The total wattage maybe enough. 72 watts on your 40 gal breeder but the spectrum is not. Over the last 10 years or so LED advances a lot. Mainly we find that the actual spectrum of the light is important. These lights are too narrow in spectrum. The graph that they provide is really misleading. LED especially these light do not have those spectrograph. Most of the effective light, even Chinese ones are full spectrum light with multiple color em miter that mixed to form the color seen.
The strip you have is not good for coral or clams growth, IMO. I never used them so I do not have first hand experiences with them
