Q: What are your HOURS of operation?

A: 6 AM to 3:30 PM Monday through Friday.

Q: Is there an after hours EMERGENCY SERVICE?

A: There is a person on call 24 hours a day for emergency purposes. CALL: 630-844-3274 to reach us in an emergency.

Q: What does it mean WHEN THE LIGHTS GO OFF AND ON?

A: When a light is flickering or going off and on this is called cycling, which means that the lamp is at the end of its life and is drawing too much current. The ballast senses this and shuts the lamp off for a short amount of time. These abnormal currents will cause ballast heating and thereby reduce ballast life.

Q: What is LIGHTING MAINTENANCE?

A: Lighting maintenance means action to recover light loss due to the following:

  • Lamp lumen depreciation
  • Dirt accumulation on lamps and luminaries
  • Lamp burnouts
  • Luminaire surface deterioration
  • Room surface dirt accumulation

Q: How do you plan a LIGHTING MAINTENANCE PROGRAM?

A: The most effective method of consistently maintaining illuminance and lighting quality at the lowest operating and maintenance cost is through a planned program. Planned lighting maintenance entails group relamping, cleaning lamps and luminaries, replacing defective or broken components on a scheduled basis.

Q: What is RETROFIT?

A: A retrofit of lighting upgrade is when both ballasts and lamps are replaced. The advantage being the new ballasts and lamps would be more high-tech then what is already in place, therefore you would have more light for less energy consumption.

Q: What is a RELAMP?

A: Group relamping entails replacing all of the lamps in a system together after a fixed interval, called the economic group relamping interval. Group relamping should take place at approximately 70% to 80% of rated lamp life.

Q: What is the TCLP TEST and WHAT DOES IT MEASURE?

A: TCLP is one of the Federal EPA test methods that facilities use to characterize their waste as either hazardous or non-hazardous for the purpose of disposal. TCLP is an acronym for Toxicity Characteristic Leaching Procedure. It is performed by environmental testing labs. The TCLP test does not measure total mercury content; rather it measures the amount of mercury, which is expected to seep or leech into groundwater if a waste is landfill disposed. In the TCLP test, lamps are crushed into small pieces and mixed with an acidic solution. The acidic solution is then filtered from the lamp pieces. If less that 0.2 mg of mercury are found per liter of acidic test solution the waste is characterized as non-hazardous waste under federal law. In most states there are no special disposal requirements for non-hazardous waste lamps.

Q: Why do fluorescent lights CONTAIN MERCURY?

A: Mercury is used to generate light in all fluorescent lamps. When electric current passes through mercury vapor, the mercury emits ultraviolet energy. When this ultraviolet energy passes through the phosphor coating, it produces light very efficiently. Today, there are no known energy efficient substitutes for mercury in fluorescent lamps. As the lamp operates, the mercury is slowly absorbed by the various internal parts of the lamp. Because mercury is consumed during operation, a certain amount of mercury is necessary to achieve a long lamp life. The significantly reduced amount of mercury in Ecolux lamps is designed to optimize the balance between long lamp life and environment concern.

Q: How high do your BUCKET TRUCKS REACH?

A: TCL Electrical & Lighting has a fleet of trucks that reach up to a height of 100 feet.
