I might be wrong, but I think Paris is still using the set of spotlights they received for the 15th (!!!) anniversary for The Enchanted Fireworks. Based on this video, the placements seem to be the same as Dreams! and Illuminations.

By the time Illuminations opened in March 2017, Anaheim already had their new set for Disneyland Forever, while Florida's was being prepared for Happily Ever After's debut in May 2017.
I do hope Paris will get a new set of spotlights in time for the 30th. It does look like there'll be new entertainment planned for the anniversary, since the Director of Entertainment Operations let the new-parade-for-the-30th cat out of the bag during a Disneyland Paris Career Fair.
Wasn't that before COVID? Also with a new Christmas Parade for 2020? Are those plans still going forward??
