Does anyone no anything about those ufo led light and if there worth a shit????


ive heard negative and positive dont no what to believe!:wall:

They don't use much electricity, that's the biggest pro I would mention. Cons, now light penetration.

denser buds or a cheaper electricity bill, you decide

i would use an LED panel if I grew in an oven.

Its actually a myth that LED's don't produce dense buds. There are some medical dispensaries that grow exclusively with LED's for the quality of buds they produce. Where you need to watch out is when you're sorting through manufacturer claims and all the other nonsense out there. For example, some manufacturers will tell you a 90W UFO = 400W HID. This is not true. I'd be more inclined to say two 90W UFO's are equal to a 400W HID. So to sum things up, they are worth switching to in my opinion. I'm a very satisfied LED user. Just do your research before you buy anything.

I also forgot, its a myth that LED's don't produce heat. The actual diodes themselves don't, but the circuitry that powers them does. It's a lot less heat than any HID's produce though, my growlab hasn't seen a temp over 84 degrees.

If you have some links to back up these "myths" I would love to see them.

You're never going to get the lumen output / penetration that you would from an HPS/MH. Period.

Okay I was bored and did some searching.

90w 3800 lumens: http://www.ledlightsorient.com/90w-ufo-led-grow-lights-lgl0505-p-10.html
90w 3200 lumens: http://www.ledgrowlightsoutlet.com/90-w-ufo-led-grow-lights.html

Both of those give different lumen numbers. I think it's funny cause I have a 42w CFL bulb from Menards that costs $10 that gives out 4600 lumens. Which means it's also more efficient in terms of lumen per watt output.

Compare that to an HPS
600w 90,000 lumens: http://www.1000bulbs.com/product/4984/LU0600-0600T15.html
400w 55,000 lumens: http://www.amazon.com/400w-HPS-Hortilux-Bulb-Pressure/dp/B000BZ98BQ

I really hope okcomputer didn't buy that light system that costs over $1000 I could have bought 3 1000w bulbs for that price with change to spare

There is absolutely nothing I said that requires backing up. These are things I learned while growing with LED's. Nowhere did I say I will get the lumen output that I would from an HID. When growing with LED's, lumen output is not what matters, its PAR. Someone had questions regarding LED's and it's pretty obvious that you have a strong bias against them. Maybe this isn't the best thread for you to respond to since you don't use LED's and can't offer any useful advice about them. Don't make this into an LED vs HID battle.

HPS is definitely more worth it if you're thinking about input costs; they're not that expensive and they will definitely produce a decent harvest. If heat or power bill is your biggest concern, go for the LED.

I'm not biased, it's common sense. You have a strong bias towards LED's, yet it's funny how you think you are giving useful advice. The light is your best investment in a grow, and high lumen output is the most important, even besides color spectrum. I love how you say lumens don't matter. Have fun growing air buds.

Like I said before, lumens don't matter to plants. Lumens are a way of measuring the amount of light humans can see. PAR is a measure of actual light that plants use in photosynthesis. Even an HPS lamp has its spectral analysis given in PAR. You are right when you say I am biased towards LED's though. I have grown with HID's and I prefer the LED unit.

So basically the HPS light gives the plants a lower PAR numbered compared to an LED, and thus LED's produce denser nugs?

I'm not saying they produce denser nugs, but they are very capable of growing equal quality buds. What I am saying, is although the lumen output is lower, this is made up for by outputting more light in the proper PAR spectrum that the plants need to grow. A lot of this light is not visible to the human eye, thus the low lumen output.

I just hope the op doesn't fall for this. You keep bringing up the low lumen output but high PAR, but what about penetration? As I said, air buds.

Please don't give misinformation to someone looking for advice on LED's. More lumens, bigger plants, bigger harvest. None of this PAR nonsense.

Good luck with your grow though.

This is not misinformation. Plants don't care if your light has one hundred or one million lumens. What matters is how much of that light is PAR, or photosynthetically active radiation. What you're looking for is readings between 400 and 700nm for full spectrum lighting. This is where LED's excel; all of the light is within this range so the plant gets more usable light with less wasted energy.

He's right about PAR.

Some people don't want to deal with excessive heat and exploding bulbs. And dude you just started growing and bought a brand new 1000w. I think you're just in love with your light. Some people have different reasons for growing... and many people grow just for themselves I personally think LEDs are very convenient in terms of heat and safety. Not everyone wants to have a 3000W HPS harvest every week type of deal
