There are lots of possibilities here, depending on the answers to these questions: 1. Or else the inrush current is too high for your breaker. If you don’t have a faulty power supply but have several power supplies on a breaker and it is tripping, then the inrush current is too high for that type of breaker. That way, you can see the whites and colours, and test brightness, colour temperatures and shades in real life. InStyle LED work with trade customers in mind. (some specialised strips can be used in 10m,15m or 20m lengths). Check the LED bulb manufacturer's website as they may have specific recommendations. I have done this successfully many times, and the strips worked perfectly afterwards. The same with option B: if +ve and -ve and are touching somewhere, then the strips will fail within hours and LEDs will be be damaged. However, LED bulbs are such low power that a small 'leak' of electricity like this can be enough to make them glow. If so, then you can either resolder, or simply split the solder with a Stanley knife so that the +ve and -ve are no longer touching. Buying multipacks, especially of LED GU10 spotlights, is often cheaper, too. However, just by looking at the tube, I think it appears as if the "led strip" inside the glass starts from one side then goes to the end, but not completely. You could experiment with it by getting a long test wire powered with 12 volts taken from your controller and work your way up and down the strip touching the wire to the connections for that color and try to isolate the bad section. After hearing from Which? the answer ended up being very annoying and simple. Getting an electrician to examine your circuits will be the best way to fix such a problem. 2. A mini lights string just won't come on or half-way lights up? How many LEDs are on the strip? When half a light strand is out it is usually a defect in the wire, apparently when a bulb burns out what happens is that the electricity bypasses that bulb to reach the rest of the lights, however if the channels in the wire are not working properly it will not allow the electricity to pass through to the rest of the string. They must not be coiled up in any way. How? Last week, one strip went out. You must check the cables, and re-wire any that are crossed over into the correct terminals. With this knowledge in mind, rebuild the system step-by-step, adding the controller (and extension cables if you have them) and see which component makes the Blue lights stop working. I replaced all of my under-counter fluorescent light strips with Connecting LED strips two years ago. This happens a lot when the painters come in and paint and do not know that there are LED strips where they cannot see them (inside a coving, for example). Of the 8 strips connected on two sides of my kitchen, two no longer work on one side, and one doesn't work on the other side. You may chose to get a larger power supply that can handle the total wattage required, so a power supply higher that the total wattage of all your LED strips. members to tell us about any LED problems they'd experienced in their homes. If you have an entire LED Strip segment illuminated but notice a section of the LED strip that remains dark, you may have an "open circuit" in one of the sections. LED strips are made up of 50mm / 100mm sections (sometimes other sizes), and wired in a way that means each section is a discrete, enclosed circuit (in other words, if a LED or resistor is damaged it will only effect the section of strip within the cutpoints). 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. Flexibility & Curves – will twisting / bending LED tapes damage them? Failure of “LED Strip Lights” typically, it is heat induced metal fatigue. This is a problem for LEDs that don’t need anything like that level of current in the circuit. the first pair of copper pads). LED bulbs require a much lower voltage (the force needed to make electricity flow) than traditional bulbs, so they have internal drivers (transformers) to reduce the voltage to the LED bulb. Try removing the flexible LED strip from the lighting channel, leaving only the embedded (hard) strip. OP: Why do my LED lights stop working half way through the same strip? It's one of those light strips that sticks under the tailgate and acts as another brake light. 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. Some have lifetime claims of up to 25,000 hours - that's more than 20 years if you have them on for three hours a day. I need to open up the metal side panel to locate the FAN/LED module. You can also scrape the dry paint off the LEDs with a fine knife. What voltage do you get if you measure the power supply output (or battery) voltage while the LED strip is running? This causes flickering and buzzing, and is usually down to using the wrong dimmer switch. Check the Wires. Hello, I ve used a led strip behind my TVs floating wall; however, certain leds are lighting a different color than the rest. Example they provide a spare fuse but no instructions on installing that spare. White LED tape – how to wire one LED strip, White LED tape – how to wire multiple LED strips. A regular strand of incandescent lights work, but whenever I plug in a strand of led lights in, only half of the strand works. My issue was a loose wiring after moving my PC around. Buy LED bulbs that state they are dimmable. 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. You can easily confirm this – if you set the strips to just Red then on that section they will be completely unlit, and if you set to Purple that section will show Blue only.

