1. How does Lango Induction Light work?
Lango Induction lamps consist of a sealed glass tube filled with an inert gas, magnets encircling the tube and a high efficient
electronic circuit board (called a ballast but technically a generator) that provides power. When current is applied it induces the
magnets, causing acceleration of free electrons in the inert gas, which collide with mercury atoms and excite the electrons.
As the excited electrons from these atoms fall back from a higher energy state to a lower, stable level, they emit ultraviolet radiation.
The UV radiation created is converted to visible light as it passes through a phosphor coating on the inside surface of the tube.
2. Whether Lango Induction Lighting is environmentally friendly?
Yes, Lango Induction lighting is a green choice for the environment because of its long life span and working techonology.
Lamps don't need to be changed often, so less waste and pollution is created from fixture maintenance and replacement.
Induction lighting is relatively efficient, which reduces energy and fossil fuel consumption. Induction lights contain the mercury
which is in a solid state, so bulb breakage is not a concern.
3. How Lango Induction lights save energy?
The electronic ballasts equipped with Lango induction lamps and fixtures are all low working frequency which is 230Khz, and
they generate lights output high up to 80-100lm/w, and the specialized fixtures for induction lamps also help increase the light output
and reduce the waste of lights. Compared with traditional lamp sources, Lango induction lights could save energy around 50-60%.
4. How long does Lango Induction Lighting last?
Induction lamps are known for the long lifespan, which is typically up to 100,000 hours. This means 11 years of operating life.
5. What temerature can the Lango induction lights operate at?
The majority of Lango induction lights operate from -25 centigrade degree to +50 centigrade degree,
that is -13 F degree to 122 F degree.
