CCT indicates the hue and tone of white light emitted from a specific bulb or fixture. It’s measured in Kelvins (K), which is similar to degrees in Celsius. Different temperatures on the Kelvin scale represent different colors. For example, light at 2000K-3500K looks more orange/yellow and is called ultra warm or warm white, and as temperature increases in Kelvins, color changes to more of a “paper white” known as natural or neutral white (between 3500K and 5100K) and finally into a bluish-white known as cool white (5100K+).

As a light source’s color temperature increases, brightness often increases. While shopping for LED lights, pay close attention to the color temperatures that are available for any one bulb or fixture. Choosing a warm white bulb with a color temperature around 3000K might mean sacrificing some brightness. Whereas, if you choose the natural white version, it’s likely that it will have a higher output.

In order to understand nanometers, you must first understand the electromagnetic spectrum and wavelengths. The electromagnetic spectrum is the entire range of invisible and visible light, and a wavelength is the distance between peaks of light waves. Wavelengths are measured in nanometers, which are simply units of length that indicate colors of light within the spectrum. Nanometers will tell you how red, green, yellow, purple, etc. a light source really is. These measurements start lower at ultraviolet and increase from green to blue, yellow, orange, and then red. The wavelength of a colored light can be found in the light’s specifications table.

Fixtures or bulbs that emit wide beams, such as BR LED bulbs for can lights are great for areas that require a lot of light, such as basements, kitchens, or living rooms. Narrow beam angles like those from can lights with MR LED bulbs are best for highlighting decor or small areas. Globe bulbs, such as G30 LED vanity bulbs, have 360-degree beam angles, which means that they throw light in all directions. Globe bulbs are the perfect choice for centralized light fixtures.

There are many handymen all over the world, and while we salute them, we have to remind everyone that there are licensed professionals in place for a reason. Your brother-in-law might be able to get the quick odds and ends completed, but if the job is not being done right or a larger problem surfaces, take care of it correctly or you could be paying more than you expected to save.

Licensed electricians are licensed because they have gone through the training and testing necessary to do the job safely and correctly. After years of training on the job and in the classroom, licensed electricians are required to complete an exam that tests their full understating. This process allows electricians to enter the field with the right knowledge and experience under their belts.

As a licensed electrician, we can obtain permits on your behalf. Some work requires you to apply for a permit from the city. If you do work that is not permitted you can be slapped with a fine you didn’t budget for. An Expert Electrician will help to identify the required permits and avoid costly fines.

Part of all the training that licensed electricians go through is to sharpen their sense of safety and make them aware of any dangers on site. When our electricians begin their work they will identify any hazards that could harm the home and its occupants. This means when a job is done, all safety issues will be addressed and you can have peace of mind about the work completed.

When you hire a licensed electrician you can be sure they understand all the safety codes and building codes. Any work performed will be done up to code so it does not need to be redone in the future.

So while we respect all those handy people out there that like to get the job done themselves, we want to encourage you to use the experts when the occasion calls for it. Don’t let your home end up on a disaster DIY show.

Electrical troubleshooting in Fairfax, VA can help fix those electrical problems that, while perhaps not perceptibly major, can seriously hinder the performance of your home’s electrical fixtures. We’ve all had that one electrical problem in our homes that never seems to go away, leaving us in a state of constant frustration. At the worst, these problems can impact how we function in our homes on a daily basis, and even pose a threat to our safety.

Here in the MD/DC/VA area, it’s not uncommon for us to lose power when a summer storm rips through. And while these outages sometimes last only a few hours, storms that have occurred over the past several summers have left people in the dark for several days at a time. At Kolb Electric, we’re big fans of Generac generators—they are among the most reliable systems available, and they’re the only ones we install. That said, there are a few things you should consider if you’re thinking about installing a standby generator:

You can’t stretch the amount of power that generators supply, so make sure you receive an NEC (National Electric Code) approved load calculation with each proposal. Kolb Electric will provide this calculation with our estimate.

Standby generators must be permitted prior to installation and inspected following installation. Kolb Electric will do the work of acquiring the necessary permits for you, and we want to remind everyone not to have your system installed by a contractor who says they can do it with no permit. HOA requirements and approval processes vary, but key concerns often come down to noise and location.

In the event that your standby generator installation does not require a permit, make sure to ask if it will be installed up to NEC code.

