I got hold of a bunch of led panels rated 36W 3850 lumens 4000k
now for the strange part when i took it apart the LEDs are not aimed down but sideways shining into the frame where there is some kid of white diffusion plate

So the question is are they any good for growing ?
how much lumen do you get out of them without the plates (there is 2 one white and one diamond pattern)

It's a backlight for an LCD screen. Do you really think you can grow fat buds if you pointed your monitor at the plants? You need a normal light. I recommend HPS or MH.

You can probably keep using the strips and the part of the frame they are attached to.
If you build your own frame about like this picture it might work.

It won't be as good as using Samsung strips with high efficiency (I've got Samsung H inFlux) but should still work fine.

Just keep in mind you need about 400W per sqm (Or about 40W per sqft for the non-metrically inclined) of light.
You can vary that by alot , just be aware of the general rule of thumb figure for optional results.

I actually have been experimenting with Samsung LEDs and cheaper alternatives. From what I can tell, there isn't much of an efficiency difference between what's currently used in LED replacement bulbs (once their power supply circuit is replaced with a better power supply) and more expensive solutions.
It might actually just be cheaper to cannibalize a bunch of LED bulbs, mount them to a sheet of aluminum and use a decent power supply.

Totally not true.
Normal run-of the mill LED replacement bulbs rarely have above 100lm/watt.

The LEDs themselves are also only about half the cost.
The heatsink and driver costs amount to about the same when ordering decent quality.

But if you are really that cheap:
230V mains

You can probably find a 110V version of them if you really need them.
If you go ahead and get a bunch of old cpu coolers from somewhere you could pretty much rig up a ghetto light system for dirt cheap.
You'd be handling mains electricity though, so good fucking luck!
