No, but I have looked at Sunmaster literature and it is a combination of lies and nonsense. First, I call your attention to

1. Their photosynthetic action curve is a lie. The true photosynthetic action curve depends on the plant species. In the paper, Action Spectra for Photosynthesis in Higher Plants, the action spectra for 33 different plants were determined. See

and observe that

A. the maximum for almost all plants occurs near 660 nm, not 630 nm as indicated by Sunmaster.

B. At 400 nm, the relative efficiency for most plants is less than 0.25 whereas the Sunmaster literature shows 0.5.

C. The curves agree that a relative minimum occurs near 470 nm, which is blue-cyan and not green as commonly believed.

D. The curves agree that a minor peak occurs near 435 nm and not 450 nm as commonly believed.

Now, I call you attention to the Power Spectral Density of the bulb and the table:

E. Most of the bulb's light is occurs near 550 nm which strongly suggests that the bulb was designed for human vision and marketed for plants as an afterthought. There is little justification for green light in grow lights.
