Most of us have a camera with built in light meter, but we do not have a lux meter. I am sure there is a way to use a camera to measure the light from a bulb, but I would guess the bulb would need putting in a white box or camera aimed at a grey card or something similar.
Colour of walls in a room, size of room, where the light points to will all have an effect. But not really wanting an accurate measurement just an approximate way to measure light so we have some reference point when talking about lighting. Easy enough to convert aperture, speed and ISO into an exposure value (EV), but it's the where to point the camera.
Ideas please.
