Monday Mutant 28: Process of Illumination (EX)

In this Process of Illumination puzzle, a number in a circle represents how many light bulbs are on cells which share an edge with that cell, while a number in a square represents how many of the edges of that black cell are illuminated by light bulbs (the top and bottom edges can only be illuminated vertically, and the left and right edges and only be illuminated horizontally). Some of the black cells are triangular; like other black cells, they cannot have a bulb on them, and they don't need to be illuminated. However, these cells function as mirrors, and reflect the light of any light bulbs which illuminate them. The rules are otherwise unchanged.
