Lightning and node setup

Hi, not sure what to do, I have spent days on this. I am trying to get the image to appear as lightning, not just a blob.

The left image is what I what to show up, and the right image is what renders.

Your Less Than node is looking for values below .9, and so is picking up the subtle glare around the lighting in your image.

Perhaps you meant to set it to Greater Than?
