If you have read our page about the meaning of color temperatureyou understand that the Kelvin rating on a light bulb or fixture indicates the shade of white light that emits from that source. Just as sunlight transitions from orange shades in the morning and evening to blues during the middle of the day, artificial lights also emit a specific color temperature.
Each color temperature has an application that is appropriate for it, and good lighting design incorporates that into an overall plan of how to light an office building, a manufacturing facility, or a residential home.
Knowing your environment and context are critical to choosing the right color temperature, and can make all the difference in things such as employee performance or the consistency of your sleep cycles. Throughout ShineRetrofits.

Save on our wide assortment of energy-efficient LED bulbs, available in a variety of shapes and sizes. LEDs deliver quality light across a broad spectrum of color temperatures from warm ambient light to the bright white look of daylight, to suit any indoor or oudoor application.
The brightness of LEDs, however, is determined a little differently. Instead, a different form of measurement should be used: lumens. The lumen lm is the real measurement of brightness provided by a light bulb, and is the number you should look for when shopping for LEDs.
LED lighting offers a range of color tones perfect for any application, from the soft look of an incandescent bulb to the bright white look of daylight. LEDs produce a wide range of color temperatures from Kelvin warmer light to Kelvin and above cool white.
Most dimmers, which were likely designed to work with incandescent bulbs, work by cutting off the amount of electricity sent to the bulbs. The less electricity drawn, the dimmer the light. Since there is no direct correlation between LED brightness and energy drawn, you need to ensure your LED on a dimmer switch can result in some LEDs to hum, flicker, or buzz. If you want your LED bulb to be dimmable, you need to do one of two things: find LED bulbs compatible with traditional dimmers, or replace your current dimming switch with a leading-edge LED-compatible dimmer.
LEDs can be used in enclosed, semi-closed or open fixtures, but you need to make sure you buy the right LED for your application. LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb.
From there, the heat dissipates into the air, keeping the LED bulb cool, which helps to keep its promise of a very long life. And therein lies the problem: the bulb needs a way to dissipate the heat.
If you have fully or semi- enclosed fixtures, you need to make sure the LEDs are approved for recessed or enclosed spaces to avert any preformance issues. Shop LEDs for recessed or enclosed spaces. Looking to switch to LED lighting? Let Bulbs. LED light bulbs, or light emitting diodes, are low heat, long lasting, energy efficient lighting alternatives for your home or business. Whether you were drawn in by the long life of LED bulbs, their advanced energy efficiency standards, or their durable nature, there is likely a LED bulb to suit your needs.

And in short, the higher the Kelvin rating expressed in Kthe whiter the light will be. Color temperatures higher than K are typically used for commercial and hospital applications, as the light is bright and has a bluish daylight cast that can be harsh for home interiors; but task lighting may be useful at K and above.
The right color temperature begins with the bulb. Whether you need an ambient source of light or one for highly-focused task lighting, keep in mind the following Kelvin ranges:. While supplies last. Your gift will appear in your cart. One gift per customer, while supplies last.

Bathroom Bathroom Lighting Bathroom Furnishings.Many first time grow light users or those who want to start to dabble into growing their plants under artificial lighting at first are very confused about all the different color temperatures or color spectrums of T5 grow light bulbs, so here is a little guide to help you understand them and to use your lights better and to their full potential.
First off I should explain a bit more about the terms that will be used in this article and that need to be known for you to fully understand grow lights. Color spectrum or the visible spectrum is the light that we can see with our eyes, we can differ various colors or hues of the light, but when it comes to be precise then better to stick with the color temperature measurement to ensure that your plants get the light they need in the specific stage of their growth.
The most common bulbs sold are ones with the color temperature of 6, Kelvins, because usually these types of bulbs come with T5 fixtures and have the biggest selection among different manufacturers. Sometimes there are 6, Kelvin or even 6, Kelvin bulbs that are essentially the same thing, because all these bulbs will emit light that is similar to the light that we see during daylight hours, it is called a daylight white light and it has blue tinge to it.
In fact any bulbs that have the color temperature of 5, Kelvins and up will emit daylight white light, it only will slightly differ how cool or blue the light will be. This type of light is best and most useful for plants that are growing or in their vegetative stages of their growthbecause the light is similar to light that they would get if they would grow outside during daylight hours.
Also this light is good for seedling and cloning of the plants because of the same daylight reason. The other most common color temperature in T5 bulbs is 3, Kelvins. To the human eye they can seem as they have light blue tinge to them though.
Because the light is neutral, not leaning in favor of red or blue spectrum, it can be described as standard and therefore can promote plant leaf as well as stem growthbut can be also used when the plants are flowering. And you can also find T5 bulbs with the color temperature of 10, Kelvins.
Most commonly they are used as aquarium lights. The 10, Kelvin color temperature means that they are very blue based lights so they can be used as grow lights for extreme plant growth, because of the cool color of them. But they usually are used for marine aquariums that have reefs and fresh water type of marine life in them, because the color spectrum also is quite similar to the light that could be seen in deep waters or ocean.
So for all those who own fresh water aquariums or simply want to experiment with plant growth these bulbs are for you.

