Fine-tune your LEDs

There’s a reason why lighting designers are turning to our Zircon filters for their LEDs. It’s because they’ve been specifically designed to fine-tune the inconsistencies often associated with LED lighting, ensuring your LEDs give the same performance, time and time again.

Warm Cool Diffusion Correction

Longer Life Filters for LED

LED lighting has many benefits, but one of its stumbling blocks is that its intensity can contribute to the fade times of standard lighting filters.

In order to overcome this our Research and Development team has developed a new way of producing filters that ensures they last longer when used with LED lights.

In fact, Zircon Warm Amber filters have been shown to retain at least 80% of their effectiveness after as much as eight months of continuous use on LED downlighters.

Heavyweight Substrate

Not only are Zircon filters longer-lasting than their standard counterparts, they’re sturdier, too.

Manufactured using a 180-micron material, they are more than double the thickness of a normal lighting filter. This makes them more durable and easy-to-use.
