LumiStar® 3000

LumiStar® 3000 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 24-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)

Fits the following nominal sizes:

  • Circular Weld-On Sight Glass fitting to DIN 28120: from Size DN 50 (3” view diameter)
  • Circular ANSI Bolt-On Sight window: from size 2”
  • Visual Flow Indicators: from size 2”
  • Circular Weld-Neck Sight Glass fitting series MV: from DN 50
  • Sanitary Clamp Connection Series MetaClamp: from 1”

Protection:

  • Dust and waterjet tight to IP 65 to DIN EN 60529/DIN VDE 0470 Part 1
  • Dust and Waterjet tight to NEMA 4X

Operating conditions:

Independent of internal pressure/vacuum in the vessel, standard LumiStar3000 luminaires are approved for use in ambient temperatures from -40ºC up to +80ºC at the cable entry gland. Under no circumstances should these luminaires be used for sealing vessel openings – an appropriate sight glass fitting must be used at all times.

Operating voltage:

  • Low Voltage: 24V (AC or DC)
  • High Voltage: 110-240V AC
