Lighting AutoCOB 55 Watt COB LED Grow Light

[Jewbilee]

Thanks nekvt!

I can figure out the lumens but it’s not really used by anyone outside these Chinese companies. As @Frenjamin Banklin mentioned it’s a hard task to compare grow lights. Light output is one way but what’s really the most important is giving the plants what they want and doing so in the easiest way and not wasting wattage is key. Most think higher efficacy or more wattage will give you bigger plants. This is 100% false. An example is if you had 300 watts of cobs 10” from a seedling and a 10w light bulb 10” away the light bulb would do better. In the end it’s best to look around and see what others are doing with the lights. Finding someone who has the wattage, intensity and spectrum part figured out will lead you to the best company. The most wattage, highest output, most cup holders.... won’t.

Hopefully this makes sense. It’s something that soooo many people have wrong. I just read a comment where a guy swapped his lights out and now says his plants have grown twice as fast as previous grows. Same wattage, same spectrum and a 5% efficiency gain. All this equals is 5% more light if the light was kept at the same height. The funny part is if he raised the new light by 1 inch he would be giving his plants less light even with the efficiency gain.

I know of how well the autocob performs.
I spent the last 6 months using them. Unfortunately I got in a fight with my partner, and no longer have access to the ones I bought in September, and dont really have the cash to repurchase 6-8 lights.
I am working, at the moment, on building a light from the samsung h series strip LEDs that I can get a hold of for relatively cheap.

How could it be that the amount of light (lm/w) has no effect on the plant's growth?
It seems to me that should be exactly what matters.
The example you gave about using the wrong lights for seedlings does not really hold water. I am not talking about using the wrong loghts, I am talking about using the right lights and just trying to figure out how much light they give off...

Probably get better answers if you start a thread in the LED lighting area.

The reason lumens doesn’t work best for figuring the output is not all light/lights will give the same reading. Green and blue will spike these numbers and the reason why most Samsung strips read higher lm/w numbers. Not that it’s bad it’s just not an accurate way to judge light. A 100w of green led vs 100w of red led will have different lm/w numbers. I’d choose the red whole green would measure higher.

Par which is the total output is also difficult. The reason is red and blue will spike cheaper meters. Then factoring in optics. If someone uses lenses and takes measurements directly below the light it will read higher but in a smaller area.

My above example wasn’t about the lights it was about the amount of light. If we knew exactly how many lumens a plant needed, or how much ppfd, par, light, wattage it would be easy. The point is trying to find that right number and this usually comes from the company and not just the light. What I would recommend would be different then another company. I give this recommendation based on the grows. Any more or less has a negative affect so where it’s at is perfect.

Hey all, noob here with a noob question, and i apologize if its been answered in these posts already.
The setup...
I am currently growing 1 auto in a smaller tent and am bumping up in size so i can grow 2 ladies and not be cramped. I think i want to try out a cob, so heres the question.
If the setup is going to be 2 cobs for 2 plants, is it better for both cobs to be the same spectrum? Which spectrum would best encompass the grow from seedling through flowering?
Tia, and im a bit elevated so apologies again if i asked a question thats been answered a 1000 times lol. Thx afn!

"elevated"...i like it!

Maybe too elevated, i just pulled the trigger on 2 cobs from the cobshop lol. 1 week in to my first grow and im already upgrading the operation lol. Cant wait to get em and get em set up in my new tent!
