Series SLEX-100 and SLEX-100 HI-LED

Series SLEX-100, REX-100, SLEX-100 HI-LED & REX-100 HI-LED - A compact, explosive-proof light UL- 844 & C-ULC/CSA C22.2 listed to provide lighting and viewing through a single sight port.

• 22% Brighter than 100 Watt Halogen Bulb.
• Uses 93% Less Electricity than 100 Watt Halogen Bulb.
• 35,000 to 40, 000 Hours of Continuous Service.
• Not Effected by Vibration or Shaking (no filament).
• Green Solution - Consumes only 4 Watts.
• Meets Energy Star Requirements.

Explosion-proof, UL-844 and C-UL/CSA C22.2 No. 137 listed, electric lighting fixtures are used in hazardous (classified) locations, lights for single port viewing have been designed to meet the needs of our customers who require lighting and viewing through a single sight glass.

Designated the SLEX-100, REX-100, SLEX-100 HI-LED & REX-100 HI-LED, both models use high-intensity halogen lamps or HI-LED technology to provide bright, glare free illumination of the interior of vessels, tanks, hopper, silos, mixers and other normally closed containers in hazardous locations requiring explosion-proof equipment. The REX-100 & REX-100 HI-LED are provided with a highly polished internal reflector which increases the illumination intensity.

The explosion-proof light can be supplied mounted to the upper flange of our circular sightglass to form a complete light/sightglass assembly. The light fixture can also be mounted to our smaller viewing diameter sight glasses such as 3 1/4" and 4" to form illumination ports. The illumination port used in conjunction with a standard sight glass offers the user many options. A typical option would be the use of a video or TV camera on the free sight glass while the illumination port provides the necessary lighting.

The explosion-proof light fixtures can also be easily mounted to existing sight glasses by means of the slotted brackets provided.

Standard Features:

• The fixture can be relamped without removing the unit from the sight port or distributing any electrical connections.
• Lamp and wiring compartments are separate and are individually explosion-proof per UL-844 and C-UL/CSA C22.2 No. 137.
• Lighting fixture is mounted to outer sightglass flange, completely external to vessel pressure. The fixture can easily be mounted on existing pressure vessel installations by means of brackets provided.
• For corrosion resistance, fixtures are made of copper-free (less than 0.004 copper content) aluminum alloy - No. 356T6.
• Castings have heavy walls to withstand internal explosions without damage. They will also contain and extinguish the flames of burning gases - before they ignite the surrounding atmosphere.
• All metal joints are either threaded or ground. The glass lens is finely ground borosilicate glass that mates with the precisely machined seat in the body of the fixture to form the seal.

The new HI-LED Lighting Series is a high intensity light engine designed to replace halogen technology. The HI-LED is not a standard LED bulb. Custom designed, it offers more robust technology than halogen bulbs. Unlike Halogen bulbs, HI-LED lamps have no filament and are not affected by vibration, impact, heat, dust, or surface oils. Since they do not generate heat, which causes halogen bulbs to burn out prematurely, they may be left on continuously without over heating the fixture housing. The HI-LED provides a bright white light and emits as much or more light intensity (candle power and lumens) as a 100 watt halogen bulb. HI-LED technology offers 40,000 - 50,000 hour lamp life for continuous duty (almost 5 years) versus 1,000 - 2,000 lamp life for halogen. HI-LED lighting is available for both non-hazardous and explosion-proof light fixtures.

High Intensity LED Light Engine Features:

• Not an "Off the shelf led bulb" but a custom designed HI-LED lamp.
• Emits as much or more light intensity (candle power & lumens) as a 100 watt halogen bulb
• Bright white light (High color temp.)
• Does not generate excessive heat.
  - May be left on continuously.
  - Fixture housing does not get too hot.
• More robust technology: HI-LED lamp is not affected by vibration, impact, heat, dust or surface oils.
• Available for both non-hazardous and explosion proof lighting fixtures: Model Numbers: MSL-100, SLEX-100/REX-100 and Select sizes of series PL Light Fixtures
• Retrofit Kits for Model #'s SLEX-100 and REX-100 are also available.
• 40,000 ~ 45,000 hour lamp life for continuous duty (almost 5 years) vs. 1,000 - 2,000 lamp life for halogen.
• Unlike halogen bulbs HI-LED lamps have no filament so vibration and shock will not affect lamp life or cause premature failure. They also do not generate excessive heat which causes halogen lamps to burn out prematurely.
• Longer lamp life = Less cost
  - Save on cost of lamps
  - Save on labor cost to re-lamp: less down-time/nuisance.
