The old paradigm was to think about flashlights as either metal lights or plastic lights.  Today, that view is far too simplistic as we have many lights that use several discrete materials, composite materials and hybrid materials. These materials inclulde:

  • Aluminum:  Typically strong, lightweight, durable and more expensive than ‘plastics’.
  • Polypropylene:  Reasonable impact resistant, excellent chemical resistance, light weight, tough.
  • Polyethylene:  Superior chemical resistance, tough, readily molded or extruded, very low cost, difficult to bond or print on.
  • ABS – Acrylonitrile Butadiene Styrene:  High impact, durable, heat & chemical resistant, easy to process & fabricate & finish into complex forms.
  • Epoxy Glass: High strength-to-weight ratio, non-conductive.
  • Injection Molded Magnesium:Injection molded so can incorporate complex shapes and forms with a metal light.
  • High strength to weight ratio
  • Heat dissipation similar to aluminum.
  • Higher stiffness than plastics.
  • Thinner wall sections.

Energizer uses high-quality magnesium alloys, aircraft-grade aluminum and advanced polymers (ABS plastic, polycarbonate and epoxy glass) in the design and construction of our most durable casings. These super-strong materials make Energizer® lights highly resistant to damage from impact and allow us to engineer lights with smaller footprints and lighter weights without sacrificing strength. Waterproof and water resistant seals help our lights stand up to the elements.

Additionally, with the significant amount of light produced by LEDs, heat management is instrumental in realizing the maximum benefits of this light source. Energizer addresses this need to reduce heat with advanced patent-pending cooling fins built into the magnesium alloy casings for efficient heat dispersion.
