In fact, the lumens of LEDs are increasing rapidly.

In 2009, the number of lumens per watt of mass-produced LED has reached 100 lumens, and this number is growing rapidly. The corresponding theoretical system of heat transfer has been mature, and the heat transfer means we can use are basically clear: conduction, convection, radiation and phase change heat transfer. Therefore, the measures we can take in heat transfer or heat dissipation are visible and limited.

Why don't hotel rooms have ceiling lights?

My hotel building is over 100 years old, so we have ceiling lights. We also need a ladder to change a bulb 11' from the floor. It can take 20 minutes for 1 bulb! This is one reason that we have changed to the longer lasting (and more economical) low-energy bulbs.

I would be delighted to have wall lights instead. Retro-fitting them would however be even less economically sound.

Higher than average ceilings mean ladders to change the bulbs in ceiling fittings, and this extends the maintenance time and convenience for staff enormously. Even normal height ceilings mean that a chair is needed to swap a bulb out. Wall fittings are so much more convenient for both staff and customers, reducing the time taken to get light again!

As Michael Forrest Jones says - anything other than a simple bulb swap requires the power to be cut to the whole circuit (which may be more than just a few rooms). This makes it very awkward to do emergency repairs after dark! -- Been there done that... Go with wall fittings that can be isolated in-room!

In short:

I have ceiling lights.

I don't like them, as they are awkward for maintenance.

Replacing them would be expensive and extremely difficult - basically a total rewire of the hotel lighting system.

Design engineers are not stupid. they note the first 2 points!
