Fluorescent Emergency Lighting Ballasts

Emergency ballasts provide immediate backup lighting when normal AC power fails. In the event of a power failure, these ballasts switch instantly to emergency mode to maintain operation of one or two existing lamps for a minimum of 90 minutes. When AC power is restored, emergency fluorescent ballasts automatically recharge, in preparation for the next AC outage. The BAL emergency ballasts allow the same fixture to be used for normal and emergency operation.

BAL emergency ballasts are designed to operate most single or bi-pin fluorescent tubes, 2-pin or 4-pin CFL’s and fluorescent U-shaped, HO, VHO, energy saving, circline, twin-tube, quad and triple twin-tube lamps.

Light Pollution: The View from Above

Many of us have admired a fantastic view from an airplane takeoff or landing. We find ourselves looking down on thousands of city lights shining like stars on the ground. As amazing as the view may seem, we are actually looking at a form of light pollution.

Light pollution is excessive or obtrusive artificial light, which includes light trespass, over-illumination, glare, and sky glow. These conditions waste energy, can disrupt ecosystems, cause adverse health effects and obscure stars and astronomical observations. With the need for safety, security and visual acuity at night, what can be done to minimize light pollution?

The majority of light pollution you see from above is considered sky glow. By definition, sky glow is the result of light that is emitted directly upward by luminaries or reflected from the ground, producing a luminous background. When outdoor lighting is poorly designed and installed, portions of light shine upward where it is not needed. Sky glow is the visible effect of wasted light and wasted energy.

Communities around the world have started enforcing “dark sky” regulations that restrict the amounts of light that can be directed upwards. The best way to control this upward sky pollution is to install lighting fixtures that direct light to needed areas, saving energy and reducing glare. A full cutoff fixture, (fig. 1.) when installed correctly, reduces the chance for light to escape above the horizontal plane. Their design minimizes the visibility of the lamp and reflector within, so the effects of glare are also reduced. It is also important for fixtures to be properly spaced, for even greater lighting efficiency.

The End is Near for Mercury Vapor Ballasts

Effective January 1,2008, mercury vapor ballasts can no longer be manufactured or imported into the United States. This will include lighting fixtures that incorporate these mercury vapor ballasts. This new provision is part of the Energy Policy Act signed into law in August 2005 in order to address efficiency matters regarding energy generation, transmission, distribution and consumption.

Mercury vapor lighting can often be found in outdoor lighting applications such as parking lots, streets, landscapes and commercial properties. As technology has developed, these mercury vapor lighting systems have become inefficient in comparison to other solutions. The intent of this new law is to eliminate the use of these inefficient systems and replace them with more environmentally friendly technology, such as metal halide, high pressure sodium and fluorescent lighting systems. After January 1, as mercury vapor ballasts fail, fixtures and ballasts will need to be replaced. The initial cost of replacing the lighting systems will be higher, but in the long run they will save the consumer energy and money.

Though the ballasts are being outlawed, the mercury vapor lamps( Mogul base, Medium base, Reflectors, and self ballasted) will still be legal. These lamps will still be used in existing mercury vapor lighting systems that are still in operation. Though Mercury vapor lamps can also be run on metal halide ballasts, switching to a complete metal halide lighting system will give you a much higher quality of light as well as being energy efficient.

The Decline of the Incandescent Bulb?

For almost 130 years now consumers have been buying and using the good old incandescent household bulbs day in and day out. In that time there has never been any major change to the technology of the bulb. The bulb’s inefficient use of energy has never been a big factor and the uptake of more energy efficient, compact fluorescent bulbs has been slow. It is clear the incandescent bulbs, converting only 5% of the energy they receive into light, falls well short of the energy-saving compact fluorescent bulbs. Compact fluorescents use 70-75% less electricity, last about 10 time longer, produce fewer greenhouse gases and save consumers about $30 over the life of the bulb. So why has only 6% of households decided to break the “incandescent habit?” When compact fluorescents were first introduced the technology was not yet perfected. These bulbs often took a few seconds to start, were perceived as funny looking, could not be dimmable and did not fit into standard fixtures. Though there have been many improvements to the compact fluorescent, they still have a much higher cost associated with them than the common incandescent. In recent times some big names have been shedding a lot of light on the shortcomings of the incandescent bulb and their future may be changing.

Why would anyone pay $5.00 for a light bulb?

As consumers, we are often faced with the decision to spend a little more up front, to realize a savings benefit, over time. A high efficiency furnace or air conditioning system can be more expensive to purchase initially, than a standard heating or cooling system. However, the cost to operate the less expensive unit takes its toll in electrical bills that give you anxiety during the winter or summer months. We dial down in winter and up in summer, because we do not want to pay for the electricity it takes to run the units. Is there something wrong with this picture?

The same hold true for light bulbs. How often have you heard “Turn off the lights, you’re wasting electricity.” There is however, an energy efficient light bulb known as the Compact Fluorescent. Commonly called CFL’s,

Compact fluorescents use 70-75% less electricity, last 10 times longer, produce fewer greenhouse gases and save you about $30 over the life of the bulb. So why have only 6% of households decided to break the “incandescent habit?” When compact fluorescents were first introduced the technology was not yet perfected. With today’s technology, CFL’s light instantly, are dimmable, produce a soft, indoor light, and come in a variety of shapes and sizes. CFL’s are self-ballasted and operate in any standard incandescent table lamp or household fixture. For optimum energy efficiency, CFL ceiling and wall fixtures are now available at Lighting Supply.

Because the initial cost of high efficiency bulb plus the electricity to operate it, are much less over the life of the bulb, than the cost of a traditional light bulb and the high amount of electricity it consumes, by hundreds of dollars. Hundreds of dollars saved plus an environmentally responsible decision. What decision could be easier? The perfect choice for business and home, we offer hundreds of different CFL options to fit your lighting needs. Invest that $5.00 and start saving money and our environment, today.
