Spot Light Limit ?

Hey guys,

Straight to the topic, I recently discovered that, if I create more than 30 spot lights everything turn out black and I get this errors :

I got blender set to use my NVIDIA graphic card (GeForce GT 750M) with 2GB (and Computer Ram is 6GB) and Blender use like 30MB for whole scene top.

Is there any way to increase the maximum Spot Lights that can be used in scene at once without the whole scene going black?

Or is there any other way to use more like put 30spots on layer 1 and other 30spots on layer 2 ? (Which does not work btw, hiding(Visibility,Rendering) them does not work either).

Thank you
