No, a good design LED lamp drive has little power lost, I believe in the 10% 
range. You can't affort to have high power loss since you need to dissipate 
the heat, larger size and more powerful components.... all these added to 
the cost.

The fluorescent lights looks complicated but looking at the price you will 
know it is not complicated to make. The problem is the cheap lamps which 
does not last long. The better one should last for over three years. Low 
power lamp is very important to us, we use air conditioner in summer, every 
watt of power dissipated by lamp will be doubled.
