Why isn't Boeing offering mood lighting on the 737NG? It is standard on the 787 and 747-8, and is now an option on the 777-200LR/300ER. Airbus is offering it on the A350 and A380. It is also now an option on the Airbus A320 series (featured on Virgin America). The 737RS and Airbus NSR will probably also feature it. Why isn't Boeing offering mood lighting on the 737NG? Please correct me if I am wrong.

How bad can your mood get on a flight that can't take much longer than ~5 hours max? The white LED lights are something the airlines probably want, as they're extremely long-life, reliable, and light as compared to traditional lighting fixtures...but otherwise, the "mood" part of the package is pretty much wasted on any standard 737 configuration.

Because most airlines don't give a crap if the cabin lights can turn purple and green, they just want a good aircraft at a reasonable price. Add that to the fact that the 737RS will be flying within 10 years, and the fact that the 737 is still selling like hotcakes, and you have your answer.  Wink

It is due to the short-haul status of the 737. It is less expensive and easier to use for F/As to just have the traditional lighting variances: all lights on, lights dimmed, lights off (excluding the reading lamps, of course). On a short-haul flight, those three variances are just fine when it comes to "mood lighting," even if they don't change colors like an artificial sunset. All lights on works just fine when boarding, deplaning, for the safety demo, and on nighttime initial approaches. Lights dimmed works just fine on evening, but not overnight flights. All lights off works just fine for redeye flights, takeoff, landing, and on daytime flights where the sun is bright enough to light the whole cabin.

But Airbus is now offering it on the A320 series. Boeing should consider offering it on the 737NG. It is standard on the 787 and 747-8, and is now an option on the 777. I believe that Air Canada's new 777s will feature mood lighting. Before the release of the 737NG, Boeing made an updated PSU for the 737 Classics and 757-200. The updated PSUs are the same type that are now used on the 737NG. The newest 767s feature a 777-style interior, featuring large pivot bins. Boeing should simply do a bit of modernization like they did in the past.

I think you're missing the point, dramatically. It's a short-haul airplane. Mood lights are useful for long-haul where people are trying to sleep and fighting their circadian rythyms the whole flight. In a 737 on a short hop, pink and purple lights are a waste of weight and fuel. Updating the cabin is one thing, but offering a feature that is not really in demand just because Airbus does it doesn't make any financial sense at all.

Perhaps, but I don't believe it would cost all that much. After all, LEDs are cheap and the logic to do various lighting is trivial. So why not offer it? Especially if Y1 is to encompass the 757-200 range.

Y1 is a different story. They have to invest in a new cabin design there no matter what happens. At that point it makes sense to direct the full feature set available using currently available technology to that cabin. What doesn't make sense is rolling out a huge new cabin project for the 737 for mood lights when the Y1 is going to be rolling down the assembly line in the next 10 years.

You do cabin-revamp projects when there's a compelling reason to do so. The ergonomics and space efficiency of the 737NG cabin are very high (hence the retrofit to the 757 line) Any revamp of the cabin will need to be dramatically better for operators and passengers. Mood lighting will just be...dramatic.
