See our top picks if you're after new LEDs in our round-up of the best LED light bulbs. Flexibility & Curves – will twisting / bending LED tapes damage them? 3. Make sure the strips are turned off. These are designed to smoothly dim old-style bulbs in a circuit with a range typically between 200W to 1,000W. A week later two more quit working. If those strips are all powered by a 30W power supply, this will go into overload protection mode, which means it will turn on, realise it is overloaded and immediately turn back off again, then keep repeating this cycle. LEDs are designed to dissipate the relatively small amount of heat that they generate, compared with old-style bulbs. Most standard LED strips can be used in lengths up to 5m, powered from one end, with no voltage drop along the strip that will be visible to the human eye. The big giveaway is if there are multiple sections that appear to be a different colour, or more dim than the rest of the strip. half of my string of lights was not working. Tip If you cannot find the correct size of bulb to replace the burned-out ones, which is often the case, you can use a light tool that looks similar to a gun. What this means is that due to a manufacturing flaw or some mechanical damage during shipping or installation, one of the LEDs or components for a single section has come loose, resulting in a complete electrical disjoint for just that … If the embedded LED strip still does not light up, then the LED strips will need to be replaced. (some specialised strips can be used in 10m,15m or 20m lengths). Easy fix for some not for others. In such a case, you should then see that the Blue lights will light up, proving that they work – which means you have a bad connection somewhere else. Then, check that none of your wire connections from the converter have come loose, which is a common cause of many LEDs going out, flickering, or dimming. This guide covers troubleshooting for all LED strips that run on 12V or 24V. If the ceiling light then still remains dark, it is usually due to the following external conditions. Early failures (28%), flickering (12%), buzzing (5%) and radio interference (2%) were the main problems encountered. it seems my Nova outdoor lights are susceptible to water infiltration from where the wires enter at back, the water freezes and Severs the contact, causing the lights to go out. Make sure you check the wattage rating of the trailing edge dimmer to make sure it suits the wattage of the lights in the dimmer circuit (count up the total wattage of all of the bulbs in the circuit you are dimming). Failure of “LED Strip Lights” typically, it is heat induced metal fatigue. 24-volt strip lights are better for slightly longer runs, commonly in homes for under cabinet and staircase lighting or in RVs. This can be caused by static-electricity damage, or bending and twisting the strip too much, or being trod on, damaged in transit, a cheap poor-quality strip, or dry solder joints. Then when you turn them on, bam! More and more people are making the switch, as the technology has improved to allow for brighter bulbs that look almost identical to traditional light bulbs. And note that black is always positive (+) for RGB/RGBW strips. But the trouble is that this will damage the LEDs very quickly (usually within hours) and can be a fire hazard. There are a number of possible causes for this: This causes flickering and buzzing, and is usually down to using the wrong dimmer switch. If the LED strips aren't both coming up white when you set them to white. Well that means the Red LEDs within that section are faulty. In most cases here the only option is to replace that section of the strip. If it does, then you have a faulty power supply and will need a new one. My understanding is that the individual branches are in parallel whereas the lights in each branch is in series. Before taking this step, it’s worth attempting to touch or press down on the LEDs/resistors in the faulty section – in the best case possible, you may see that the light miraculously comes back on; in this case the problem is a dry solder joint, and if you’re capable of soldering you can repair this strip!

Here is a great video to work out how much strip you can put on a power supply: Are your LED strips working fine for most of their length, except for one section or a couple of sections within the cutpoints of the tape? You may have a faulty power supply. If the complete section between cutpoints is not working, this is a very similar problem to a damaged LED or resistor – most likely caused by a dry solder joint. But in every case, the first step is to find where the problem is located. They can be cut to specific lengths using just a pair of scissors along the cutlines, located every 1-2 inches. Incandescent and LED rope lights are available in 12, 24, or 120-Volt versions. For example, if you have 10m of LED strip that draws 5 watts per metre, the strip requires 50W in total (whether it’s two 5m strips or 10x 1m strips, it still adds up to 50W). so start by wiring the positive from the power supply to the black cable on the LED strip. This can, in rare cases, interfere with a DAB radio signal. If option A is true, with 24 volts going to a 12V strip, then yes the strips will still work. This can be caused by two things. Our top LED bulbs don't cost the earth either - we've found Best Buy LEDs and spotlights from £2.50. More than half haven't experienced any problems at all when fitting their LEDs. You have a 12V power supply going to 24V LED strips. This problem has two possible causes. I need to open up the metal side panel to locate the FAN/LED module. Therefore the issue is related to the cabling. Whether you need bespoke brightness-levels or a specific Kelvin rating for your colour temperature, it’s no problem. Or you can get another, say for example, 100mm section and solder this in – or you can use connector clips to clip in a new 100mm section. Temporarily turn off the power source. Can they be fixed? You can also scrape the dry paint off the LEDs with a fine knife. Dimming – how to control white and single-colour LED strip lights. In this case you should check the wiring again and make sure that the lamp is connected correctly.
