How to distinguish between good and bad quality LED lights

You may wonder how to distinguish between good and bad quality LED lights. Before you buy one, there are a few things you should look for. Brightness, Lifespan, Color temperature, Resistor size, and price are just a few. To make the process easier, we have summarized the features of good and bad LED lights. Hopefully, this information will help you make the right decision!


Choosing the right LED light is important for many reasons, including its brightness. In general, a light with a high CRI will give you brighter colors, while a low CRI will give you a less-than-ideal color rendition. Here are some tips to help you decide what color you need from your new light. You should also look for safety marks on the package. The Regulatory Compliance Mark (RCM) indicates that the light source has passed safety testing and is compatible with the Australian Government’s National Equipment Registration System.

First, look for the CRI rating, which measures color accuracy. In general, CRI of 80 or 90 is considered good. Compared to incandescent bulbs, LED lights with a CRI of 80 or 90 are considered good. However, there are certain LEDs with a low CRI that produce a brighter, clearer, and more precise white light. However, CRI is not nearly as important as wattage or color temperature for choosing the best LED light for your needs.

Another factor to consider when choosing LEDs is their construction. A light that lasts 50000 hours is not necessarily a good buy. Chinese LED manufactures typically cut corners when making them, often leaving the components and paint inferior. Hence, the warranty only covers a small percentage of the working hours. However, this may not be enough for commercial use, so look for a warranty of at least ten percent of the total working hours.

In addition to lumens, LEDs are rated by color temperature. High-lumen LEDs produce bright whites that mimic natural sunlight. High-lumen LEDs are referred to as Daylight, and are best suited for bathrooms, basements, and kitchens. These are also suitable for accent lighting and reading. Finally, lower-lumen LEDs are known as soft white or warm white, and they give off a yellowish glow.


If you have ever bought LED lighting for your outdoor decorations and security, you know that they are durable. Some manufacturers boast of up to 50,000 hours of life. While this is an impressive number, it is worth remembering that LED lights require a good heat dispassion. You should always look for aluminum heat sinks, as thin ones cannot transfer heat effectively. Some manufacturers use plastic or other materials instead. Also, look for the weight of the LED, as a heavier LED means higher quality.

LED components such as the drivers, circuit boards and yellow phosphor are expensive. Non-branded Chinese LED drivers usually use regular capacitors, which can only work for 1000 hours at elevated temperature. Charlston Lights’ LED drivers are designed to work for a decade, so they should provide high output for a relatively low price. The LEDs should be bright and have excellent color rendering. They can be installed anywhere from the kitchen to the drawing room.

The next thing you should look for in a LED is the heat management. While LEDs do not produce as much heat as other light sources, they do experience lumen depreciation. That means that their brightness reduces over time. This is important, because the higher the temperature, the less efficient the LEDs will be. Furthermore, cheap LED bulbs are more likely to break down and be of low quality, resulting in lower output.

Another thing you should look for is the colour temperature. This refers to the Kelvin color temperature scale. In general, a high CRI will produce whiter light, while a low CRI will give you a light with a bluer hue. You should always test a single LED before buying more than one. You should also aim for a CRI of 80 or more if you’re buying LEDs for task lighting.

Color temperature

When purchasing LED lighting for your home, you’ll want to be as careful as possible. One of the most important things to look for is the CRI (Color Rendering Index) rating. The higher the CRI, the better the light will be for distinguishing colours. Before buying an LED light, however, be sure to test one before buying more. If possible, find a light that has a CRI rating of 80 or above. In general, a 90+ CRI rating is considered ideal for task lighting.

The color temperature of LED lights is another crucial factor to look for. The color temperature refers to the temperature at which the light will appear. LEDs with higher temperatures produce cool, yellow light while LEDs with lower temperatures produce warm, natural light. For optimal illumination, choose LED lights that are labeled “Daylight” or “Soft White.”

While LEDs are often characterized by a warm, white light, they have a high color temperature and can fool the eye into thinking objects are different colors. Many artists have even observed this phenomenon in their work. It’s all part of the process of making an LED light. In this article, we’ll discuss a few of the most important aspects of LED quality. And don’t forget to check the price tag! You can always return the defective light.

Keep in mind that a higher temperature is not necessarily better for LED lighting. They should be shielded and reinforced to resist high temperatures. This is because high temperatures can damage LED lights. The light can eventually get dull and flicker and lose brightness. Lastly, LEDs should be placed in an environment where temperatures are low. The higher the temperature, the higher the risk of damage to the fixtures. A high temperature is not ideal for LED lights, and high temperatures can reduce the output of white light.

Resistor size

Resistor size is one of the primary differences between good and bad LED lights. The size of the resistor is determined by the forward voltage and power supply values of the LED. The values can vary widely, but a typical example is a blue LED that requires a 290-ohm resistor to work properly. A good example of a bad LED is one that has a forward voltage of 3.2V and uses a 290-ohm resistor.

When choosing an LED, pay special attention to the resistor size. Resistors are the most expensive parts of the LED, and the one that limits the forward current should be matched to the LED’s power rating. To make sure that the LED is the right resistor size, measure the forward voltage of the power supply and look for the corresponding resistance values. The yellow LED requires a 48-ohm resistor, while red LEDs require a 410-ohm resistor.

Some resistors are too large or too small, which is dangerous. LEDs can burn or break if they do not have the correct resistance. Using a 3.3-ohm resistor will damage the LEDs. A good resistor is about the same size as a half-watt resistor. The wattage of a good-quality LED will depend on the resistor size.

You can find the right resistor size by using a resistor calculator. Standard resistor sizes are available from component distributors. If you don’t know the correct resistor size, you can use the online calculator provided by Digikey or Mouser. You can also try using a resistor calculator from Digikey or Farnell/Newark. These two component suppliers are trusted for their high quality LEDs.

Energy efficiency

To know which LED light is good, first decide on the type you’re looking for. Then, look for the manufacturer. This step is extremely important because LED manufactures in China are notorious for cutting corners and producing inferior quality products. Look for paint quality, as this could be a sign of cheap components or poor construction. You should also consider the manufacturer’s reputation and focus. Once you’ve decided, look at their website to see if they’re listed on any reputable consumer rating sites.

LEDs have a CRI rating, which indicates how accurate the light they emit is. The higher the CRI, the better. Try a single LED bulb before buying more. Look for bulbs with CRI values of 80 or more. For task lighting, choose a high-CRI bulb. Alternatively, consider buying LED bulbs that are higher than 80. If you’re still not sure, try a sample of each before buying several.

Besides lumens, other characteristics of LED bulbs also matter. A high-quality LED bulb should be able to produce bright white light, which resembles sunlight. A low-priced LED light, on the other hand, uses leftover LEDs, which usually have a pink or greener hue. In these cases, the issue may not be the color temperature, but rather with quality control.

Another important factor to consider is the driver. If an LED light doesn’t have a high-quality driver, it will heat up frequently and eventually fail before its lifetime rating. You should also avoid buying cheap LED lights, since these will allow more power to pass through than recommended. A low-quality driver can also lead to heat problems and gradual damage to the circuit board components. The end result will be a less-than-optimal LED light.
