Perhaps it is ^^ I ain't much a LED specialist ^^ but i know some on the forum are a little more and i'm sure they'll know a little more about the subject ^^

The light maxx site is under construction, found some data from some of thier old lights RGB the blue and red bands are ok the green band is a waste of time.

The lenses were 120degrees which is fine for light washes or if the LED's are 5Watts or higher.

The lights I have seen were 1Watt and 3Watt chips so the lenses were to wide focus.

You also need a contoller to operate them,I also wonder how long they are designed to be used for, Continuous useage (18 hours a day) may be too much for them causing possible early failiure.

Most good LED grow light now have between 5-7 bands, more bands are available up to 11 band, this not really nescessary.

At some point in the future, more UV-B LED's will appear in grow lights and more lights may offer IR LED's to produce warmth, possibly thermostatically triggered.

Dual bands light work just not as efficiently as multiband lights, technology has advanced.

Single or dual band lights are good for helping out HID's and vegging, the RED for flowering and the BLUE for veg.

I love that people are trying to find ways of making the price cheaper by looking at lights not specifically designed for Growing, as Grow lights demand a higher price.

LED grow light are designed to do a job and to provide the light plants need in various stages of their growth, time and effort has been taken to provide what the plant needs.

So far no one has found the golden mean for LED lights, though they are pretty much there.

As soon as their site is up I will check what nm the LED chips are that they are using, the lens angle and chip Wattage.

Thanks for sharing your find with us. :)

Peace

Hi

I think that the green led are waste of time too but you can control every single led so if you put off all green the chip dont get to hot and the lifetimee is still 100.000 hrs and more. Also you safe the energy for the green led. The lights are tested for full time run and the max temperature is 45 °C (You can also get them as IP65 for outdoor use garden etc.) . The lenses in the Tri-led and Quad-led light are 25° plastic lenses. The Tri-led got RGB-Multchip, each color 1W. The Quad-led got RGBW-Multichip each color 2W. You dont need a controller cause at the back of the Lights is a stand alone display and few button to change the color. I got a few of them at home. If i got the time at the weekend or so i will open one and have a look what led are build in. I dont want to safe money but the ufos and other things dont look really professional to me. But why build by myself if I can get one in a testet product. I want to take 3 X 175W Quad-led Cans and compare it with a 600W room. If the time is right :(

Peace

Well i hope you will be able to test it and show it to us :) it will be some interestd grow to follow, for the 45°x3 it might give you some heat problem you will need to plan some good extraction i think ;)

have a good dy keep us updated ;)

guys do not know if I can be of help, I last year I bought a 600watt LED grow lamp from China directly, whereas the custom build you a chance to choose the number and power of the LEDs and the color tone I've chosen for my.

Blue 440 to 460 nm

orange 610 nm

660 nm red

180 Lm Warm White

The total cost including shipping and customs is $ 760 with a 2 year warranty, in fact after a few months I had a problem with a power supply, I immediately contacted the Chinese by providing photos of the fault has been sent to me again a power supply and 4 others I've bought a spare at a price of about $ 10 a factory.

So in my experience with the service is good and also the care, with a saving of almost 50% over the price of USA and EUROPE.

My lamp is composed of 12 to 350ma 50w power supplies, each power supply operates 48 LEDs mounted in series on a separate PCB, the pcd in turn rests on an attachable aluminum half an inch thick, which acts as a heatsink, cooled to its time by 12 pc fans, powered by 6 12v power supplies.

And remember that 99.9% of the LEDs on the market are produced in china.

Today I packed my 50 watt LED lamp, because I had placed in the greenhouse with the humidifier at the most and it was filled with water LoL, I had to disassemble it and dry it.

In fact I made ​​a small change and I placed the lamp on the outside.

I am posting a few pictures where you can see the lamp inside.

Thank Mykol:)

Some very useful information.

I wonder if you could answer a few questions.

1. Which company did you deal with, it is good to know that they have good customer care.

2. What wattage were the chips?

3. How did you 600W peform in a grow, do you have pics?

For anyone in the UK - $760 US Dollars is £479 GBP

Thats a great price for the Wattage.

Thanks for the pics and info on the 50W LED too.

Thanks for sharing

Peace

LAMS Hello, I'm sorry but I had a moment missed this topic.

but glad to answer.

1) I purchased Aliexspess the seller with whom I had to do is called'' the best supplier'' very serious and kind, almost every day you find it online, also a friend of mine has bought from this vendor a 300Watt LoL with 7-band ultraviolet and infrared (I thought it was a bit exaggerated, but everyone has their own tastes)

2) I opted for chips 1watt, right now it escapes me why, but before the purchase offettuare I did several searches on the leds I read somewhere that the chips were 1watt + performance than 3w and 2w, well My friend has been well documented on the LED before making the purchase and he too chose the chip 1watt.

but personally I've never done a comparison.

3) you have photos, but definitely not the way to really gauge the lamp.

I say this not because the light was definitely the cause of my failures hehehe

I can just load the.

Hey i did some research and i found out some interesting things in gerneral about LED Grow lights.

