March Mutant 3: Process of Illumination (all 3's)

In this Process of Illumination puzzle, a 3 has been placed in every black cell which could legally contain one. The number of light bulbs adjacent to a black cell without a number must not be 3. The rules are otherwise unchanged.

Coincidentally I made an all 2s and 1s variant just recently, but by my understanding this must have been quite a bit harder to create. I liked the behavior around the 2 diagonally adjacent 3s.

Are we to expect daily updates now, going by your 3/3 in March so far? :)
