I offer all my customers the choice of Vero 29 and CXB3590 cobs and not just one series. Who said anything about a CXB3590 running at 5.2A? Again, if MeanWell approves of my applications of running cobs in parallel, then I don't really see the need to fear monger or worry about worse case...

Typically with driver selection, I choose version B drivers from MeanWell, as then lights can be dimmed by an external knob. In the case of one of the lights that was sold to Hanzo, it was equipped with a version A driver, as it was during the Chinese New Year and no vendors had the version B...

Well not everyone in the world gets along, so I understand your stance. Call it passive fear mongering if you may. I use 36V CXB3590 cobs, I've ran them and CXB3070 cobs at 2.86A before, no problems when properly cooled. The max current for 36V CXB3590 cobs takes place after 3.6A, with the Vero...

Haven't seen SupraSPL in awhile. :confused:

@PurpleBuz You love using that word Poppycock, don't you? Lol. Is efficiency derived without taking into account current? So we're both right about that part, which is why I said there are multiple variables that dictate the value of PPF/W, including efficiency. I care about a lot of things...

O, an I/O switch? That's cool, so it's like a built-in dimmer I take it or does like a light go out or something? I've seen a lot of 'straight outta China' panels have a similar wiring configuration where hitting one of the I/O switches turns off some of the lights.

I think those power cords are like a 1$ on ebay when ordered in bulk (~x100). @Federson Did your light come with a dimmer knob or something?

Looks familiar? http://www.alibaba.com/product-detail/COB-LED-Grow-Light-Panel-Full_60420271508.html?spm=a2700.7724838.0.0.V04GRY

@PurpleBuz PPF/W is determined by a few different variables, mainly by current. The error in @EfficientWatt 's argument/point is that he left out the fact that my fixtures possess a dimmer knob, so my PPF/W for my fixtures can be attuned to various levels and aren't just limited to 1.82 PPF/W...

Lol. I see a bunch of effort being wasted in here, that's all. Don't know why either side is putting so much energy into whatever this is suppose to be; it's almost become a tradition on this forum and LED section that Sativied comes in, finds a way to start a +10 page debate between himself and...

Acorn nuts work well for that sort of application. It's a nice looking fixture, Airwalker16 - good work!

@Sativied I'm just curious on why you're in the LED section once again stirring the pot with all the fellas and chickas here. I can only guess at this point. You should bring into this thread some like-minded individuals to sort of level out the playing field though.

@Airwalker16 While glancing over photo 2, I thought I saw q-tips in the corners of your fixture... lol

@Sativied What's at stake here for you?

@captainmorgan LMAO! Right?! It's been at least a year and he's still as persistent as he was before. I jumped into this thread and it was like going back in time for a second, whoa.

@Sativied Lol, you don't give up very easily do you? Kudos to you, even if we support different lighting methods.

My tests are a joke? Why don't you prove your claim instead of openly discrediting my efforts without any proof? Why don't you first build your own diy cob fixture and then recommend what people should and shouldn't buy? Like you said before, it's not that difficult, right? How long have you...

@littlejacob Hey Jacob. Regarding your question, the short answer is yes, we put more energy in that comes out when transforming high voltage to lower voltage. Every percentage counts, even at a small scale, which is why it's important to use efficient, quality drivers. It's important to...
