A couple of questions . I have 2 1000 watt full spectrum led grow lights is this enough for a tent this size ? Would smaller watt leds be better 300 - 600 and how many ? I want big buds but need to be economical as well .
Thx
Can you post the model number or specs for the lights you are referring to?
For example, I have a pair of “1500w” blurple LEDs that actually draw 260w from the wall each, and actually adequately flower about six square feet each.
Two of them (520w total) did a solid job flowering out a 4x4 tent (16 square feet). You are looking at more like 40 square feet to cover. So, with my “1500w” LEDs, I’d probably want something like 4-8 of them for flower.
Once you do the math on the amount of light you truly need, then you can figure out how to budget for it.

isn’t 65 wattper with led’s (4by4=16 x 65 = 1,050) Yes; it will work but need to get your distances in veg and flower ?
Coverage Area: Core Coverage area at 42"42"(3.53.5ft). Maximum coverage area at 65"65"(5.55.5ft) Manufacturer says 24 In. Plant is about 20 in. from it now flowering . Thank you for your response . I think the plant is about as tall as it will get .

I try to hold at least 18 to 24 in but as you can see I posted the link where I purchased the lights you guys can see the specs .
Thx again
This is my very first grow 
. Been growing since the 2nd week of September .
what strain ? grew a Blue Dream - flipped it at 21 inches and the plant got 7 feet tall ----maybe considering flip ?

Does it say it uses Bridgelux leds? I glanced, didn’t see anywhere. I’m not aware of bridgelux releasing any leds like that. It’s possible a third party reflows them onto chip package like that. But they seem in line with just about everything else using epistar leds.
flower time 10 weeks ?
3rd week of flowering .
Yeah that’s what it said on the Amazon entry:

Your eye better than mine, I have no idea which ones they may be using. I went t8 their product application page yesterday, looked like only stuff they had under horticulture application was V series and Vero cobs.
@Glokin - ideally when determining our grow lights it is important to consider how much actual light is produced by the fixtures. A “high end” (read: good) LED manufacturer will give you this data, usually in the form of “ppf.” Sometimes they will provide a “PAR map” which shows the ppf at some specific distance under the light.
PAR stands for photo-synthetically activated radiation, and represents the light spectrum that are used for photosynthesis. Hence the reason we have blurple LEDs. Basically PAR just tells just the type of light our plants need/want/prefer.
PPF stands for photosynthetic photon flux and it represents the amount of PAR that the fixture can produce every second.
Generally with those two metrics we can determine what kind and how much of a light fixture is needed for the space that needs to be lit.
The reason I asked @dbrn32 if he knew which Bridgelux LEDs are used in your fixtures is because I wanted to see if we could find the specifications for the specific diodes in your lights, since I was completely unable to find any actual output data online. As a result, all we really know at this point is that you have light fixtures that have one hundred fifteen watt (supposedly) LEDs that consume 180w as they are currently driven. So that’s 1.8w per diode, when in fact they can be run at 15w (supposedly).
We will need to find more data on the diodes and/or fixtures to determine how many you’d need for your space, but if we assume they are on par with other blurple fixtures you find on Amazon, then in general you should try to get to 50w per square foot of actual power consumption using the blurple panels.

I’m a little jammed up at work for a bit this morning. But i would figure the fixture in question would be in line with the rest of amazon blurples.
