"The light from the LEDs would be directed to the inside of the letter. This would cause the light to bounce around inside of the letter before exiting the polycarbonate back. With the new wider projection LEDs, we now attach the LEDs to the back of the letter face and let the LED shine directly back to the wall. The halo is brighter this way and we don't have to worry about hot spots." Avoiding hot spots seem to always be a concern with channel letter projects. In many cases, the initial design and production of the project can eliminate these issues. Careful planning will go a long way. "Installation of the letters should be thought out well in advance of the actual day of the install when selling halo-lit letters or any other type of sign," says Wheeler. And a significant part of the process is finding the right complement to the letters and lighting. "Sign makers should avoid glossy backgrounds, because you will see every module in the reflection and will not get an even light output," says Parks. "Matte finished or masonry walls like stucco, brick, or rock are perfect for a halo-lit project." Flaska concurs saying, "One of the most common mistakes is installing halo- lit letters on the wrong wall or substrate. For proper halo lighting and to avoid seeing the points of light, halo-lit letters should be installed on a matte surface. The more reflective the surface the more the LEDs and even installation hardware will tend to be seen." Installing the components can some- times take more effort than first cal- culated. It is important to have all the information upfront so that the work is not held up during the install. "During the initial site survey, one should establish the way the sign is to be installed," suggests Wheeler. "In many cases halo-lit letters will require sheetrock to be removed from inside the building. While installing, never put any type of wire splices in the wall. The wires should be long enough to reach the power supply or an area where they can be accessed easily." For sign makers who provide chan- nel letter projects, it's wise to become acquainted with all offerings—includ- ing halo-lit. There will likely come an instance when a client asks about it; and you will be prepared to extend profes- sional support. SDG Halo lit signs stand out due to the sharp contrast of the bright backlighting with the dark channel letters at night.
