I didn't really look, just popped up when browsing. I just think the 165w vispar are too heavy on the white channel. Wish they still had the 300w panels, they were heavier on the blue.I saw that as well, but the spectrum is kind of trash.
Vipar is 1:1:1 420, 450, 470.
The philzon is like 1:12 410, 470
