I doubt this as they dont even have the same spectral output.I have the AquaMedic Planta and love them. I have an inside source, who told me that AquaMedic purchases the bulbs from Giesemann and relabels them under their brand. Basically, they are the same bulbs, just priced differently.
Giesmann Aquaflora:

AquaMedic Planta:

The Planta has a much smaller green spike and the red is quite a bit higher in the nanometer scale - a true red vs the orange of the Aquaflora. Personally, I think the Planta is a better bulb for plants based on the graphs.
