I just ordered some new bulbs and they arrived today, while trying to figure out which combo I was gonna go with I started looking at the light output charts from the ati site. I guess what uim confused about is when I see the sharp peaks in certain ranges
Below is the chart for the ati blue+
http://www.atiaquaristik.com/de/t5-leuchtstoffroehren#
it has a strong peak right at 450nm but then has a gradual sloping towards the greener end of the spectrum with another spike in green and yellow
heres the one for the old school ati actinic
http://www.atiaquaristik.com/de/t5-leuchtstoffroehren#
This bulb has the same spikes in green and yellow and the same peak at 450 nm but slopes down towards purple .
Now since both of these bulbs peak at 450 nm why is one so dramatically different from the other when it comes to par (grimreefers numbers blue+: 311, ati actinic: 137)? Is it simply because the blue + has more output in the blue-green spectrum even though the intensity of that part of the spectrum is relatively low compared to where it peaks.
If someone could explain the peaks and their importance to par and over all color i would greatly appreciate it. Im currently using 5 blue+, 1 aquablue special, 1 kj fiji purple, and 1 ati actinic. I really like the ati actinic its super bright (significantly brighter than any other 420 actinic ive ever seen (current, wavepoint, uvl, giessman) im almost wondering if my bulb was mislabled or something, because its color looks way more like the output of the pro color than of a 420 actinic.
