Use Maintained emergency light as normal light in garage

[Niscars]

I rescued a couple of these fluorescent emergency lights from work and was hoping to use one of them in my garage as a normal on/off light. I don't want any battery backup, just a normal light. Based on information in posts online, I have removed the wires from the emergency module and battery and have rewired the unit following the diagram on the ballast as shown below.
When I turn it on, the tubes are only lit for about a second, then go off again (same for both units).

Have I done something wrong or are they both u/s?

Model details: (NVC NAK258/HF/M3 is a 2x58w, high frequency, 3 hours maintained emergency magnetic gear luminaire).

You may just be playing with it, but the fitting really should be connected to an earth.

It's too unclear to see what you have actually done with the white wires

Thanks, that is slightly different to my diagram but I will try that after Xmas.
