Puzzle No 162: Double Thermo Sudoku

This Sudoku was created in an attempt to invent a new variant. Although later I was notified that a similar (but not exact) variant already appeared on the Cracking The Cryptic youtube channel. Anyways this should be still fun to solve and explore.

Rules:

-Normal sudoku rules apply: In a row, column, or box, the digits 1-9 have to appear exactly once.

-Thermos: Along the thermos, divide the numbers as a group of 2 digit numbers and these two-digit numbers must increase from the bulb to the end. 2 digit numbers are read in the direction from the bulb to the end.
