A more modern fluorescent light is the fluorescent induction light. The bulb has a gas inside, and phosphors on the inside surface of the glass tube. BUT, they use an induction coil and pump it with power at around 200kHz to 300kHz. They have no filaments inside the bulb either. Hence, there is no metal to glass seals to be made, both of which greatly extends the lifetime of the bulb. These have been put to use the past few years as street lighting in our area.
Yeah 200lm/w sounds like BS.
Usually LEDs get around 80 to 120 lumens per watt.
