Bought LED board

Fingers crossed.

For heatsink I was wondering if a couple small strips would suffice?

One of the pictures you posted showed a substantial heatsink. With no heatsink would suggest to drive at low power and monitor. You have a multimeter and means to monitor temps? Without the original specifications, we are really going out on a limb,

Have a multimeter, temperature? Not sure how that would go......like one of those laser pointer type?

135 seems like an odd number to me, I will go out on a limb myself and say 100 for whites and 35 for reds....?

Some multimeters come with thermocouple probe that you could tape down to screened/insulated part of the board. Guess a laser thermometer could work too. Seen some recommend pointing at matt taped surface. Something about shiny reflective surfaces.

Ahh yes that makes sense...so I dunno what I'll do bout that...will see. What. Do you think about my wattage theory

Possibly, I have no idea. Without specs of used diodes you are flying blind. Have you viewed the links I posted for you a page or two back?
You have to determine minimum drive requirements and tentatively increase whilst carefully monitoring board temperature.

Have you done any work to plot out circuits? (Judging from vendor pic of red illuminated, there are at least two. Am assuming you purchased only the red/white one.)
What configuration of series or parallel, or series and parallel the circuits on the boards have?
You do not have original configuration with heatsink attached, to begin even thinking of driving at original wattage.

You have to do your homework and work from there.

Yes I did look at them but I don't comprehend these things fully first time through. From what I remember I need a 9 volt battery and a multimeter and some math skills. Not sure if there are places to put probes on sides of diodes from where they are. Individually. Your right, homework was never a strength of mine. I will go over it again though.

Now could the numbered diodes be related to the circuit sequence? Would seem kind of likely, but I know nothing

They are numbered, each and every diode. Red and white seperately

Ok. For those that have been so wonderfully gracious with their time, I asked the seller some questions and this is what he patiently gave me:

 

[Aapoo]

Don't know if this is the complete answer to the power issue

 

[Aapoo]

Oh. And also this

 

[Aapoo]

And

 

[Aapoo]

I don't see a finned heat sink on it but I do see what looks like two drivers suspended over it

 

[Aapoo]

I have a driver. Don't have a resistor yet, to measure fv.

Your screenshot (with ebay logo) shows the vendor supplied datasheets. Why not post them up?

As far as i can understand this is good for the white channel. Still no idea of the red channel. The seller doesnt mention anything but 24V but i assume this is only for white. Get any datasheets you can and post them. Photos of both of the drivers while in operation might also help.

 

[Aapoo]

Those were driver sheets so far as I can tell but will do.

 

[Aapoo]

Here they are.

 

[Aapoo]

That's all he sent and all I have.
