Have the showerhead for the shower in the sauna to buy here too a little colorful light reinzubringen because you because anyway likes a little darker and also represents a great transition from the sauna-light therapy. The humming during operation does not bother me particularly, There must come a power source coming from the LED's to light up to bring. Even the color change depending on Temoeratur works perfectly so far, however, the color logic not quite understandable especially cold water blue, hotter water but appears only in my green, presumably because it takes more than 60-70 degrees to switch to red. But there is no need for the sauna anyway because showered cold with us! The light is otherwise not too intrusive and but enough to illuminate the shower adequate.
