Do find yourself experiencing tension headaches and eye strain while working at your desk?
Are your eyes tired after going over your household paperwork?
Better lighting can help.
Your workspace may not have the light you need to optimize your productivity, reduce eye strain and tension headaches.
Several factors contribute to your overall light experience, color temperature, brightness, and intensity. Lighting solutions can include more light, adjusted color temperature lighting and focused lighting on your task at hand.
Many offices are still in the dark, using harsh fluorescent lighting in office spaces which can result in mood changes and decreased productivity. Often we need more light than what we are using in our work spaces. When we aren’t getting the light we need, then it can be more difficult to stay focused without tension. Light that is more naturally attuned towards the colors of the sun can be easier on your eyes…allowing you to work for longer, with less eye strain.
Color temperature is important, and having options to adjust color temperature enable you to fully customize your workspace to suit your lighting needs. This allows you to find your desired warm or cool color temperature to help your eyes see easier.
Your light needs to be where your eyes are focused or it won’t be as effective. Light directed on your work seems like an obvious solution; and yet, how many people are working without desktop lighting and instead relying on the indirect ceiling lights for office light? Directly focused light on your paperwork will make a difference you can see!

Did you know that there are some easy ways you can save a few bucks and reduce your carbon footprint? Making your home more energy efficient is good for your pocketbook and your peace of mind. Here are five simple ways to do just that:
1) Plant a tree. Planting a shade tree on the side of your house that gets the most sunlight can greatly reduce energy costs. As the tree grows, it will provide shade over your home during the hottest months, reducing your air conditioning bill. Choose a beautiful shade tree you can enjoy now and thirty years from now, and reap big dividends later.
2) Set up a rain barrel. Have you ever considered how much time and energy it takes to deliver clean water to your home? It’s substantial! Buy a couple of rain barrels and use the water to irrigate your garden. Save energy and water and reduce your water bill.
3) Get the right light. Replacing your fluorescent bulbs with LED bulbs is a small investment to make now that can result in savings later. Also, consider swapping out those less energy-efficient floor and table lamps with an energy efficient Microsun Lamp, which provides up to eight times the amount of light as a regular lamp bulb while using less energy.
4) Insulate water heaters and pipes. While we are quick to insulate the walls of our homes, many forget that a substantial amount of heat can be lost through our water heaters and pipes. Cover your water heater with an insulated blanket and have foam or rubber pipe insulation installed to reduce heat loss from hot water pipes.
5) Upgrade your thermostat. Older thermostats require one to flip between activating the furnace and the air conditioner to provide the optimum temperature. Newer “smart” thermostats can be programmed to keep your home at the ideal temperature throughout the day.
Spectral power distribution is a visual representation of color outputs from a light source.
According to the Illuminating Engineering Society, SPD curves can be used to compare the color composition in different light sources. Each type of light has its own color properties, which are based upon the wavelengths present in an illumination source. Although the human eye sees a certain color, light is actually created from blending various hues of the visible spectrum together.
An SPD curve has all of the colors of the visible spectrum laid out on a graph. Wavelengths are noted on the x-axis in nanometers and relative power is on the y-axis. Light with the shortest wavelength is blue and light with the longest wavelength is red.
SPD curves vary across light sources, as they all have subjective properties. Natural daylight has even distribution of power across all wavelengths. Tungsten incandescent lighting has significantly more red light than blue light. Most of the power in high-pressure sodium lamps goes to yellow, green and orange light.
Fluorescent lighting is low on red, but spikes with yellow, green and blue light. Ceramic metal halide lighting has the highest power output from yellow, orange and green light as well as fair amounts of red and blue light.
These measurements are not static, as each individual lighting product has different specifications.
Wavelength and the visible spectrum
Light travels in the form of waves.
For the sake of a visual representation, imagine large ocean waves crashing on a shore. Each other those waves has a crest and a trough. Crests are the highest point from a rest position a wave can achieve and troughs are the lowest point a wave can achieve from a rest position. Wavelength is the distance between two crests.
NASA states that wavelength is equal to the speed of the wave divided by the frequency. This equation is why red light and blue light have different wavelengths. Each color travels at a different speed, even though the difference may not be noticeable to the naked eye.
Light, known as the visible spectrum, consists of all of the waves the human eye can see. It is a small part of the entire electromagnetic spectrum comprising x-rays, microwaves, infrared waves, radio waves, long radio waves, ultraviolet rays and gamma rays. The human eye can see light with wavelengths from about about 380 to 760 nanometers. A SPD curve shows how much of each of the visible waves is emitted from a light source.
Describing color for electric lighting
Color for electric lighting does not blend in the same way our preschool teachers taught us to mix paint.
The primary colors for light are red, green and blue. For some, this combination seems odd, as we traditionally learn that primary colors are red, blue and yellow. Light works a little differently.
Yellow light, for instance, is not yellow. It is actually a combination of a a lot of green and red light and very little blue light. Black is the complete absence of light, and white light is a combination of large amounts of red, blue and green light.
In most residential and commercial uses, colored light is not necessary as white light is the norm with varying color temperatures.
Deciphering spectral power
A special tool is used to measure spectral energy.
These tools are called spectroradiometers, according to the IES. They determine radiometric, photometric and colorimetric qualities of a light source and most often use prisms or diffraction gratings to disperse the light.
The measurements are converted into a SPD graph, which includes UV and IR wavelengths as well as very small band pass increments less than 1 nanometer.
