The TecNec FSL-4 is a large warning light with a bright red glow and a white 3-sided shell. Its ultra-high impact housing can be easily mounted on any surface. It runs on AC power, making it suitable for both outdoor and indoor use. The recommended installation is to hardwire it to a 110v junction box. Key features include ceiling or wall mounting (9.25'H x 6.375'W x 4.75'D overall), a 16-gauge cold rolled steel baseplate, a one-piece UV-stabilized polycarbonate lens, a breakage guarantee, a 120V 75W incandescent wall fixture, and a medium base socket (standard incandescent). Technical specs show a one-piece wraparound lens/housing of UV-stabilized, high impact polycarbonate with a high efficiency pearlescent lens. The baseplate is 16-gauge CRS with a white TGIC polyester powder coat, passing a 1,000-hour salt spray test. It has a die-cut closed cell neoprene gasket, two stainless steel Torx fasteners, a medium base shock absorbing lamp socket. It must be installed lamp base up and standard four-point mounting is required for the guarantee. It's UL and CUL listed for wet locations. Mount plate dimensions are 8.75'H x 5.75'W, and overall light dimensions are 9.25'H x 6.375'W x 4.75'D.
Using the TecNec FSL-4 warning light is straightforward. First, find a suitable location, either on the ceiling or the wall. Make sure the surface is flat and can support the light's weight. Then, hardwire it to a 110v junction box as recommended. When installing, ensure the lamp base is facing up and use the standard four - point mounting method to keep the breakage guarantee valid. This light can be used both indoors and outdoors because it runs on AC power. Just remember, it's UL and CUL listed for wet locations, so it can handle some moisture but don't submerge it. For maintenance, check the lamp regularly. If the light seems dim, it might be time to replace the 120V 75W incandescent bulb in the medium base socket. Keep the lens clean with a soft, dry cloth to maintain its bright red glow. Also, periodically check the fasteners to make sure they're tight and the gasket is sealing properly to prevent any water or dust from getting inside.
