THE COLORED LED AND WHITE LED MARKETS
Whereas industry for colored (Red, Green, Blue) RGB LEDs is well established, industry for white LEDs remains growing. Why? When you consider industries that still count on white, non-LED lighting, such as televisions led board, automotive manufacturers, computer monitors, notebook computers, LCD backlights, etc., you are able to understand the push to end up being the leader in white LED manufacturing. Many folks are surprised a business would shun 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 in the marketplace, doesn't signify they must be on your immediate shopping list. In very simple terms, industry for colored and color-changing LEDs is mature. While engineers remain finding ways to create them brighter and better, the holy grail of the LED industry is in developing volume production of high-efficiency, high-brightness white LEDs.
It could be easier to think about colored LEDs (RGB) and white LEDs in terms of another industry: Automotive. RGB LEDs are like the inner combustion engine: Reliable, abundant, user friendly and manufacture, and fairly ripped in terms of the prospect of new or breakthrough technologies. There are plenty on manufacturers and each has their very own set of patents and "tricks of the trade" to greatly help give themselves some marketing leverage on the competition. White LEDs are like the choice energy industry for transportation: Quite varied, still relatively "new", still the need to be market proven, more costly, more difficult to manage. There are numerous manufacturers, each utilizing a different technology or combination of technologies to accomplish what they believe is the "another 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 had not been thought of previously. White LEDs, on one other hand remain developing technically and should not be shopped centered on cost alone. The requirement 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 need to be considered, building a quick and easy recommendation about transitioning to white LEDs is not possible. To get a jump start the future, consider every lighting source in each room and establish what it's primary purpose is. When you have done this, review these items to greatly help determine where on the priority purchase-list each replacement should be. Here are a few general guidelines to assist you determine if an LED upgrade is the right choice for you personally:
1.) Could be the lighting positioned in a home where in fact the primary resident is older or has mobility issues?
If the LED replacement produces adequate light levels, LED alternatives are ideal for use in homes where safety is a premier priority. Knowing that an ill or older person will not need to alter a burned-out light bulb again can offer peace-of-mind.
2.) Is initial cost a principal aspect in determining in the event that you will upgrade?
The present nature of the white LED market implies that prices are still relatively high, especially compared to traditional lighting. Being an early on adopter means paying a premium; are you comfortable with knowing you may have paid less for the exact same technology if you had waited?
3.) Could be the light positioned in bright daytime sunlight or an area of high heat?
High quantities of heat will noticeably shorten the lifespan of any LED, especially white LEDs. When considering LEDs, try to make sure that the fixture and the positioning permit adequate passive cooling to prevent color-shift and longevity issues. This can be a much bigger concern when contemplating retrofit bulbs versus considering a "total package" LED fixture and lamp.
4.) Are you needing to cut back heat output from a normal source of light?
In bathrooms, laundry rooms and small spaces, conventional lighting can produce uncomfortable heat. LED lighting is ideal for these areas simply because they produce no heat and because affordably illuminating smaller areas with LEDs presents much less of a challenge.
5.) Could be the lighting positioned 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 will break a light bulb filament and cold conditions that will result in a fluorescent tube to flicker are of no consequence to LED lighting, making these replacements a simple enough decision.
6.) Could be the brightness critical to the application form?
LEDs are directional naturally, so trying to meet a certain brightness expectation over a broad area is not the best use of LED lamps. The present crop of standard fluorescent tubes or high-bay lighting is going to be better for these applications.
7.) Are you attempting to retrofit a preexisting lighting fixture to allow for an LED replacement?
Most current lighting fixtures are created to capture and reflect just as much light as you possibly can from conventional light sources that produce light from all 360 degrees. Because LEDs emit very directional light, there are often many compromises that must be created by manufacturers in order to make LEDs "work" for the maximum quantity of retrofits. When possible, as opposed to retrofit bulbs think about a "total package" LED lighting fixture that has been designed from the ground around efficiently use LEDs.
8.) Could be the light output and quality of the LED version acceptable compared to your existing lighting?
With the range of lighting technology available (incandescent, fluorescent, LED, etc.) the only path to obtain a precise notion of how a lighting will perform would be to compare the light output or lumen and color temperature specifications as opposed to the wattage as is typical of most 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 available on foods, to greatly help consumers compare lighting.
9.) Will be the bulbs you're considering replacing difficult to get into or reach?
If they are, LED replacements are great candidates because once they're changed, you will more than likely not have to alter them again since LEDs do not "burn up" like a conventional bulb.
10.) Are you replacing all of the light bulbs in a specific area or perhaps an individual bulb?
Until 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, it is probable a hot color temperature and changing an individual reading lamp to LED with a cooler lighting temperature will not only be noticeable, but are often distracting.
11.) Does the power savings and/or return on investment (ROI) allow it to be worthwhile now?Prepare a power audit using free web calculators to ascertain the amount of money you'll save on energy and what the potential return on investment is. Just enter your energy rates, the sum total wattage of one's conventional lighting and the sum total wattage of the LED lighting that you will be considering and the calculator can tell you exactly the amount of money each technology will run you per year.
As you will see, every lighting situation is highly recommended individually against the above checklist. This can help you to ascertain LED upgrade plans that fit within both your financial allowance and your expectations. In general, LED lighting will continue to enhance in both output and efficiency annually just like the way the private computer market has evolved. What could certainly be a "middle of the street" LED lamp today, was totally possible considered a premium 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 whilst the technology improves will ensure a cushty transition to tomorrows lighting technology.
