Frequently Asked Questions
How do lighting kits differ from general ones?
The fitting has to be levelled and it has to look right.
Visual alignment is a real requirement rather than a refinement.
One pendant hanging a few millimetres low is immediately obvious.
A misaligned pipe support never is.
Adjusting at the bottom by hand is what makes it practical.
Levelling after installation rather than measuring beforehand is the whole workflow.
How many suspension points does a luminaire need?
Most linear fittings need two to hang level.
A single point lets the fitting tilt.
Two points fix the attitude properly.
Levelling then becomes a matter of matching the drops.
Longer fittings sometimes need more.
The luminaire manufacturer generally specifies the suspension points.
What about the supply cable?
It has to reach the fitting, and how it does so affects appearance considerably.
Kits with a cable route through or alongside the suspension keep it clean.
A supply cable looping separately spoils the effect.
That effect is what the suspension was chosen for.
Some kits carry the supply within the suspension itself.
Planning the cable route before installing avoids an untidy result.
Is weight a concern?
Less than for services, but the anchor is still the limit.
Luminaires are light compared with pipework or duct.
Suspension into a ceiling grid or plasterboard soffit is limited by the structure.
Lightweight decks hold very little.
A fitting may be replaced by a heavier one later.
Specifying the anchor for more than the current fitting is sensible.
Can a run be levelled after hanging?
That is precisely what these kits are for.
The gripper locks anywhere along the cable.
A release lever allows the drop to be adjusted.
A whole run can be levelled by eye after installation.
Excess cable is cut off afterwards.
That is far quicker than calculating each drop in advance.
Do emergency fittings need anything extra?
In some jurisdictions, yes.
Services forming part of a fire strategy may carry additional support requirements.
Emergency lighting is frequently covered specifically.
Supports may need to survive a stated fire exposure.
Requirements differ substantially between markets.
The local regulation governs rather than the suspension manufacturer's data.
Is bracing needed?
Where seismic provisions apply, suspended fittings need bracing against sway.
Wire suspension resists gravity rather than lateral movement.
A pendant fitting swings freely without restraint.
Bracing components are specified separately from the suspension kit.
Requirements vary considerably between regions.
In non-seismic areas swaying is usually an appearance rather than a safety concern.
