LED streetlights are great for the environment. They consume much less energy than standard high-intensity discharge (LED streetlights. What some cities have failed to consider, however, is that while LED streetlights are capable of emitting different colors of light, not every color should be used in public outdoor spaces. Bright blue-rich white light can cause some issues for residents, local wildlife, and night sky visibility. When it comes to streetlights, the warmer the color/correlated color temperature (

studies showing that it can even aid in IBS as well as migraine and cancer prevention.

Throughout the day, light changes from a warm white color at dawn to natural white then to a cool white in the afternoon, back to natural white, and eventually to an ultra warm white color at sunset. Our bodies are used to this cycle of light. Artificial lights that deviate from the natural lighting cycle can throw off our circadian rhythms. The National Institute of General Medical Sciences states that, “Circadian rhythms are physical, mental and behavioral changes that follow a roughly 24-hour cycle, responding primarily to light and darkness in an organism’s environment.”

According to healthybuildingscience.com “. . . different types of light trigger different physiological effects. Blue/white light, akin to a bright midday light, suppresses melatonin and increases serotonin, this light is great for activity. Conversely red/orange light triggers melatonin in preparation for going to sleep. If everything is in balance, the body will generate dopamine, serotonin, cortisol and melatonin in the right quantities at the right time of day.”

On their website, the IDA cites important information from a report, this happens “. . . because blue light scatters more within the human eye.”  While it’s not directly causing harm to someone’s health, glare decreases driver safety and can lead to traffic accidents.               

At night, blue light used outdoors can also wreak havoc on ecology. Introducing light with a CCT that’s close to daylight essentially changes the daily cycle that plants and animals are used to. They depend on this cycle of light and dark for hunting, reproduction, sleeping, migrating, and protection. Nocturnal animals have suffered greatly from cool white light at night; the IDA

Because blue light has a larger reach, cool white LED lights used outdoors at night can contribute to light pollution, or brightening of the sky. This decreases the visibility of stars and can have a negative effect on astronomical research. If cool white LED lights are used, they should be shielded or aimed directly downward to prevent light pollution.

Warm white LED street lights and parking lot lights—with a CCT of 3000K or less—are a much better option for public outdoor areas. They emit a much smaller portion of blue light—which is unnoticeable to the eye—and are currently the best options available for street lighting.

If you are deciding whether you want to install solar panels or not, there are a few interesting and enlightening facts to consider. Not only should you think about the cost of solar panels, which can be way more affordable than you realize, especially when you take in to count your electricity expenses going down considerably, there are a few other things to think about, as well:

The kitchen is one of the busiest and most heavily-used rooms in your home. When it comes to fires, it’s also perhaps the most dangerous. With various fluids being used, such as oils and water, along with electrical appliances, heat sources, and more, it doesn’t take much for a simple mistake to lead to a potentially devastating blaze suddenly bursting to life. When it comes to kitchen safety, knowledge and care can go a long way, as can preparation should a fire ever start. Check out these valuable tips for learning how to avoid electrical fires in the kitchen and how to deal with one that starts.

The kitchen frequently uses water, oils, greases, and other substances alongside electricity in numerous situations. Your appliances all likely run on electricity, including your refrigerator, garbage disposal, dishwasher, and possibly even your stove and oven. While most of these devices are designed to keep all potentially-sensitive electronics away from any possibly damaging fluids, you likely still have exposed electrical plugs, extension cords, and more running along your countertops.

It doesn’t take much for a kitchen fire to start. Perhaps the most common type is a grease fire. If you ever work with hot oil on the stovetop, you’re probably well aware of how dangerous this substance is. In addition to having an extremely high burn risk, a single spark could cause a grease or oil source to quickly ignite, becoming a massive and difficult to deal with ordeal. This means you should be extremely cautious when using electricity to cook. Regularly inspect your plugs and cords for any signs of wear or fraying, and you should immediately stop using a device if you find any exposed copper at all—the risk of a potential fire far outweighs the cost of replacing a broken appliance.

Your microwave is a particularly interesting appliance in that it reacts violently with any metal placed inside it. If you’re not paying attention, it’s not difficult to accidentally stick something that isn’t microwave-safe in there, and usually by the time you figure it out it’s already too late.

