Standard Incandescent Vs. Halogen

How does Standard Incandescent work?

Tungsten is deposited on the walls of the bulb reducing
light output. Over a relatively short time the filament gets
thinner until it finally breaks.

  

How does Halogen work?

Halogen gas causes the evaporated tungsten to redeposit
on the filament. The high pressure within the bulb slows
down the deterioration of the filament
     
Color rendering of Standard Incandescent

Low color temperature and 100 CRI casts a warm light
that provides good color rendition of human skin tones,
and other warm colors such as red and orange.		 Color rendering of Halogen

High color temperature and 100 CRI. Their light contains
more blue and green than a standard bulb causing the
halogen light to appear whiter and brighter. Also if you will
notice in Fig. B-2, you can see the clarity and gleam that
halogen brings out in the jewlery.
     
Energy consumption of Standard Incandescent

Produces light by heating a solid material until it glows.
Most of the energy consumed is given off as heat,
resulting in low LPW (lumens per watt) performance.		  

Energy consumption of Halogen

Uses a low voltage system that operates efficiently at lower
wattages than line voltage systems.
     
Beam control for Standard Incandescent

Standard Incandescent has very poor beam control.
This type of lamp is better if you would like a wider span
of light over a particular area (As shown in fig A-1 and
A-2.). That being said, Standard Incandescent is a good
general lighting source.		   Beam control for Halogen

Produces large amounts of light from a very small area
causing excellent beam control (As shown in Fig. B-1).
With Halogen, shadows are more defined, creating a more
dramatic effect. This paired with the good color rendering
makes Halogen an excellent accent lighting source.
