Have you ever noticed how certain lights make things look different? Take a hair salon, for example. The stylist dyes your hair and it looks great in the salon, but when you go outside, it’s a completely different color! That isn’t bad styling— but it might be caused by bad lighting. Here’s an in-depth review of the Color Rendering Index and how it might affect your business.

Visible Color and Light Color: The Basics

You may remember this from school-age science classes, but what we perceive as white light is actually all the visible colors of light mixed together. Natural light sources, like the sun, produce all these colors, as shown through any prism, while artificial light sources often emit only a few colors. The color we perceive in objects depends on the colors absorbed and reflected by the object, so objects unable to absorb the usual spectrum of light will appear a different color than usual.

Keeping Track of Color: The Color Rendering Index

The Color Rendering Index is a measurement of light’s effect on colors. It measures how many of the usual colors emitted by white light are emitted by a given light source. Light sources that are very similar to full-spectrum natural light have a high CRI rating, up to 100. Lights that lack certain colors and aren’t full-spectrum have a low CRI rating, somewhere below 70.

How CRI Affects Business

Having high CRI lights in your place of business can be extremely important, especially when perception and image is at stake. Businesses such as hair or nail salons, art galleries, car dealerships, and photography studios must be especially careful to install high CRI lights. If a customer invests in a product, hair color, car, or anything else color-dependent, only to find out that it isn’t what they originally saw… That unhappy customer poses a risk to your reputation and future business. 

Low CRI lights aren’t defective or universally undesirable, but they do have specific uses. You may see low CRI lights in street lamps, light posts, or stadium lights.

Another Note: Color Rendering Index vs Kelvin Scale

Because color and light have a huge impact on our perceptions and opinions, CRI isn’t the only way to rank a light’s quality. While the CRI measures how a light affects an object’s color, the Kelvin scale measures the color of the light itself, providing the correlated color temperature (CCT) of the light source. Oftentimes CCT and CRI get confused with one another, but they’re just different measurements of light quality that are relevant to different situations.

Don’t Stress- Just Check the Package

Now that we’ve learned what CRI and CCT are, let’s imagine you’re picking out a lightbulb. Each package should tell you the CRI and CCT ratings for the bulb, and you may see some common trends. Typically, high CRI lights are also fairly high in CCT. For example, a light bulb that emits light at 2700K (warm light) usually has a lower CRI (less true color) than that of a 4000K light bulb (blueish light) with a higher CRI (truer object color). This is not always the case, but it is common.

If you have doubts about selecting the right bulbs for your business, or any other questions, our lighting experts at Super Lite are here to help. Reach out to us and we’ll make sure your business puts its best foot, and best color-quality lighting, forward!

Thanks to old age and plenty of other conditions, bad eyesight is far too common. Some of us here at Super Lite suffer from it, too! Surprisingly, home lighting has significant influence in improving (or worsening) one’s vision. So though your home lighting likely has great style, it may not be functional for struggling eyes.

Luckily, there are plenty of ways to light for function and style. In fact, having the right home lighting can make details clearer and reduce the need for magnification. Improving home and office lighting can simplify everyday tasks and ease vision strain, so try applying a few of these easy tips! 

1. Use Natural Light Whenever Possible

The first suggestion is to be in natural light at every possible opportunity. Sunlight provides a soothing, bright light that maximizes vision and improves mood. For flexible activities like crossword puzzles, reading, or even homework, place a chair in natural lighting and enjoy the benefits of the brightness.

2. Switch to LED Bulbs

Aside from sunlight, the next best lighting option is LED bulbs. They provide bright light, last for hours, and come in a variety of cooler tones than incandescents. LED lights last thousands of hours so you won’t need to worry about replacing them after they’re purchased.

3. Increase the Number of Lights

Another simple way to boost your lighting is to increase the quantity of lights in the home. Lamps are a great way to start, since they require no structural changes. Remember, when putting lamps in a room, maintain consistent light throughout the space to avoid having dark spots. Also note that lamps with exposed bulbs will increase the glare, so avoid those when possible.

4. Use Lamp and Lighting Timers

Prevent any stumbling around in the dark by putting your lamps and task lighting on a timer. These automatic timers can turn on lights in the times they’re needed the most, lighting key areas. They prevent extra difficulties because without unexpected dark hallways or rooms, the eyes don’t have to adjust from lit rooms to dark spaces.

5. Maximize Task Lighting

Consider your frequent tasks. We’ve been around lighting long enough to know that there’s always some type of lighting that can make those tasks easier! There are adjustable lamps that illuminate your specific task, like a gooseneck lamp. Hanging fixtures can also be pointed at desks, chairs, or other areas. You might even need less magnification because of the better illumination!

Keep in mind, these tips may not work for every eye condition, but they’ve helped us! You can always contact us, or a vision specialist, to determine what type of lighting will be most beneficial for your unique circumstances. 

