Do you have a high CRI 48" 5000k T8 LED tubes replacement with no PWM flicker?


I am currently looking for replacement 48" 5000k T8 LED tubes for my office. I want something with a high CRI and also no PWM flicker. I see your company has two listings. "CENTRIC DAYLIGHT™ Full Spectrum Flicker-Free T8 LED Tube Light" and "NorthLux™ 95 CRI T8 LED Tube for Art & Studio" Is there a difference between the two? How "Flicker-Free" are they?

Our 5000K high CRI, flicker-free LED tube lights sound like a great fit for your office space!

As mentioned, the two products that have the same part number listing are indeed the same product. They have been listed on separate product pages for marketing purposes, and we do apologize for the confusion caused.

Our T8 lamps do not use PWM as they are not designed to be dimmable. As such, their flicker % is kept to below 2%. (All PWM dimming systems have a 100% flicker rate). In addition to photometric testing, we also periodically perform tests using a smartphone's slow motion video capture mode and can confirm that we do not observe any flashing behaviors associated with non flicker-free lamps.

Also, our test report for T8 LED tube light in 6500K shows the measured flicker values of 2% and a flicker index of 0.00. The electronics of the 5000K are the same and we would expect similar, if not identical, flicker metrics.

One additional factor to consider would be whether or not a fluorescent ballast is installed and used in the current T8 fixture. For our lamps, eliminating the fluorescent ballast can be a sure-fire way to ensure that the ballast is not introducing any extra voltage or current fluctuations that can lead to additional flicker.
