However it doesn't always go to plan....the tube from March 2015, which was virtually the same brightness as the 6 month old tube has suffered a premature failure. 🙁 Blown heater, which is strange as I thought modern electronic ballasts dont use heaters.
Whilst sorting this I noticed one of the other tubes, only a year old is not very bright now. 😡 Has flickering section in middle, indicating a pressure loss. Upper tube is brand new out of box.
Compare the new tube (upper) with other year old tube, exactly the same brightness (once all the scale and dirt cleaned off the tube).
