Ceiling lights can be installed on the surface of ceilings, which making the installation methods more flexible. The power of our LED ceiling spotlights ranges from 5W to 50W. The beam angle can be selected from narrow/medium/wide.

LED MR16 Lamp

LED MR16 light sources are most widely used LED lighting products worldwide which can be used in any general indoor place. 

They are mainly used to replace other MR16 light sources, such as MR16 metal halide lamps. The LED MR16 light lamp has a longer life than the traditional MR16 light source and is more environmentally friendly and energy-saving.

These LED MR16 light sources can match with the MR16 fittings,so it is easy to keep current MR16 trim and to use LED MR16 lamps.

MR16 Fixture

MR16 fitting can match MR16 light source. DGT has variety of lighting fitxure of MR16, such as   fixed/adjustable/deep hole anti-glare ones.

Also, they can be made in different styles and patterns. Our MR16 outer ring roughly has openings φ65mm/φ75mm/φ90mm. More, there are also 1 head/2 heads/3 heads/4 heads MR16 trim.

About the LED color temperature

People in general associate the LED color temperature with either warmness or coolness. The cool LED light color temperature is common for LED bulbs that people attach near the windows or on the ceilings.

As a result, people perceive these LED light gradation temperatures in different ways. “Institutional” and “sterile” are two words that people often associate with the cooler LED color temperature. After all, many offices and institutional buildings are using these coloring systems for their LED products to improve their employees’ focus and concentration.

In contrast, people who use adjectives to picture cooler-tempered light bulbs tend to view the warmer LED color temperature as “not bright enough”. Some of these people often get frustrated because their warm-toned light bulb products seem to not work properly, while in fact, their yellowish or pinkish hues are their natural characteristics.


These people add to their confusion by complaining the lights are suddenly becoming too bright when other people change the LED color temperature chart, from the previously warmer-toned to this time’s cooler-toned. In reality, the color temperature LED lights differ from each other, which we note as Kelvin (K) and CCT.

Furthermore, even lamps with the same K or CCT measurements can have different looks, settings, and more. In this article about LED color temperature, we will guide you through the color temperature LED lights products that you can recognize. First of all, we’ll begin by explaining the all-about of LED light color temperature.

What does it mean by a LED coloring temperature?

A LED lighting color temperature has close correlations to a black body. A black body itself is an inanimate object that absorbs every radiation that results from no triggers from the inside or outside parts of lamp anatomy. In resulting in a certain color temperature LED lights range, a black body even disregards the LED lighting color temperature angles.

A Kelvin (K) measurement is the output that states how much the black body absorbs the lighting’s radiation. Each heating from the black body will result in different color glows, which we define, categorize, and classify under the area of LED’s color rendering.

In the end, the renderings can set up the mood and ambiance in any place. In some cases, these different coloring settings can even regulate the hormones in a person. So, those things become the reasons why understanding the different LED color temperature chart becomes important.

Here, in DGT Lighting Co. Ltd, the lamp’s coloring temperature even becomes one of the elements that we refer to as the “adjustable color temperature LED”. After all, we often receive requests to control the lighting’s colors and temperatures to some extent.

We refer to such practices as the tuning practice. In doing so, we make the jobs of changing between the 3000K color temperature LED light products and the 4000K LED products (or vice versa) become more effortless and less time-consuming.

What does it mean by Kelvin?

In a LED bulb color temperature world, Kelvin is a measurement of a lamp light’s colors’ temperature. We define such things  as CCT.

As for the more practical definitions and applications, we see Kelvin as the measurement for a lamp’s CCT in stores that sell LED products. The stores often categorize their lamp products as either daylight, natural, or soft whites. Then, the store owners and staff place the products with gradations that are identical to each other in the same lighting category.

However, we will begin to see numbers and the “K” alphabet in the LED bulb color temperature as the specifications. Those number and alphabet combinations are what we meant by Kelvin or CCT measurement.

When thinking about the Kelvin or CCT measurement in a light bulb product, we usually divide the definitions into three parts: 3000K, 4000K, and 5000K CCT light bulb products. Each of the measurements has different lumens, which contributes to their whiteness and brightness.

Normally, a product will have around 2700-3000K color temperature LED scales. Such ranges produce either yellowish or warm white-ish lightings that are similar to incandescent or halogen lamps, but with much more economical lighting usages. Some people see such gradations as similar to the colors of sunset and sunrise.

In DGT Lighting Co. Ltd, we maintain our lamp’s certified quality by only limiting our LED sales to reasonable amounts of Kelvin or CCT. Sometimes, the CCT that is too high can result in hurting the eyes. We will discuss this matter later on, along with the different CCT measurements in our light bulb collections.

How would you explain different CCT measurements?

Essentially, Kelvin and CCT reflect the same measurement to an adjustable color temperature LED system. The lowest score would be 0K. However, since 0K means complete darkness, there are no lights manufacturers in the world that sell such products.

