This is one o the lamps I'm using on the newly set up 120-gallon reef.
The Blue Plus has LEDs peaking at 420, 450, and 495 nm. The 420nm produces some UV radiation which can excite some fluorescent pigments and of course is absorbed by chlorophylls. Light at 450nm is also utilized in photosynthesis. Peridinin absorbs the aqua radiation and channels it to chlorophylls.
The Seneye device reports Photosynthetically Usable Radiation at 83%.
