation theatre lights used in surgery or work desks would require task lighting. LEDs produce directional lighting that increases the illumination in a particular area enhancing brightness at a particular spot. With focused lighting, the objects appear clear as higher contrast levels result in increased visibility. The most important aspect of LED is that they do not produce multiple shadows as they are point source or single source lighting and do not cause any strain on the eyes.
Accent Lighting is lighting that highlights a landscape or an object in a room. This lighting has a striking effect and adds to dimension of a room by highlighting certain aspects of a room design and decor. The lighting is able to enhance the aesthetic aspect of the area. For example, highlighting a picture or painting, LEDs produce concentrated light on the object without causing any reflection or glare.
LED Street Lighting is rugged and robust and is able to withstand all type of climate conditions while providing a uniform distribution of light without being affected by any external influence. The fixture is dust proof, water proof and comes with excellent thermal design. There are cases where it may be required to direct light behind the pole or to light up the pavement or footpath, which is provisioned in the fixture design.
The various options that are available for spaces like bedrooms, dens and bathrooms are spotlights, downlights, chandeliers, cove lights, table lamps, cupboard lighting, etc., and come in various color combinations. These can be easily controlled as per the requirement and mood. They are asthetically pleasing and look elegant, creating a cozy and relaxing feel. With the variety of options available today with LEDs, you can create the lighting environment of your choosing.
All conventional lighting fixtures can now be replaced with LEDs in offices, restaurants, for exteriors, balconies, lobby etc. LED lighting and fixtures for different business verticals are available in the market that can create the perfect lighting and ambience you desire.
Since LEDs contain zero mercury and do not contain any toxic material, they are extremely eco-friendly. LEDs are the most energy efficient light source produced today. They have the ability to save 90% more energy than incandescent bulbs and 40-50% more than CFLs. All this with a much longer life span. Incandescent bulbs are an extremely inefficient source of light. More electric energy is wasted producing light that creates a dramatic amount of heat lessening the life span of the product meant to emit the light. The carbon footprint is very high causing unintended damage to the environment and potentially long term health concerns for humans. LEDs are energy efficient, environmentally friendly and represent huge long terms savings.
The fastest growing segment in LEDs is retrofit. Retrofit allows customers to use existing fixtures for LED lamps by simply replacing conventional lamps with LEDs. No modification to the fixtures is required.
Retrofits available for LEDs across the board, whether lamps or tube lights the retrofit works perfectly without causing any unwanted difficulties. LED retrofits come in compact sizes and can fit into any fixture, small or large.
LED lighting is the technology of the future. It is 50% more energy efficient than CFLs. LEDs have a longer life span than CFLs, are more energy efficient, eco-friendly and do most importantly do not contain any mercury. LEDs are able to last upwards of 50,000 hours. Still, the initial capital cost is considered a big deterrent to many and that is the main reason why LED has not yet been fully adopted industry wide. Consumers are unaware of the long term benefits and find it difficult to invest into a new technology. However, the retail and commercial sector has been quick to adopt the technology because of the dramatic reduction in electricity costs and quick return on investment.
As LED technology continues to gain critical mass and a wide appeal, LEDs will become cheaper and more affordable. Already LED retrofits are gaining acceptance as they can be replaced easily without needing any modification in fixtures.
LEDs have become irreplaceable in sectors that require heavy usage such as BPO’s, IT & ITeS, hotels, restaurants and in applications such as street lighting, operation theatres etc. LEDs in home lighting segment will get a boost with technology becoming cheaper.
1. Energy saving- LEDs are the most energy efficient lighting solution available to date. CFLs provide 80% energy saving over an incandescent bulb while LEDs are 50% more energy efficient than CFLs.
2. Lifespan-Incandescent bulbs come with a life of approx 1,000 hours, CFLs provide a life span of around 5000 - 6,000 hours. LED bulbs can last up to 25000-50000 hours. LEDs work on semiconductors which have an infinite lifespan.
3. Environment friendliness- CFLs contain small amount of Mercury and electronic waste, disposing of them represents a becomes a possible hazard that has become regulated. LEDs on the other hand are eco friendly, as they are mercury-free.
4. Cost- CFLs are more expensive than incandescent bulbs, but cheaper than LEDs. Consumers have adopted CFLs worldwide and have become very popular. Because of the popularity, the cost of CFLs has gradually come down, making them more affordable to masses. LED based lighting is comparatively a new technology. However the capabilities of LED has grown exponentially in a very short period of time. The applications and availability have quickly dropped the price substantially and as acceptance and understanding of the tremendous benefits of LED become more prevelant, the pricing will continue to drop and LED will take over as the choice for everyone.
5. Quality of light- CFL emit Omni directional light, hence a great deal of useful light is dispersed and wasted. LEDs emit directional or focused light. The end result is little or no waste. LED beams the light specifically to the area where the light is actually needed.
6. Installation method- CFLs do not come with heat sink capabilities and tend to burn. LEDs being equipped with heat sinks technology have the ability to disperse heat. CFLs are sensitive to the temperature and tend to die in enclosed fixtures due to lack of cooler air. LEDs perform equally well in a colder terrain while the performance of CFL is affected by the external temperature.
