LED Strip lighting

I’m not committed to SB-LED, but I’ve always gotten exactly what I’ve ordered from them and they provide the most specs up front. I’ve seen on the other major thread on LED strip lights that no matter what the seller says the quality and specs are completely unknown when you order from China. That doesn’t bother me on $10 flashlights, but this is something that has to get spousal approval. I did a quick aliexpress check and see LED strips for less than $10, or about $30 if I include “High CRI” in the search. The High CRI, high brightness SB-LEDs strip is over $140, and $60 for the one that is 20% as bright , but still High CRI.

Is the American shipping markup 400% - 600%? Are the Chinese ones going to be radically different specs?

How is the brightness on yours? My concern is that since I’m replacing fluorescents I want something to be about as bright. For example one cabinet has a 3’ T12 (2350 lumens according to Philips). Using the brightest single LED strip at SB-Led at 511 lumens/ft is 1500 lumens, in the same ballpark. Using the numbers on one of the AliExpress sellers of 100 lumens/ft means I would only get 300 lumens in that space, and those are Chinese lumens so it could be even less. I can’t suffer the embarrassment of “Is it on yet?”

I wish I knew who the Convoy of LED Strips was: a reliable seller, accurate specs, good quality, not the lowest price but best for the quality.
