What is considered
hazardous waste?
Colorado Lighting, Inc. is committed to providing our customers
with the latest rules and regulations for lamp and ballast disposal
on a state as well as federal level. Please refer to our Recycling
information for more details.

What does it mean when lights
go off and on?
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.

What is lighting maintenance?
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

How do you plan a lighting maintenance
program?
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.
For more detailed information refer to the IESNA Lighting Handbook.

What is retrofit?
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.

What is a relamp?
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.
For more detailed information refer to the IESNA Lighting Handbook.

What is the TCLP test
and what does it measure?
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.

Why do fluorescent lights contain
mercury?
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.
