Technical Bulletin: 100 W -T8/BG12 Lamps

August 1, 2004

Our experience in recent months has raised serious concerns over the performance of the 100 Watt Metal Halide T8 G12 based lamps. Due to lamp life performance issues with T8 G12 based 100 Watt Metal Halide lamps we are discontinuing product configurations that require this lamp. We are doing so effective immediately.

Please note that only those product configurations that require the T8/G12 based 100 Watt Metal Halide lamp are affected. Products utilizing other types of 100 Watt Metal Halide Lamps, such as E-17 medium based, or PAR lamps, are not involved.

The major product configurations that will be discontinued include:

1. T100MH version of the Gardco Mantaray. (T39MH and T70MH ARE available.)
2. T100MH version of the CRP22 with Indirect Optics. (T39MH, T70MH and T150MH ARE available.)

We regret any inconvenience these changes may cause. We urge you to utilize one of the
available wattages shown above for these products.

As part of our continuous improvement program we constantly evaluate all lamp options for
Gardco and Emco products. This is just one small aspect of our dedication to maximized
performance and maximized customer value inherent in all Gardco and Emco Lighting
products.
