Incandescent/yellow light bulbs have been around since the beginning
of light bulbs. The make-up of an incandescent bulb is simple, there is a
frosted bulb that illuminates because a carbon filament coil heats up
and causes the frosted bulb to glow. Incandescent light bulbs have been
used since they were invented 130 years ago.
Heat Dangers
The heat that is generated from even the lowest watt of incandescent
light bulb is extreme. If a light bulb burns out you should wait a few
minutes to change it out because you can burn your fingers. The current
that runs through the coils inside the bulb generates heat that is
transferred to the glass bulb because glass is a good conductor of heat.
Breakage
The glass that is used to make incandescent light bulbs is very thin,
This helps the light to shine clearly through the bulb, whether it is a
frosted bulb or a clear or colored bulb. Because of this it is
extremely fragile and a very slight bump can cause the light bulb to
break. The small shards of glass that fall from the shattered bulb can
get into an eye, or be stepped on and difficult to remove. Additionally,
if the light bulb breaks inside the socket it is dangerous to try to
remove the light bulb from the fixture. A good method to remove such a
bulb is to use a potato, push it hard onto the broken end of the bulb
that is in the fixture and turn the bulb out of the socket.
Exploding or Bursting Light Bulb
There is air inside of a light bulb. When the air is very cold inside
a light bulb the heat that comes from the copper filament can cause an
adverse reaction on the air inside the bulb causing it to expand too
rapidly and thus bursting the glass of the bulb. If someone is near the
bursting bulb they can be hit by the glass shrapnel that is broken free.
Eyesight Dangers
Lights are very bad for the eyesight. Staring into an incandescent
light bulb can cause severe eye damage including cataracts. It is
necessary to ensure that your bulbs are covered with a shade or a
covering to help mute and filter the bright light of the bulb. The light
of even a 40 or 25 watt light bulb can be enough to harm your eyesight.
Do not stare directly at an incandescent light bulb.
Environmental Dangers
Although an incandescent light bulb is not chemically dangerous they
are authorized to be put right into the trash and then hauled away with
your local garbage truck. Once the bulb gets to the landfill it becomes
part of the problems that have been occurring in the country. There is a
lot of trash being built up and light bulbs do their part in the ever
increasing bulk of trash that big cities and small communities are
working to eliminate.
