I have flown a lot of miles over the years, and I don't ever remember being on a flight where they turned the cabin lights off during take-off or landing. During the push back from the gate, crews will switch the lighting power source to inverters, which will cause the cabin lights to blink off for a few seconds and then back on, but there is no reason to turn the cabin lights off specifically during the take off and landing phases.
The cockpit is separated from the passenger cabin by a solid door, so there's no way that the lights in the passenger cabin could bother the flight crew in the cockpit.

As an aircraft performance and flight test engineer, (we are the guys who test the aeroplanes before the public or "smart" airline pilots get near them) I have never heard such BS about saving power, the aircraft performance is firstly based upon an engine failing at the worst possible time during the takeoff ( I have done many of them for real) and the remaining engines developing the thrust based upon the current conditions. During the analysis the worst possible generator loads are taken into account but they have very little effect in the end and the lighting system load is minimal compared to the rest of the loads on the engine. The only reason is to provide an environment in the cabin that if an evacuation has to take place the passengers do not waste time getting adjusted to the darkness, and if the worst happens it will very dark. I despair at people who get on an aeroplane and take their shoes off before takeoff, if they have to get off in emergency on the proverbial dark cold wet stormy night when the aircraft slides off the end of the runway and they have to walk through wreckage and flames, they have a little problem

Aircraft dim lights during landing and takeoff because it is a stage of flight when the aircraft is most prone to accidents and crashes. Dimming the cabin will adjust passenger's eyes to the amount of light outside, so it won't take time for the passenger's eyes to adjust in the event of an emergency.

the standard reason is so as that your eyes are adjusted to the dark in the progression of an emergency. Its is obviously prevalent in aviation that Take off and touchdown are the two situations that a crash is maximum possibly to happen. Say you have been entering into for a touchdown at night, and the lighting fixtures fixtures in the cabin have been on. Then the roof have been given ripped of from the fusiladge (It has handed off). Your eyes, being adjusted to the easy, would decide to comply with the dark of the sky outdoors, and you does not be waiting to be sure what is going on o.k.. this would decelerate the probabilities of you attending to protection. additionally, say there became right into a fireplace. with out inner lighting fixtures fixtures, any bright exteriour flames happen rather for sure in the dark sky.

any light source in the cabin creates a mirror effect on the windows for one and the plane uses a lot of power to take off and land and by turning off the cabin lights it saves power that is used to run the engines and hydraulic systems. that is also why they tell you to turn off all electrical devices at take off and landings

By dimming the lights, there is less stress on the electrical generators, which are part of the engines. Take offs are the most critical phase of flight. The more available power, the better.
(This is solely my educated guess)

Very good question.
I myself am a pilot, and I have studied this, too.
The two main reasons are :
1. To save power
2. Although, it is a slight effect, the light may affect the cockpit, and we may get a glare in the screen, thinking it is another airplane.
This is why Boeing and airubs are making airplanes that will give off dimmed neon lights, instead of suddenly shutting off the lights.

Theres generally 2 reasons for this:
To give more power to the engines and hydrolic systems and to keep from having a "glare" effect in the cockpit.
Contrary to what some are saying, it has nothing to do with crashing. Airplanes are the safest form of transportation.

As you know airplanes do not have wing mirrors so if there is a fire on the wing the passangers can see this more clearly with the blinds open so there is no window glare with the lights dimmed......
