No More Mercury: The Fluorescence Microscopy Bulb Ban is Coming

Mercury bulbs have lit up labs for decades, but their time is nearly over.
From February 2027, the use of bulbs that include mercury (including metal halide and xenon??) in labs and facilities worldwide will no longer be permitted.

Mercury is toxic and hazardous to dispose of

Bulbs are becoming harder (and more expensive) to source

By February 2027, they will be completely phased out

👉 The clock is ticking. Now is the time to future-proof your lab.

No more mercury timeline

Why Switch to CoolLED?

Going mercury-free isn’t just about compliance. It’s about sustainability and smarter science.

  • ACT Label certified (pE-300 and pE-400 Series)
    The ACT Label (Accountability, Consistency, Transparency) is often described as a “nutrition label for lab equipment.” It is managed by My Green Lab and independently verified by a third party. Products are scored on manufacturing, energy and water use, packaging, end-of-life disposal, and corporate responsibility. Achieving certification shows that CoolLED products meet strict environmental standards across their full lifecycle.

  • EcoVadis Bronze certified
    EcoVadis provides one of the world’s most trusted business sustainability ratings. Companies are assessed across four themes: Environment, Labour & Human Rights, Ethics, and Sustainable Procurement. Earning a Bronze medal places CoolLED in the top 35% of companies assessed worldwide, recognising our ongoing efforts to improve environmental and social responsibility across our entire business.

  • Nearly 2 decades of innovation in LED Illumination
    We’ve been pioneering mercury-free LED Illumination since 2006 – reducing energy use, cutting waste, and eliminating hazardous materials.

What this means for your facility:

  • Lower energy consumption and substantial savings in running costs

  • Safer disposal with no hazardous mercury waste

  • Reduced heat output, protecting samples and extending microscope life

  • Easy compliance with sustainability audits and reporting

  • Confidence that your supplier is independently verified for environmental and ethical responsibility

By switching, you’ll not only remove mercury from your lab, but also support wider global sustainability goals.
