I know you whole heartily believe what your saying is correct but I just want to flood people with the data they don't normally see because it's hard to find.
I'd rather take the word of our United States department of Energy over a bunch of people just sticking 2 lights next to each other with no knowledge of how lights even work.
CALiPER is actually a program by our government made to compare the lights to help LED's in our marketplace.
"The U.S. Department of Energy (DOE) is a federal agency working in the public interest. Published information from the DOE SSL CALiPER Program, including test reports, technical information, and summaries, is intended solely for the benefit of the public, in order to help buyers, specifiers of new SSL products, testing laboratories, energy experts, energy program managers, regulators, and others make informed choices and decisions about SSL products and related technologies."
I'm all for the best lighting solution. It's just from all the studies I find tend to say the same thing.
I would love to find a real study showing LED's are superior but I just can't.
Yes the last study I posted was from 15 years ago but every study I've read following that date has had the same results.
What makes LED's more efficient is that they last longer, use less electricity, and the ability to aim the light like you said, directional. But that's really a tricky statement if you start thinking about it.
Flouros send light in all directions which means you need a reflector to aim your light. LED's just being directional constitutes the claim of being more efficient, but like the study I posted shows, more efficient doesn't always mean better quality of light.
I think what makes LED's a better solution for streetlight and such is the fact that they do last longer. It's not because they put out more light.
When cities make decisions like this they take literally everything into account. The gas cost from traveling all the way down to the wage they have to pay the crews to change out the light.
It's very easy to see that in situations like this it would be more efficient to use LED's. But still, is a better quality of light produced?
I'm trying to show there is a difference when you take everything into account.
Yah, your right when you say I haven't grown with them and my claim towards plant growth is all hypothetical but I still stand by my claim because I have seen the proof and the studies behind it.
LED can only be so big and can only produce so much light. When you calculate how much physical space they could possibly occupy, along with how much light they can actually produce, the math proves they are inferior QUALITY of light.
