Light area effects ++

[Lomaz]

So I did what was listed in this post: http://www.html5gamedevs.com/topic/6771-masking-to-simulate-light-area/  And I was wanting to build on it but not sure how, basically, I have the shadow effect around my sprite when he's underground.. and it follows him as he traverses the map, now what I want to add is static light points on the map, like torches, or cave enterences, is that possible?

 

Here's what it currently looks like.. http://imgur.com/EXqjGlV
