Stretch ceilings are good that, as a rule, do not impose specific requirements for lighting equipment mounted on them.Fixing chandeliers carried out as a conventional or made of drywall or ceiling suspension system.Yet it is desirable that spotlights for ceilings meet some specific requirements, because they are mounted in such a way that the majority of the length of their body is in the space between the base surface and the plane spanned film or matter.Visible is only the ring framing the halogen lamp, ceiling and windows.
Requirements to be met by spotlights for ceilings, in fact, not unique, it meets the majority of lighting devices of this type.Firstly, they must be round, at least in their "landing site."Trim, that is, the ceiling frame can be any shape, but especially the principle of the device is a stretch ceiling requires a round shape.
Second, built-in lights for suspended ceilings shall be provided with a mounting flange at least a centimeter wide.When installing lighting fixtures need to isolate it from the surrounding material that is PVC film or matter, otherwise they will be exposed to heat and can change their color.If the ceiling film, there may be more serious consequences, such as breach of its integrity.To use special insulation ring of heat-resistant porous material (that's something they should cover and flange).
Third, spotlights for ceilings, insulation should be light inside of the body, or the rays entering the space above his plane, it will shine through, creating a parasitic halos.This, of course, not too terrible defect, but more beautiful is obtained when the light goes out, where necessary.
Fourth height recessed luminaire should not be large.The smaller it is, the higher you can raise the suspended ceiling, and it is sometimes very important (especially in model homes).
Fixing to the base surface by means of an adjustable rack.
Spotlights for suspended ceilings can be of simple design (with a fixed direction of illumination) or more complex (to give a certain direction to the light flux).Recently equipped with a turning mechanism, and have another advantage - an additional heat sink area.Therefore, the power light bulbs, allowed for use in rotary fixtures, somewhat larger than for fixed.
Lamps for suspended ceilings can be designed for different light sources, incandescent or halogen bulb.The voltage of power supply can also be different (12 or 220 VAC).
If a halogen lamp, then it usually requires an individual or group down transformer.Its capacity should be selected based on the total load and a certain margin.