Single-Colour LEDs – large range of light colours in stock, Voltage – how to choose between 12V vs 24V LED strip lights, Voltage Drop – wiring LED strips to avoid reduced or uneven brightness. If you have a 24V power supply going to 12V strips, you can resolve this by getting a 12V power supply, or you can find a converter that converts 24V down to 12V (this would wire in between the power supply and the strip). Under powering your lights, such as using a 12-Volt driver or transformer for 24-Volt rope light, is likely to cause your lights to flicker, dim, or not light up at all. This field is for validation purposes and should be left unchanged. Then you know which one is faulty. If option A is true, with 24 volts going to a 12V strip, then yes the strips will still work. Water-Resistant LED Strips – what IP ratings can InStyle supply? Why? They will in fact be brighter than they should be, as you have double the power going through. If you think you might need an electrician, head to Which? Cutting & Soldering – can InStyle supply LED tapes pre-cut to length? 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. There are a number of possible causes for this: This causes flickering and buzzing, and is usually down to using the wrong dimmer switch. My boss found some 8ft t8 LED lights in bulk for pretty cheap, so I bypassed the ballasts in all the hanging ceiling lights (probably about 40 of them) and replaced them with the LED bulbs. You may even smell burning and this could be a fire hazard. We investigated LED lifetime claims in 2015, leaving hundreds of bulbs on for up to 15,000 hours, and also switching them on and off 10,000 times. Temporarily turn off the power source. This can be caused by two things. The flickering you see is the drivers in the LED bulbs adjusting the voltage to suit the LED. Let’s imagine that it’s the blue cable that is not working. NOTE: These troubleshooting instructions apply to LED strips from any manufacturer/supplier, not just strip lights purchased from InStyle LED. This can, in rare cases, interfere with a DAB radio signal. However, LEDs work differently to old-style light bulbs, and this can cause some issues when fitting them into older circuits. According to our survey, 90% of members who have LEDs in their home are happy with their bulbs and the quality of light they produce. Everyone will have a different name for their host co… That indicates those LED's are OK. Mark the good section and then try another section. – we have seen and solved almost every LED issue and scenario. My understanding is that the individual branches are in parallel whereas the lights in each branch is in series. Your home is likely to have a ‘leading edge’ dimmer. (The only part we don’t refund is carriage costs.). 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. If your first strip lights up white, but your second strip doesn't light up at all, or displays a color other than white, then we've got a bit of an issue and we'll need to look a little closer at these connections, which can be finicky to work with sometimes. They can get splashes of paint (or more!) Sometimes the cables can be touching, which can create unpredictable results. All of our goods in stock, and samples can be shipped for next-day delivery. You can do this by swapping the full strip. An LED strip light is typically half an inch (10-12 mm) in width, and up to 16 feet (5 meters) or more in length. Therefore the issue is related to the cabling. Just like finding an LED that is open except not looking for the LED's to turn on, but will increase slightly in brightness. The best start is to buy high-quality LEDs. The string recepticle is the logical location but it appears to be difficult to open without destroying the casing.

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. It’s also why they don’t overheat and last so much longer than traditional bulbs. One of the most common reasons for early burnout of LEDs, according to the industry experts we talked to, is putting LED bulbs into light fittings that still have some old-style light bulbs in them. And note that black is always positive (+) for RGB/RGBW strips. Only ever test strips when they are uncoiled. Works best in a slightly dark room.

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 … (e.g., when you select Orange, a 50mm or 100mm section shows Green only.) Or perhaps your project will allow you to reduce the amount of strips onto that power supply. If Red and Blue cables are touching, for example, then you’ll need to separate them so the connections are pure and without interference. This year, however, a bunch of the bulbs did not light up, right in the middle of them all -- as my wife quickly informed me. If your LEDs are flashing in a regular, consistent sequence (e.g., on for 1 second, off for 1 second, then on for 1 second again), then your power supply is overloaded! Sixty-bulb LED Christmas lights are built from two half strings of 30 bulbs each. Yes, the LED Keeper can find the culprit. 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? If you have extended the cable with a cable connector you must also check those connections too. Feature Lighting – how to create accent lights & highlights with LEDs. the same thing happened to me. Or if you have an output cable, the output +ve and -ve may be touching. But the trouble is that this will damage the LEDs very quickly (usually within hours) and can be a fire hazard. So you have two sides: the glass side and the metal side. I have a set of Christmas lights for which the second half doesn't light up. Avoid mixing LEDs and old-style (incandescent, halogen or CFL) bulbs in the same fitting. For example, if you switch from 4 x 60W bulbs in a circuit to 4 x equivalent brightness 9W LEDs, your total wattage has gone from 240W to 36W.
