Flip Chip Opto High Power Build Thread

I thought you said the LER doesn't change....oh. a...a...he he...a you make a jest? No?

Nah
I was just making obvious your invalid logic.

OK, I found the right sized in BTU/hr of new exchangers for $200.

$200- radiator
$100 - fan & shroud
$320 - 2 x COB P/N : P110-15S19P-3080
$380 - 2 x Driver P/N: HLG-600H-48
$150 - 2 x cold plate
$170 - 1x 2 gallon/hr pump and plumbing
------
$1320 + delivery

50v@12a = 600w x .52 = 312wPar

$4.23 PAR Watt.

Really? So you know how to make them so efficient they actually make power to sell back?

I don't, Mr. degree in physics.
I was joking about your - and excuse I have to be harsh there - fucking stupid idea of dividing input power by LER. It's a nonsense. Why would you do that? Your result - .54 - would be in W^2/lm units BTW.

 

[Doer]

But, it got you here.

 

[alesh]

But, it got you here.

Yes, it did. And perhaps I helped you realize your mistakes. Do you find my presence positive or negative?

I gotta admit that more you write the more I'm enjoying that. By all means, please continue, Mr. degree.

Damn. I blew it. IAC, It is 2 COBs so 624wPar.

$2.11 PAR Watt

I find you to be an invaluable member of the team and I am putting you in for a big bonus.

I was going to try raising to the 2^sq root, next.

If that only were the only thing you blew...

 

[Doer]

Pretty good price though, you gotta admit.

 

[alesh]

Pretty good price though, you gotta admit.

It would be, yes. Sadly your calculation is far from being correct.

 

[Doer]

Woops. Oh, how sad. Would you help me? Please?

Really I should have listened better in the first place.

No problem, Mr. degree. Just drop the nonsense efficiency value you produced and replace it with an appropriate one. And no, efficiency is not input power divided by LER as I have, hopefully, pointed out earlier.
