RoHS Program

In recent years, there are increasing concerns for environmental conservation globally. The Directive 2002/95/EC on the Restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS) was issued in February 2003. The RoHS directive restricts the use of the following substances on products sold into European markets from July 1, 2006:

  • Lead
  • Mercury
  • Cadmium
  • Hexavalent Chromium
  • Polybrominated Biphenyls (PBB)
  • Polybrominated Diphenyl Ethers (PBDE)

Light Sources Products:

All of our products are now fully compliant.

Light Measurement Systems Products:

Because our products are used as measurement devices there is an exemption on RoHS compliance. However, we are developing all our new products to be compliant and retro designing our older products when resources are available. We expect to have all our products fully compliant in the next few years.

If you have a question or a concern about a certain product please contact our RoHS Department for status on that product. More information on RoHS is available from the official RoHS website.
