Whereas the marketplace for colored (Red, Green, Blue) RGB LEDs is well established, the marketplace for white LEDs continues to be growing. Why? When you think about industries that still rely on white, non-LED lighting, such as televisions, automotive manufacturers, computer monitors, notebook computers, LCD backlights, etc., you can understand the push to become the leader in white LED manufacturing.
Lots of people are surprised that 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 that you can buy, does not mean that they should be on your own immediate shopping list. In 100 watt high bay led lights , the marketplace for colored and color-changing LEDs is mature. While engineers are still finding ways to make them brighter and much more efficient, the holy grail of the LED industry is in developing volume production of high-efficiency, high-brightness white LEDs.
It may be simpler to think about colored LEDs (RGB) and white LEDs regarding another industry: Automotive. RGB LEDs are just like the internal combustion engine: Reliable, abundant, simple to operate and manufacture, and fairly well toned in terms of the potential for new or breakthrough technologies. There are lots on manufacturers and each has their own set of patents and “tricks of the trade” to greatly help give themselves some marketing leverage over the competition. White LEDs are like the alternative energy industry for transportation: Quite varied, still relatively “new”, still needing to be market proven, more expensive, more challenging to control.
There are lots of manufacturers, each using a different technology or mix of technologies to accomplish what they believe may be the “the next big thing.” Following this 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 was not considered previously. White LEDs, however remain developing technically and should not be shopped predicated on cost alone. The necessity for quality and longevity is what fuels the further research and development into white LEDs.
11 THINGS TO CONSIDER IN DETERMINING LED UPGRADES
Because there are so many variables that require to be considered, making a quick and easy recommendation about transitioning to white LEDs isn’t possible. To acquire a jump start on the near future, consider every lighting source in each room and establish what it’s primary purpose is. Once you have done this, review the next what to help determine where on the priority purchase-list each replacement should be. Below are a few general ideas to help you determine if an LED upgrade is the right choice for you personally:
1.) May be the lighting located in a house where the primary resident is older or has mobility issues?
If the LED replacement produces adequate light levels, LED alternatives are ideal for used in homes where safety is a top priority. Realizing that an ill or older person will not need to change a burned-out light bulb again can offer peace-of-mind.
2.) Is initial cost a primary factor in determining if you are going to upgrade?
The existing nature of the white LED market means that prices are still relatively high, especially in comparison to traditional lighting. As an early adopter means paying a premium; are you comfortable with knowing you could have paid less for the same technology in the event that you had waited?
3.) Is the light situated in bright daytime sunlight or a location of high heat?
High degrees of heat will noticeably shorten the lifespan of any LED, especially white LEDs. When contemplating LEDs, try to ensure that both fixture and the location allow for adequate passive cooling to avoid color-shift and longevity issues. That is 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 the traditional light source?
In bathrooms, laundry rooms and small spaces, conventional lighting can produce uncomfortable heat. LED lighting is ideal 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 may break a lamp filament and winter that can result in a fluorescent tube to flicker are of no consequence to LED lighting, making these replacements a simple decision.
6.) May be the brightness critical to the application?
LEDs are directional by nature, so attempting to meet a particular brightness expectation over a broad area is not the very best usage of LED lamps. The current 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 possible from conventional light sources that produce light from all 360 degrees. Because LEDs emit very directional light, there are often many compromises that must definitely be made by manufacturers in order to make LEDs “work” for the best amount of retrofits. When possible, rather than retrofit bulbs consider a “total package” LED lighting fixture that is designed from the bottom up to efficiently use LEDs.
8.) Is the light output and quality of the LED version acceptable in comparison to your existing lighting?
With the variety of lighting technology available (incandescent, fluorescent, LED, etc.) the only way to get an accurate idea of how the lighting will perform would be to compare the light output or lumen and color temperature specifications instead of the wattage as is typical of all of us raised with traditional lighting in the home. The US 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 access or reach?
If they are, LED replacements are great candidates because after they are changed, you will likely never have to change them again since LEDs do not “burn out” like a conventional bulb.
10.) Are you currently replacing all the light bulbs in a particular area or just an individual bulb?
Unless you know the color temperature of all lighting in the area, play the role of consistent in whatever lighting technology you choose. 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 can not only be noticeable, but can also be distracting.
11.) Does the power savings and/or return on investment (ROI) ensure it is worthwhile at this time?Prepare an energy audit using free web calculators to determine how much money you will save on energy and what the potential profits on return is. Just enter your time rates, the full total wattage of one’s conventional lighting and the total wattage of the LED lighting you are considering and the calculator will let you know how much money each technology can cost you per year.
As you can see, every lighting situation is highly recommended individually against the above checklist. Doing so will help you to determine LED upgrade plans that fit within both your allowance and your expectations. Generally, LED lighting will continue steadily to improve in both output and efficiency every year like the way the non-public computer market has evolved. What could be considered a “middle of the road” LED lamp today, was very likely considered reduced product a 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 comfortable transition to tomorrows lighting technology.
