Free speech goes both ways even if you dont like what is being said and so far Mello has free speeched you into looking like a fool.
I have scoured the MKR datasheets and I cannot figure out how Cree came up with that figure. Seems there was a misunderstanding in the press release. The best I have got my hands on so far is the XM-L2 U2 4350K which is 172lm/W @350mA Tj50C and cost $4.63/W. The U3 bin is available but it is 6300K.
). It is running at 300mA, Tj 30C creating >180 lm/W. It was supposed to be 4350K but it seems cooler to me (color temp in the pic is off a bit). I like 4000K for kitchen/bathroom/headlamps/outdoor lighting
So can u please tell me how has he made a fool out of me. He hasn't been able to prove anything but still trying. I gues EH from A51 don't know what he's talking about when he agreed with me. But yet, I'm still putting up with all this crap just to hopefully sell some panels here and make how much? U guys are nuts, seriously I don't know what else to say. Like I said, u can challenge me all u want but the truth, the truth. It's all there and spelled out. Convenient or not. I have nothing to hide and can't believe we're sitting here still questioning if I was still here pitching panels. You guys are unreal. All this for a few panels and u can come up with this conclusion. I guess that with the people who came forward stating their cheap factory panels are servicing them just fine. What the hell is wrong with giving people multiple options since the price difference can be dramatic in this business and not everyone has the funds for these brand names. I do have photos and have posted them on other threads but have been busy dealing with all these bs attacks.
I tried. The plants tell me to do things.I have an idea.....Everyone go tend to your plantz.....
Well MC they probably gonna say you Photoshop that ... Better go get the blood test done....
Well I have been running test for almost three years using name brand LED and factory direct LED. I took them a part and down to they way they were constructed to all of the part numbers on each component they were the same. I have grown the exact same strains (clones from the mother under all three different light conditions). CFL, LED, and HID. If you have insufficient light, incorrect temperatures, you can get a plant to stretch. Since I have no personal experience with the A51 I cannot comment on them and won't.
You're right, reds are needed for veg. just not as much especially the 630's. The 660nm and far reds are more for flowering. You'll be fine as long as u have enough blues, especially 470nm which is the most readily absorb blues. This thing bout they don't need any reds makes no sense as they need the whole complete spectrum not just the peaks as targeted the the red spec. I guess during spring there's no reds in sunlight for some reason according to man and the so-called experts. The red spectrum is slowly becoming obsolete as the market has finally got the idea that Apache has been doing since it's introduction. They are responsible for the application of whites, particular cool-whites since it's the most efficient and peaks in the blue/green that's ideal for canopy penetration. They use 630nm to supplement the shortage of reds in the cool-whites(6000-6500k). The 630's also the most readily absorb reds as this is why both Apache/A51 chose to use exclusively.
Yeah, I know. I'm desperate enough to doctored up 3 separate companies, not just one to look better. lol. Yeah, I'm just a chump pitching cheap panels and never used a so-called brand-name panels before since those cards are photoshoped so I don't think I can afford those high-priced quality american sold, chinese-made panels. And somehow American workers can do a better job of assembling. Guess those Chinese workers' are not capable of assembling low-tech led panels but they can build your Iphones. Maan, gotta hand to the industry as a whole as they seem to still have everyone thinking factory-direct are crap so they can turn around and sell u the exact panel for 3-4x the price, but hey it's ok, they're American companies and would never think bout ripping u off. lol. At least the chinese are fair/realistic in their pricing that the us based companies if they give a damn bout us, they would pass some of those savings to us. This greed is a detriment to the new or limited budget consumers that seems to be forgotten by threads like these because it's more cool to talk bout expensive bells and whistles instead of hardware that actually grow meds. As I said, at the end of the day, no one gives a rats rear-end what and how much u paid, only yield and quality and that requires correct spec. and most important the power/intensity. Without this, you will end up with airy buds with no mass no matter what said since physics will dictate actual results not bs claims snf bells & whistles. I guess I'll just believe and rely on whatever the companies market and rely on their expertise and integrity to ensure that I'm getting the most for my money. Another option for us is to be the ideal poster child consumer and buy/pay anything they ask for and always just the company or person trying to sell u something. Yeah, this is exactly the purpose for people to come to these threads to learn how to be rip-off. lol. But hey, I don't know squat as I'm just trying to pitch a few panels and make a few bucks for dinner otherwise why would someone put up with this kind of mentality. But then again, all the people who has come forward including A51 stating the chinese panels works fine and some of them actually can outperform some of the top brands means nothing cause they're just cheap factory panels that we pay a fair price for.
Well that makes sense friend................cause I also was never able to find that(200lm/w) output outside of the cree press release. If their cobs keep the improving at the current efficacy rates, it maybe a no-brainer on which way we'll go for the $$/wattI have scoured the MKR datasheets and I cannot figure out how Cree came up with that figure. Seems there was a misunderstanding in the press release. The best I have got my hands on so far is the XM-L2 U2 4350K which is 172lm/W @350mA Tj50C and cost $4.63/W. The U3 bin is available but it is 6300K.
In the lab Cree claims to have achieved 276lm/W at 350mA in a 4400K neutral white. I am surprised that is physically possible. 100% efficiency for "white" light is probably about 350lm/W.
I got a few XM-L2 U2 to test so I put one over my stove. Replaced a 30W bulb with 1.7W (tiny driver is only 50% efficient

So for once and all please explain the GPW ratio from the 155w a51 panel because i'll tell you right now I can hit 1 GPW on cheap Chinese panels nearly every time using DWC/bubbleponics with at most a 2.5 week veg time. 2 journals at bubbleponics with the same username.
I sincerely apologize as I totally agree with u that I lost my temper because I simply started in this thread in spirit of contributing to the it's title. The following is not an excuse for my actions but an explanation. If u go back to my orignal posts, I did no more than to question the efficacy of a particular panel. No more than anyone here might post when I was greeted with the most severe, racist, and level of animosity that was shocking. I apologize for allowing it to hit home because I've sacrifice a lot to remove myself from this slavery system. I admit my response was over the top to say the least, but I was challenged and insulted for no reason. I then was asked for a suggestion and knew some people might misconstrued it was a sales pitch since I was a little over enthusiastic bout asering the request. Let me ask u if u came across an exceptional deal and you're excited and u genuine wanted to do good u would be excited also when u pass on the deal because it's an actual high in the spirit sense. No more, no less as I sincerely have no fiscal reason nor need to be pitching these petty panels for what, feed me and pay my bills.. I do it because it's a healthy and spiritual high and believing or not is up to one's self after closer examination of the facts realizing hopefully this person has no financial interests motive for this action. If anyone still doubt my ability to do so and wish for further verification, I will be happy to oblige.
