The Zircon Warm Amber filters correct and warm up a range of different Color temperature white LED's. Longer life filter for correction of warm white LED. (Example: 3500K LED to 3000K)Less ThanBRGreater ThanNote: Color Temperature shift varies with type of LED.Less ThanbRGreater ThanLess ThanbRGreater ThanZircon FiltersA new concept in LED filter design.Less ThanbRGreater ThanLess ThanbRGreater ThanFine-tune your LEDsLess ThanbRGreater ThanThere's a reason why lighting designers are turning to Lee Filters 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.Less ThanbRGreater ThanLonger Life Filters for LEDLess ThanbRGreater ThanLED lighting has many benefits, but one of its stumbling blocks is that its intensity can contribute to the fade times of standard lighting filters.Less ThanbRGreater ThanLess ThanbRGreater ThanIn order to overcome this, the Lee Filters Research and Development team has developed a new way of producing filters that ensures they last longer when used with LED lights.Less ThanbRGreater ThanLess ThanbRGreater ThanIn 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 SubstrateLess ThanbRGreater ThanNot only are Zircon filters longer-lasting than their standard counterparts, t
