Not sure if that is directed at me... but YES! I will take a look at COBs in the lab, and I like the specs on the CXB's. putting in an order right now for a prototype... I will post my quantum meter results when I get it set up.

it was directed at any one so thank you for clarifying that those woud in fact work together thank you very much time for me to get ordering again thank you very much for the clarification

thanks for the info! all I am solid on right now is the oslon ssl hyper reds. I will put the numbers for efficiency/cost and see how to best integrate white lights. Have any idea of what the thermal resistance would be on these COBs? wanna keep heat sinks uniform and inexpensive.
COBs all the way. Various COBs have various thermal resistance - consult data sheets. CXB3070/3590 will certainly have lesser cooling requirements than Oslons - they're more efficient and the thermal path from junction to HS is w/o PCB.

I see something wrong with your math.........what is the value of the labor to build 80 lights? WHO is going to build them, you?? There is no way this is a one man op, so you'd need to pay people to build them. How much will that cost? sure as hell you don't want someone hired at minimum wage doing it!
then each one has to be tested and corrections/repairs/improvements made until every unit. You don't build anything from scratch without expecting to spend a little R&D time on them! This could end up costing you more than buying top shelf comercial LED lights.
then you have the problem of people with no electronics skills trying to build a device that will be reliable. and there WILL be fuck-ups with this scenario! Sounds to me like you think you'll just buy a bunch of parts and bang them together.
As a former business owner, it sure sounds to me like you haven't done your homework. I haven't even scratched the surface of the complications of this! Here's another one for you:
Electrical inspection. do you think they will pass inspection? are they going to be UL tested? If not, and they somehow manage to pass the code inspection without it ( HIGHLY unlikely ), what happens if one catches fire and burns down your op? I'm willing to bet the insurance company would screw you for having DIY lights.

Again, don't get me wrong, I love DIY lights and I know they can be very effective. But considering what a grow-op this size is worth, it would be foolish IMO, to waste time and risk your business doing this!

Start thinking like a business owner, not a hobbyist looking for a headstash!



3 fruiting rooms, a total of 80 4' by 4' grow pods. that includes our 2 R&D rooms. We build for 1000 vs paying 3000. get a better product. 80 * 3000 = 240,000. 80 * 1000 = 80,000. 240,000 - 80,000 = 160,000. Now I know that we would get a huge discount but the product is big enough and doesn't have the spectrum of light I want.

sorry, I don't smoke. I am a biologist. my partners are electrical engineers, production managers and contractors... don't worry, we are a large enough company. I promise you that we have been crunching numbers since the license was being applied for... but thank you for your concern. we are going to science the shit out of this and wanted to share what we were doing. you are correct about the math but that was already realized. didn't think this place would be so hostile... but there are trolls everywhere. peace out and I will head somewhere else. see ya. last thing before I go. most people in this world don't do great things because of fear... don't be a fear monger, if you every have children or are put in charge of any humans I hope you re-think your stance on peoples ability. YOU can do anything...

thank you everyone else.

Not trolling or hostile, just constructive criticism because 1 in 10 of these projects fail due to poor planning. As to people's abilities.... yep, I'm a huge skeptic! I've worked in mechanical/technical jobs and have had co-workers who scared the shit out of me with their ignorance and stupidity! But even ignoring that, do you feel your exempt from Murphy's Law? Even the most well thought out plans usually have a few bugs in them!

So yes, I have no doubt it can be done. But we're back to who is going to do the actual building of the lights? You and your partners? How much is your time worth? Yes, with partners like that, you could do the prototyping, etc. Considering the time involved and the value of the talent, those lights are costing a lot more than $1000 each!



Yes fear has no place in the minds of those who want to accomplish great things! However, it takes planning with great care to succeed. Opening up your plan to others is a great tool also. no matter how well put together your plan is, expanded comments and criticism will point out flaws that may have been missed.

I look forward to seeing this project! You should start posting pics of your op now, and as you progress. I can't wait to see 80 DIY lights all lit up!
Good luck!

"didn't think this place would be so hostile... but there are trolls everywhere. peace out and I will head somewhere else"

Did you think think we'd all just say" Atta Boy"! If you can't take criticism, how the hell did you make it through the licensing process? I've seen what that entails and they certainly don't go easy on you!

Then again, maybe your just blowing smoke up our asses. talk is cheap.

sounds like you and your partners are some smart cookies! My primary training is a plant breeder from a little place in upstate NY

You save more using Cree CXB 3590 and the run more efficient @pop22 quit being a dick and show us your lights
Thanks, that is what I'm going to put side by side with the oslon whites. I really like the looks of the CXB's!

Since you can place a reasonably large offer I'd look into 3000K/90CRI version of the CXB3590. It has an amazing efficiency for a high CRI LED with lots of output in the deep red range.
so how do the numbers compare for a 90 cri versus a standard 80 or 70 cri cob plus top bin supplemental 660 nm deep red stars ?

It's for the 3590, both efficiency- and cost-wise IMO (IDK of any deep red LED that can be purchased and run over 60% in real world conditions).

60% doesn't say anything, cause your not applying that 60% to the whole package with the right ratio of 660 put into perspective

I'll apologize for the blowing smoke comment. however, what about my questions was wrong? Its ok to ask about a design but not about the thought process in taking this approach for a business? I just wanted the why and how of DIY'ing business equipment. Wouldn't those answers be useful to others thinking along these lines? Does this approach make sense for a business?
Maybe I'm just not good at asking the questions, sorry. I'd like to see him post a thread with in depth information on the mechanics of this operation.
Sharing information. Isn't that what a forum is about?
