Osram Kreios LED lighting fixture

Does anybody have any experience with installing these fixtures?. I'm cross bidding for a hospital install and they want to use something like these for direction signage. Does anybody have any other options that they know of?. Basically they want 15-20 of these in the halls to direct people. Glass gobos projected on the walls or floor with coloured arrows and names... Obviously it's a bright space, and I forgot to ask what the ceiling height we are delaing with, but I'd have to guess 10-12 feet...
They also don't look like they have "replacment bulbs", so I guess you're buying a whole new fixture if it goes... that's not very "green".
Hoping somebody has used these and can offer up an opinion or an alternate...
thanks