So, we move forward to the 1000-1800K ranges. These products are what we refer to as equivalent to candlelights and matches. Since such ranges are not considered bright enough, we don’t sell them either. Even light products that fall somewhere around 2000-2500K ranges are rare to find in lighting manufacturers these days.

People need bedrooms to lay their heads on at night and wake up in the morning. These room spaces are where relaxation happens. Not stopping there, these things also make the LED 3000K color temperature products more common in lighting companies’ production plans, since bedrooms are so common in people’s lives.

Lighting manufacturers, suppliers, wholesalers, and the likes, usually sell products with around 3000-5000K CCTs. Most of them agree that such ranges of the LED bulb colors temperature are the most acceptable for humans’ eyes.

What does it mean by a 3000K lamp?

A LED 3000K color temperature falls under the warm white category. Hence, we see the output of such lamp products as having soft, yet warm vibes in the white areas. Such gradations motivate us to be still, quiet, calm, and relaxed in a room or a space.


So, we often recommend the 3000K product for people who are looking for the most compatible LED color temperature for home settings. In particular, we often install these types of lighting products in the bedrooms or the living rooms.

The bedrooms are the default places to get rest and feel sleepy. Even though we can’t do the same in the living rooms, living rooms with the 3000K color temperature LED products will have a cozy and comfortable feel for the guests. As a result, guests can have great in-depth conversations about the house with the 3000K lamps installed in accurate places and settings.

Even though not all 3000K lamps are the same, we can see the differences with other lamps, such as the 2700K, 4000K, or even 5000K LED lamp products. We will see the differences over the next sections.

Which one is better for me, the 2700K or the 3000K products?

The 2700K lightings are the closest match with the 3000K products when we see and compare the lights’ biases.

It is because the 2700K measurement resembles the first three hours in the morning and the first three hours right before the sun rises. On the other hand, the 3000K’s soft white hues resemble the next three hours after each 2700K resemblances.

The gradation and hue codes are even close to each other. Lighting industries all over the world recognize the 2700K lamps as having the “warm” hues like the conventional halogen lamps, while their 3000K counterparts have the classical soft and warm vibes to their whiteness.

In our opinion, both products have no better-LED color temperature for home spaces than the others. It all depends on the spaces you wish to install the products.

The 2700K lamps are ideal for dining room settings in many residential places and restaurants. Sometimes, we can apply lamp products with the same CCTs on outdoor balconies. Five or six 2700K lightings are common for the latter category, especially when the balconies have garlands and some vintage white decorations.  

How do we compare the 3000K, 4000K, and 5000K products?

The world’s lighting industries often map their LED bulb products using these three Kelvin(K)-CCT scales. According to our observations, those lighting industries can group their light products into individual scales and the others classify the products in ranging scales.

In general, the lumens rise 10% every 1000K increases. So, for example, a 5000K lighting bulb has 10% more lumens than a 4000K bulb or 20% more lumens than a 3000K product.

When we talk about the individual (stand-alone) scales, the 3000K products produce softer and warmer white tones. Sometimes, these lamps have subtle yellowish hues and gradations to their lights. As a result, these 3000K CCT products are ideal for rooms where relaxation happens, such as bedrooms or living rooms.

More specifically, bedrooms need around 2000-3000K CCTs when we talk about the Kelvin ranges for the lamp products. These color gradation ranges produce soft and calming hues of yellows that encourage our eye muscles to get a fantastic rest.

Moving forward, we have the 4000K CCT lamps. These lamps produce white hues that have bright, lively, welcoming, and natural vibes to their gradations. We often use the 4000K CCT products for kitchens, the spaces in our house that reflect our personalities and define the ways we have fun while serving our guest’s delicious foods and drinks.

The highest number in this LED color temperature chart comparison would be the 5000K bulb. These bulbs are the products that produce cool white colors like in the daylight. As a result, we can find these bulbs in study areas, security guards’ places, and various office environments.

Nonetheless, we don’t sell light bulbs with more than 5000K CCT (or CCT measurements that are too high) since these products tend to be damaging to the eyes. After all, many people consider 4000K bulbs bright enough to sustain their activities.

Can we consider 5000K bulb products as safe for our eyes?

Yes, 5000K is still safe for our eyes. However, we advise you not to go over 5000K for the LED bulbs color temperature or the LED color temperature.

One crucial thing you should remember when thinking of purchasing light bulbs and their entire equipment is that lumens don’t only stay as numbers. The more lumens a lighting product has, the more blue lights it will emit to the environment.

Many researchers have found that constant exposure to blue lights can cause damage to a person’s retinal parts. More precisely, those people will be 1.5 times more likely to suffer from breast cancers and two times more likely to suffer from prostate cancers. Some patients also suffer from macular degeneration due to the constant exposure to blue radiations.

Even though many lighting companies worldwide have started to discontinue fluorescent lamp production, we still consider fluorescent lights safer than the so-called “environmentally friendly” lighting products with a LED color temperature of 5000K and above.

More precisely, we will continue to produce the healthiest environmentally friendly lamp products, as long as our quality checks prove that their lumens and CCTs don’t exceed three times of the soon-to-be-abandoned fluorescent lights.

