The primary consideration for the design of lighting fixtures regarding combustible materials is temperature management. Proper temperature management is crucial because lighting fixtures, particularly those that produce significant heat (like incandescent and certain types of halogen lights), can pose fire hazards if they come into contact with combustible materials.

Designers must ensure that fixtures maintain appropriate operating temperatures to prevent any potential ignition of surrounding materials. This involves using appropriate heat-dissipating designs, such as heat sinks or proper ventilation, and selecting materials that can withstand the heat produced by the light source without degrading or melting.

While electrical efficiency, material cost, and color temperature are important factors in lighting design, they do not primarily address the risk of fire hazards associated with the overheating of fixtures. Thus, temperature management stands out as the most critical consideration for ensuring safety when dealing with combustible materials.
