Today the replacements for my blue spotlights arrived. I've been lighting my living room exclusively in blue for six months or so; if there isn't natural light there is only a strange blue glow reflecting back in off of the windows. The original bulbs were analog, and since I've developed a propensity for leaving them on as much as possible, I decided to pursue LED bulbs instead. Compact fluorescents are infeasible due to the shape of the fixtures.
The blue is different. It's almost into purple some times and has a blacklight-like effect at others. It's still a good ambiance for the apartment, or if not good at least desired, but it is almost palpably different from the analog blue lights.
I expect I'll adjust to it over the next few weeks, and any acclimating is probably well worth it, given the lower energy usage and longer lifetimes I am told I can expect.
