With Reefgeek going out surfing, my source for ATI bulbs was gone. It was time for a bulb change so I decided to give the new Giessmann bulbs a try. All I have to say is WOW…… With the ATI bulbs, I almost had to go with a 18k look to get the pop I was looking for out of my corals. With the new Giessmann bulbs, I’m able to get the 14k look I really like but still get the pop from the corals. My previous bulb config was
Front
B+
P+
B+
C+
B+
B+
C+
B+
This gave me about a 18k look. In my eyes, it looked too much like tidey bowl water.
With the Giessmann bulbs, I’m able to use

actinic blue (ATI Blue + equivalent)
super purple (ATI Purple + equivalent)
actinic blue
tropic (GE6500 equivalent)
aquablue-coral (ATI Coral + equivalent)
actinic blue
aquablue-azure (This is new colored bulb and I would have to say it’s in between a Coral + and Blue +)
actinic blue

Overall, I’d have to say, I really like these bulbs. I took some PAR readings of my 6 month old ATI bulbs and the new Giessmann bulbs and of course the Giessmann read higher because they’re newer. I would have to say the PAR is comparable to new ATI bulbs. I’ll post some pictures probably this weekend of PAR readings I got.
