2. LED Bulbs
• “LED” is the abbreviation of
“light-emitting diode”. It is a
semiconductor light source
which could emit light when
a current moves through it.
• An LED bulb is a lighting bulb
that uses an LED chip to
convert electronic energy
into light.

3. CFL Bulbs
• CFL (compact fluorescent
lamp) is a fluorescent
lamp, using a tube curved
or folded to fit into the
base of the bulb which
has a compact electronic
ballast in it.

4. Incandescent Bulbs
• An incandescent bulb is an
electric light that emits light
with a filament wire heated
to a high temperature until
it glows by consuming
electrical energy.
• The incandescent bulb must
be the earliest electric bulb
in human history; however,
energy experts claim that
the incandescent bulb
should be replaced by other
more energy efficient bulbs
and become a thing of the
past.
