LED lights are designed to last for years and create less heat than other types of light bulbs. However, if the fixture is enclosed or not well ventilated, the heat can build up and cause the LEDs to fail prematurely. To fix this issue, ensure that the light fixture has air around it and is well ventilated.
Blue light glitches and refusal to turn on/off can be frustrating, especially when they are designed to fade over a long period of time rather than blow out and stop working. To troubleshoot LED lights, understand the underlying reasons and apply the suggested troubleshooting tips. Common causes for defective LED lamps include power fluctuations, dimmers, transformers, motion detectors, and more.
To troubleshoot LED lights, check the contact points of the fixture and follow the suggested troubleshooting tips. If LED lights only show one color (red, green, blue), it might be due to a loose cable, wrong power source, or a malfunctioning controller. Learn how to check and reset your LED lights and controller to restore their functionality.
Blue lights store a tiny bit of energy, so even when they’re off, they glow a little because of that remaining electricity. To remove energy by absorbing and removing the remaining electricity, change the LED to one with a different color and use a drop resistor. Blue LEDs run about 3.5 to 4V, and the rest (other than white) are about 3.5 to 4V.
In interior LED lights, make sure the engine is running for the settings to take effect. Ambient light setting may be set to off, as there may be a little current leaking through the electronics inside the BCM. Try putting a pull-up resistor to change the ambient lights’ brightness.

Why are my LEDs only red?
The device’s faint red glow is a consequence of its 12-volt power supply, which is inadequate to operate all channels due to the DC 24-volt rating.
Why can’t i focus on blue LED?
Blue light scatters more easily than most visible light, making it difficult for the eye to focus. This reduction in contrast may contribute to eyestrain. However, there is limited research to confirm that blue light directly leads to eyestrain. The long-term effects of blue light on human eye health are still uncertain, but there is consensus on its impact on the sleep-wake cycle. More high-quality studies are needed to confirm this.
Why are blue LEDs so bright?
Blue LEDs are noticeably brighter than red and green LEDs due to their higher current consumption. A 5 mA current will make red LEDs passable, but flashlight-level blue is more noticeable. However, designers may worry about using too much resistance and too little current, as users may not see the color. Blue LEDs also draw less power than red and green ones for the same brightness, making them suitable for battery-backed devices.
The “less expensive” part may be true in the past, but today, a search shows $0. 01468 for red and $0. 01572 for blue in 10K quantities, making it unlikely that 0. 1 cent will affect the final cost unless the device is super-cheap.
Why are some of my LED colors not working?
Light strips can display different colors due to uneven voltage distribution or faulty LED chips. To fix this issue, reset the strip and controller, and if the problem persists, replace the defective chip. Ensure to buy high-quality LED strips to avoid these issues. Dead LEDs can occur when certain sections or individual LEDs stop working due to weak connections, manufacturing defects, or improper handling. If a loose connection is the cause, fixing the connection can solve the problem.
Is having blue LED lights bad?
Prolonged exposure to blue light has been linked to an increased risk of retinal damage, as well as a range of vision issues, including macular degeneration, cataracts, and even eye cancer. Additionally, prolonged exposure to blue light has been associated with the development of growths on the clear covering over the white part of the eye.
Do blue LEDs use less power?
Blue radiation in LED technology offers two advantages: lower power consumption and increased efficiency in light output. From 2014 to 2018, the efficiency of blue LEDs increased from 130-140 lm/W to 200-210 lm/W, positively impacting lighting costs and the environment, especially in developing countries. Blue LEDs are used for indoor and outdoor lighting, solar-based applications, and electronic gadgets like TVs, computers, and mobile phones.
However, some studies suggest that blue light is unhealthy for humans, especially the eyes. Compliance with photo-biological requirements, such as IEC standards, is the main determinant of safety for LED lights.
Why are blue LEDs brighter than red?
The text discusses the differences in brightness between different colors of LEDs, highlighting the importance of considering these factors when testing them. Blue LEDs require a higher voltage than red LEDs due to their shorter wavelength photons, while green LEDs require more current to achieve the same brightness. Manufacturers also produce different LEDs with varying brightnesses for the same currents. The text suggests that it is better to play with the LEDs themselves to ensure a clear understanding of the perceived brightness.
