LED lights have many benefits and save a lot of electricity. However, when switched on, some LED lights and LED bulbs can take a while before achieving full brightness.
While this might cause significant inconveniences for users, it is not uncommon. Neighbours and friends may be annoyed at their kitchen lights for this unnecessary wait time!
This problem arrives unannounced at any time and can affect the light or the switch, but there’s nothing to worry about.
To ensure that your LED lamps turn on right after they are switched on, it is crucial to figure out what causes the delay in the first place. And in this guide, we will take you through some of the most common causes behind this issue. We will also tell you about the most efficient ways to tackle the problem on your own.
So, let’s dive in!
If the connections between the lights and switches are dirty or loose, they can affect the flow of electricity and delay the response time of your LEDs. That’s why hiring an electrician to clean and tighten all connections is important as soon as you observe the delay.
Power surges can damage sensitive electronic components like LEDs, causing them to malfunction or respond slowly. We’d strongly recommend investing in a quality surge protector to protect your lights and other appliances from power surges.
Some LEDs tend to overheat when used for long periods at high brightness levels. This can cause them to become dim or flicker, eventually leading to complete failure. But you can reduce the chances of these problems by optimising the brightness level. Aside from that, we’d suggest allowing a cool-off period for LEDs that have been running for too long.
However, if the bulbs are too old or have been used frequently for some time now, replacing them is the best way to eliminate the problem.
If any of the electronic components in your LED light or switch fails, it can cause the entire unit to malfunction. Hence, you should only purchase these units from reputable manufacturers offering warranties for hassle-free repairs and replacements.
If you do not install your LED lights or switches correctly, they may not function properly. So, ensure you hire a licensed professional when installing electrical fixtures or fittings.
For example, a LED light delay can occur if the LED fixture is too far from the switch or vice versa.
Traditional incandescent or fluorescent lights require a certain amount of heat to produce light, which is why the delay is considered normal for these fixtures. However, LEDs don’t need heat to produce light, meaning they can shine with full brightness as soon as they are switched on in ideal conditions.
That said, you may be surprised that an LED or light switch delay isn’t always a sign of malfunction. For instance, you may notice a power-up delay in certain LED lights because they are built differently.
Energy-saving lights, in particular, have a delay period, as they need some time to “warm up.” This should be mentioned in the product description or will be informed to you by the electrician installing it so that you don’t know it’s not a defect.
LED transformers in these lights can cause a delay of up to two seconds. As a result, the transformer circuit typically contains multiple capacitors that charge when the power is switched on and store this energy.
The transformer transfers the capacitors' output voltage to the high-quality LED light once fully charged. Some capacitors, however, have large storage capacities, so they take longer to charge. In essence, the extra charging time results in a delay in switching on.
You can avoid facing the delay by being careful while buying a LED fixture. Simply ensure that the light switch-on delay is less than 0.5 seconds. This is the maximum time most LEDs take to attain 60% brightness after being turned on.
Besides, the delay is hardly noticeable in these lights, which makes them ideal for areas like basements, staircases and porches where you need instant lighting. You will also find LED lights with a power-up time of 0.01 seconds, so consider going from them if “no delay” sits on top of your priority list.
Long story short, you should always read the package carefully to know about the power-up time. Don’t forget to ask the seller for the details if it is not printed on the package. Never purchase a light without knowing this specification; it may waste your money and leave you utterly disappointed.
It’s safe to conclude that switch-on delay in LED lights can be pretty annoying and get on your nerves. While some options might have a built-in delay, others may face electrical issues.
If you see that the above suggestions don’t solve the problem or have no prior experience working with lights, don’t delay calling the professionals.
Some delays may also be caused by problems in the wiring or power outlet, which trained electricians best tackle. And depending on your area, there may be strict regulations regarding conducting electrical repairs and installations, which you wouldn’t want to break.
