One of Philips Lighting’s leading Green Flagship products, the ALTO II lamps’ long-lasting, energy-efficient, and environmentally-conscious product design fully promotes sustainability by helping to reduce CO2 greenhouse gas and mercury emissions as well as minimize replacement and disposal efforts.

How does fluorescence lamp work?

A fluorescent lamp generates light from collisions in a hot gas (‘plasma’) of free accelerated electrons with atoms– typically mercury – in which electrons are bumped up to higher energy levels and then fall back while emitting at two UV emission lines (254 nm and 185 nm).

What do you mean by fluorescent lamp technology?

fluorescent lamp, electric discharge lamp, cooler and more efficient than incandescent lamps, that produces light by the fluorescence of a phosphor coating. The inside of the tube is coated with phosphors, substances that absorb ultraviolet radiation and fluoresce (reradiate the energy as visible light).

What is an alto fluorescent lights?

VHO – Very High Output. ECO – Low Mercury (Sylvania & GE) ALTO – Low Mercury (Philips)

Why mercury is used in fluorescent lamps?

It is useful in lighting because it contributes to the bulbs’ efficient operation and life expectancy. Fluorescent and other mercury-added bulbs are generally more energy efficient and last longer than incandescent and other equivalent forms of lighting, except for light-emitting diode (LED) lamps.

What does DX mean in fluorescent bulbs?

daylight
“DX” probably means daylight, but, then again, you have to compare the Kelvin rating. 6500K light is a very clean light. Beautiful lighting, but ALL bulbs in a room, should be the same Kelvin rating.

What does T8 stand for?

What does “T8” mean? The “T” designation in fluorescent lamp nomenclature stands for tubular — the shape of the lamp. The number immediately follow- ing the T gives the diameter of the lamp in eighths of an inch.

How many watts is a fluorescent tube?

1. Energy Consumption
