Why are LED light bulbs so expensive?

Components on the circuit board is often assembled by hand because its still too complicated for factory machines. The actual LED wafer can cost as much as $8 a unit. The brightest LEDs generate blue light. ... Although LEDs burn cooler than Edison bulbs, they still need a conducting material to dissipate the heat. read more

Less Energy and Money Saved With all the talk about how expensive these LED lights are to buy, some people are probably thinking there is no way they are going to go out a buy a bunch of fancy, expensive light bulbs. read more

The actual LED wafer can cost as much as $8 a unit. The brightest LEDs generate blue light. So in order to get the more natural white glow, manufacturers typically coat the bulb with yellow phosphor, an expensive rare earth metal compound imported from China. LEDs additionally require the use of drivers to convert energy into electrical current. read more
