what is your favorite led light???

[tyler_ hobbyist]

I am looking to exspand my grow area. I am looking for sugestions on LED lights. The price has to be resonable. I currently love the 1000w bestva LED for under 150bucks

[yamiacaveman]

I got two led, cheap chinese lights, full spectrum, they say 300 watts, 5watt led x 60, all I can tell you on that so far so good.
I also use a couple of these with cfl's mostly but sometimes led's.

[tyler_ hobbyist]

Do u know the name? And we're to get it?

[yamiacaveman]

Well they are only 132 watt -- https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

[Flockshot]

1000w LED for under $150. Just get another one of those.

[tyler_ hobbyist]

What led do you use flockshot?

[Gordo41]

Sorry guys but wattage Is not a good indication of light output. A lot of power (watts) can be lost as HEAT. Even measuring light output by lumons or lux can be misleading when it comes to how much light a plant can use. As far as I know, the best indicator of a lights ability to furnish the kind of light a plant can use is the PAR rating.
this is the amount of light the plant can actually use. Look it up.

[tyler_ hobbyist]

Agree with u 100 percent but what does that have to do with the post? U can even break the light a plant needs down to umole/moles as well par value will only tell u the strength of the spectrum of your light. What kinda LED light do you like to use?

[Gordo41]

Well, it has to do with the references to wattage that the guys are talking about 1000w for X $, my point was DON"T go by wattage at all. But to answer your question,,, I'm using a Cree 3590 COB 50w with a PAR of 1050 @16". Actually I have a 5 light setup.
I'll post a pic below.

Love your new setup, Gordo. Keep us posted during flower!

[Sonnyhad]

Nice cob setup

[Soilscience]

Yes. That's the real deal. I just started building these. Huge difference between this and an Amazon "COB", or led.

[tyler_ hobbyist]

That's a nice looking light why is the spectrum more like 2700k?

[Gordo41]

It's actually 3500k but has a lot of blue light spectrom in it, so it can be used for veg also. I have 2 autos under it right now in veg and they seem to be doing very well. When they get to the flower stage there will be tons of light for them to use.
I did a lot of soul searching before I bit the bullet on these lights. I had Mars leds before this. Which in my opinion are crap compaired to these.

[Soilscience]

Doing test right now on Vero COB. 3000 vs. 3500. The 35k is producing heavier flowers with more trichomes. I think they both have similar reds, but the 35 has more blue and less yellow.

[Gordo41]

This light setup has a dimmer on it which lets me dile in any amount of light I choose. Here iI have it set at 40,000 lux for the veg cycle.
You can see the blue at this setting.

[tyler_ hobbyist]

That's a nice set up sweet that it has a dimmer switch as well

Gordo poses a very valid question....how does wattage 'specs' correlate to actual photo energy the plant can use.
Unfortunately, on most that you see online it has very little connection. For an absolute minimum I would like to see at least 25 actual watt/ square foot -50 would be better. Most of the lamps like Mars or Vipar spec bloated wattage ratting but when they do offer some PAR or PPFD specs they are pretty puny compared to what is really out there. Gordo's rig is very similar to what I use-2 four lamp arrays over an 8 plant grow room. They will pump out over 650W when needed but I can dim them when penetration isn't needed. I've got right at $650 in materials for both arrays. Makes a HUGE difference in the grow.

[tyler_ hobbyist]

So what are some brand names and par values that are out there?

[tyler_ hobbyist]

Par rateing is the way to go but when looking to buy a light 90 percent of the time the title of the light wount say in par value it will say watts. For example (bestva 1000w) (vipaspectra1200w) mars300w ect... most people wount come out and tell u how much par there light gets they just say wattage, so then if I can can atleast get a name and wattage I could look up the par value so I know how strong it is. It doesn't matter if it hps mh led all fixures are made different.

[tyler_ hobbyist]

Watts is the mostly used reference to any light fixture for growing

[tyler_ hobbyist]

Not all (1000watt) or any other watt for that matter hps/mh bulbs have the same par value, same as LED. But most people dnt know there true par value is of there lights so they use wattage that's an easyier way for me to find a new light

[tyler_ hobbyist]

Yes PAR is what the plants actualy use for energy but the reason people dnt use par value is because in the coverage area the par value is not the same and in some cases it can be off by hundred's of pars in the same coverage area. This is why people use lumens or watts.
