This is filmed on 11 May. This fluorescent tube has reached EOL since 7 May, but the program start ballast was never gonna give it up. If the lamp has already shutdown, switch off for at least 15 minutes, and switch on again, the bulb will turn on like normal for few minutes.
On this day I turned it on for twice, at first time the ballast shutdown the bulb after 2 minutes (not recorded). For second time the bulb stayed on for about 5 minutes and then it died.
After this day until the bulb get replaced on 16 May, it would just make few flashes and remain dead when switched on.
Both the EOL and replacement bulbs are 4000K.
