The potential of LED technology to produce high-quality
led is expansive because, led is the future of light,, we now got a switch from the old light bulb to led, there is a marketing thing going on. you also can not say that led is so ''expansive'' because you pay for the name. i just know a lot company's that arend expansive and have great products.
but i do agree that led is more expansive than the conventional lighting fixtures, but that is a mix between marketing and also lifetime of the led fixtures
because LED is a new technology. and we use it to save energy and its looks so beautiful then conventional lighting fixtures. that way LED is expensive.
New technologies normally start with high prices to cover the research and development investment, with time the cost reduces and gradually close the margin between other technologies to be able to take over the market.
this is applicable for LED technology as well, you can review Haitz's law as it covers this point in detail.
It states that every decade, the cost per lumen falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light.
