Ok, so I you go to my gallery and look at the number of posts in each album, you will easily see that my favorite light source is the Fluorescent lights and here is why:

So when I was a kid (about 6 y/o) I looked up in the cold section in a grocery store to see these long illuminating oversized straws (that is what I called them before I knew what they were called) and wondered how it actually worked. As a 6 y/o I didn't know much about lighting and didn't know about LG either, so I thought the oversized straws worked by a long filament stretching side to side, sort of like a lumiline. After holding that belief for 7 years, I came across this site on google images, I then realized there was no stretched filament and just two filaments on the sides, I found it so cool at the time how a lamp could be made with an arc. Some time after my birthday in 2016 I came across LG and now I know a lot more about fluorescent light

The same concept goes for any other light source too

Lets hear your stories on how you noticed, became interested, or whatever on lighting (NOTE: It doesn't have to be just fluorescent, it can be any light source(s) that you started liking first)

Mine is almost word for word the same as you  , although I was a bit older at 8, when I started to be fascinated with our 5 foot fluorescent batten in our kitchen at home, I too thought exactly the same as you, that there was a very long filament in the tube!  , we called them 'strip lights' though as kids!, my lighting interest really took off at the start of the 80s though, when we lost our MVs for low pressure sodium lamps in the streets!, I wondered for years how a light could come on red, then just automatically turn orange on its own!!, I didn't see one running close up, until I was about 15 though, when me and my mate became friends with a street light engineer, who made us a display board up, and supplied us with the lamps to run it on.  

Mine started at around the age of 2, maybe 3 years old. First fluorescent light I've ever seen was a 4 footer WW halophosphate
F34T12... on a Preheat fixture. This was in the basement at my Grandma's *former* house. (she died) I also got to see a circline for the very first
time as well, which was also preheat. Second kind of lighting I saw as a kid, was in pre-school. Rows of Louvered Rapid Start fixtures...
also, very tall ceilings as well. The lights seemed like full wattage F40T12's, all cool white, with yellowish plastic covering on
the sides of each fixture. I absolutely loved the way they fired up, and THAT is where my lighting enthusiast journey began,
even more so than the preheat fixture in my Grandma's basement.
First EOL show I've ever seen, was also with Louvered Rapid Start fixtures, although this was in 2nd grade... totally different state
as well. Metallic sides with these fixtures, no yellowish plastic covers.
The EOL show was impressive despite it being Rapid Start, and I instantly caught the orange flashing and orange snaking swirl from
the bad end. My heart jumped out of my chest and I remembered mumbling "Oh no." I thought that lamp was going to explode. Then
both lights in that fixture dimmed down to the dim flickering, and after a while I remembered thinking about how cool that
was. From that point on, I would always look around for more lamps going EOL.
This is when my lighting enthusiast side of me REALLY began to show. I also began to take an interest in MV and MH
as well as Sodium lamps.

我是觉得荧光灯在通电时会闪烁一会才会启动比较好玩，所以..
