The first improvement to light fixtures made by Bell Lighting's Research and Development (R&D) team was simple but radical. Since HID bulbs produce their light on the side of the arc tube, the team decided to design a fixture that would hold the bulb in a horizontal position. This way, 50% of the light would be naturally directed downward - a huge advantage in light delivery. By comparison, the vertically positioned bulb delivers virtually no direct light to the ground.

This simple innovation gave Bell Lighting a huge advantage in light delivery, but was just one of the many improvements set in motion by the R&D department. Several other technological advancements were needed to design and build a near-perfect luminaire.

The next step was to perfect the overall design and configuration of the finished reflector. It had to provide the means to get the remaining 50% of light, developed by a round bulb, delivered to a flat surface. Testing has proven that fixtures built in a round shape are very ineffective at efficiently redirecting light. As a result of their incorrect configurations, a large part of the light developed by the bulb is actually reflected directly back into the bulb rather than to the ground.

All Bell Lighting's units make use of flat panels and proven angles of deflection to maximize on collective, reflective, light delivery. Equally important is the distance between the bulb and the reflective surfaces, for every six inches (fifteen cm) of distance you add between these two, 50% of the light intensity is lost. Bell Lighting has calculated the precise distances and angles for the most effective reflection of light to the ground.

Once the design and configuration of the fixture was perfected, it was necessary to locate the correct fabricating material. This material needed to be completely resistant to rust and corrosion, lightweight, and able to quickly dissipate heat generated by the bulb.

After extensive testing of many materials, both ferrous and non-ferrous, Bell Lighting's R&D team chose ISO 9000, 5052 MARINE ALUMINUM.  It is lightweight, 100% rustproof and able to reflect more heat than it absorbs. Cooler operating temperatures result in longer bulb life.

Finally, the search was on for the ultimate closure material. Our research discovered that even under ideal conditions, the three most commonly used finishes for light fixtures (gloss white paint, polished metal, and chrome) could not reflect any more than 75% of the light produced by the light source. We found these statistics completely unacceptable.

After many hours of research and experimentation, a breakthrough occurred. By making use of one of Mother Nature's base minerals and formulating it into a powder-coating material, we have achieved fantastic light delivery results. Not only does it reflect a consistent 95 to 98% of the light developed by any light source; it's also 100% UV/IR resistant, anti-bacterial, as well as corrosion and acid proof.
