PRODUCT REVIEW
Ultra High 95 CRI T8 LED Tube for Home & Office
★★★★★
Great Quality of Light...but...flickers.
I ordered the 4000k T8 tubes to replace the fluorescent lights in my kitchen. The quality of light they produce is stellar. No green tinge, great rendering of reds; a very well balanced neutral white light. My only problem with them is that they flicker. Without a ballast, or with a magnetic ballast, the flicker is intolerable and clearly visible. Even with a high frequency electronic ballast, the lights flicker at the ballast frequency. A photosensor and an oscilloscope clearly show it. Some may say that this is of no concern, as the flicker frequency is too high for humans to perceive. But, as a life-long sufferer of migraines, nausea, and eye pain due to flickering light sources, I'd much prefer to know that the interior lighting in my home is truly flicker-free. I'm on the fence as to whether to keep them or return them. Flicker-free T8 options are available from other sources, but I am certain that the quality of light will not be as high. I wish I didn't have to choose between high R1 through R15 values or flicker. Why can't these tubes be designed to be flicker-free, as are some of the A19 and strip sources you offer?"
