There are a variety of reasons to practice group relamping, in which a set of lamps is replaced at a scheduled time, rather than spot relamping, in which lamps are only replaced when they burn out. Most of these reasons apply to fluorescent and high-intensity discharge (HID) lamps rather than incandescents, which have much shorter lifetimes.

• Group relamping requires much less labor per lamp than spot relamping. A worker might take as long as a half hour to retrieve and install a single lamp. If all the materials were on hand for a large number of lamps, a worker could move systematically from fixture to fixture and cut the required time to about 3 minutes per lamp. The process would also be less disruptive, because group relamping is usually done outside working hours.
• Group relamping is easy to schedule and delegate to outside contractors, who have special equipment and training.
• Group relamping provides brighter and more uniform lighting because lamps are replaced before their output has fully depreciated. Direct energy benefits result if the designer, anticipating group relamping, uses a smaller safety factor.
• Group relamping offers increased control over the replacement lamps, reducing the chances of mixing incompatible lamps—such as those with different color temperatures.

Economic comparisons typically show that group relamping has higher lamp costs but lower labor costs than spot relamping. One such comparison in Table 1 indicates a 31 percent overall savings from group relamping. This type of calculation is heavily dependent on the difference in labor costs between group and spot relamping. For example, if the group relamping cost of $1.50 per lamp jumps to $3.50, the balance tips in favor of spot relamping. Remember, however, the noneconomic benefits of group relamping discussed above when deciding between the two methods.

Group relamping has higher lamp costs but much lower labor costs, in this case providing a 31 percent overall savings. Group relamping also provides additional benefits in lighting quality and easier facility management.

T5HO & T8 Fluorescent High Bay Fixtures are specifically designed to replace conventional H.I.D. lighting in commercial / industrial applications. It’s an ingenious blend of technologies as it combines the advantage of T5 and T8 linear fluorescent lamps with the mounting flexibility of high bays. The Fluorescent High Bay is an environmentally friendly lighting solution because it exceeds the demands of today’s growing energy requirements.

The secret to these fixtures performance lies in the multifaceted, enhanced aluminum reflectors that encase each lamp and focuses the output for maximum intensity. Coupled with the excellent color rendering, lumen maintenance, and energy efficiency of today’s fluorescent, fluorescent high bay fixtures can be used in applications normally reserved for HID’s.

Standard 400-watt metal halide fixtures rated for 36,000 initial lumens lose up to 45% of their lighting ability through depreciation and fixture inefficiencies. When compared to only a 6% loss of the T5HO Fluorescent High Bay rated for 20,000 initial lumens, the maintained lumen output is virtually the same.

A four-light 54-watt HO T5 high bay requires only 239 watts as compared to the metal halide which consumes 454 watts, a dramatic 50% savings in energy usage. In addition, the fluorescent high bay produces brighter, more even illumination with features like instant on, built-in switching and low-temperature operation.

Fluorescent High Bay Fixture has been designed to be Contractor Friendly by including features that make it easier to install and maintain. The fixture accepts multiple suspension methods.

Fluorescent lights are classified by wattage, shape and diameter. The “T” in T5s and T8s refers to the tubular shape of the bulb, while the number refers to its diameter. Their light output is measured in lumens. Older fluorescent lights, like T12s and T38s, use a process called electromagnetic induction to produce light. However, this is less efficient than the latest technologies as of 2010; newer T5s and T8s use more efficient, cost-effective methods.

Governments have passed measures to prohibit the sale of incandescent light bulbs. The aim is to encourage use of more energy efficient lighting alternatives, such as compact fluorescent.

Congress bans incandescent bulbs

Massive energy bill phases out Edison’s invention by 2014.

The phase-out of incandescent light is to begin with the 100-watt bulb in 2012 and end in 2014 with the 40-watt.

All light bulbs must use 25 percent to 30 percent less 2014. By 2020, bulbs must be 70 percent more efficient than they are today.

Australia was the first country to announce an outright ban by 2010.

How should I clean up a broken fluorescent bulb?

Because CFLs contain a small amount, EPA recommends the following clean-up and disposal guidelines:

Before Clean-up: Air Out the Room

• Have people and pets leave the room, and don’t let anyone walk through the breakage area on their way out.
• Open a window and leave the room for 15 minutes or more.
• Shut off the central forced-air heating/air conditioning system, if you have one.

Clean-Up Steps for Hard Surfaces

• Carefully scoop up glass fragments and powder using stiff paper or cardboard and place them in a glass jar with metal lid (such as canning jar) or in a sealed plastic bag.
• Use sticky tape, such as duct tape, to pick up any remaining small glass pieces and powder.
• Wipe the area clean with damp paper towels or disposable wet wipes. Place towels in the glass jar or plastic bag.
• Do not use a vacuum or broom to clean up the broken bulb on hard surfaces.

Clean-up Steps for Carpeting or Rug:

• Carefully pick up glass fragments and place them in a glass jar with metal lid (such as a canning jar) or in a sealed plastic bag.
• Use sticky tape, such as duct tape, to pick up any remaining small glass fragments and powder.
• If vacuuming is needed after all visible materials are removed, vacuum the area where the bulb was broken.
• Remove the vacuum bag (or empty and wipe the canister), and put the bag or vacuum debris in a sealed plastic bag.

Clean-up Steps for Clothing, Bedding. etc.:

• If clothing or bedding materials come in direct contact with broken  glass or mercury containing powder from inside the bulb that may stick to the fabric, the clothing or bedding should be thrown away. Do not wash such clothing or bedding because mercury fragments in the clothing may contaminate the machine and/or pollute sewage.
• You can, however, wash clothing or other materials that have been exposed to the mercury vapor from a broken CFL, such as the clothing you are wearing when you cleaned up the broken CFL, as long as that clothing has not come into direct contact with the materials from the broken bulb.
• If shoes come into direct contact with broken glass or mercury-containing powder from the bulb, wipe them off with damp paper towels or disposable wet wipes. Place the towels or wipes in a glass jar or plastic bag for disposal.

Disposal of Clean-up Materials

• Immediately place all clean-up materials outdoors in a trash container or protected area for the next normal trash pickup.
• Wash your hands after disposing of the jars or plastic bags containing clean-up materials.
• Check with your local or state government about disposal. Instead, they require that broken and unbroken mercury-containing bulbs be taken to a local recycling center.

Future Cleaning of Carpeting or Rug: Air Out the Room During and After Vacuuming

• The next several times you vacuum, shut off the central forced-air heating/air conditioning system and open a window before vacuuming.

• Keep the central heating/air conditioning system shut off and the window open for at least 15 minutes after vacuuming is completed.
