Amount of luminaires
Being there is a renowned advertising agency from Amsterdam, The Netherlands. It is housed in the well known Vondel church. The high vaults naturally produce a vast amount of reverberation. Great for choirs singing, less so for creative brainstorms and office work.
Thanks to installing three Round&Round 120XL luminaires over 33 square meters (355 square feet) of acoustic material was introduced into the space. This large surface has reduced the reverberation time from 1.9 seconds to 0.9 seconds.
