They've been starting to retrofit the streetlights in my town with LED. There's some places where there is one hps and then the next light is LED. Those leds are super bright. I heard they even got complaints that they were too bright and had to turn them down. I'm not convinced on led either, but the technology is getting better and better.
Ok , well i have never seen them outdoor here but fair enough if you saw with your own eyes,
Understand i am not an led hater and indeed some of my friends use them,
I want to use leds , the benefits are obvious , heat , energy consumption etc. .
I will still have to add fresh air anyway so if you think about it i would prob need to warm the room up.
To match what i produce with hid , i would have to invest thousands ,
I say again i am no hater , i have done a lot of research and when you get down to it , commercial growers using led always say , im nearly there , or , i just need to tweak this and tweak that, bull , they are struggling and were sucked in by heavy advertising , the want to improve and be modern and high tech,
Plenty have gone back and plenty have struggled on or used them for veg or supplemented lighting.
I am not going to put myself through that , not when its blatantly obvious people are struggling,
At best they are a match for t5,8 etc or for the hobby grower.
I agree technology is moving on and i have no doubt they are the future.
This is my opinion only.
