The use of halogen globes
for practically anything is a widely
accepted practice. Among them the fixtures popularly
called downlights that are used for true color rendering. Also, stylish

those wires makes them possible to run unconcealed. But
when you consider efficiency it's a different ball game.

how light color temperature affects usage
Halogens : the
are the choice of the day for choosing low voltage
lighting. And halogens are great in that they provide a very even and
vibrant light. But they burn out without warning (very little fun
there), and they too need regular replacement.
this as an example: A typical $10 50W
halogen globe uses
around $30 worth of energy over its entire
life of approximately 1,000 hours. Over that lifetime that used energy
plus lamp costs will cost you around $11 per bulb. Not let's ompare
that to another typical bulb, but this time take a compact fluorescent
one. A $15 12W compact fluorescent will last about 3,000 hours and
provide similar light at a lifetime cost of lamp plus energy of $15
dollars. Over the same lifespan that a halogen light bulb
lasts ( whihc is 1,000 hours, remember) that's a cost of only
$5 per resulting in a saving of 60%.
Compact fluorescents are not
only much better
energy saving bulbs they also cost at least 3 times less to

both fluorescents and LED downlight even
True, halogen lights are
low voltage lighting
fixtures. But because their light is narrowly directed with a sharply
defined edge you need too many of them to properly light a room. And
with any halogens - not just spots - heat
is also produced at the adaptor or transformer and that is a
significant though somewhat hidden heat output.
halogen down-light myth is persistent. But for room
you should consider compact fluorescent bulbs instead. They reliably
last longer and cheaper to run. And because you need to use too many
halogens for a decent
lighting fluorescents will be even less overall wattage and produce
less heat. Learn more about

of halogens: handling
To add insult to injury, replacing a halogen bulb is a very
delicate operation. You cannot smudge it with your fingertips. If you
do the slight deposit of grease will burn from the too high heat
resulting in the speedy loss of the bulb. Halogens, as the saying goes
- are very delicate creatures.
