And can you explain this answer to the readers please? How do you justify your answer?

I think plasma will be the next big thing in lighting - LEDs will fall by the wayside.
take it from someone who has used leds in the past...if u can get a ufo led i would DEFINITELY recommend it. u need a high led/plant ratio, but if u can afford it, do it! they work amazing. i spent 130 and a blue ufo led and it works awesome, is quiet, and doesnt get hot at all. you can have it like 2 inches from the tops of the plants. sooo good. low wattage and cheap operation. 100 % awesome. these people who diss it just havent actually tried it yet. trust me.

There are plenty of grow ops that have journals of LEDs pulling 1 gram per watt of good tight nugs. They use less power. They reduce the risk of fire. They don't waste 85% of the energy they consume, they don't require duct work and additional ventilation. Out of everyone here telling the poster LEDs suck, how many have actually used them? And I don't mean the $25 panels on eBay....

Of course LEDs work, and they work quite decently in fact; its just the price that gets most people running away from them. Over a longer period of time im sure they pay for themselves over and over again, but i think ill stick with my good ol' outdoor sun to grow for me.

LEDs work that's all there is too it. How well do they work, in the right hands very well so far. The good LED's produce the best results, like they say you can buy the hay before it goes through the cow or after.
The one issue I have is all the LED's on the market have commercial LED's in them not Agricultural LED's which are available but more money. The commercial ones are used for office, factory, street lighting and automotive to name a few. Wonder why, must be price?
The other issue I have is in the flower LED's, the amount of blue is critical and specific to each plant species. Only after extensive testing can this be determined. Present research supports this with examples of Blue light requirements ranging from 6% to 80% for different plants. Plants will use what ever they can get but that does not mean it's the best for the plant. More research is needed in this area.
Plants need both red and blue light for photosynthesis.
Red light is very important to plant reproduction. Phytochrome pigments absorb the red and far red portions of the light spectrum and regulate seed germination, root development, tuber and bulb formation, dormancy, flowering and fruit production. Therefore, red light is essential for stimulation of flowering and fruiting.
Blue light stimulates Chlorophyll production more than any other colour, encouraging thick leaves, strong stems and compact vegetative growth. Chlorophyll absorbs blue and red light and transmits the energy to a pigment-based electron transport chain. The energy is ultimately used to produce high-energy chemical bonds that can be used for a range of biochemical transformations, including fixation of carbon-dioxide into sugars. Carotenoids, the yellow-orange pigment in plants, absorb blue light and control leaf fall and fruit ripening. Riboflavin (Vitamin B2) absorbs violet light and influences "phototropism", the movement of plant foliage in response to light.
