How many watts for a 2x4 growspace

[Newbie27]

I've been involved in many of those discussions. They are all over this board. lol. Do a search ... you will find them. If money isn't the issue, purchase something you will be happy with. I think the Amazon light you are interested in would end up being a disappointment to you.

AND

Personally, I would go with 320watts of light from the wall in a 2 x 4. It's a bit over-kill so be sure to get a light that has a dimmer.

Its a 240 from the wall thats the wattage for a 2x4 tent

It's NOT pulling 1500watts from the wall. That's an advertising ploy and you're buying into it. Find out exactly what wattage it's pulling from the wall.

Its pulling 240 FROM THE WALLL IT SAYS IT IN THE PICTURE MAN READ!!!!!

YOU THOUGHT I THOUGHT IT WAS ACTUALLY 1500 WATTS

"1500w(5pcs 300w integrated COB leds) light just consumes about 270W power"

Yea i kno but which is better for a 2x4 one priced at 240 watts for $170
Or one that produces 240 watts for $80 even if i get 2 of the $80 it would be more watts more coverage ect every led light produces heat spider farmer led produces heat as well as mars hydro you have to ventilate the tent thats all in my book but hey imma newbie so not much experience here!

Stop fixating on the wattage!! Watts measure how much energy a light uses, not how much light is produced. Light isn't measured in watts. It's measured in foot-candles or lumens (and for grow lights often show as PAR/PPFD). You can just connect a piece of metal to a couple wires if you just want to use up a bunch of watts. High wattage doesn’t equate to a good light, it could just be very inefficient. Almost assuredly if the manufacturer isn’t telling you the brand name of the LEDs and driver, the light is a POS.

270 watts includes the fan ...

270 watts includes the fan ...

Those fans are usually 5w each so it's 260w total for 150 diodes.

Exactly

PERFECT FOR A 2X4 THERES NOTHING U CAN SAY RONG ABOUT THIS LIGHT I UNDERSTAND YOUVE BEEN TOLD YOU HAVE TO

Par is intensity correct?

THANK YOU!

OK, do what you want. Remember, I've built the same style light. I replaced it and I'm glad I did.

Peace ....

About PAR, PPF, And PPFD

If you're shopping for horticulture grow lights, you may have seen the terms watts, lumens, LUX, foot candles, PAR, PPF, PPFD, and photon efficiency.

With 260w of LED within a less than a half a foot of each other, you'll basically be getting hps numbers. Low efficiency, high temperature.
Plus, if you look at the spectrum it has too much blue. At least for my liking.

It was a simple question sir lol

The cooler LEDs are, the better they run.

And i was thinking of getting 2 for a 2x4

Your answer is no, the question is simple, the answer isn't.

 

[Newbie27]

The cooler LEDs are, the better they run.

So all i have to do is have good ventilation correct?
But what makes it low efficiency?
