If heat's an issue, LED can definitely help fix that. Being in a fairly hot part of the country, I can't really run HID lights for a good part of the year. Exactly which LED fixtures did you have in mind? If they're the kinda low-end lights that I typically looked at, "1500 watts" is probably more like 250-300 actual watts. Make sure you sweat the details and find out their actual draw, so you know you'll have enough wattage to cover the area you need to.

I’m in Oklahoma so the heat is pretty gnarly right now! I was looking at the “king led” brand my uncle uses them and it says his 1000 watt led equals about 800 watts of my hps lights. Do you plants like the led lights? Do you pull decent weight/ quality with them?

Looking at something like this one?

It only draws 185 watts. Even with 2 of them, I can't imagine they'll do much for a full 4x8 tent. Plus, this is only opinion I guess, but blurple light sucks. I'm still too new to really have a feel for how my plants react to different lighting. All I know is that with my CMH, my tent regularly got above 90F; with my LED, I can generally keep it in the low-mid 80s.

To replace a 1000w HID, I wouldnt use anything less than a Gavita 1650e 646w x 1650 Umol

Greetings
Might I suggest visiting Rapidled or Chilled. Both COBs and QBs, You will dramatically reduce the heat in your grow. Not to mention reduce electrical bill.
Here's a pic of someone I kinda know who runs a 4'x8' tent w/RapidLeds lights. And a pic of my grow.
Hope it gives you ideas.
Success w/ya grow!!!
Cheers.

Those things are spendy but I like it maybe in a few months I’m gonna look into getting one to try out.

I definitely will! Do you know what model it is? And do you know what those bags hanging in his tent are?

I think they produce CO2, which comes in handy if you really want to blast the shit outta your plants with really intense lighting. I think it's recommended for those who want to give their plants more than 1000 micromoles/joule.

Here's what I'm looking at getting for my next lighting upgrade:

They're not exactly cheap, but very reasonably priced when compared to the original QB manufacturer.

but the price is kick azz.

I suspect there are really important reasons why they're cheap. I'm just biased now. I've found that the super-cheap LED fixtures tend to throw as much heat as light.

i'm sure your right... I didn't buy it.... I was just all over the place looking for those cmh sun 315 ra's

To illustrate my point, here are some pics I just snapped. The blurple pics are a $80, 250 actual watt fixture I got from Amazon:


These pics are from a 360 actual watt fixture that I got on sale for $175.


If heat's a big issue, be aware that not all LEDs are efficient enough to run cool.

Here's the CMH I bought. It was $145 when I bought it, though. Works great. Just can't use HID here in the desert in a house with no A/C.

1000w Hortilux HPS is 1600 Umol.

1000w Gavita is 2100 umol. And REAL HOT. Infrared on these are unreal.

The Gavita is 1650 umole. Anything less, and your production will suffer vs a 1000w HID.

Phillips is also coming out with a new LED, but will only be available by lots of 40. Its even more powerful than the Gavita, and is what all the major greenhouses will use when they come out in early 2020.

I got wind of them because a place near me is going to build a HUGE greenhouse, and use LED, and HID, and the Phillips are what they are going to use.

Philips GreenPower LEDs

630w x 1800 umol.

World's largest LED installation scheduled for Rowan County Kentucky.

A major agricultural project scheduled for construction in Rowan County says its 60-acre greenhouse will be outfitted with a $15 million hybrid LED lighting system.

This would make it world’s largest LED installation for a single building.

Through a partnership with Equilibrium, a greenhouse investment firm that is providing upwards of $100 million for the facility, the state-of-the-art greenhouse will utilize Philips GreenPower LEDs from Signify and will begin installation early next year.


AppHarvest’s controlled environment agriculture facility in Morehead will grow tomatoes and cucumbers. The structure is under construction and will open in the second half of 2020.

AppHarvest’s engineers have devised a hybrid system to dramatically reduce energy usage in the greenhouse and increase yields. The Philips GreenPower LEDs, which are 40 percent more efficient than typical greenhouse lighting, will be paired with Agrolux high-pressure sodium (HPS) lamps.

The LEDs produce less heat and will be used in warmer fall and spring months to grow more produce. During colder months, both the LEDs and HPS lamps will be used, and the heat from the latter will help warm the greenhouse and reduce natural gas usage. AppHarvest produce will be distributed to the top 25 U.S. grocers through partner Mastronardi Produce.


The LEDs will be installed by Dalsem Complete Greenhouse Projects, which is overseeing construction of the 2,762,073-square-foot greenhouse. The LED installation raises the all-cash investment by Equilibrium’s Controlled Environment Foods Fund from $82 million to upward of $100 million.

“This LED installation reinforces how our Farming Now movement uses proven technology to grow more fresh food with far less resources,” said AppHarvest Founder and CEO Jonathan Webb. “Eastern Kentucky is mobilizing to lead the real food revolution and become the AgTech capital of America. This is Farming Now.”

Equilibrium Senior Principal Marco de Bruin said, “This $15 million lighting deal is the latest example of how farming is undergoing a profound shift to utilize more capital and production infrastructure. The result is better meeting the demands of consumers, retailers and food processors for more reliable, year-round, fresher, and sustainable foods.”

The greenhouse is planned near I-64, right off KY 801 North, in the Sharkey area. The project is expected to bring 280 full-time jobs to the area.

You GET what you PAY for ............................

Person is using a 1000w HID, and probably 1600 umol. If he doesn't equal the output of the HID, his production is going to go down. Bigly.

yes sir

If someone's posts suggest they're on a Ford Escort budget, it's kinda pointless to write a dissertation on why they need a Roush Mustang.

were did you find that led light for 175.00 now I would of got that .....

It was on sale. Regular price is a bit higher.
