For centuries man lit his night with an oil lamp that created only about 1/10th of a lumen per watt (a very small amount of light produced for the expenditure of a standard unit of energy). Then in the late 19th century the incandescent light bulb was invented and that eventually provided about 16 lumens per watt. In the late 1930s the fluorescent lamp became a reality and gave us an amazing average efficacy of about 70 lumens per watt. Now in the early 21st century still another revolutionary development is taking place – light emitting diodes (LEDs) are or will soon give us 300 lumens per watt. Think about the amount of change in the way we have lit our homes, offices, stores, factories, and streets in just the last 20-30 years. It is nothing short of astonishing and you can bet that more change is on the way in how we light the way we live. Continue reading »

I was disappointed at the number of myths about sunglasses that were told to me by multiple, yes, multiple, supposedly knowledgeable sales people.

led traffic light green 200x300 LED Traffic Lights Cant Melt Snow

Put this one in the “didn’t see that coming” bin. Virtually everywhere you drive these days chances are you will see one or more LED traffic lights at important intersections. They’re the ones that look like a pattern of bright dots.

Cities around the country have installed these new traffic lights for several very good reasons. They are very energy-efficient using about 90% less energy than their incandescent counterparts and, more importantly, they last tens of thousands of hours, thus saving municipalities a bundle in maintenance costs.

Wisconsin, for example, which has put LED traffic lights at hundreds of intersections, saves about $750,000 per year in energy costs. LEDs installed seven years ago are still burning, while most incandescent bulbs have to be replaced every 12 to 18 months.

burst outdoor 300x247 Where Does That Sconce Go Anyway?A wall sconce (sconce, for short) is an ornamental bracket fixed to a wall for holding a candle or an electric light of one kind or another. The electric light source could be incandescent, xenon, halogen, fluorescent, or even LEDs.

Long ago, wall sconces were primarily mobile lighting devices which were carried to light the way throughout a home or passageway. These wall sconces were frequently hung on a wall or over a fireplace where they were readily available for the homeowner’s use. Today, wall sconces are attached to a wall to provide permanent illumination. But where do they go exactly?

Recessed downlights should not be used to light your face while standing at a mirror in your bathroom because the light coming from these fixtures will only cause harsh shadows on your face. Instead, wall-mounted vanity light fixtures attached above the mirror and/or on both sides of the mirror, or backlit vanity mirrors (a very neat option – especially if wall space is limited) should be used. That way, shadows on your face can be minimized. Recessed downlights can be used in other parts of the bathroom for general lighting but not for task lighting at the sink area – unless, of course, you want to look years older or like Bella Lugosi in makeup.

Light = Energy
Poorly lit home gyms tend to lack energy whereas a bright space with a generous amount of light is generally more inviting for exercise and can be crucial to creating just the right environment for a vigorous or energetic workout.

Natural Light is Best
Natural light coming from plenty of windows and skylights is the best source of light for a home gym. If the natural light in your home gym is only minimal or non-existent, try using good fluorescent lighting that emulates sunlight. This means that the fluorescent light bulbs should have a high color temperature of 5000K-5500K and very good color rendering of 82 or higher.
