ohhh at what height mate? ohhh no, lol, im not getting into making any wild comparisons etc...too many different variables here to compare.
But i will, as i feel i have to, explain my opinions on it all, Tis just my opinion tho ok everyone? cool.
Its like im the UN of LED's here, wearing a bright blue helmet in a war zone. nice. lol.
So lets just take one point to consider then shall we? Yield.
so based upon that fact alone, im gonna play it real safe, 160 = 250W HPs easy 320 = 450W HPS easy.
But of course it all comes down to the gardeners skill aswell doesnt it?
Ive seen people pull 1.5 Oz under 3 1000W HPS bulbs, Gavitas aswell, why? Poor PH. Poor Temps.Poor Gardening basically,. Not the Lights fault eh?
See ma point?
so thats why comparisons to HPS cause so many rows/problems.....
There is a chap on here tho that i was kindly pointed to, showing a comparison grow between HPS and Apache Tech LED, dude,
maybe hes the best person to ask?
as for me, ive seen all sorts of results with HPS in the past, Good ones, mind blowingly good ones, but especially bad ones. Cracked bulbs, dodgy humming ballasts etc,,,,
So I had enough of HPS etc.., not for the cost of running but the safety of growing with them, plus the other issues they bring.
On a Average, 85% light loss from HPS is a bit concerning to say the least aswell (thats 85% of your electricity going down the drain you know?)
And too many horror storys of accidental fires..Plus theres the heat issues and the noise it takes to clear that heat, not exaclty stealthy.
so to properly compare both from those points of view would be easy, but results?, I just let the growers decide whats best for them innit?
Its like owning a car, yeah little super fast cars are nice etc.. but when ya got three kids and a dog, practicality kicks in more dont it?
so we buy something more suited to our lifestyle, but that dont mean we got to lose all the fun, you can get some 'grandad' estate cars that are fast...volvo T5-R series for example.
So LEDs to me, are more like that. As funny as it sounds.
They are a new Tech, meant to be used for different reasons, ie growing in smaller areas, more stealthy, more maintenance free, just get on with what you want to get on with, and thats growing.
After all, Any Light would be useless without a grower using them eh? just like a car without a driver in the first place. Useless,
Peace Bro.
