Marketing Claim Verified by UL

Low Optical Flicker Less Than 5% Up to 1000 Hz

Verification Method

The LED luminaire has a control gear that can provide dimming. For the purpose of the Low Optical Flicker verification program, the following tests were conducted at the specified dimming levels: 100% Light Output, 20% Light Output and 10% Light Output. The corresponding waveform at each dimming level was captured via oscilloscope coupled to transimpedance amplifier and integrating sphere system.
