Hey guys i was just about to get a Gavitta

https://www.google.com/search?q=Gavita+Pro+1000e+DE+Lamp,+120/240V+&ie=utf-8&oe=utf-8

Or a
Spectrum King Led SK600
https://www.spectrumkingled.com/product/spectrum-king-600-led-grow-light/

I have bin hearing that LED gives 95% more of what it is

and HPS 1000 only gives 30% of what it needs and the rest is just heat so like
a 1000 watt is really only giving it 300 of what it needs.

Not talking heat difference i know led is less hot then HPS i am talking about what the plant actually takes in from each light



thank you Much appreciated

the percent of efficiency varies wildly between LEDs, it all depends on which type they are, Spectrum King kinda a crappy LED and gavita is a really good HID light, the gavita would be much better in my opinion.

Ok cool thank you! so how much percentage of efficiency of the 1000watt Gavita do i really get?
Thank you again.

The reality is the best of the best LED's are going to be equal in par efficiency to the Gavita and cost 4x the $$
More moronic statements from clueless people. Running CXB3590 @ 50% is giving you 56% efficiency. No Gavita can get close to that number. Want to spend 4x the cost of Gavita? Now you are looking at 70% efficiency from COBs if not better. Better yields, lower energy and cooling costs, evens out just a higher initial investment.

Please stop talking out of your ass. Not only that, you have bulb replacement every 12 months which are pricey and you begin to lose efficiency over those 12 months.

And to add, you can setup a cob array so you get very even spread of light instead of 1 penetration point if you DIY which is a huge bonus for yields.

Where do you even get those numbers from or do you just make them up

Binning conditions are 2.4 amp current and 85 degrees. The actual result will be better if they are kept at 40-50 degrees and when lower drive current is used.

1000w SE bulb is around 1.07 umol/j
1000w DE is around 1.7-1.9 umol/j
3590 at 2.1 amps and 50C is around 2.3 umol/j for the 3500K 80CRI variety.

So the single ended bulbs will be less than 30% efficient. DE bulbs 37-42% efficient and 3590 around 50% efficient, 56% at 1.4 amps, 64% at .7 amps. About 70% efficient at .35 amps, but almost nobody is crazy enough to build them at currents that low.

That's cause they wouldn't output shit for light and would be a waste of money/space/effort, lets be honest it's best to push them a bit harder so you can actually grow big buds and not have to lower the light too much.

This is the actual data for the BEST COB on the market.

http://www.cree.com/LED-Components-and-Modules/Products/XLamp/Arrays-NonDirectional/XLamp-CXB3590
Don't see where it says 70% but I do see where it says this

Maximum Efficacy at Binning Conditions 162 lm/W
seems like there are still a lot of exaggerations regarding leds. on that link they don't show the operating current that efficacy was achieved at but looking at the data sheet that site links to it seems 140 lm/w at 25C at 84 watts is the best been listed

No ones really doing that. The manufactures would love you too, but no one is. That goes for all HPS bulbs.
Great, no one does it, but in the end it effects the efficiency levels. The longer the bulb runs, the less efficient it is so when someone talks about HPS/MH/CMH being more efficient than LED, they need to take that into account.

Grow with COBs after growing with whatever. You will quickly realize they are not hype. Plenty of us know this its only the ignorant who do not like change who dont believe.

I never said they were hype. I own 15 of those little fuckers. Ill make a play with them soon hopefully.

actually LEDs lose efficient over time and some of us have tried LEDs and gone back to other types of light. I'VE tried vero18s as well as chinese leds and was not impressed. I like LEDs for lighting my home but not for growing plants

You have used a gavita then? You make all kinds of crazy claims that cannot be substantiated ever, and you never have any actual data to backup your claims just wild claims of how amazing LEDs are and how crappy HID lights are. I have tried COB's , monos and HID lights, I prefer the HID lights over the LEDs for a multitude of reasons but the main one is they grow more buds of the same quality or better quality.

Claims? Really? Ive posted plenty of shit and pics to back up my shit. Maybe you havent been around long enough. I never said HID is crap but LED is superior.

Many other people have backed their shit up with LED. You are just one of the ignorant few who cannot accept an adapting market.

Where are the scientific facts though? like I posted a data sheet from cree all you posted was your opinion. I get you think LEDs are better but please prove it with actual facts and not just "these are better" .

You posted a datasheet that you did not understand. GJ
Really? It's still facts that I posted even if my understanding isn't as indepth as yours, please educate us with your information that shows that COBs are better than top end HID lights, I really want to see it cause I want to do the best I can with my plants too you know I grow for medical purposes so if you got some info that can help me reduce the pain please help.