Spectroradiometers are not commonly owned devices because they are expensive and not easy to transport. However, consumers can request a SPD curve for any lighting option they are considering.
Using spectral power distribution in lighting decisions
Now that we have an established understanding of the science of light, how is it going to help purchase the best lighting products? Each kind of light source has different effects on vision and mood due to the wavelengths they give off. Checking out an SPD graph is simply another way to ensure that the colors emitted by a light source will not have any negative implications for sight or emotion.
According to a report from the city of Southampton, N.Y., blue-rich white light is in high demand. High intensity discharge lamps, such as metal halide and high pressure sodium bulbs, emit more energy at the middle of the spectrum. LEDs with higher color temperatures give off cooler white light and emit more energy from the blue end of the spectrum.
Choosing between those options comes down to the application. Eyes that have adapted to darkness are more sensitive to blue light, which means that blue-rich white light will seem brighter than warmer light. Based upon this factor, outdoor lighting sources would need to emit more blue energy than red energy for the most brightness.
Blue-rich white light is also beneficial as people age. The eye lens begins to yellow more as people get older, which causes more blue light to be absorbed. As the lens absorbs more, less light gets to the retina. Blue-rich white light sources help slow this change by providing enough light and contrast.
An SPD curve can also show whether or not glare caused by a light source will be discomforting.
Light with a wavelength of about 420 nanometers has the greatest potential to create discomfort glare, according to the Southampton report. For older people, any light source with high spectral output below 500 nanometers will have a lot of glare.
Examining an SPD curve is an easy way to figure out what light source works best for a certain space. Even if people do not understand all the science that goes into the measurement, they should be aware that such a resource exists to give them more insights into making a lighting decision.
While the amount of light you have in a room is mostly due to personal preference, there are some recommended brightness levels for different rooms.
Having optimal brightness is not solely for visual purposes. It is integral for preventing eye strain and ensuring your light conditions accommodate your visual needs. Determining the brightness required for a room is not as easy as plugging in floor reading lamps until you’re satisfied. With a simple calculation and slight adjustments, you can get the perfect amount of illumination.
Talking about brightness
Like other light quality metrics, such as correlated color temperature and color rendering, brightness has its own unit of measurement. In the U.S., the light emitted from your bedside reading lamps, pendant fixtures or any other source is often denoted using foot candles. This unit tells you how bright a light is one foot from the bulb. In recent years, however, lighting industry experts are more often using the measurement known as lumens for consumer-facing materials. Although lumens and foot candles may seem similar, they are actually different.
Given that you’re more likely see the number of lumens on bulb packaging, let’s focus on that measurement. Keep in mind, however, that foot candles are important for determining how many lumens you need in a room, as one foot candle equals one lumen per square foot.
Break out the tape measure
The brightness you need in a room varies both by the tasks completed there and the size of the room. Yet, knowing the latter can give you a good idea of how many lumens you need prior to considering how the space is utilized. For instance, you likely spend more time reading in your office than your in kitchen, which means there should be more light where you work.
Start by figuring out the square footage of each of your rooms. Use a tape measure to note the length and width and be sure to account for irregularly shaped rooms. Once you have the measurements, you can calculate the lumens needed to completely illuminate the room.
Grab a calculator
With a few reference measurements for foot candle needs for different rooms, you can use your room measurements to calculate the lumens required.
Bathrooms and above kitchen stoves and sinks (70 to 80 foot candles)
General kitchen lighting and dining rooms (30 to 40)
Bedrooms and living rooms (10 to 20)
Hallways (5 to 10)
Next, multiply the square footage of the room by the foot candles required and you’ll have the lumens necessary to adequately light the room. Don’t forget that your calculations may not provide optimal brightness, as room configurations, furniture and other factors can affect the ambient light levels in your rooms.
A note about equivalencies
As more incandescent bulbs are phased out of production, you may also see more lighting product packaging have information about brightness equivalencies, particularly on more energy efficient products like compact fluorescent and LED bulbs. Usually, this information references lumens per watt, which tells you how much brightness you get for each unit of energy. Although this may seem like an additional bit of confusing information, equivalency data simply tells you how much energy you save while getting the same brightness.
If, for example, you were considering a 13-watt CFL bulb that was said to be equivalent to a 75-watt incandescent bulb with 1150 lumens, you’ll be getting the same number of lumens while using 62 fewer watts. There are, however, always chances of inflated manufacturer claims about equivalencies, so be sure to research products to ensure you’re getting what you pay for.
Don’t forget the personal factor
Whenever selecting bulbs, keep in mind that these are general guidelines for finding the best light for your home. If you have aged-related vision problems, such as cataracts or macular degeneration, or if you simply have trouble reading, you’ll likely need more light that the average consumer. These conditions are known to require brighter light and may present additional considerations.
Patented Lighting Technology to Enhance your Home’s Environment
It should be obvious by now that a middle age adult needs three times MORE LIGHT than a teenager. But our homes seem dimmer than ever!
This is because we are trying to save energy with an ever more CONFUSING array of screw in devices and bulbs (mainly CFL and LED). However, the end result of these “retrofits” is a substantially LOWER level of light than we had before!
Why we need MORE LIGHT and BETTER LIGHT QUALITY:
The eye’s crystalline lens yellows with age. As we grow older, we need more more blue green spectral energy to compensate for this effect.
The eye’s pupil size gets smaller as it ages so we need MORE LIGHT, but we want LESS GLARE.
Over time, the eye will suffer a loss of transparency in the pupil AND the lens.
Our Microsun lamps guarantee you more light and higher light quality.
