2 Hg Starved Ecolux F40/D tubes

2 Hg Starved Ecolux F40/D tubes

These came from a neighbors shop. Both were in the same fixture, oddly they were still starting on RS.

Here they are shown running in one of my 3 T8 wrap fixtures. These are both Daylight Ecolux F40s. Notice how the dimmer one is more redder than the other even though they are both 6500k phosphor?

To judje if it is mercury starved or air poisoned, look at the spectrum of the lamp. If you see the atomic lines of the argon/krypton, it is mercury starved. If you see molecular bands (Mainly in the blue and red), and if you touch the lamp and it is hotter than normal, it is air poisoned.

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

Its likely that in this case, they were both just starved of mercury, one being worse than the other, GE has been pretty stingy with their mercury dosages at times. These lamps were in a shop fixture that was lit 24/7

Since they are interesting and not actually EOL and still work on RS ballasts, they are a welcome addition to my collection.
