So im thinking of grabbing a few of these to throw in my cluster.

I currently have these and im absolutely sick of the hot spots. I hate that sooo much.

Besides sanding the LEDs down (which ive already done) can the hotspots be eliminated somehow? I hate to fork over $30 for the SMD ones just to have even worse hot spots...
