Id say if you can afford it, use more COBs at lower amperage.

I don't see anything new.

Watts are watts. If the CFL draws 125w I wouldnt recommend putting it in a 40w max fixture. Unless its a "125w replacement bulb" as it in replaces a 125w incandescent. What does it say on the bulb?

10-20 years until fed legalization Im saying.

Youre referring to the different voltage versions, not wattage. Correct? Also, maybe the pattern is designed to run at a higher voltage wont necessarily work as well in a lower voltage situation. The fact is ~70v+ COBs really limit the available driver opportunities compared to even the ~50v...

Doesnt it have to do with the differences in die patterns? Or is there something inherently more efficient about running more voltage through a COB rather than pumping more current through it? Just spitballin here.

Id say its always a good idea to look over the specs sheet of products like this when building any project. Never hurts to ask but you have to know who youre asking is giving you the correct information or leading you to the right spot. And yeah, its definitely comforting to know the...

Why would you use it to judge something if it isnt accurate? This is why I love this planet. Who gives a shit about accuracy. Im all about that G. P. W. Baaaaaby!!!!! Honestly, g/w is the equivalent of an e-peen. I say wave it around to your hearts content, everyone else is...

Honestly, I had no idea how fast this shit was progressing until I stumbled upon this thread. Its like a godsend for the DIY community. Thank you so much for bringing this to our attention! Which 3d software do you use?

I think the problem your having is the fact that his setup covers all his cooling needs and does it rather efficiently. Asking him how much power his uses is kinda pointless because his cooling needs dont align with yours. Given the same amount of BTUs, one should be able to build a more...

Remember tty that all of this was started in your response to me saying I could DIY a smaller version of your setup for far cheaper and make it just as reliable. Then you started going off about how "ACs and Chillers werent the same". Its important to remember we were discussing their...

Thank you very much for that info!

Hey, could you tell me the heat transfer plate measurements on the back of the COB? I was thinking around 38x38mm but wasnt sure and couldnt find anything.

Are you implying you like to carry out the experiments yourself? Or that you would rather just take peoples word for it? If its the latter, peoples opinions always differ on subjects like this, so without any hard data, how do you choose who to believe?

I have this model(A) and my multimeter says its putting out 1.55a with pot fully maxed.

I agree, but the fact is, the vast majority of people probably dont know how many KwH's they used for their grow or care to calculate it for that matter, but they could answer in their sleep how many watts of lights they are running. And I believe thats about how far most care to think into it.

You can ignore my previous response to this, its just too much fun calling you out on shit lol. In regards to my "strange ideas" are you referring to my idea of the DIY chiller using 2 ACs for redundancy that would in theory by more reliable and far far cheaper than your setup? If so Im left...

So how long have you been studying the topic of Chillers and Air Conditioners and their subtle differences? Thank you so much for educating me ;) I now see why tty didnt want to go so far into depth with his explanation in order to educate me. It clearly would have taken far too long. I...

I agree G/KwH is a better metric, but it can pretty easily be deduced from G/W assuming you have times logged. Case in point: Depends on how you describe "better deal". Person "A" used one unit of electricity for 1 unit of product. Person "B" used twice the electricity for 1.5units of...

Yep looks like I was wrong. I guess the two just need to be looked at separately. Thanks for checking, maybe Ill look more into it or something similar in the future.
