Hey Bro That Coment Was for Al B Fucked No Worries I like cfls I sell them all day long just not what we use them for. This will be up dated almost daily, got to push the edge isn't that what brought about hydroponics in the first place This will be fun but no worries critisium is always welcome:bigjoint:
Thanks, please keep us updated and do a journal I really want to see how this turns out.

Here's my two cents...

I just ordered a UFO because of a big heat problem. I have a 3'x3'x6' tall flower room in which I'd been using a 250w HPS. I wanted to improve yield and thought it wouldn't be a big deal to change to a 400w HPS. That little change made a big difference in the temp; it shot up to almost a hundred degrees, in a basement, no less.

So I've ordered a UFO and it's supposed to be here tomorrow. I have one plant three weeks into flowering in there now. I guess I can offer to be a guinea pig and let you know how it goes. I was thinking about getting a UVB light too. I've heard there might be a benefit to that.

For 1800 bucks you can get 900 lumen son! 283 x 1w led is the FUTURE!

High Power LED Grow Lights from Sunshine Systems : The GrowPanel Pro LED grow light
Where did you obtain "900" from? Are you being sarcastic? Lumen doesn't mean a whole lot for a plant; we humans use it respectively to identify how bright an hps or mh would have to be for its use-able amount of light to be intense enough to activate and maintain photosynthesis.
ex.) A metal halide is actually brighter than an HPS to plants, but the HPS is rated with more lumen...

I rant too much, my apologies.

I sell lights for a living Your right led is new, but they only use 1/3 the electricity
wroooooooooooonnnnnnnnnnnng

A Luxeon K2 (which, by the way, you don't have, considering what you paid for yours) makes 200lm from 5W input. That's 40 lumens/watt. My 1000W HPS lamps make 160,000lm, or 160lm/W. My 1000HPS lamps are 4 times more efficient in lumens/watt than the very best LEDs (which, again, you don't have).

wronnnnnnnnnnng- high output LEDs make so much heat that they have to be flow soldered onto a heat dissipating mounting substrate! Their power supplies generate a fair amount of heat, too.

1/2 less water consumption,
Well, it makes sense that a plant that isn't thriving won't use much water... but I'd like to see where you got your figure from. It's a bit useless.

and only take up 1" of room.
Big deal, space is very cheap, especially space spent on lights that will produce some buds.

And 100% of the energy used is aburbed by the plant. 10% is about what is used by the plant with your hp5
Crap. Gimme a source for that information (that doesn't come from a maker or seller of LEDs).

So you are using 400 watts to get 40 watts worth of effect and a tracable amount of heat I will use for the enitre day the energy your 1000w wastes in heat and non-useable light in 1 hour, An Hp5 which must be cooled aswell.
Sorry, but this is bullshit.

your CFL's are loaded with Mercury:dunce: better hope one doesn't break, hope you recycle.
You SERIOUSLY don't wanna know about the cyanide and arsenic as well as lead & mercury used in the production of semiconductors. Look up gallium arsenide sometime- it's common in LEDs.
Leds last 100,000 hours what are you getting 600 hours tops. I sell photo lights for a living believe me when I tell you Led is the next generation of lights.
Oho, the truth comes out. You sell lights. No conflict of interest here, is there? :lol:

600 hours, my ass. My 400HPS in the mum area runs 8000 hours/year and my 1000HPS are running 4000h/yr.

Why do people come on this board and talk pure shit and think no one will call them out?

Lights Don't Smell Asshole:-P
Quite so! You need to use your nose to smell asshole. :lol:

They cost a massive bit; yeah, but, how many of ya have actually tried a proper LED grow?
How many people need to jump off a cliff to prove they can't fly? All you need to know is that LEDs make fuck-all luminous output to know they'll not be very good at growing plants.

For 1800 bucks you can get 900 lumen son! 283 x 1w led is the FUTURE!
For $1.50 you can get an 1800lm CFL at the fucking grocery.

You can take temp down with fans. I say go back to the hps.I talked with guys from htg about the led's they are only suppose to be used for supplimental light. Heat is always gonna be a factor If your in a closet I have a tiny grow box and just using cfl's I have to keep the door open until I can get better fans. Good luck with LED.

