Meh I was there for those old posts. You never decimated a single argument. Ever honestly its laughable to think as such.

As too point number 4. Keep in mind that most growers outside of the nl dont have problems getting leaf surface temps high enough. Most growers struggle to keep their grow temps low enough and spend a large amount of money keeping ambient temps low under hps lamps.

So im not sure how thats a point in your favor.

Battle of the dogmas :P
out of 7 things he pointed out, that was the best you had???lol

The others weren't really worth responding too truth be told

He was right about one thing though, the same talking(rhetoric) points are being rehashed from the last hps v led topic....
just llike it was 5 years ago when they said led was so awesome. again,lol

Sounds cool but as usual bullshit. As to why you would deny that and call me a liar just after I did it again.... I can only guess it's because you have some wierd misplaced sense that I want to take credit for something. I do not. I was just reminiscing...

The fact is that you bibled fans have shown a very poor level of discussing led vs hps and an even lower level when it comes to dialectics. There are plenty of examples where I and others refuted, with facts and real world examples the hps nonsense and comparisons derived from it. Now including the above from which you desperatly try to pick 1 point. Note I said hps. I sometimes actually direct people to this forum, but with a note: the led info is decent, take the comparisons to hps with a bag of salt (one if those industrial size bags lol).

The most classic and possible earliest example to go into history is Supra and others claiming doubling the gpw at a time when the max efficiency was much lower than now. It turned out, that was actually true. Side note, the hps yield was 0.5gpw... Same thing with people spreading out the light so far they got higher gow than hps, but refused to acknowledge they needed extra space to even get the same gpw as hps.

One more example I refuted before, the nonsense of ignorant folks who think NL is in scandinavia or something. Many parts of the US get much colder... and I'm not talking about just Alaska. Additionally, there are growers in many other countries where it does get colder than here and in the US. Your argument is, such as many I refuted, just desperate cherry picking biased nonsense to avoid a factual discussion. It would logically make more sense to include a footnote in your led promotion that it's particularly useful and efficient in hot areas, rather than pretending it's not a well know issue recognized in the horticulture industry. We're digging holes to the earth's core just to overcome that.... How's that for efficiency.

Anyway, have you ever measured the leaf temperature of your plants throughout the crop? Can you show me some data? I look forward to switching to led and show you how to use a growlight properly, but I can't simply solve the (lack of-) heat issue by putting my head up your ass too. Might keep me warm but not my plants.

Hey if you like fiddling with dainty glass bulbs every year, go for it.

Me, well my lights can take a fall onto concrete and keep chugging.(tested that already). a light dusting once a month is the only servicing they need for the next decade.

Oh and using less power is nice too.

So you're basically ok with someone using imaginary and heavily skewed numbers for $, watt, and lumen of hps when it comes to comparing it to led. I know man... that is exactly your problem.

been going to maximum yeild grow shows for years. haven;t seen led displays there at ANYTIME,]hmmmmm. and if replacing a bulb is your best argument, you are reaching hard dude. you keep failing on your points here. but keep trying to convince yourself otherwise.

No im actually not ok with that. Nor am I doing so lol. Im using led because I ran my own numbers and my experiences with hid lighting. Im interested in results, not anecdotes.

Im giving lec a chance but I doubt it will hold up as nice. We will see.

After watching the results from other members and before my own eyes from cob lighting. Im sold,they make me look good and im a crappy gardner lol.

Im not convincing anyone. Nor trying too. Learned long ago that thick headed individuals will do as they wish.

Bulb replacement isnt my only motivation. I have many reasons, most of which are lost on ostriches

I like to think of my led no different than a HPS set up.
Ballast = Driver
Hood = light fixture
Bulbs = COBs
What a good platform is built, some day when it is cost effective I will change my COBs, maybe 2018, at a similar cost as your bulbs.

What lighting do you currently run mongo? Reflector type? PM me if you don't want to say on the forum.
Yes air cooled. Have it where 1 12 inch fan cools 6 hoods, so 2 12 inchers in space above. This allows me to get super close and get some great depth. You'd be shocked that I'm so close with the lamps to the canopy. And part of the reason I'm nervous about the cobs. Just unsure of the depth lighting. Not saying those fuckers don't dig, i just don't know. Maybe soon. Would consider trying one 16 cob fixture in replace of one air cooled lamp. Truthfully just scared to change a good thing i got going. 4x4 foot print on my air-cool, would love to get a 5x5 footprint. Gavita out of the question in there for me 9 foot ceilings already dedicated a 3 ton a/c in there also.

look at nanolux, you get an extra 8 inches with them. I run gavitas with 8 ft ceilings and I'm growing more weed than I ever have.

is that the custy mag at the grow shops?

after you visit the hydrofarm, sunlight supply, GH, advanced nutrients, and canna booths do you just go home then?

What exact model reflectors do you use?

I wish they would come out with a AC/DE type reflector with a replaceable insert so you could freshen it up at lamp change like a Gavita
