I did not see it like this, For me when XTE is 3000K it's 3000K and if you get a bin T3 or T2 there is no difference in spectrum but only in quantity of photons... well I might need to look at you interesting statements :) But anyway I was more going on the question of lenses... I still don't...

I think you mix some stuffs Spheda. I don't pretend I am saying truth, but this is what I got from my lectures and understandings: 3000K is the color, it indicates either if he white is Warm or cold; from this you can get an idea of the quantity of red and of blue inside. 2700K has more red...

You know, Spheda, XTE top bin are 3,25$ (not sure because I remember in euro) and you can choose you ratio, spread the light evrywhere and make a better cooling than 10led on a 5x5area. With the light you show us, the only great thing is the price Which is 7$less, but if the bin are shitty...

thank you JMD :) I have mixed feeling about these light: -we don't know the bin, sometime cree with bad bin are not efficient at all... -we can not choose the spectrum, I mean it will be completely white or blue/red or WW but not mixed. and if you put many of them the color will not mix unless...

Hello everyone, There is something I didn't get: Everyone told me don't go for 1W, but what about ASTIR panel? even SDS said nothing. By wanting to "copy" the Apache with a spectrum closer to Area51. I am just doing an Astir panel with customized spectrum and some lenses... Then I wonder What...

Thanks very much Puff for this nice and precise answer. :)

hi tags, Yeah XTE sound good. the only thing I prefer with XML2 is the wide spectrum, the great efficiency and also I need to do less work. It seems I can either go for 1 XML2 WW bin T5 3000K + 1 WML2 CW bin T6 65000K @2000mA or a bit more. And 2 XPE2 red 630nm @900mA It looks pretty much like...

Hello, sorry petflora I was obviously meaning 640-650 and not 440. stupid mistake. Only 72lum/W at 1000mA? I don't get it. if it's 12V then MKR are better if my memroy is not at falt they get about 90lumen/W @1A but twice more expensive if it 6V then I never saw this XML but the XML2 3000K bin...

Hi everyone, Thank for helping me :) First I agree XML WW in U2 bin is very suspicious I have always seen some S6 and T3 bin for 10$ the chip. Then I had a little thought on this MKR: I am in france, hence I can not import from many different suppliers otherwise the addition with huge shipping...

hum... then you are lossing me... what's point of calculating some stuff if you know it's bullshit? So satisled make led but we know nothing of it. they can actually put less than 500mW no one would no it... I love the oslon 660, but their prices is too expensive. I will probably go with it...

Yeah your right I did a mistake, I check the cree XTE today, from cutter, my memory is not very good.^^ by the way even if I am going with XTE WW, I saw that 3W led from satisled are 200-220lumens. But I can not compare it because of the spectrum, and don't even have the datasheets. Clearly I...

Petflora LOL, yes I did bulge... I already saw it. I like what you are doing with your bulbs. :) So for you XTE WW 3000K will bring all the 630 needed? of what I red, 630 will make the bud growing and longer. when you add 660 the bud stop growing but its density increase and its maturity come...

Thanks for encouragements !! :) well I beg everything will be fine...

SDS I thought will not come... I asked you some questions on your WW 4 ever and I didn't had answer. Any way I am glad You came, because I do love your interventions. What is the actual ratio you use? your plants are beautiful indeed. Also I notice the penetration with 80° angle is very good...

Thank you very much lax123. you helped me a lot. I am not a newbie grower in fact, I am just new on this forum, but I have a bit of skills under 250W HPS and outdoor growing. In my area the summer is hot sometimes more than 40°C so inside is aboute 30°C, I am growing in a small cab and I just...

The same as you, what is strange is that I did not find the same thing... I had 782mW. So I must have done a mistake. Sorry But oslon SSL are not 864mW but something like 950mW and they also can be driven at 1000mA instead of 700mA which is quite interesting if you go with XTE. edit: wait a...

Skyled: I didn't say that but I can understand what he means I think: I thought when you compare two led of approximately the same spectrum, lumens can be taken into account. I am comparing a oslon which has a wide spectrum tending towards 645nm so it will get more lumens than a simple led...

thanks you tags420 for information. I saw your journal, I loved the videos you did ;) Then I can understand why AT has such efficiency. in my case my ratio white red is 5:2 Just want to make sure you understand me well here : I am hesitating between using chepo led from satisled or using...

thanks everyone for answering to me :) well I think you misundersttod my spectrum, I may not be clear (english is not my mother toungue). I will go with white and red that's for sure, but my ratio will not be 1/1. I will have a 1:1 ratio for my red 660:630 On my first intention I was going to...

Hello everyone, I have to say your grow journal is impressive puff, I am a bit sad I discovered it only today but any way I will follow it from now on. You already have huge colas, well done! I wanted to ask you: how far is you apache from the plants? I will probably make my own apache with 1W...