Blogger, editor and owner of t5fixtures. Interested in gardening related stuff, especially grow lights. Hi Anil, Thank you! And yes, you can combine them as long as both T8 lights have the same wattage. Regards, Ben. What are lights that are rated ? Are they just a mix of and ? And what would have the bigger effect on yields, a plant grown in a that produces a smaller plant, or a plant grown in something like a that becomes taller because of it?
Meaning that they are warm white bulbs, whiter in color than 3, Kelvin bulbs, but more yellow in color than 4, Kelvin bulbs. As for which will have a bigger effect on your yield, it depends on what plants you are growing, because there are plants that respond better to yellow bulbs and ones that like while light better. So you need to do your research. A general rule of thumb, though, is that growers use 6, to 6, Kelvin bulbs when their plants are growing in the vegetative stages of plant growthand 3, to 3, Kelvin bulbs once their plants start blooming in the flowering stages of plant growth.
And this formula usually provides the best results. Such a useful article.Color temperature is measured in degrees Kelvin K. The color temperature of a lamp bulb describes how the light appears when the human eye looks directly at the illuminated bulb. Color temperature is measured by a unit called the Kelvin K.
The Kelvin thermodynamic temperature scale is defined so that absolute zero is 0 kelvins K. Imagine heating a bar of steel and observing the color of the bar at increasing temperatures. At some point the bar will appear to glow a dull red.
As heat is added, the dull red turns to yellow, then to white, then to bluish white, finally to blue. A light bulb that produces light perceived as yellowish white will have a color temperature of around K.
As the color temperature increases to K - K, the color of the light appears less yellow and more white. When the color temperature is K or higher the light produced appears bluish white. The color temperature of daylight varies, but is often in the K to K range. When the desired lighting effect is "warm", use light sources in the K - K range.
Most common incandescent light bulbs will produce light in this color temperature range. An exception is the incandescent light bulb with a neodymium coating. The neodymium filters out the yellow and red wavelengths of the visible spectrum leaving predominately blue wavelengths. So even though neodymium light bulbs have a K color temperature, the light they produce appears to be bluer - similar to daylight and to other light bulbs that product light with color temperatures in the K or higher range.
When the desired effect is neutral or bright white, use light sources in the K - K range. For a slightly bluer, "cooler" effect use K. Daylight color temperature at noon is K, but sunlight color temperature can vary widely based on time of day and weather conditions. To give the perception of daylight bluish white lightuse light sources with a color temperature of K or higher. When deciding on the best light bulb for a particular application, one consideration not to overlook is the appearance of the light as perceived by the people using the space.
For example, many people will find a formal dining room more appealing with "warmer" appearing light, while for a large, open-plan office "neutral to cool white" appearing light is the better choice. Color temperature designations of light bulbs can be confusing. Sometimes you'll see subjective terms such as "warm white" or "cool white. Here are some approximate reference points: candle light is K warm yellowa standard 60W incandescent light bulb is K warm whitelights in a portrait photo studio are K neutral whitefluorescent lights in a classroom or office are often K cool whitedaylight with a thin overcast sky is K bluish, white light.
Most incandescent and halogen bulbs are in the Kelvin range KK. Fluorescent, metal halide and LED bulbs can be purchased with color temperature options from K to K.
It is important to note that color temperature is not the same as color rendering. The color temperature of a light source does not describe or predict the ability of that light source to render color accurately.With modern lighting technologies, home owners can choose not only the brightness of their lights, but the color temperature.
Measured in degrees Kelvin Klower temperatures tend to produce a warmer amber light, while higher temperatures produce a cooler, whiter light. The primary Kelvin range used in residential outdoor lighting is between kk. As a rule of thumb, warmer color temperatures are used on architectural elements between kk and slightly cooler temperatures are used on plant material in a landscape generally kk.
Many plant specimens appear more natural when illuminated by a higher kelvin light source.
Using the right types of lights for various outdoor lighting applications is an important consideration. There are no hard and fast rules, so depending on the mood or effect you are trying to create, you may require different types of lighting for different parts of your landscape. The best color temperature for your outdoor lighting is really a matter of choice. And the best choice is the one that creates the effect you want.
Stay away from cooler color temperatures when lighting outdoor landscapes. The bluish tones from cooler temperatures can make environments appear sickly or unnatural, imparting a sense of uneasiness, and being on edge. Instead, opt for lighting with a very warm color temperature: K LED is ideal, and K is okay, too.
The K temperature offers a very soothing and natural tone that mimics the warm, comforting glow of a campfire. As such, it is ideal for creating relaxing, comfortable outdoor environments. When you are lighting entertainment areasconsider lights on the lower end of the Kelvin scale, around K, providing a warm reddish glow that can mimic the light of a flame.
This is the same light you get from candles, tiki torches or a glowing bonfire. Strategically placed, lights in this range are all you need for a romantic or rustic feel. Consider K artificial moonlight lights placed high in trees and aimed down to provide a broad light that washes over the area below. These lighting fixtures come equipped with special glare shields that wrap around the bulb to ensure light goes downward. For all of your outdoor and landscape lighting, select a soft white light that is gentle and relaxing to the eye.
Use with wash lighting over the facade of your home. Warm White K. Similar to halogen-type landscape lighting, it is the most preferred color temperature for landscape lighting. Psychologically, it is thought to be more welcoming and soothing compared to higher color temperatures. Warm or Natural White K. Noticeably cooler than K, some landscape lighting pros prefer this temperature.
It tends to accentuate greens and blues in vegetation. Cool White K. Quite bluish compared to K, this is sometimes used to illuminate blue vegetation such as blue spruce. What Is Color Temperature?

