Aluminium and Iron in Decorative Lighting Bodies
Almost every fixture in this catalogue is described as aluminium plus iron. This explains what each metal is doing and why the combination is not a cost compromise.

Aluminium Carries the Heat
The LED board sits against the aluminium body. Aluminium conducts heat away from the diodes, and diode life is largely a function of junction temperature. A decorative fixture with a plastic body and no metal path runs hotter and ages faster.
Iron Carries the Load
Suspension brackets, canopies and mounting plates are iron. Iron is stiffer than aluminium at the same section, so the parts that take the hanging load are iron while the parts that carry heat and take the finish are aluminium.

The Finish Sits on the Aluminium
Sand black, matt white, matt gold, rose gold and chrome are all applied to the aluminium body. This is why we ask buyers to order matching pieces together: the spray batch, not the model code, is what makes two painted fixtures match.

Weight Tells You What Is Inside
We publish product weight on most models for this reason. A 900 x 900 mm ceiling fixture at 2 kg is an aluminium and iron build. The same size at half that weight is mostly plastic.

Questions On This Topic
Why not make the whole fixture from aluminium?
Iron is stiffer at the same section, so the suspension and mounting parts are iron while the body that carries heat and takes the finish is aluminium.
Does the metal body affect LED life?
Yes. Diode life depends heavily on junction temperature, and the aluminium body is the heat path away from the board.
How do I check what a fixture is actually made of?
Compare the published weight against the size. We list product weight on most models.
