logoWest Coast Growers offers lighting systems and accessories by Bell Lighting Technologies Inc. (BLT Inc.).  Products by BLT Inc. are fully compatible with West Coast Grower's GROW-Stands and Hood hangers. We have chosen BLT Inc. systems because they offer the widest variety of lamp configurations, as well as the most competitive warranties.

by using Bell Lighting Reflectors

   Distributed by West Coast Growers, these industrial grade reflectors are manufactured from light weight 5052 marine aluminum that is rust proof and completely welded for superior structural strength.
   These reflector panels have the highest PAR value in the industry and are specifically proportioned in such a way that 45% of the light is direct while 55% of the light is delivered through deflection. Each reflector panel is proportionately sized to lamp geometry in order to precisely optimize reflectivity. This  is why the reflectors come in different sizes.
   Many reflectors use inserts to optimize reflectivity but inserts often times degrade rapidly with use. This costs by robbing valuable lumens and wasted electricity over time.  Bell Lighting Technology has addressed this problem with their own patented powder coating material.  The powder coating is 100% resistant to UV/IR discoloration which is why a 30 year warranty is provided with every reflector sold! This means you can be assured you are getting 95 to 98% of the source lighting consistently over the lifespan of the reflector.
   This special coating is corrosion and acid proof with anti-bacterial qualities as well.

    Inserts create another problem when it comes to effective lamp cooling. Most inserts inhibit air flow through the reflector and do not effectively cool the lamp requiring larger fans to over come conductive and thermal loading. The MV series reflectors are mechanically ventilated and do not require inserts resulting in efficient cooling of the lamp. The 5052 Marine aluminum also comes into play here because it has characteristics which allow it to  reflect more heat than it absorbs.

   The MV series reflectors require 10 to 15 CFM to keep them running cool. Each MV kit comes with 4 inch tap-in collars for ducting and a glass trim kit for mounting of the lens.

MV series: add $28.95 for 1000 watt glass and $25.95 for 600 watt glass.

  West Coast Growers does not guaranty glass from breakage during shipping. Please consider buying your TEMPERED GLASS from a local vendor to save cost.

How does Bell Lighting compare to the rest?

An independent controlled test carried out by the University of British Columbia Department of Agriculture was conducted to compare the yield of bell peppers grown under lights manufactured by P.L. Lighting Systems and Bell Lighting fixtures.

Summary of results (view full report below for details)

    • P.L. 400W HPS light:
      • Produced 1 bell pepper per plant approx. 1.5” diameter
      • Weak plants, sparse foliage
    • BELL LF 400W HPS fixture
      • Produced 4-5 bell peppers per plant approx. 3.5” diameter
      • Healthy, strong plants.

  • (Note: The BLL LF 250W fixtures, in equal numbers to the P.L. 400W fixtures, produced the same yield as the P.L. fixtures while consuming 37.5% less energy)

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.
