HPS light superior vs current led tech?

[BigCube]

Appreciate the tip on heat generation makes me think to go for HPS during our very cold winter here at the coast. How do led grows generate heat in colder climates?

Not very much. My led is hotter than most led lights. But even it only changes the temp in my tent by like 2 or 3 c.

I climate control my house, then adjust the tent to meet the plants needs. So the houses heater keeps a minimum 21c and the ac kicks on at 23c. So I. Always within that 5
2c range. Making controlling the tents temp easier. With 2 - 3 c deviation, my tent only fluctuates 5c.

I am fighting 100f outside these days and keep the room 78f. I just have some hot times in tent temp up to 84f. Have started some AK auto flowers in pots today so will have those ready when y flowering is done. I use Two 300 w led and two fans and humidifier so get heat from that too...I just knkw don’t grow photos in the summer.i will see how these do and decide if I want to grow autos or photos.
Happy growing

Admittedly they are exaggerated numbers. But not by much. I have a 250w led light that is outperforming the 400w HPS I used before. The led cost me $120.

At almost half the power consumption, its outperforming the hps by leaps and bounds.

If you are getting much more than 30% more than it isnt just the efficiency of the led. You did not achieve the full results from the hps and you are doing better with the led. Nothing wrong with that but your experience is not equal to the lights potentials. All of this is still mostly the grower. Lights are just tools and led is not 66% more efficient at producing usable plant light per watt.

I have grown with hps for almost 6 years perpetually now. I have more than doubled my yield and likely quality in that time with the same strains.

It is more about our growing habits and how well we work our lights in my opinion.

I grew with hps for over 10 years.
%30 better is about right actually. Again to reiterate, that's close to half again better than hps. On an led that takes almost half as much power, produces less than half the heat, and theoretically lasts much longer than hps. All for about half the price of the unit itself and half the power cost.

Again all round numbers but very close to actual numbers.
To me it comes down to par per watt.
The led I am using now puts out about the same PAR as a 1000w hps at equal distance. So it's no wonder its heaps better than the 400w hps bulbs I used.

Keep using what works for you
This led of mine is working great. It's cheaper, it's cheaper to run, it runs cooler and outperforms hps. To me it's a no brainer.

I just wanted to clear up the exaggeration but you just keep exagerating.

30% is not 50. They are not half as hot. Only “theoretically” last longer.

And the grower has to actually achieve the numbers or its just a sales pitch.

I use the tools i do because of the envirenment i am in. Only 2-3 months i need air conditioning but in winter my room needs the radiant heat and i heat my house supplementary with the exhaust. Saves about 400gallons of propane per year. Or the cost of a decent led grow lamp. :)


I am not anti led. They are grow lights. I love growing. They are far overpriced and over hyped and when they arent i will use them in Summer to reduce air conditioning costs.

I agree if you're talk g about name brand LEDs. But the one I'm using is cheap. $120. And it specs out as good as a 1000w hps. It draws only 250w and is seriously less than half the heat for sure.

If you get the chance, check out Amazon. Search for x5 cob.

What you say does not exist. Its all hype. Takes 600 watts on average to equal the output of a 1000 watt hps and that is with the best led diodes and drivers.

And even that is just a claim until a grower can master it.

Dont know what to tell you man. I've used a par meter to check the factory specified numbers and they are accurate
I the compared those numbers to factory specified 1000w HPS par numbers..

Maybe it's been awhile since you've researched them? As I said, par is what I used to compare them. I even measured my dad's brand new 1000w hps bulb, compared it to my led numbers in the exact same setup. The end result was my dad bought 2 of the LEDs and put away the hps.

Am I missing something?

 

[Kingjoshh]

Not sure why everyone needs to turn this subject into a pissing match...

Yeah, you should replace hps lamps every 6 months. You can absolutely go longer with them with minimal loss of production or quality, but like I said, in the grand scheme of what we're doing here its peanuts really. I can grow a lot of pot between each $160 lamp swap.

And I'm not claiming it to be the most efficient technology, but for my setup where I use the heat given off and electricity is cheap, Its a solid option. Covering operating costs is manageable, But forking out thousands and thousands of dollars for lighting setting up a room is sometimes just not in the cards for everyone.

