Compared to fluorescent lights, HIDs, and other lamps, LED work lights offer a large potential for energy savings (up to 90%). But to what extent is this promotional material?
How can you choose items that really save money and energy as promised?
The financial and energy savings that some LEDs claimed have in fact been achieved. However, LEDs are only worthwhile as an investment when they deliver on their promises.For LED work lights, the industry norm is 3%. The failure rate for many building owners and facilities managers is 20% or more, however. 20 out of every 100 lights may fail and need to be changed due to the high failure rate. (Replacing broken lights may take longer since they may be dispersed around the structure.)
There are four causes of early LED work light failure.
The high failure rate has several causes, but many different things contribute to it most of the time. The four reasons why LED work lights malfunction and how to avoid them are listed below.
1. Using subpar materials
Commercially available LEDs are made up of a number of different parts, and the way these parts interact usually determines how well an LED performs. If the LED lamp is to operate correctly and provide an adequate amount of light, all of its components—from the kind of lens to the heat sink and the chips and power sources that produce light—must be made to endure.
Issues with the material quality; if a lamp lacks these, it is prone to malfunction. Use the LED driver as an example. For the LED to operate, the driver transforms AC power into DC electricity. Direct current is required for LEDs, although alternating current or direct current may be used for incandescent bulbs. If you construct the driver from low-quality parts, the LED might malfunction, necessitating the purchase of a new light to replace the one that should last for years (or decades). The heat produced by the drive may be difficult to remove and lead to malfunction if the proper drive is not employed. The LED flickers because of this; this is a warning indication of a failing driver.
What are the telltale signs that an LED light is constructed of high-quality components?
LEDs with adequate heat dissipation may cost more and/or be somewhat heavier. Inquire about chip size; bigger chips provide more light and better resistance to current fluctuations, while smaller chips offer less light and worse resistance. Check the paint or powder coating on the luminaire; if it is not applied properly, additional (those unseen) components (which may be inexpensive) may be and will be quickly integrated.
2. Insufficient light testing
Find out from the manufacturer how LED work light testing is done. Before shipping, some manufacturers thoroughly test the finished LED work lights.
The conscientious maker will install LED lights and lamps in a designated room for up to 10 days, test them by frequently turning them on and off, and leave them on for extended periods of time.
As solid-state electronics, LEDs are comparable to TVs or other consumer electronics in that they tend to fail sooner if they are destined to fail. Before the lamps are shipped, manufacturers can identify flaws by thoroughly testing the LEDs.
There are four causes of early LED work light failure.
3. The temperature is out of whack
Check the light after installing the LED in a closed fixture. LEDs shouldn't be installed in securely sealed fixtures unless they have been given the all-clear for usage in confined environments. The lamp will burn out before its time if the heat from the radiator cannot be removed.
Keep in mind the surroundings at the same time. The degradation of LED lights is accelerated by increased ambient temperature. Why? due to the exponential decline of the LED's brightness with time and temperature.
Continuous usage of LEDs in high-temperature situations depends on effective heat management. Due to their very poor thermal protection, LED lights are more vulnerable to breaking at colder temperatures.
4. Counterfeit lamps
Some LED lighting products resemble well-known brands in terms of appearance, and in some cases they even share the same marks, part numbers, logos, and packaging. These subpar copies are often created and designed without taking security, trademarks, or patents into account.