There are a lot of false-leading facts i stumbled onto. Please correct me if i understood anything wrong.

and it actually comes down to a few facts:

1. What kind of LED chip is the best for grow lights? 3-Watt give you most power. ( there are single dual and tripple chips eg. tripple chips has 3 litle 1-Watt led chips in 1 single LED. WE WANT SINGLE CHIP with 1 CHIP PER LED ARE THE BEST, the other models consum more energy have shorter life span and make more heat.(actually 1W is most energy efficient but 3w at 550mAH is only 5% less efficient but we want more power per m2 of lamp surface)

2. how much mAh the single 3Watt chip is given 500-550mAh should be best for longlife(the more mAh a chipe gets the brighter it is the hotter it gets and the faster it burns and breaks, remember this led technology is heat-destroyed if your led gets too hot it will loose brightness ! )

3. The manufacturing company of LED-Chips (e.g Osram, 3M, Epistar) choses for what 3w-led chip model for a specific nanometerwavelength in terms of efficiency ( some companies make verry good chips only for 1 or 2 wavelengths a growlight should contain LED chips from several BIG-LED manufacturers and only the best chips for the specific wavelengths the manufacturer is known to be best on the market for)

4. and what total wavespectrum is covered with what intensity in micromol/m2

5. The design of the lamps: I read about some lense systhems that fokus the light for best "penetration" (Hydro grow: pleds to have the best Lense system, but i have seen other models from china, that seem to have similar if not the same lens systhem)

if you want to combine everythin i just wrote here it somes down to a verry important Value that is the result of all this

PAR= the radiation only plants can use / need to grow ( photosynthetic radiation )

but even the PAR-Value is not completely significant.

the PAR-Spectrum ( that contains many singel wavelengths e.g. 660nm, 640nm...) also contains infrared- radiation also known as heat.

I think some of the wavelengths of the par spectrums also have a negative effect on plant growth so too much of a certain wavelength locks good on the total PAR value but might be actually bad for real-life performance of the light later.

UV-radiation (too much) is damaging the DNA of all organisms it causes burning of the plant leaves if too much

simple heat (infrared) is also in too much quantity verry bad. ( thats why we dont put the HPS too near to the plants. )(but there should be some uv radiation emitted from the grow light)

BUT unwanted/damaging heat increases the total PAR value because PAR = every single wavelength measured in photons (micro-moles) added together to the micro-moles of the whole PAR-Spectrum

Here a Video where if you stop and compare the LED model in the infrared nm-wavelength to the HPS the led has almost no infrared and the HPS has almost only infrared(way too much) but in the end HPS has a nice PAR value because of the infrared.

FUTURE: I think future developments will go to

1. Better-more efficient spectrum of par light and programmable light ( change of wavelengths during the plantlife, that stimulates budding better and makes the plant grow better maybe even simulate in a program the sunshine prifile of the prime locations in the world ( himalaya, marroko, nut maybe thats hype ;-) )

2. Special wavelengths to controll plant growth better: there are certain wavelengths that stimulate "shade" and actually makes tha plant grow taller so it will reach more light. I think this can be used to specifically let the smaller plants grow ore in length so the cannape is equally high.

I personally think at the moment "Hydro Grow" is the Number 1 Company is case of Lens systhems and maybe spectrum of growth light. I definately try to order a light from china that is most simillar to their penentrator Pro x model.

If only every company would give an accurate PAR-Value of their LED-Grow lights ;-(

If somebody can give me more information on Led lights PAR spectrum, i would be verry happy for your contribution.

Maybe we can customize and order our own Grow -Light if we find enough people to stem the money we can easily organize that, and push down the prize + worldwide shipping guess.

nice entry man, thanks for sharing your information on the LED's i'm sure it will be usefull to someone someday :)

I don't know more than that about PAR spectrum on led so can't help you sorry :)

I hope too that LED will be the future, and that prices will quickly go down as competition rises.

We'll be waiting, for the building can't afford that for the moment, but perhaps some will be interested

Have a good day

There are many companies producing the led lights an after using some of them i feel all are of the same caliber and there is not so much difference in all of them.

hmmm sounds good man, if you do make sure to show it to us ^^

Do you plant to integrate things like UV led in it too? that would be even nicer! :D

The sunpulse rotating thing was pretty cool and i'm pretty sure it's not hard top make a rotating system, with a fan motor maybe for example ^^

Good luck man

Hallo guys. nobody talk about phytoled???

They looks really good and u can buy many type of size.

i will buy the 280 w soon.

Looks really compact and they had all colors spectrum u need. im not a specialist sure. but from the research ive made. i think is very good.

Now price go down 20%. Hope will go down more!!

Site must be phytoled.com

bless everyone...

Kings.

Hi,

Personally i try and stay away from anything made in China. No offence, but it is all cheap rubbish. Even if the LED's are the same you will never be sure if the parts are fake.. I read somewhere that the US found loads of fake chinese computer chips on their military airplanes..

Anyway these are what i would say are the best...

QUANTUM Penetrator PRO or X4-G9 Stealth Bomber

They are ridiculously priced though...

About us

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
