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.
This variation comes via MellowMelon.

Very fun stuff. Your mutants have been very enjoyable. With the pseudo retirement of Mellow Melon, I have appreciated your picking up some of his variations and revisiting them

I got the meaning of the squares and circles mixed up the first time I tried to solve it. Once I had them straight in my head, then it was a fun solve.

To keep the meaning straight, I imagined circling the number to touch the adjacent lights. And for the square, I imagined the sides of the square getting illuminated by the lights.

Some nice reveals in here. Gets me thinking about a "colorblind" version.

Guess what? If you include the two birthday cake puzzles and count the Attack Of The Four Puzzles! puzzles individually (ie. as eight puzzles instead of two), this is your 500th puzzle on this site. Congratulations!

The Grim Recapper: the puzzles on my birthday cakes are actually puzzles 180 and 392, so you're counting them twice. As of right now, I have 426 puzzles, plus 16 Evil Zingers, 28 Monday Mutants, 8 puzzles in the two Attack of the Four Puzzles! contests, and while I really refuse to count them, 25 example puzzles from the rules pages and 19 user-submitted puzzles from the Logicsmith Exhibitions. I'll let you add those numbers up and do the math.

478, plus the Logicsmith Competition entries, which IIRC still takes you up into the right area, but it may be a few puzzles behind.
