I am looking into buying some 5W LED 3000k GU10 spotlights with a rating of 450 lumens, for my gypsum soffits. The only part which is confusing me is what viewing angle I should get. I have found a lot for sale with a viewing angle of 60 degrees, 90 degrees or 120 degrees. However I am not sure which to opt for. At the moment, the best deal which I found is on a viewing angle of 120 degrees. Would it be a good choice?
Below is a plan of how my spotlights are laid out. The main bedroom already has 4 spotlights which are not shown on the plan.
Would 120 degrees work for these rooms? Or else, should I get different viewing angles for different rooms?
