decent T 5 bulbs handle dimming well.
You can always go for the stand alone doser if a full control system is not what you are looking for its just an option.
But GHL profilux is not just dimming and pump control
ph control
temp control
redox control
salinity control
level control
oxygen control
humidity control
tunze control
lighting control
weather pattern modelling
day night moon modelling
Thunder storm effcts
internet access
dosing pump control
Phew and that just scratching the surface
