LEDs are in the trend now. While LED bulbs are highly energy efficient and have long life, when you want to change over to LED lighting at home, office, public buildings or other spaces, try to get the best financial and operational benefits out of the replacement project. All LED manufacturers claim that their LED lighting products have more than three or five years? lifetime, hence, your replacement plan should be done with good planning so that your return of investment (RoI) is shorter than you can expect.
Survey is must
Do a well planned survey of the LED lights that are available in the market, particularly of the major brands or the good local companies. LED bulbs are currently available in many products such as replacements for 40W, 60W, and 75W traditional incandescents, reflector bulbs often used in recessed fixtures, and small track lights.
Next assess your requirements; where the changes in lighting are required, and what type of lamps are needed. The illumination will vary between the darker areas than the well-lit areas and the outdoor spaces.
Prioritise the most needed spots
Since LED bulbs and tubes are expensive than the traditional ones you will replace, you may want to replace a few and not all in the first phase, so prioritise the most needed areas. According to the US Department of Energy, by replacing your home’s five most frequently used light fixtures or bulbs with LED bulbs models that have earned the Energy Star, you can save a huge amount over a year. Energy Star-qualified LED lights use only 20%?25% of the energy and last up to 25 times longer than the traditional incandescent bulbs they replace. LEDs use 25%?30% of the energy and last 8 to 25 times longer than halogen incandescents.
In the first phase, you may replace your least efficient types of lighting and/or the lights used for the long hours. But to save energy costs, in the long run, have LED lights for all your requirements and areas. There are incentive programs in some states/countries; find details about them and avail benefits of these schemes.
Save a little more with lighting controls
To save even more of energy, and on your energy bills, consider using lighting controls like occupancy sensors, sensors that dim artificial light as sunlight enters a room, etc, with your LED lighting.
Again these control systems can be expensive, so you may want to prioritise the areas where you need them. Occupancy sensors are good for the bathrooms and bedrooms, where lights will be on and off sensing the occupancy of the people. May of us have the habit of leaving the lights on when we leave a room. The occupancy will take care of this bad habit and help us save more money on our electricity bills.
Use LED light in difficult areas
While prioritizing the areas for LED lighting, do include the difficult areas where it is a problem to reach out, and hence, difficult to change a burnt out bulb. Since LEDs have much longer life, it will save from changing these bulbs for a couple of years, at least. With LEDs lasting over 40,000-50,000 hours, the frequency and cost of replacing lights in an inconvenient place will be reduced.
For the best operational benefits
For operational benefits, you must know what should be the lumens of your LED lights. LED lighting is measured in lumens, while traditional lighting is measured in watts. LED lighting has direct stream of light beaming from its fixtures and its optics can be adjusted to point more accurately at the target spot. This information will help to make your lighting system more efficient. So basically, you should check three features of LED lighting?the lifecycle, temperature, and color of fixtures.
