Not only do they have more than one series that use different leds on the M Samsung series (maybe the others too) they are available in different amounts of LEDs per foot.
Since I want lower output but better spread for seedlings I got the weakest ones in the M series.
If I was building something like @brahbbyB or a veg light i would get the strips with the highest density.

the listed used wattage is off, but i guess at the end of the day, it doesn't really matter. i can get wattage as long as i know the wattage of the driver and how many leds im using.

Hooked up a 4" flexible exhaust and inline fan (~65CFM from HD) out the top of tent. I opened the bottom vent on the tent. Temps look like they lowered ~6 degrees. Air temp staying constant ~24C/75F.
49C: Backside of LED #6 in center of fixture.
44C: Top of 1x1" aluminum rail on long side.
24C: Ambient Air (hanging ~2 feet below lights).

Keeping the backside of the heatsink (20 ga sheet) under 50C, canopy temps under lights about 75F, and over 800ppfd (36 cobs watts a square foot)...that ought to grow some serious weed!

These might work but not sure of LED spacing:

same here, waiting on some emails....will report back, please do likewise if you hear/see anything else
Got around to soldering my Far Red XP-E's onto my sample PCB's. Been looking for an excuse to try out toaster oven soldering. Used the end of tube of tin-lead dispensable paste I was able to rescue from being tossed at work. Tested one of the 6up strings all the way up to the max 1000ma drawing right around ~15W.
Plan on mounting these in the center 1/3 of the way from the edge and running for 5-10 minutes after lights off. I will hopefully have them mounted and wired tomorrow night.

I will do a blog post or something. Digikey bless their hearts, are ferkin morans...seriously. And the only reason I bring this up, is because they decided to up my shipping 400%. The packaging was maybe worse than bending them....They were entirely loose in the biggest Anti static bag I have received to date
and were just banging around each other or in piles. Wtf over, entirely defeats the purpose of the anti static bag.....I am thinking I got the 1st one in the morning, packaging job. Which had so much unneccesary stuffing i.e. weight, when it really is a lenghth penalty [my reason for the increased shipping AFTER using the "estimated shipping"]They have always been my favorite and I have always had A+ service.....but this one had me on the phone....Im kinda pissed and entirely has nothing to do with Bridgelux....get your shot together Digikey for r3al.

What temp sensors are you using? Do you have a link?