Photosynthesis is the process through which plants turn water and carbon dioxide into their food sugar in the presence of sunlight.
Plants take in carbon dioxide from the air through openings in the leaves and convert it to sugar during photosynthesis. Chlorophyll is the green pigment in plants that makes it possible for them to create their own food, and it also gives plants their green color.
Water is necessary for plants to undergo photosynthesis, and plants absorb it through their roots. Oxygen is released back into the atmosphere as a by-product of photosynthesis. The light duration, or the amount of time the plant is exposed to the sunlight, is important as well.
The duration of light changes with the seasons. This affects the temperature of the environment as well. Summer has the longest duration of sunlight, followed by spring and fall, and winter has the shortest duration of sunlight. Not all plants need the same amount of light. Plants that produce fruit, such as tomatoes, tend to need more sunlight than those that do not. For example, strawberries need more sunlight than lettuce to grow.
Fruiting plants grow best in summer, and may need up to 18 hours of light per day to flower and produce fruit. On the other hand, some plants, such as cauliflower and cabbage, grow well in late fall and need as little as 12 hours of light per day. The electromagnetic spectrum is the range of wavelengths or frequencies over which electromagnetic radiation extends.

The electromagnetic spectrum consists of both the visible spectrum, the type of light we can see, and the infrared spectrum, the type that we cannot see. The four seasons have different durations of light, which can affect photosynthesis. There are certain colors of light that are more important for photosynthesis than others. Plants are adapted to absorb and utilize the proper amount of light in order to grow naturally outdoors.
When growing plants indoors, we must recreate the light produced by the sun, keeping two important factors in mind: color temperature and duration. The temperatures of the colors on the electromagnetic spectrum are measured in Kelvin.