If a fire does erupt in your microwave, opening the door should NEVER be the first thing you do. Fires need oxygen to breathe, and opening the door allows the oxygen to get in quickly, allowing the fire to grow and spread, and your problem will only get worse. Instead, the first thing you should do is unplug the device if possible and allow the fire to suffocate itself and go out before opening the door. Before you do, be prepared to dial 911.

Putting out a fire in your kitchen is rarely as easy as throwing water on it. In fact, in most cases water actually makes the problem worse. If you have an electrical fire, throwing water on it will probably only encourage more sparking and increase the chances of injury by electrocution. If you have a grease fire, throwing water on it will only cause the grease to splatter and continue to burn, potentially spreading the fire further (after all, water and oil don’t mix).

If you have a grease fire in your kitchen, the best way to put it out is to smother it and deprive it of oxygen. If the fire is contained in a pan, the best way to smother it is to use a metal lid to cover the pan and cut off the oxygen supply. If you don’t have a metal lid, a large baking sheet will do the job. Just make sure you use oven mitts or some other form of hand protection when you finally remove it. If the fire spreads outside the pan, cover it with salt or baking soda to quickly and effectively put the fire out. These substances are made from non-flammable material, and will quickly cover and suffocate the fire from oxygen if applied properly. Electrical fires can generally be fought the same way, but you should always move to unplug the device first if possible. You don’t want to keep sending electricity through a short any longer than you have to.

Finally, every kitchen should have a fire extinguisher in it. If you don’t, pick up a small Class B or Class ABC unit from your local hardware store (they’re not very expensive). These devices are approved to fight grease and kitchen fires because the retardant they use is dry, thus meaning you won’t have to worry about splattering that you would otherwise face with a different type.

It might be hard to believe, but even with as cold as it’s been, spring is on the way! And while you’re out enjoying the outdoors, the Sterling electricians at Kolb Electric want to bring you some electrical safety tips to make this spring safe and fun!

Keep power cords away from water – you probably already know this, but water and electricity don’t mix. Any time you’re dealing with electricity, make sure you’re working in a completely dry environment. You should also consider testing your GFI outlets.

Beware of power lines – if your spring cleaning involves getting up on a ladder or using a long-handled pool-cleaning tool, make sure you know you’re clear of power lines before you start. Power lines are interesting—if you were to hang from one without your feet touching the ground, you would be safe. However, coming into contact with power lines while you’re standing on the ground is a different story, as the electric current will travel through you on its way to the ground. Note that if the power lines are low enough, this could happen even if you’re just standing under them!

Always call before you dig – underground power lines are just as dangerous as overhead power lines, and since you can’t see them, it’s almost impossible to know where they are! If your spring plans involve digging of any kind, like adding an addition to your home or even planting a tree, make sure you call to confirm that it’s safe to do so!

Keep materials, tools, and all body parts at least 15 ft away from overhead lines – like we said above, power lines can strike you even if you’re standing too close to them. 15 ft is the safest minimum distance, so make sure you’re aware of this, especially if you’re working on the roof.

Never fly kites or model airplanes near power lines – we keep harping on the power line issue because they can be very dangerous if you’re not careful. If you have a kite or model airplane that ends up getting tangled in power lines, don’t try to get it down yourself—call your local utility provider for assistance. As a side note, make sure you never use any metallic materials in your kite—these can conduct electricity back to you.

Inspect power tools and electric lawn mowers before every use – frayed power cords, broken plugs, and weathered or damaged housings can make your equipment dangerous to use, so don’t use anything until it has been repaired properly. When not in use, keep these tools unplugged and store them in a dry area.

Watch out for power lines hidden behind foliage – before you trim tree limbs and shrubs, make sure there are no power lines hiding behind them. If you are concerned about tree limbs growing on or around overhead power lines on your property, call your local utility provider.

Keep your electrical box clear – you know that large, green, ground-level box you may have in your yard? That box houses the components of an underground electrical system. Keep it clear of vegetation and other permanent structures, as utility workers may need to access the underground lines and equipment during unplanned outages or routine maintenance.

Do not use electric mowers on wet grass – as we said in the beginning, water and electricity are a dangerous combo. Only use an electric mower on dry grass, and if you need to use an extension cord, make sure you use an insulated cord designed for outdoor use and with the correct power rating for your equipment.

Treat all power lines the same – some power lines are high voltage, some are low voltage. For safety, treat all power lines as if they are harmful—because chances are, they will be!
