Crime scene: 162 mystery solving puzzles to find out who the murderer is

Chapter 99 The Night of Spring Thunder
This is a rare night of thunder in spring.When a writer of mystery novels living alone was writing a work in an apartment room, he was suddenly stabbed in the back and died.

When the body was found the next day, the fluorescent lamp on the desk was still on.This is a simple fluorescent lamp without a starter.But strangely, a flashlight on the desk was also on.

"From 10 o'clock last night, the apartment's electricity was cut off for about 30 minutes. The substation was probably struck by lightning. Therefore, the victim must have been killed while writing a novel with a flashlight during the power outage." The administrator said so.

"No, the murder occurred after the call. The murderer deliberately turned on the flashlight to pretend to be a power outage, and then fled."

The criminal police just glanced at the scene and made a judgment.So where is the evidence?

[Answer] A fluorescent lamp without a starter will not turn on automatically even if it is powered on again after a power outage, so it is obvious that the deceased turned on the lamp himself after the power call.
