- Why Use Them?
Downlights are recessed ceiling lights which have specific uses
in certain locations around
the house or office, where other types of lighting are impractical or cannot
create the same atmosphere.
Bathrooms and kitchens in particular sometimes require direct light that is simply
inconspicuous, giving a clean
appearance to a room with out
for unsightly and
cumbersome light fixtures
that don't integrate well with its immediate surroundings.
It is quite common for
recessed downlights to be used in conjunction with light dimmers, which can rapidly and easily affect the
amount of light produced and
alter the feel or atmosphere of a room.
Downlight manufacturers these days design these ceiling lights to meet the required
quality standards for use in
certain areas. There are several
types of downlights manufactured for different uses and available in different
In the past, the only downlights used had been the types with standard screw in outlets that applied
floodlight lamps. These type of
downlights were inefficient in terms of power consumption and the amount of replacement bulbs
As a result of their inefficiency, manufacturers
focused their efforts towards the improvement of dichroic downlights, which use halogen lamps, last much longer and are a lot more energy efficient.
- The Two Main Types
Two main types of downlights exist for most applications. Mains downlights are
utilised when much more
required, and they operate at
a higher voltage (240V)
and therefore create heat which is far more direct.
These downlights are much less
high-priced, but require
a larger investment in lamp replacement
expenses. On the other hand
there are low voltage (LV)
downlights which happen to be frequently paired with a transformer to assist dissipate some of the heat created, and
further protect the circuit
for additional manage.
Low voltage downlights are
used in conjunction with dimming
controls too. A
frequent installation for downlights
in showers employs a mirrored glass or die cast surface that sits flush with the
the actual lamp is recessed
numerous inches above the
These lights call for slightly added
insulation and fire protection
as a result of their proximity to
steam, heat and water spray that can be a considerable fire hazard.
- The Future
The other widespread use for downlights is for accent lighting on
paintings and art objects that benefit from direct light. In this way, downlights and
enclosed spotlights support separate such objects from surrounding walls
and bring a lot more character to a specific
The kind of lamps used in downlights is changing over
time, as standard
halogen lamps produce
carbon emissions and a
larger number of them are required
to create exactly the same quantity of light. The more light fittings required to
be used, the greater the heat created.
There is ongoing development in the downlight
market by downlight manufacturers. In recent years some of their results have been energy
efficient 12V halogen lamps, LED
downlights and CFL fluorescents that use substantially much less energy and last as much as 50 times longer than original halogen
LED is a relatively new technology which is definitely
expected to eventually
replace lots of
