Some of you long-time followers of me may remember that in 2014 I posted this tube. I presented it wia one picture only showing the etch, while in the background was showing my proud rebel-child pile of mess of a room. I am ashamed. I sometimes go back in my gallery to see my old pictures and I see how messy my room was and how careless I was with my tubes when I was a kid back in 2014 - 2015. Today I present to you the new and improved presentation picture of this tube. You can see the etch more clearly, and you can see the tube lit. It has a very nice yellowish warm white color, and is moderately bright. It has a pretty long life too. I got this and 6 other same tubes from my third school. I asked the school keeper if he had some old tubes and he gave me a full case of these and other various tubes like Philips and GE polylux, and on the case it said "burned out tubes" but after testing, 17 out of 25 tubes, labeled as "burned out" were perfectly good. Odd. I have never seen a Sylvania so-called "New-generation" till then.
Also, fun fact: Right about till 2016 I thought that Sylvania was a country that made tubes :P . . . I was a dum kid XD
