What makes these bulbs so great is that ,usually you sacrifice par for color ,I find these bulbs to be a happy medium & also the bulb does not loose spectrum & intensity as quick as some other brands.
Here is a comparison of Aquaconnect 14k DE on Icecap Vs Geissmann 20k DE on Icecap
on Pfo
as you can see it spikes a bit bluer & also has more than twice as much par.
after using this bulb for a while I noticed better color because of the new spectrum & also more intensity,many others have reported the same.
I think Rob here runs one & a few other people as well.
In Alberta Golds carries them
Bay side corals in Sask
Hidden Reef/J&l
I will update you guys when they land
