Hello, I've had a look in the manuals and can't find any reference to Light intensity requirements, only if the lights are working or not.
The minima will be based on what TYPE of lights are available and if they are working or not. However, I stand to be corrected.
My answer in the interview would be that, but also, ask when am I being asked this question. For example, if it's in the crew room, I would refer to the companies manuals to look at the downgraded/ failed facilities table and also the RVR Vs Approach light table to see if there is any information and possibly also ask a management pilot or Captain for their insight.
On approach - I would continue and comply with the usual rules.