To test each LED, the author created a custom PCB using three different sizes of LEDs: 0402, 0603, and 1206. The board included each footprint in parallel, and an 0805 footprint and plated through-holes for LEDs with legs allowed for testing any LED. This approach ensures accurate and reliable testing of LEDs.
Why doesn’t blue work on my LED lights?
In the event that the blue light fails to function when connected directly to a power supply, it is necessary to re-solder the older connection on the LED strip. The issue of RGB problems has been resolved; however, the RGB/W LEDs emit a faint glow, with the red light typically being the most prominent due to its lower power output. The sole remaining option is to procure a new 24V power supply for 24V tapes.
Is it bad to have blue light in your room?
Exposure to blue light before bedtime can disrupt sleep by suppressing the release of melatonin, a hormone that makes us feel drowsy. This disrupts circadian rhythms, making us feel alert instead of tired. Chronic misalignment of circadian rhythms can lead to negative health impacts, including metabolic disorders and mental health conditions like depression. Being mindful of sources of blue light and daily exposure levels can help reduce these risks. Many people work under artificial lights and constantly interact with electronic devices, so being aware of these sources can help strategically time exposure and avoid circadian rhythm disruptions.
Why do blue LEDs hurt my eyes?
Blue light, a high-energy, short-wavelength light, can penetrate the retina, the inner lining of the eye, leading to digital eye strain and potential retinal damage. Overexposure to blue light from LEDs and other artificial sources has been linked to these risks. Understanding the role and impact of blue light emission is crucial in assessing the safety of LED lights for eye health. Despite their energy efficiency and lifespan benefits, concerns have been raised about the potential impact on eye health due to the high levels of blue light emitted.
Is blue a good LED light color?
A recent study found that excessive white and blue light in a bedroom can negatively impact mood and sleep. Blue light has the most significant impact on mood, followed by white light. The use of blue or white lights can make the room feel energetic and unsettling before sleep. However, the issue becomes more complex with colored LEDs, as the light exposure before bedtime and early morning affects the biological clock.
Recent studies suggest that certain light frequencies can help with sleep and promote good rest. This article will explore how specific colors affect sleep and identify the most effective types of light for encouraging sleep.
📹 Philips LED Light Bulb – The Blue LEDs Inside
This Philips LED light bulb broke, so let’s take a look at what’s inside! Follow me on other Social Media! My second channel: …
I still have the original Philips L Prize light bulb with the metal base. The very first generation one. The one that has a weird yellow coating on the outside that really looks like a bug light. That thing was expensive too! It was close to $40.00 back in 2012. It has gotten run about 15 hours a day every day since 2012 and still works. A year later we picked up that version you are demonstrating and it lasted about 2 years being the porch light. Its really crazy how LED light bulbs have dropped in cost. Those really thick plastic bags are supposed to be reused. 😀
I have one of those earlier remote phosphor bulbs you mentioned with 3 plastic covers that come off. Blew my mind when i found our how white led’s were made, i had no idea they don’t actually exist, we just use phosphor conversion. I hear there are some that work with violet leds too, to get high CRI for professional photography and whatnot.
Remember do NOT buy low CRI 2700K lights. They are WAY too yellow to the point it goes towards orange. If you want warm white. Get a higher CRI version. Same with low CRI daylights. They are a bit bluer than the higher FRI ones. Also when you get light bulbs always look at the color temperature of the old CFL or LED bulb. And repeat, Do NOT buy low quality warm white LEDs. They have relatively low CRI and make everything pretty much look yellow. The higher quality warm white LEDs should not work as yellow. And the high quality daylight bulbs should not look as blue.
Hi good evening. Ah yes, the white envelope of the bulb I had seen that it had been cracked or cracked ? Ah yes when you remove after the small yellow basin. Behind there are 8 LEDs that make blue light ? But is it original blue light or UV blue light ? finally of the black light that there is, inside ? when you put the basin back, does it give a warm white ? Normal light ? Is it a fluorescent capsule ? Please ? Thanks.
