Natural Dimming

No flicker*

Flicker, who cares?  If you're specifying LED lighting, yóu should!


Both visible and non-visible flicker can be the cause of an entire array of performance and health effects, ranging from eyestrain to serious neurological problems such as epileptic seizures.


eldoLED believes the IEEE P1789 standard and the diagram associated with it are great tools to compare drivers with regard to flicker. We suggest the following recommended practice for the specification of LED drivers:


"LED drivers shall conform to IEEE P1789 standards. Alternatively, manufacturers must demonstrate conformance with product literature and testing which demonstrates this performance. Submit % flicker in 1% increments for full range of dimming starting at 500 mA for full output reading. Systems that do not meet IEEE P1789 will not be considered."


*All eldoLED constant current drivers meet the IEEE P1789 recommendations.
