I tested most of these a year or two ago.
My purpose for testing these was to find the best lights for use in my home. I like warm lights with negative DUV (below the BBL or rosy tint) with very little blue light to minimize suppression of melatonin. My favorite so far is the Auxma 2400K led strips with the SMD2835 due to their perfect warm cozy rosy tint and very low blue light content. Overall, I’ve been very surprised how high the light quality is in almost all of these Aliexpress/Alibaba lights I’ve tried. Compared to the dozen or so different led strips I bought from Amazon 5-6 years ago that tested 60-70CRI with positive DUV (green tint), these are in a whole nother league. I just wish high powered LED for flashlights will match these in light quality in the near future.

I ordered a new batch of Auxmer (formerly Auxma) LED strips to test. My all time favorite was their 2400k. Seems the quality haven't changed after two or more years. They recently released the 2200k, which is also amazing. The 2000k is like candle light and perfect for the bedroom as it produces negligible amount of blue light, which means it is the best for sleep.

Hey SKV89, very interesting, thanks for sharing all these test results! What test equipment did you use for all these measurements? I'm familiar with CCT, CRI/Ra and R9, but what are DUV, Rf, Rg and blue peak? A link to some "extended basics" :shrug: is very welcome :D

I'm also currently looking for LED strips to light my living room. I personally prefer cooler type of light, more like natural daylight, but for the sake of being able to create a cozy atmosphere at night with others, I will go for tunable white so that I can adjust CCT also to warmer tones.

You wrote about the Gree Lamps and Components 2835 108 led/m DC24V 2500K "R9: -3.3". Can this negative value be correct???
