General information
➜ Tubular fluorescent lamps HThere are range models that differ according to
design and size.
➜ IRC technology (Infra Red Coating) special coating the bulb wall reflects the heat ge-
nerated back onto the glowing coil order maintain
it the correct operating temperature. The average lifespan around
12,000 20,000 for lamps.
Fluorescent lamps can also found circular form
allowing for flat designs that produce rotationally
symmetric distribution light
➜ Compact fluorescent lamp
(Energy saving lamp ESL) KAs the name suggests, this type fluorescent lamp has
a compact design. The maximum output 100W, and the average
lifespan between 2,000 and 4,000 depending on
the type.

Fluorescent lamps are based low pressure gas discharge

earlier fluorescent lamps have now been eliminated thanks
to modern technology and the right choice fluorescent ma-
