Why no red COB's?

[rob333]

Thanks. 1 umol/J is what I'm seeing in the datasheet for the red channels at nominal current. Assuming the all red cobs will operate at similar efficiency they will also be around 1 umol/J.

soon as i get a trial light ill set it up and post week by week till we are done

Same here, kind of. Good friend of mine has 2 stores and when my work is slow I work for him.

It's just that, sourcing a PPFD meter is not like shopping on amazon.
Each PPDF has their own measuring specification, some do not measure as low as 450nm, and some do not go as high as 660nm.
Some don't come with spectrum filters, some don't come with attachable ppfd readers and must be hand held .. etc.

So, we custom ordered a lab grade ppfd meter which takes time to manufacture and build. So I do apologize for not shopping on Amazon Prime.

So you can build a red chip better than cree,but you dont have the wherewithal to even have a ppfd meter? Really? Peace bro im out.lol

Plus, UV is only useful for less than 20 minutes right as lights are/going out.

What? How did you figure that out?

 

[nevergoodenuf]

Air- you're confusing far red 730 with UV. Flip Chip is working on adding UV to the COB.

Sounds good. You will be using the Duet? The blue channels are 3.34 umol/J making the unit overall 1.84 umol/J according to the datasheet. Will you be running them at nominal current? I do appreciate the availability of datasheets and the opportunity to test blurple with known parameters. If blurple is worthy then 1.84 umol/J should pull decent numbers, though the efficiency on those reds isn't exactly something I would brag about.

Give Rollitup some moneys and you can have a blue ribbon too.

 

[captainmorgan]

Maybe we should go back to blurple lights.

 

[BOBBY_G]

i havent written off blurples yet. gimme 4 weeks

I'm willing to bet that you'll show that the COBs outperform the cheap blurple lights, just like was shown a couple years ago with the top bin CXAs Good luck!!

 

[captainmorgan]

I'm thinking of dumping my lights and going for some of those cute painted CFL party bulbs.

I mean, unless its a stock market scam and dude is trying to hype a fake company, i'm kinda excited to see these products. Of course, i'll be buying only through amazon prime.

soon as i get it ill inbox ya and give u the low down

So he's sending you a test flip chip duet2400 to test?

My bad. Uvb is 290-320nm.

 

[Airwalker16]

Any links to a decent UVB diode? Or am I better off just using reptile bulbs?

we will find out if he does or not

Shit I want one to test. What kind of driver would you use.

not to sure yet not gunna get anything till i get it in the mail
