it is a blue LED covered with a phosphorous layer. This Picture show a typical spectra for a low Kelvin White LED
My max settings is 80 % of amber, cyan and 100 % of the other in this matrix

i have cheap fluval marine and sea on my 29 gal standard. this thread had me thinking that while it has blue and red leds, it's dominated by white leds and if i am going to continue to add sps and other light deamnding corals into my mixed reef, perhaps i should rethink my lighting.
i have two sets of light with significant overlapping with each pumping out the following PAR according to fluval
376 @ depth of 3″ (76 mm)
222 @ depth of 6″ (15 cm)
90 @ depth of 12″ (30.5 cm)
47 @ depth of 18″ (46 cm)
here is their blended wavelength
even though it's white led dominated, to me, the blended wavelength appears to have mitigated the imbalance of typical white LEDs, but i wold be very interested in opinions of more experienced people - would you consider these sufficient for more demanding corals? Assuming good water chemistry, would these encourage good growth and color?
edit note: the coral and fish are not mine, they are part fluval's posted picture of the wavelength so they made the trip to this post.
