does anyone thing that some energy does get wasted in other light sources?

What I mean is this. Lets use 100% of an HID lamp. just an example not accurate information. just assuming.

HPS - these emit more then just 1 color of the spectrum. infact these emit all the colors in the spectrum that are visible by humans.

ok so say that the HPS emits:

50% - red spec
30% - blue spec
5% - green spec
5% - yellow spec
10% - white spec

ok so there are colors that are not needed for growing. main colors are blue for veg and red for flower.

so for the 20% of light that are not these colors. Isn't there some wasted energy? Say you have a 1000watt HPS. Out of all the light being emitted you are not using 20% of it.
So would this mean you are using 1000 watts of power and only getting 800 watts of usable light?

If there were HPS that emitted 60% - red and 40% blue. To me that would be more efficient.

When it comes to LED grows I have read a load on this. There are some people who choose to grow with LEDs over any other light because of some of the benefits to it.
Seeing as how you can get the colors of the spectrum that are needed and that is it they just may be more efficient. Not saying that they are but if you could afford the right system and more experimentation was compiled and the technology was tested a little more they just may be.

Time will tell when the little babies get cheaper and cheaper I am sure more people will at least experiment.

We can't rule out that they are not more efficient as of yet because we don't know what they are fully capable of. I know that they are bright as hell and certain colors can be narrowed down to ones.

Not only that but they also come in many angles. narrow ones and wider ones. The right combination may prove to be really useful. Plus the little suckers can touch the plants without harming them. I like that idea i know that.

How many people on cannabis know how an LED works? If some have questions on how they work and produce light I will be more then happy to explain.

One more thing

Some people need to think a little simpler. Rather then scientific theory. (yeah i said theory). Think more of the quality of light rather then how much can be produced. Granted these are factors that are important but. Quality of light meaning right spectrum and how it relates to everyday light emitted from the sun. What can be narrowed down to what the plants need and what they don't need?

Time will tell when the technology becomes more explainable and cheaper on everyones wallets.

As of now everyone used HPS, MH, Tobes and CFLs. What was being used 20 years ago or even longer? Technology will improve and other light sources will be avalible for use that might prove to be worth a try. With the experiments that have been done with LEDs so fa these have proven to work from start to finish but growth rate and all that stuff may be less then with conventional metheods but LEDs have proven to work.

Ok I am done. Mine hurt gotta go numb it with a visit to the bongo room.
