Yes. I am always trying different spacing and coverages, so all my builds are a "test." But, tape is all I have used. I must say using Kapton tape on white or silver sheet metal looks a little ghetto, but it works great. You don't need any thermal grease. Clear tape, like you have, should work great. Just check the strips from time to time to see if the strips are still flat and snug against the heatsink.
As an aside, my original LED DIY build using long finned extruded heatsinks and Vero 29s, well the COBS were installed with Kapton tape. And 3 years later, still working great. I credit Supra for the Kapton tape mounting idea.

The real test to see if you are dissipating enough heat using your tape mounted strips is to check voltage droop on your strips.
BTW, cobs do need thermal grease, strips do not.

That Scotch mounting tape will work, but I don't think it will conduct heat well. I use this thermally conductive tape...

Op's tape would probably melt a bit and you'd be dropping lights soon after
thermal adhesive ftw, but be careful applying because it is a strong bond that is tough to undo without some practice.

The Scotch mounting tape only holds the strip to the sink. The back of the strip is in full contact with the heatsink. I am running EB ver. 1 strips at 75% of max. (1.05a) and it works great. About 1.5% voltage droop max.

Im talking single sided. You are right for double sided. That goes between the strip and the sink.

Like others have said, don't use the tape you showed a picture of. You need double sided thermal tape. It's cheap and works great. I have a fixture that has 6 1120mm strips held only by the cheap double sided tape and they are on there really good. Infact, I had to use a putty knife to get one or two off.
