Luminaires (Non-Ex)

Product Picture: Lumistar Luminaire USL 16 and USL 36, stainless stee

Also available in LED technology

Fully Sealed Lumistar Sight Glass Luminaire with cover glass compact, all stainless steel

  • USL 16: for general applications, mounted with hinged bracket
  • USL 36: special variant for sterile environments with adapter collar
    for fitting over flanges, etc.

The perfect combination of flush contours and smooth surface:

This sight glass luminaire is designed for universal applications. It is ideal for use in combined sight and light ports (single-flange version) or for two separate ports (2-flange version).

Ultra-bright LED provides 3000 lumens

Compact design, powerful light output:

Glare-free illumination; suitable for circular sight glass fittings to DIN 28120/DIN 28121 or similar, for screw-type sight glass fittings in compliance with DIN 11851, and for METAGLAS® and BioControl fittings.

Application in chemical, pharmaceutical, biogas and food processing  industries:

It is ideal for illuminating bioreactors, laboratory mixers and filters as well as the interiors of tanks, agitators, separators, pipelines and other, usually closed, vessels in non-explosive operating environments.

Protection class: Dust- and waterjet proof, IP 65 according to EN 60 529 / DIN VDE 0470, Part 1

Suits all Lumiglas Sight Glass Fittings from size DN 40
Operating voltage/power: 24 V, 120 V, 230 V / 20 W, 50 W, 100 W, with transformer 230 V /20 W
Secured by hinged bracket or adapter flange

Max. admissible ambient temperature at the cable entry gland with halogen version: 90°C; with LED version: 40°C.

This LIGHT is the world’s brightest sight glass luminaire:  LED luminaire is four times brighter than a typical sight glass light, offering an unprecedented view of processes.  Ultra-bright LED provides 3000 lumens at full brightness, four times the light output than a typical 100-Watt halogen light.  The total internal reflection (TIR) lens with 23-degree beam angle, is ideal for vessel illumination through a sight glass with maximum light output and less than 5% loss of light output.  The light is capable of continuous operation and emits cool white, 5500K color temperature, optimized for stainless steel vessels.  The light is designed for cool operation equipped with temperature-based current limiting and automatic dimming; over temperature shutdown.  The LEDs have a long service life and are vibration and impact resistant.  No heat radiation is directed into the process vessel (cold light output).   The housing is available with a mounting bracket (USL16 Light) or a sanitary clamp connection (USL36 Light)

Lumiglas® Luminaires

Luminaires illuminate process vessel interiors in pharmaceutical, food processing, and chemical plants.

Choose from standard Luminaires (Non-Ex) and explosion-proof Luminaires (Ex) housings as well as halogen or LED designs.

Some applications require safe, high-intensity illumination for sight glasses, ports, or general applications in hazardous (classified) locations.

Lumiglas luminaires are available with aluminum or stainless steel construction and, depending on the size and wattage, can be equipped with momentary push button switches for safety and longevity. Remote or pneumatic timers and pushbutton switches are also available as Lumiglas light accessories. A new series of  Lumiglas LED Luminaires is now available.

In short, the luminaire is the entire device and the lamp is the specific replaceable component that produces light.

“A lamp is a light source that is placed in a luminaire!”

A light fixture (US English), light fitting (UK English), or luminaire is an electrical device used to create artificial light by use of an electric lamp. All light fixtures have a fixture body and a light socket to hold the lamp and allow for its replacement.

Sight Glass Lights

There are many considerations for selecting the optimum light to illuminate your process vessel. This online guide walks you through the steps.

Dedicated or Separate Light Port

Often process vessels have two sight glass windows: one port for viewing and a separate port for the light. The light is typically mounted directly over the light port. To save cost or space, some vessels combine light and sight at one window. The light is typically mounted with a bracket, although sight glasses are available with integrated lights (combo style). 

LED or Halogen

Traditional halogen lights use trusted incandescent light bulbs. LED lights offer brighter light, lower energy consumption, and longer life (lower maintenance costs.) Halogen light brightness is selected by wattage: 5 to 100 Watts, with 50 Watts typical. LED light brightness is selected by lumens: 1000 to 3000 lumens.

Explosion Proof or Non-Explosion Proof

Some industrial environments require explosion proof lights (ex lights) that are sealed so they cannot introduce a spark into the atmosphere. The widest selection of ex lights are halogen style, although explosion proof LED lights are also available.

Stainless Steel or Aluminum Housing

Virtually all sight glass lights use stainless steel housings. A few ex light models are available with aluminum housing, lowering their cost while removing heat more efficiently.

Available Power Supply

Most lights are available in a range of voltage options. Make sure that the model you select will work with the power you have available: 120 VAC, 24 VDC/VAC, 230 VAC, 12 VDC/VAC.
 
When deciding upon a proper luminaire for your application, be sure to consider all of the properties of the light. The size, weight, voltage, wattage, materials of construction, mounting configuration, and light pattern (Lux diagram) are all very important factors you should be aware of.
