Puzzle #2

This is an Akari puzzle.



Difficulty: trivial

Theme: Light Up (in celebration of 4/20)

Puz-PRE link.

For those of us who don't know, Akari was originally called "Light Up".

For those of us who don't know, today is 4/20 in the nonsensical American calendar system, a day that people who smoke marijuana tend to celebrate, by lighting up their joints of marijuana and smoking them, as well as doing other things.

For those of us who don't know, mathgrant came up with this pun, and I just couldn't resist seeing it come to fruition.

For those of us who don't know, I've stopped making my puzzles in Paint.NET and started making them instead in Puz-PRE.

Rules of Akari

Place lightbulbs in the white cells according to the following rules:
  1. Lightbulbs light up all cells in the same row and column, including the cell they're in, up to a black cell.
  2. All cells must be lit up.
  3. No lightbulb may light up another lightbulb.
  4. Numbers on black cells represent the number of lightbulbs orthogonally adjacent to that cell.
Below is an example and its answer.