Some sources defend the need of having such intense light products for parking lots and other large-sized outdoor venues. However, here, in DGT Lighting, we never recommend our workers and customers to work under exposure of 5000K and above LED color temperature for a long time due to the health issues that they pose.

How can different color hues and gradations in lamp products affect humans’ brains and emotions?

The different ranges of LED lighting color temperature have many effects on the ways humans process their brains and emotions. One of the most evident things about this matter happens when we wake up in the morning and sleep at night.

Our brains receive signals about what we should do as soon as we turn on or off the lighting sources. Next, those signals are the triggers of the melatonin hormone in our body.

For example, our brains receive signals from the warm white color temperature of LED lights products. Even though it’s not yet the time to sleep, our increased melatonin production leads us to more relaxed states of mind. As a result, we find it more convenient to relax our mind and body in that particular place with warmer white light tones.

Conversely, the LED bulbs color temperature with bright daylight-typed hues and gradations triggers serotonin in our body. Serotonin is a hormone that contributes to a person’s productivity level. So, we tend to find those types of lamp products in spaces where activities happen, such as kitchens and many areas of retail stores.

At some points, LED lamp products with lighting hues that are similar to morning sunlights can improve body temperature conditions and increase heart rates during working times. Emotionally, such things always make us feel “on the go”.

Today, companies all over the world recognize the increasing requests for tuning the lights’ colored variations and controlling the color temperature of LED lights products.

Such requests become crucial since the color-tuning acts can improve the workers’ diligence and productivity as much as accurately regulating their at-work and at-rest moods. Some places that require color-tunings of their LED bulbs color temperature include retail stores, offices and warehouses, gyms, and healthcare facilities.

How do you control the temperature of your light bulb’s colors?

White color tuning, warm-dimming, and full-tuning are the three color-tuning techniques we recognize in our company.

The white color tuning part is the LED lighting colors temperature adjustment that most residential and office buildings use. We use this color adjustment system with our sophisticated lighting drivers that control the outputs’ white gradation parts.

We usually mix between warm and more neutral lighting products, which means the CCT ranges would be around 2700-3000K or so. For basic stores, we usually pack the diodes tightly together with some diffusers around the lights to adjust the biases’ angles accordingly.

We do the warm-dimming processes for clients who work in restaurants and other hospitality-related buildings. After all, this LED light color temperature adjustment system plays on the filament parts in ways that the after-effects become similar to incandescent dimming.

More specifically, the filaments will be closer to white as we make the lights operate in full output modes. The cooling down parts start when we dim the LED light products. The results are the alluring movements from white, yellow, to red – or, in other words, turning into warm gradations.

Full-tuning is something that we don’t usually do since this mixed adjustment is typically suitable for theatrical purposes. This is because full-tuning lets the lamp products switch between any lighting colors at random times within the selected time ranges, from the warmest to the coolest and vice versa.

What benefits can I get from adjusting the light CCT?

Many people are getting bored with LED light’s monotone solid hues despite their economical electric usage. As a result, such things as the LED light color temperature become the things that hinder their productivity.

Nonetheless, adding pleasure and excitement to the work progress (or aesthetic values to space) is not the only benefit we can get from having a LED product with adjustable lights.

Many people also proved that working under the correct light adjustments can improve productivity in many aspects. Those color adjustment scenarios can even fix our circadian rhythm that permits for good night’s sleep versus morning (and afternoon) activities balance.

The correct light’s colors will regulate your circadian rhythm

Circadian rhythm is another word for our biological (body) clock. Anything can add disturbances to our biological clock, thus triggering sleep disorders. The wrong LED light color temperature adjustments, settings, and more, are no exception to that “anything” part.


These days, we might remember elders advising us not to look at our electronic devices while sleeping. They are unknowingly referring to the lighting that the devices emit while we’re looking at them. All we know is that those “cool and bright blue” parts keep us awake at night while we should be sleeping at that time.


Conversely, we can wake up in the morning because our retinas and brains receive signals from the orange-yellowish hues of the morning sunlight.

Even so, the more we expose ourselves to the “cool and bright blue” electronic devices at night, the more we get up late because our brains have to balance the high CCTs with the (much) lower CCTs, which is unhealthy for our circadian rhythm.

We can improve our productivity

This number two benefit relates to the previous number one benefit about a person’s circadian rhythm. So, previously, we know that higher CCTs motivate us to stay alert and focused, while lower CCTs (that result in somewhere between orange, yellow, or reddish hues) make us more relaxed.

In work settings, the accurate placement, setting, or application of the CCTs will build up the moods of the workers. Many times, company clients who are working in schools, hospitals, retail stores, gyms, and the like, use our LED color temperature chart service in their different spaces.

We use the higher CCTs for co-working spaces and any rooms where workers execute detailed measurement works. Conversely, we use the lower CCTs for living rooms, banquet places, dining rooms, and the like to build up relaxing moods in those places.
