Distribution Channels

The SLS4-10LED (Single sided / Double sided) emergency exit sign can be recessed mounted, surface wall mounted and ceiling mounted. The LEDs used for illumination are SMD low Power High Lumen type. Its uses SMT technology that consumes 6 times less electricity than those using fluorescent bulbs with 7 times longer operational life, the quality and brightness of illumination is also certified by the Thai industrial Standard 2430-2552 and Thailand Engineering Standard 021004-18. The device is controlled by the microcontroller. Thus, it can be activated by either pressing the Function Test button on the device or by remote testing. The sign is made with clear acrylic sheet that evenly diffuse the light throughout the whole sign, even after an extended period of use. The chassis is made with 1 mm. thick Electro-Galvanized sheets coated with Epoxy powder and stove enameled to help protect from any possible rust.