Some people install generators to keep the essential functions of their home running, such as the refrigerator and a few lights. Others install theirs to be able to carry on with life as if nothing had happened. Before you install a standby generator, decide what you’ll want to run and what you can do without. Remember—too much capacity will needlessly inflate the cost of your system, so try to be realistic when deciding.

At Kolb Electric, we’re committed to installing your generator efficiently and effectively. Even so, the generator installation process can get hung up at different phases, such as permitting, and may take up to a few weeks to complete—especially during the busy summer months. Don’t wait until a major storm has been forecast before you install your standby generator! Try to do it during the spring or fall, before you need it (and, more importantly, before everyone else needs it!).

What type of generator will you be installing? Air cooled or liquid cooled? Is it natural gas or propane? Will you be receiving a gas meter upgrade? At Kolb Electric, we’ll talk you through your options and help make sure your standby generator does everything you need it to.

Whenever you have any sort of electrical work done, you’re not just buying the system—you’re also buying the company doing the install. With this in mind, it’s important that you know their qualifications as well as those of the technicians who will be installing your generator. Ask the following questions:

Kolb Electric has been in business since 1925, and all of our staff is licensed and trained to install Generac generators.

Standby generators require on-going annual maintenance, which Kolb Electric will provide with a service agreement. Make sure you also register your Generac generator with the manufacturer for warranty claims.

The lowest bid may sound appealing, but the deepest discounts won’t offset the costs of correcting an improper installation. When you see a huge price difference from one company to the rest, you can be sure something is being left out: load calculations, size inspections, and gas meter upgradesare just some of the areas where some unscrupulous contractors may cut corners and leave you up the creek when the big one hits.

Standby generators are designed to protect your biggest investment: your home. Take the time to get accurate answers regarding your system to keep your family safe.

38 million people in the U.S. that has migraines or study published in a 2016 issue of Brain shows that green LED lighting reduced pain intensity by 20 percent. In the study, “Migraine photophobia originating in cone-driven retinal pathways,” researchers at the Beth Israel Deaconess Medical Center set out to test whether or not colors can affect photophobia and migraine intensity. Photophobia is sensitivity to light and can be associated with pain and migraine exacerbation. Findings in a previous study fueled the motivation for this study. In the earlier study, the researchers found that blind participants experienced increased migraine pain when exposed to blue light.

Sixty-nine participants with migraines were part of the most recent study. Researchers studied the effects that exposure to white, blue, green, amber, and red low-intensity light had on their pain. Blue and red light were the worst—increasing pain by 18-19 percent. White and amber increased pain by 15 percent. Green was the only color that reduced pain.

Another green-light study found that exposure to low-intensity light from green LEDs reduced chronic pain and migraine severity. In this study, eight participants with fibromyalgia or migraines were given a green LED strip light, and five were given a white strip. Participants were asked to use their strips nightly for one to two hours for 10 weeks. Participants with green LEDs reported a 40-50 percent drop in pain.

The study was so successful for some that they asked to keep their green LED strip lights; they continue to use them in addition to or in place of medicine. In a study was published in a 2017 issue of Pain. The University of Arizona study, “Long-lasting antinociceptive (pain blocking) effects of green light in acute and chronic pain in rats,” found that rats experienced an increased tolerance for thermal and tactile testing methods. These tests measured how long it took for the rats to withdraw their paw when exposed to heat or pricked with a filament. Testing was completed under green or white light. The researchers found that after eight hours of green LED light exposure for five days it took much longer for rats to withdraw their paws. Effects of the green LEDs lasted for four days.

Rajesh Khanna, UA associate professor of pharmacology and senior author of the study, reports that, “While the pain-relieving qualities of green LED are clear, exactly how it works remains a puzzle. Early studies show that green light is increasing the levels of circulating endogenous opioids, which may explain the pain-relieving effects.”  In a UA article, “(Exogenous) Opioids, while having many benefits for managing pain, come with serious side effects.” These medications can also be addictive.

Researchers in this study are not advising people to stop their medications without speaking with a professional. However, it is possible, as in Lesneski’s case, that green LED lighting could eliminate the need for them in the future. “We need safer, effective and affordable approaches, used in conjunction with our current tools, to manage chronic pain,” Ibrahim said.