Definitely wasnt turning it into a pissing contest mate, I was just surprised that you have to change it every 6 months that’s all. But you definitely don’t need thousands for good led lights

I run what I consider one of the top of the line LED out there. At 620watts it puts out 1450ppfd and the claims have been tested and verified many times.

The efficiency is I consider top of the led food chain. Cheap LEDs do not even come close to this efficiency. I run this light for 2 reasons the efficiency and the reduced heat because I run a sealed room. If I had a larger room and heat was not a concern I would not think twice about running HID. In fact I would probably run CMH for my own reasons.

Like I said many times LEDs are not LEDs and I cannot state enough how much exaggeration is going on by the cheap LED manufacturers. The issue is they mislead people with their unvalidated claims and those people take it as fact. They take charts and info from top manufacturers and make the same claims for 1/4 of the cost.

Put simply... THEY LIE!!

This will replace a 1000 watt HID this light is crazy good shit man. Shames my blurple lights

I have used both, HPS and LED's. Both are good, except LED's do decline in efficiency with in six months to a year and a half,(at least mine did). Here are my examples, the top two are the same plant grown under the Meizhi 1200 watt( actual wattage 568), I grew this blueberry strain pheno in one gallon smart pots, I netted two and a half ounces from just that one, and another blueberry(not pictured) for roughly three ounces. The bottom pic is an Ace TM mix, this one was grown under a 400 watt HPS, this is not a full cola and is a Sativa Hybrid, I honestly will probably see more yield from this plant than from my LED, other than that, the quality is the same. It really depends what you want, a 400 or 600 watt HPS is what you will use in energy expenditure, while and LED will fluctuate in savings. Admittedly, my LED's were mid range. I am sure the higher quality ones would produce better, yet I would give LED's a few years more before investing, mainly for the price will be lower and probably be more well established.

Dude your lights will grow plants no problem. Even the cheapest will. The reliability the fixture and the quality of buds might be a bit lower. This is where if you are limited on funds HID will produce better for the same cost upfront. If you want to attain the quality of HID when using led you need to replicate the output specs. But the specs need to be truthful in comparison. To do this a quality led is needed. There is soon much more to it. Light intensity is more important than spectrum, IR and UV have a role. There is sooo much to take into account and yet if you have the light intensity the grower will make the most difference. The rest does make a difference but not as much as light intensity and grower experience.

You have to start somewhere. And the reason I say if your not going to spend the money on a quality led then go HID is quality of the fixtures and light intensity. The cost is much cheaper for more with HID and it's not until you get into the higher end LED that they really start to compete or exceed.

Cheap LEDs work no doubt but for the same cost you can get an HID that will out perform it. If you can handle the extra heat. Also the fact that the cheap led fixtures themselves have a high chance of failure

Then I feel like I’ve been blessed to have no problems at all with my blurple lights, and I’ve hit my big ass head on them like 500 times at least by now so now im even more surprised they haven’t broke or gotten less bright LOL. We will see come harvest time if the blurples can crank out some potent and flavourful bud

Sure they will. Just might have been a little better. Hell people still grow with compact fluorescents.

I looked into, lighting my 8x8 with HLG boards was going to cost well north of 2 thou. I wouldnt personally use anything besides HLG if I was doing led, and theyre expensive. Then I would have to heat my shed on top of that for 8 months of the year.

HID was just more attractive. I can grow stadium with an HID lamp which I couldnt do with LEd which makes it even more versatile for me.

Just like @MIMedGrower said. Lights are tools. Just like nutes, fans, tables, and the brand of pump you use. All of this is just 10% of the equation. Don't get so fixated on the tools of the grow and focus on growing. Too much thought, time, and money goes into trying to get the best of a or this of b when in the end its all going to come down to how well you grow. Someone who has a lot of experience is going to kill it with whatever equipment vs someone new dropping a grand or more on lights. Just figure out whatever lights you choose to use and what kind of temp control you need. Then consider your yield expectation per plant and go from there.

Even with a 400w hps Ive pulled a lb off 1 plant in a DWC bucket in a c13 with a ton of training. Hell I remember seeing Tobar pull 11 or 12oz off of a 250w in a speaker cabinet off 1 thai plant without much work. It's all about goals and expectations. Figure that out and go from here.
