Series MSL — High-Intensity Halogen Illumination for Sightglasses & Sight Flow Indicators
The Series MSL-100 is a UL-1571 listed mini sight light providing high-intensity illumination for sightglasses and sight flow indicators in non-hazardous locations. Manufactured in the USA from Type 304 stainless steel with fully gasketed joints and completely machined external surfaces, the MSL-100 is water tight, dust tight, and ideal for frequent washdowns.
The Series MSL uses a powerful 120V / 100W Tungsten Halogen bulb matched with a conical reflector to provide maximum light output. Rated for 120 volts and 100 watts makes wiring simple and straightforward. An optional 24V version is available in 20W, 50W, and 100W ratings. The HI-LED upgrade version is also available — offering 40,000–45,000 hour lamp life at 93% less energy.
The MSL's clean, compact, all stainless steel design has no fins, threads, or other areas to collect dust, dirt, or bacteria — protecting batch integrity and making cleaning easier. No external power supply or transformer is required.
The Series MSL Sightglass light has been specifically designed for use in the clean areas of pharmaceutical and food and dairy industries. Manufactured in all stainless steel with fully gasketed joints and completely machined external surfaces, the water tight and dust tight Series MSL is ideal for frequent washdowns.
The new HI-LED Series is a high-intensity light engine designed to replace halogen technology. It is not a standard LED bulb — custom designed to save energy, provide uniform light, and extend lamp life to reduce overall operating costs. The LED array has been LM80 tested and is approved for the Energy Star program.
40,000–45,000 Hour Lamp Life
vs. 1,000–2,000 hours for halogen — approximately 4–5 years of continuous duty. Significant savings on lamp costs and labor for frequent halogen changes.
22% More Light Intensity
The HI-LED produces 22% more light intensity (candle power / LUX / lumens) than a standard 100W halogen lamp, at a fraction of the energy.
93% Less Electricity
Operates on 93% less electricity than a 100W halogen lamp — an average yearly savings of 812 kilowatts per year per fixture.
No Excessive Heat
HI-LED technology runs cool and can operate continuously without overheating the fixture housing. No heat transmission into the sightglass or vessel.
Vibration & Impact Resistant
No filament — HI-LED lamps are not affected by vibration, impact, heat, dust, or surface oils. Ideal for pumps, mixers, and mobile equipment.
Uniform Bright White Light
Custom optics provide bright, white, high-intensity uniform light with no hot spots or yellow tint. Ideal for video camera monitoring systems.
