led cob light pull apart

[N3ro]

OK so I have two units of the alleged 200w lushpro LEDs which are really 92w lights, now the first unit a gave to a mate a year ago to hang on to and the cunt gives it back with two burnt out cobs, literally fucking fried.

 

 

 

I'm looking at the LED drivers looks fine to me input 00-240V AC50/60V output 70-85V DC constant current 520mA.. .

 

Look at the fucking LED power supply 12w-121A, max output 12W, now I am assuming this is not for the light but the fans, I'm wanting to replace the chips as it would be a waste of a unit and wanting to know if its possible to even put 200W chips on it?

These are the chips I'm really looking at.... I know my computer shit but I'm not an electrician the assumption I'm making is that the drivers are lower than the current chip set under clocking them, would it be worth putting a 200w chip in? I might even look at the fans and get more powerful ones and replace the drivers to fully get everything out of the chip and not under clock it.

Why not put two CREE CXB 3590 chips in it 36v each run them at 500mah or whatever your driver is, i think you'll find your power supply is 12watts 1amp 12volt ohms law

The formula to convert volts into watts is

Watts = v(volts) x i(amps)

Ohms law v=i(amps)x r( resistance)

I thought it was volts x amps = watts because your watts are not known before the calculation

I'll have a look at these cree chips

Watts = v(volts) x i(amps)

Ohms law v=i(amps)x r( resistance)

Can you show how the equation works with mA ? If I get this right I might be able to replace the chips with the CREE ones.

It would be interesting to start a thread about hacking cob units from China and refitting them.
