Starting the conversation early makes things easier. One of the advantages of knowing about the phase-out ahead of time is that it gives labs space to think about their options calmly.
Very few facilities actively and accurately track their mercury or metal halide bulb usage over time. They get ordered, installed, replaced, and eventually forgotten about. But this creates a blind spot…
Optogenetics is all about precise control: the right wavelength, the right intensity, the right timing. The pE-300opto is built to deliver exactly that, offering just the wavelengths and control that matter, in a compact, affordable package.
We recently attended EBP South’s ‘Get Inspired’ event, where Marina, Alex and Andrew spent a busy day speaking with young people about careers in STEM
Have you ever felt like your microscope has a slight vendetta against you? It seems to works okay for everyone else, but for you it’s like trying to convince a really tired toddler to put their shoes on? Chances are, it might not be your fault…
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
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.
