Led lamp test! 1 week!

[tonttu]

Hi,
This LED stuff really picks my intrest... I am a fan of HPS they bring the light to my winters :-P
But of course electric bill is something awful.

My friends audio company uses these LED spots http://www.thomann.de/fi/stairville_led_par_56_10_mm_black_rgb.htm
So those can be adjusted ammount of red, green and blue. I am not saying that its as good as those expencive ones, but considering the price of 49e that is definetly something worth trying.

I have seen those in action and I assure you those produce lots of lumens...

Tell me what u think of my idea :-)

[CyberDog]

I was thinking those kind of lamps also. I would order and test if I even got that little spare money...

[AlexChupetinho]

It would be interesting to know which wavelength the light of those LEDs have.
It should be about of 460nm for growing and about 630-660nm for flowering. It is said this wavelengths are optimal for plants.
LEDs with other wavelengths of the light would have little to no effect, even if power LEDs!

Anyway, I'm very interested in the results of your testings

Emitters should provide light at 460nm, 630nm & 660nm. Most likely they use the same emitter mix in this LED like the others. 20% 460nm, 40% 630nm & 40nm 660nm.

630nm emitters are cheaper than 660nm emitters.

This one should have 1W emitters, 90pcs of them.

How big grow space do you think, that this stuff is capable to light up? thanks

Hi Herpiili,
well, I meant this one http://www.thomann.de/fi/stairville_led_par_56_10_mm_black_rgb.htm
(indicated by tonttu). It costs 49, euros. I thought you want to check it.

You speak about the so called "UFO Grow lamp"  Well, I know, it seems to make wonders but it's to expensive for the moment!   

[Fatalii]

I'm currently test driving UFO lamp with lettuce... really does the work nicely.
So I'm very happy with the results both for producing fruits (chiles)and growing leaf mass (lettuce).

[talas]

Yes getting more impressed myself the more i hear/Read about these..

[AlexChupetinho]

I'll definitely buy that damned UFO!!!
How many sq meter can cover such an UFO?
--

[talas]

18 square feet ive seen quoted,Like to see what Fatalii has to say about that though 

[AlexChupetinho]

18 sq feet is about 1,6 sq meter, that is a square having a side of 1,2 meter. pretty good!

[Fatalii]

Sounds actually kinda little to me

Of course, If you want to make your plants flower a lot, thats sounds quite reasonable, but at growing stage, or growing lettuce and herbs it may cover ever a larger area.

I'm quite amazed how far it can far away plants can be lighted with it.

It's very good to move flowering plants closer and the ones that need to grow some foliage can be further away.
At least works very well with Bonchi plants!

Well, Fatalii, it's kinda little for you but remember I'm a hobby Chile grower so a bit more then one sq meter is very good for me! 
As I wrote earlier I've contacted one of hte Chinese companys producing these UFOs. The sales representative told me the price an asked me how many blue and how many red/blue LEDs I want in my lamp. I said I want to think about and didn't communicate with him anymore, but I guess they can produce grow lamps as well as flowering ones. I'll wait until the price (including all taxes and transportation fees) drops to 150 euro. Then I think about buying 2 lamps: the one blue and the other one like yours.

[tadytomas]

do somebody have an experience with cheaper UFO (China etc) which are available on Ebay.uk? They are about 120 pounds for a piece.

to Fatalii: can you gime me some link, where did you buy yours UFO, to compare the LEDs in it.. thanks

[tadytomas]

well, what do you think about this?

the WaveLength are the same, as in yours.. but the price is much lower..

[AlexChupetinho]

well, tadytomas, it seems to be the same lamp. The producers of this UFOs - and more types of LED lamps - are located in China.
They produce LED panels as well. The core of this lamps are the power LEDs they manufacture. The LEDs seem all to be the same 1 Watt.

They say, a 100W led panel is equivalent to 400W HPS/MH lamp.

Have a look at this:

I think, and of this year we'll be able to buy an UFO with 100 euros!

I hope so.. 

[Fatalii]

You just have to keep in mind that higher price is reasoned when you think about much lower  power consumption compared to HPS and Metal halide.
The prices will definitely come down even for the best LEDs but I think it would be much wiser to check how much you will save with the electricity cost first.

And beware of the spot leds, those won't give you any good results!

[chiliumi]

Hello, and greetings to all since this is my first post here
I was wondering what kind of results do you get with lets say 400W HPS on those bonchis? How much heat does that UFO produce?