Wow you are an Angry Bitch :clap: Space = $, five miles from me the richest 1% of the world pay's $4000/ 1000 square ft per month, Arsinic etc wont leak out on my crop if I accidently hit the lights with my elbow or screw them in a notch too tight use the base to avoid this. I sell photo/ movie lights not grow lights, 140 watts all day 75 degress I'm the fucking source. If I turn your screws a little more I bet I could hear your head exploding from here And yes heres my source for the rest

Yeah, I do tend to get a bit snarky when people rock up here and spread the manure. It's hard enough for new growers to get good information without being deliberately misled.

edit: Going back and editing your post to include a bit of biased nonsense from a trade mag doesn't help your case.

You're perfectly entitled to fool yourself- you're NOT allowed to fool anyone else.

As I said later in the post, Al, I haven't done it myself either. I'm keepin' an open mind about them, is all. The rest of the info about LED's you threw up was helpful, as I didn't know that shit. My responses come from what I do know, which isn't much; not what I don't know. Responding with what I don't know would be making more of an ass out of myself then I already have, lol.

Oh, again for your reference though... lumen is a measurement relative to human sight. When grouping lumen with plants you have to take into account - they're plants. Thus to find how bright your hps actually is to a plant you would need to convert lumen to a plant relative measurement. What is it, PUR? plant use-able range.... or something like that.

I think I made a slight mistake in my logic. You would have to find out the % of PUR in your light then divide that by lumen or some kind of method to see how much of those 982354796245lumen the plant is using :P

I confused myself.......

Again, sorry for the rant.

I do not sell grow lights I sell movie lights the leds we sell are $1600.00 for 1 x 1 foot they are for shooting film and video the growing is a side hobby to keep me in pot so I can deal with the customers. but its fun when I get the address of the kid buying 5 85 watt cfls just squirms:fire:

One of the problems with keeping an open mind is that people will throw a lot of garbage in it. :D

Thus to find how bright your hps actually is to a plant you would need to convert lumen to a plant relative measurement. What is it, PUR? plant use-able range.... or something like that.

While the lumen figure is primarily based in human perception (as is the bel for sound), while plants don't see or perceive light, they do react to light within the visible spectrum. Not like these things photosynthesize on x-rays or magnetic flux or some other such thing which would be irrelevant to measurement with a unit of luminous intensity. The lumen thus a good figure for relative comparison of light sources.

It's pretty rich that the same jokers that claim lumens are useless for gauging what plants will do with the light will in the next breath quote that very lumen figure. All light producing products will have a luminous output rating, right down to 7-segment LEDs for numerical displays.

Plant usable radiation or similar figures allow you to split hairs fairly finely, but this much I can tell you, it's information that you just don't need to grow cannabis. It may allow you to argue a point but all you need to know to grow dope is that you need to flower with HPS to get good solid nugs.

I pride myself on being able to stay neutral, lol. I'm providing an argument for both sides, though shifted more towards LED's side (since this thread is about an LED grow heh)

I'm the young arrogant guy apparently, while you're the old goat who gets to me by shooting down much of what I say with even more refined intellect. Though you're most likely right about all of this stuff, I'll more than likely continue to brush off and forget most of what you say; just because.
(The last part was my attempt at a joke so subtle most people would take it seriously... so if you got it, I'm ruining it for you now! bleh)

My children are in their 20s & 30s and they hate me for all the same reasons. :lol: I'm totally OK with that because they can hate hate hate me now but take the wisdom with them for their own quiet benefit later.

You might be here for the LED thread, but I'm here for the cannabis growing forum. At the end of the day, what you most likely wanna do with information from RIU is grow some dope, not prove arcane points about whether lemmings really can live on squirrel fat alone.

Good point. My argument is now null, as you reminded me of the true nature of the forum.

Zat, I never had a gripe with anyone, not even the lighting seller who is utterly convinced that the light that shines out of The Almighty's Arse comes from LEDs. You'll notice I haven't had to call anyone names, impugn their intelligence, etc. I go straight after bad information and hold it up as such, which is sufficient. The people, being anonymous, are largely irrelevant.

Indeed, the end game is growing buds. I've been asked countless times to write a grow book. I am very confident I can do it in 10 pages or less, if all I have to cover is the stuff that will grow dope for anyone, first time.
