Why Metal Halide and Mercury Lamps Are Being Phased Out and What’s Replacing Them
The February 2027 global move away from mercury/metal halide bulbs marks a turning point for safer, more sustainable illumination

Have you ever had a piece of kit that technically works, as long as you approach it in the right mood, at the right time, and without making any sudden movements? And wouldn’t it be nice to have something that just… behaves?
In fluorescence microscopy, useful illumination is the kind you don’t ever need to think about. And that’s usually the sign it’s doing its job perfectly…
We’re renowned for our incredible tech support and extensive resource library. This blog delves into the questions that are rarely on the spec sheet but are useful in day-to-day microscopy
As the year winds down, a microscope quietly shows us that progress isn’t about one standout component, but about everything working in harmony
In the spirit of frosty mornings, here’s a blog about why LEDs are particularly well-behaved companions even during the chilliest months
Everyone needs a performance review, even Fluorophores, and as with any employee, getting the best out of them is all about understanding what they need…
Fluorophores are a bit like colourful employees working the world’s most demanding shift pattern, who just need a bit of gentle encouragement to get them through their day…
With the ban in Feb 2027 in mind, it’s only fair to give credit where it’s due: Mercury and metal-halide bulbs got fluorescence microscopy this far. LEDs will take it the rest of the way
Whether the work involves basic immune behaviour, developing new immunotherapies or studying inflammation – consistent illumination is one of those quiet but essential ingredients that keeps the data trustworthy
Biology is variable enough. You don’t want the light source adding its own version of “plot twists”. You need consistent, fast, stable illumination every single time
LEDs aren’t only for fluorescence microscopes. They’ve become the preferred light source for lots of inspection and imaging tasks because they’re stable, efficient and easy to control
Need something a little different?
For manufacturers who wish to gain a competitive advantage through bright, stable and controllable illumination, CoolLED’s world-renowned LED technology is available in customised configurations.

Did you know that LED illumination systems help laboratories reduce their carbon footprint, protecting laboratory staff along the way?
Toxic mercury-based microscope illuminators are bad news for the environment, draw a lot of power and have a short lifetime.
LED illumination systems are cleaner, have a long lifetime and use less power. Our pE-300 Series is also ACT label certified and is a natural choice for labs who want to play their part in helping the environment.
At CoolLED we are committed to giving our customers outstanding service right from the start and throughout the lifetime of the product. Please get in touch if you have any questions or would like a quote. You can also browse our site for technical resources and general support.
