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.

Thunderstorms pose a safety hazard in several ways. Lightning is the most dangerous part of a thunderstorm, and it kills more people than hurricanes and tornadoes combined. Thunderstorms produce heavy rain, which can cause flash flooding. The strong winds from a thunderstorm can also cause widespread damage. Each of these components requires specific precautions to minimize their danger.

A thunderstorm typically has a diameter of 15 miles and lasts for 30 minutes, which is much smaller than a hurricane or winter storm. The National Weather Service places specific criteria on a severe thunderstorm. These include thunderstorms that produce hail with a diameter of at least ¾ inch, wind gusts of at least 58 mph or a tornado. Severe thunderstorms comprise about 10 percent of all thunderstorms.

The NWS recommends that you stay indoors for 30 minutes after the last clap of thunder when you hear thunder less than 30 seconds after the lightning. This rule is known as the 30/30 lightning safety rule.

Avoid taking emergency shelter in structures that are vulnerable to high winds, such as a mobile home. Outdoors shelters such as sheds, pavilions and golf’s typically will not protect you from flying debris and lightning. Avoid and report downed power lines. Bring pets and livestock under shelter to protect them during hailstorms.

We hear a lot about LEDs these days, but is there a place in the market for their fancier, pricier cousins, the OLEDs? Organic light emitting diodes have yet to find a niche in the market, but if and when they do, they’ll have to overcome stiff competition…

This Valentine’s day, show your partner how deep your love runs for him or her by cleaning all the neglected kitchen appliances! Chocolates, flowers, and jewelry are nice too, don’t get us wrong. It’s just that serious cleaning says a lot about how much a person cares. By tackling these uncharted territories, not only will the love your partner has for you grow, you may even rekindle the love you once had for your home. That’s a whole lot of love going around.

Can you remember the last time you cleaned the inside of your refrigerator or behind it? It isn’t the easy appliance to maneuver around, so it’s likely that you haven’t cleaned behind it since you moved in. To clean your refrigerator, first pull it out so that you can mop up the dirt, debris, and gunk that’s been left behind. Then, vacuum the coils, which are located either behind or beneath your refrigerator.

All refrigerators are equipped with door gaskets to prevent cold air from escaping. If you have loose gaskets, read through your owner’s manual to find out the replacement part numbers. Your local hardware store should have gaskets in stock.

Make the outside of your fridge sparkle with a solution of equal parts water and white vinegar. If you have a stainless steel fridge, rub in the direction using either a paper towel or a soft wash cloth.

Now that the outside of your fridge looks brand new, it’s time to tackle the other not-so fun part, which is the inside. Clean all shelves and crispers. Perhaps you can use this time to throw away all your expired foods and beverages that you forgot existed.

Even if you have the luxury of owning a self-cleaning oven, some work is still required on your part. Using a solution of equal parts water and vinegar, wipe down the door hinges and frames. You can tackle the particularly rough spots with a some baking soda and a sponge.

How to Clean Your Stovetop:

Soak your burners with hot, soapy water for a few hours, and then scrub. The drop plate may be the dirtiest component of your stove. Before your scrub this area, use a vacuum to get out all the accumulated gunk.

To loosen up all the baked-on foods in your microwave, fill a microwave-safe container with water and heat it until it boils. Wait a few minutes before opening the door so that the steam can do its job; then wipe.

We know how counter-intuitive this sounds, but trust us – it’s a task that needs to be done! Your dishwasher works day in and day out to clean your dishes; it’s only a matter of time before all the gunk accumulates.

If your planning to cook dinner for your partner this Valentine’s Day, he or she will notice how sparkling-clean the plates are!
