Ocean Insight offers sturdy, reliable tungsten halogen light sources to meet your application requirements. From high-power to long-lifetime models, our HL-2000 product family provides flexibility for your lab for measurements from 360-2400 nm.

All HL-2000 models have an integrated fan to keep source cool and stable, and a built-in holder that accommodates filters for conditioning the light. Some models include an integrated shutter and long-lifetime bulb. A universal power supply makes setup quick and easy.



  • Visible-NIR wavelengths -- sources provide output from 360-2400 nm
  • Fiber optic -- maximize light throughput with adjustable focus and alignment of the SMA 905 connector
  • Standard and enhanced models -- optional configurations offer high power or long lamp lifetime
