Got this tube today from a friend. It's actually a decently made tube. It has good lumen flow, but is dim after start, needs about 10 minutes to warm up. It has nice CRI, to be honest, in real life it looks more like 55 color rather than 65, aka it looks more like full spectrum daylight rather than just daylight. It had this clear gap so I tried my best to take some shots of the filament, tho they don't looks so good. But the filament is quiet nice and large, compared to some other Chinese f36t8 tubes. Now I have an American made Sylvania, German made Sylvania, Chinese made Sylvania and Taiwanese made sylvania tube. Sweet. What an international brand! Where the heck sylvania even originated from? USA? Germany?

My idol is Mylene Farmer, deal with it.
New lighting technologies is a pity fest everywhere you look. From LEDs that last only for two months, to a never-ending global starvation of t8 fluorescent tubes.
