The Lazy Man’s Guide To Led Lights

Whereas the market for colored (Red, Green, Blue) RGB LEDs is well established, the market for white LEDs is still growing. Why? Once you think of industries that still rely on white, non-LED lighting, such as for example televisions, automotive manufacturers, computer monitors, notebook computers, LCD backlights, etc., it is possible to understand the push to become the leader in white LED manufacturing.

Many people are surprised a business would avoid a revenue generating opportunity that converting a home or business to LED would create. However, just because replacement white LED bulbs and retrofits are finally available to buy, does not mean that they should be on your immediate grocery list. In very simple terms, the market for colored and color-changing LEDs is mature. While engineers remain finding ways to make them brighter and much more efficient, the ultimate goal of the LED industry is in developing volume production of high-efficiency, high-brightness white LEDs.

It may be simpler to think of colored LEDs (RGB) and white LEDs when it comes to another industry: Automotive. RGB LEDs are just like the internal combustion engine: Reliable, abundant, simple to operate and manufacture, and fairly well developed with regards to the potential for new or breakthrough technologies. There are lots on manufacturers and each has their very own group of patents and “tricks of the trade” to help give themselves some marketing leverage over the competition. White LEDs are just like the alternative energy industry for transportation: Quite varied, still relatively “new”, still having to be market proven, more costly, more challenging to manage.

There are various manufacturers, each using a different technology or mix of technologies to accomplish what they believe may be the “another big thing.” Third , analogy, RGB LEDs are mature enough to compete on cost alone and the drop in costs is what fuels new applications for colored LEDs that had not been considered previously. White LEDs, on the other hand remain developing technically and really should not be shopped based on cost alone. The necessity for quality and longevity is what fuels the further research and development into white LEDs.


Because you can find so many variables that require to be considered, making a fast and simple recommendation about transitioning to white LEDs isn’t possible. To obtain a jump start on the near future, consider every lighting source in each room and establish what it’s primary purpose is. After you have done this, review the following items to help determine where on the priority purchase-list each replacement ought to be. Below are a few general guidelines to help you determine if an LED upgrade may be the right choice for you personally:

1.) Is the lighting located in a home where the primary resident is older or has mobility issues?

If the LED replacement produces adequate light levels, LED alternatives are perfect for used in homes where safety is really a top priority. Knowing that an ill or older person will not need to change a burned-out lamp again can provide peace-of-mind.

2.) Is initial cost a primary element in determining if you’re going to upgrade?

The current nature of the white LED market implies that prices remain relatively high, especially in comparison to traditional lighting. Being an early adopter means paying a premium; are you comfortable with knowing you might have paid less for exactly the same technology in the event that you had waited?

3.) Is the light situated in bright daytime sunlight or an area of high heat?

High levels of heat will noticeably shorten the lifespan of any LED, especially white LEDs. When considering LEDs, try to make sure that both fixture and the positioning enable adequate passive cooling in order to avoid color-shift and longevity issues. This is usually a much bigger concern when contemplating retrofit bulbs versus considering a “total package” LED fixture and lamp.

4.) Are you needing to reduce the heat output from a traditional light source?

In bathrooms, laundry rooms and small spaces, conventional lighting can produce uncomfortable heat. LED lighting is great for these areas since they produce no heat and because affordably illuminating smaller areas with LEDs presents much less of a challenge.

5.) May be the lighting located in an area of rough service or environmental extremes?

Garage door openers, unheated/cooled utility rooms and outdoor workshops place extreme demands of lighting equipment. Vibrations that can break a lamp filament and cold temperatures that can cause a fluorescent tube to flicker are of no consequence to LED lighting, making these replacements a fairly easy decision.

6.) May be the brightness critical to the application form?

LEDs are directional by nature, so trying to meet a specific brightness expectation over a wide area is not the very best use of LED lamps. The existing crop of standard fluorescent tubes or high-bay lighting will probably be better for these applications.

7.) Are you trying to retrofit a preexisting lighting fixture to support an LED replacement?

Most current lighting fixtures are made to capture and reflect as much light as you possibly can from conventional light sources that produce light from all 360 degrees. Because LEDs emit very directional light, you can find often many compromises that must be made by manufacturers in order to make LEDs “work” for the greatest amount of retrofits. When possible, rather than retrofit bulbs look at a “total package” LED lighting fixture that has been designed from the bottom around efficiently use LEDs.

8.) Is the light output and quality of the LED version acceptable in comparison to your existing lighting?

With all of the lighting technology available (incandescent, fluorescent, LED, etc.) the only method to get a precise idea of the way the lighting will perform would be to compare the light output or lumen and color temperature specifications rather than the wattage as is typical of most folks raised with traditional lighting in the house. THE UNITED STATES Department of Energy has devised a standardized “lighting facts” label similar in concept to the nutrition label found on foods, to greatly help consumers compare lighting.

9.) Will be the bulbs you’re considering replacing difficult to gain access to or reach?

If they’re, LED replacements are great candidates because once they are changed, you’ll likely never have to change them again since LEDs usually do not “burn up” like a conventional bulb.

10.) Are you currently replacing all the light bulbs in a particular area or just a single bulb?

Unless square led high bay lights know the colour temperature of all lighting in the room, try to be consistent in whatever lighting technology you select. For instance, if your room uses primarily halogen lighting, chances are a warm color temperature and changing an individual reading lamp to LED with a cooler lighting temperature will not only be noticeable, but may also be distracting.

11.) Does the energy savings and/or return on investment (ROI) make it worthwhile at this point?Prepare an energy audit using free web calculators to determine how much money you will save on energy and what the potential return on investment is. Just enter your time rates, the total wattage of one’s conventional lighting and the total wattage of the LED lighting that you are considering and the calculator will let you know exactly how much money each technology will cost you per year.

As you can see, every lighting situation should be considered individually against the above checklist. Doing so will assist you to determine LED upgrade plans that fit within both your budget and your expectations. In general, LED lighting will continue steadily to improve in both output and efficiency each year similar to the way the non-public computer market has evolved. What could possibly be considered a “middle of the road” LED lamp today, was more than likely considered a premium product per year or two ago. Prioritizing your LED lighting purchases so that the basics are covered first and delaying your more demanding lighting requirements because the technology improves will ensure a cushty transition to tomorrows lighting technology.
