Microscope Illumination From Prior Shows A Whole New Light

Prior UK has over twenty years of experience in illumination; the new Lumens 200 microscope illumination range is a prime example of how Prior’s expertise in the field puts things in a whole new light. This is the most versatile, powerful and cost effective illuminator available today.

Both illuminators feature a 200 Watt metal halide arc lamp with an industry leading 2,000 hour life. They’re incredibly easy to use and maintain, with low heat transfer to minimize thermal drift, easy to replace bulbs and constant microscope illumination with their stabilized DC power supplies. They’re illumination systems ideal for the lab which outperform 100 watt halogen and mercury lamps in every category at a low cost.

The Lumens 200 and Lumens 200 Pro provide light with a similar spectral output to older mercury vapor lamps, but with a much longer life, making them perfect microscope illumination solutions for any laboratory where reliability and flexibility are vital concerns.

Manual shutter operation and attenuation, remote mounting with a two or three meter liquid light guide allow these illuminators to provide high performance and unbeatable flexibility in the lab – adjustments take less than a minute!

Features of the Lumens 200 and Lumens 200 Pro Illuminators include:

  • Quiet operation suitable for laboratory use
  • Easy to view display screen for bulb life indication and alarm description
  • Secure light guide installation with knurled light guide clamping knob
  • Adapters available for all modern research microscopes
  • Six position adjustable aperture/intensity knob prevents photobleaching


Lumens 200 and 200 Pro microscope illumination systems monitor usage electronically and warn the operator with a visual and audio alarm when bulb replacement is necessary.