Are you tired of the bedtime battle? You know, the daily conflict that occurs between you and your children to get them to sleep? Perhaps your child is anti-bedtime and creates a skirmish to get to the bedroom, but then deals ok with it. Or, maybe your child is the type to leave their bed several times to tell you they can’t sleep, before wearing themselves out and finally catching zzz’s a few hours later? No matter what you and your child’s bedtime struggle looks like, there are some scientific studies that show why bedtime can be difficult for kids. While you may not realize it, one primary factor is melatonin production, which can be thrown off by the type and tone of lighting in the home. Specifically, the light around and in the child’s bedroom, and how much blue light (emanating from technology), is taken in just before bedtime. Blue light can be found in high amounts from technology screens as well as ordinary light bulbs of lower quality. 

One of the biggest factors affecting a child’s bedtime routine? Light.

Studies show that the more blue light a child is susceptible to, the harder the body has to work to produce melatonin, the hormone that regulates sleep. According to a New York Times article, the general consensus is that “Children’s eyes let in more light than adults’ eyes do.” If the blue light radiating off of our technological devices affects adults so much, that only means that children are that much more affected the same light. So, those bedtime videos, games and stories that may come from a phone, tablet, or TV, all are stunting melatonin production in the child, resulting in a more difficult bedtime transition. 

In the study that the NY Times cited, it showed that the average beginning of the child’s biological night (when melatonin secretion began) was approximately 7:47 P.M  with the average bedtime being about 8:27 P.M. This scenario occurred when the children were exposed to a living situation of being in a dim-lit “cave” of sorts, where no bright light interfered with the beginning of their biological night. However, they alternatively studied how light exposure suppressed melatonin production and found that the rate suppressed production by 90%, with the effects lingering long after the children retired into a dim-lit space. 

What does that mean? It means that blue light exposure before bedtime should be restricted, and that will result in a more seamless transition from day to night. Nowadays, you can go into your phone settings and set “night mode”, which will change the screen light from a harsh blue to a warm yellow at a time that you choose. If technology is a big part of your bedtime routine, this solution may behoove you,  but you might find it more beneficial to eliminate all exposure to blue light within an hour of bedtime.

Turning the Sleep Space into a Dark Cave

So, you’re interested in the idea of a “dark cave” to help with the bedtime battle, but you don’t want to rewire or renovate in an expensive way. We’re here to tell you that this doesn’t have to be a big budget blow. After researching the best color light for sleep, results show that warm LED lights take the cake. If you think about it (and think about the color wheel) warm tones (red, orange, yellow) are the direct opposite of cooler colors (green, blue, purple) so naturally, you’d think warm light would act inversely to cool light. The authors of a Life Hack article suggest that in the evening, a switch should be made from bright, abrasive overhead lights in favor of table lamps, or smaller sconces would held  to maintain a proper circadian rhythm. Typically, these smaller light sources are accompanied by warmer bulbs (under 3000k), which is the crux of the matter. Warm light more closely mimics the setting sun and is gentler on the eyes (and better for the melatonin production) and encourages a smooth transition from being awake to falling asleep. Keeping these warmer, eye level light sources on around the home after sunset can yield a simpler, smoother transition, especially for children, from day to night. 

A supplementary behavior that will take time to adjust would be down a similar vein to restricting blue-light technology would be to adjust the amount of direct light on the child’s eyes. Illuminated technology (e-readers, tablets, phones, televisions, computers) could and should be used indirectly in relation to a child at nighttime (say, the parent reads off of the tablet while the child lays tucked in, or audio is played without video). This reduces the direct blue light shining into the eyes of a child, and will, therefore, reduce the suffocation of melatonin production.  Using book lights or table lamps to light an activity (say, reading an old-fashioned bedtime story) indirectly lights the source of activity, so there is less strain on the child’s eyes. To reiterate, the best color light to promote sleep is any variant of warm light, perhaps yellow or amber light. 

A third option would be installing dimmer switches around the house so that you can control when the lights go from high to low. If you have these switches around the house, you can ensure that even the overhead lights go from bold and bright to soft and low consistently across your house. It saves the necessity to purchase additional table lamps or installing hallway sconces if you’d rather have a holistic household solution. 

Quick Tips for Lighting a House to Promote Sleep

So, maybe your child is afraid of the dark. We all know we had our bouts of fear for monsters in the bed or in the closet, waiting for the parents to slink away and for the lights to go off. There’s no discounting a child’s fear here. Instead, we propose simple solutions to combat that with night lights. The quick tip here is to ensure that bedtime lights are kept low in location and low in brightness. If they’re out of the direct line of sight of the child, they won’t harm the melatonin production and general sleep cycle of the child, and the light provides that safety blanket from the scaries lurking in the dark. Keep in mind what we’ve explored about light temperature, and seek out night lights that contain (or can be mounted with) warmer light bulbs rather than cool bulbs (many can be found marked as low blue light bulbs).

The fact of the matter is that light affects sleep and that children’s eyes are more susceptible to light, which makes their nighttime transition bumpier. Luckily, light is something you can control, for the most part. You can buy blackout shades, change out light bulbs, opt for the best color light to promote sleep, enhance melatonin production with warm LED lights, and set an off-time for electronics. Whatever you choose to do, Super Lite can help you control your homes’ light. Making small changes like the ones mentioned earlier can be the first step toward putting your kids to bed (and getting them to fall asleep) with no hiccups.
