la9 u have no experience with the ufo so u dont know whether a 70w hps would out do it.. y dont u stop baggin on the ufo and just help with advice on how to improve the set up not take away from it

I have electronic experience and know well enough about LED's to help everyone make the right decision.

If you are so sure a UFO can beat a 70 watt HPS we can put some money on it, because I don't think it can myself.

I have tried to help, I've put on several threads that anyone wanting to spend $600 on an LED light I will design one with better specs than a UFO for the same price and no takers. I am trying to help.

I offered a 70 watt HPS for an independant grow for comparison, I am trying to help.

What have you done to help except say I don't know what I'm talking about ?

i completely agree that someone in the situation of buying a new light should absolutely go with a hps...i had a certain financial comeup so the light was of no cost to me..and the reason i said that was that in my situation i want to add not take away and all u did on the thread was bag on the light..thanks for ur input but bag the ufo somewhere else please

Look I done went and made him cranky....Bwahahaha

we told him it was a joke and he is still trying to compare his wonderlight to it. How bad is that ?

My LED light is better than your joke.

Keep going little man, you are funny.

They aren't looking bad, but they sure are stretched. Usually a sign of not enough light honestly. I have also been VERY interested in learning about the leds, and seeing if they work. I've been thinking about getting one just for my mother plants, I have a 1000w hps for the growing. If you just got the 2 150w hps, then I would figure out your ventalation tomarrow, and put up the hps. The plants should fill out, and stop stretching, they are still young! Take a look at this plant, they only have one, but they have tons of light. The plant is tiny, for being a month old, but it is super bushy which is most likly from the lights being used. https://www.rollitup.org/newbie-central/115216-how-often-should-i-water.html I hope it keeps going well, keep us posted, keep growing!

If you want something for a mother plant just get a couple normal wattage CFL's or a metal halide around 175 watts.

2-23 watt CFL's will be enough to keep one plant alive.

That was another option that I have been considering, I don'thave anything going indoors right now. I may go with the cfls, but I'm always open to seeing how somthing new works. The cfl's would obviously be a cheap option, so that may be what happens. I didn't pay for my hps, I'm deffinatly on a budget.

Don't say cheaper since you can get a 150 watt HPS for $20, I think $32 shipped or if you had a couple CFL's laying around the house go ahead and use them. Hope that didn't make it harder to decide again.

i had the light up too high and still possibly do..but due to how many plants i have in there the light needs to b higher to spread to the others...when i moved the light lower i saw a couple begin to bend to the light so i had to move my biggest ones to the side and let the sprouts get the main light...the UFO shoots directly down so it would be ideal for growing 2 mother plants and would actualy impress u most likely

I'll have to see what route looks best, and I can afford. Did you get those 2 150's up yet? If you have them dude I would start using them asap, and that will help with not having enough light to properly cover all of them. The 2 150's will give you more light then that link I left for you, they only have 250. Then you add in what the ufo has to offer you'll and I GAURENTEE you will see a huge growth differance. Just keep them watered once you do!!

The problem with LEDs is simply that they lack light intensity. Let's say that the light intensity is 3600 lumens (that appears to be the case), and all of that light intensity is confined to the spectrum that plants need. Okay, at 1 inch, it's 3600 lumens. So, since light decreases with the square of the distance from the source, at 2 inches it'll be 900 lumens, at 3 inches it'll be 400 lumens, at 4 inches it'll be a bit over 200 lumens, at 5 inches it'll be around 144 lumens, at 6 inches it'll be 100 lumens (1/36th of the original intensity), and so on.

So, basically, if you can't keep the light within a couple of inches of the plants, you're losing so much intensity that the plants stretch. That's not so bad during veg, because the plants are shorter. In flowering though, one bud can be 8 inches long all by itself, so while the top of the bud might get enough light, the rest of it will not. Net result: very low yield.

As a super-expensive veg light, they seem alright. Until they come waaaay down in price (or waaaaay up in light intensity), they're not suitable for flowering though.

What he said they just aren't worth it right now. Those LED's in the UFO are only putting out about 45 lumens. Compare that to a HPS listed at 50,000. That is only about 49,955 lumens difference, if it looks that big on paper what do you think the plants think ?

Next you will hear they are in the color spectrum so it doesn't matter, guess what, the HPS is in the right color spectrum also, so it does matter.

Unless you have money to burn, in which case I take donations, or you are growing on the space shuttle and every atom of electric counts just save your money.

Check it again. That ain't the way it works! The Inverse Square Law (which you are refering to) is only applicable to "Point Light Sources" - LED's are directional and, therefore, subject to an entirely different formula for figuring how much light energy you lose for each given amount of distance. A "Point Light Source", theorhetically, radiates a full 360 degrees in all directions (up, down, sideways, everywhich way!) - much like any type of light bulb that doesn't have a built in reflector to "direct" the initial flow of photons. Like a spotlight, for example. A spotlight has a built in reflector so it's not a "point light source".

LED's and other "directional" sources of light diminish in power in proportion to thier angle of projection - not in accordence with The Inverse Square Law!!!

In earlier posts I read several people suggesting that the UFO should be "Moved closer to the plant". And the OP said "it doesn't spread out that much so I have to keep it farther away" - that's true and it's okay!!! Since LED's don't lose thier light energy anywhere near as easily (distencewise) as regular lights, it's ok to have them further away. In fact most LED grow light manufacterers advise growers to keep an 18"-24" spread, as I recall. Most LED's produce a rather narrow beam, many only about 15-20 degrees - that is why their light can still be effective at a greater distence

Well, I have a friend who spent a couple of grand on some LED lights. He tried to use them for flowering, and the results were laughable. Not saying you can't do it though -- I wish you the best of luck! Having seen the results, I have zero interest myself, at least not yet. Maybe 5 years from now they'll be a bit more viable for flowering.

And sure, I understand what you're saying. My HPS lights are also, with a reflector, directional light sources. 95,000 lumens of plant-optimized spectrum is simply better than 3,600 lumens of plant-optimized spectrum. But if it works for you, more power to ya. It's not my money or my buds, so what do I care?

finally someone understands the light shoots straight down!!!!and for hps lights they come on the 6th

Cutting and pasting information from UFO LED Growlight website sure is understanding isn't it ?

All anyone needs to understand is HPS and Metal Halide all the way.

They will have the best plants ever.

LED and they will be greatly disappointed.

a 125w envirolite is far better at vegging than this ufo ,they come in exactly the right coulor /PAR for the two different growing phases and cost a fraction of the price , you can also get 200w and 250w bulbs aswell .i also hear that they are bringing out a monster 400w envirolite out soon ,i cant wait .

Are you really trying to convince us that a 125 watt CFL will beat a 45 lumen UFO Light ? :smile: HAHAHAHAHAHAAHA

All you need to do is go to Youtube and watch side by side trials of UFO and HID to see the difference. Don't fall for the hype that people with a personal stake in sales of UFO's might have.
