Daz Studio Iray Emission Luminance guide require. Which unit should I prefer?

My requirements are, inside the room, different times of the day and night inside different kinds of rooms. Inside a tunnel etc. Now could you please provide Luminance unit along with Luminance value for different environments for Daz Studio? I also want to know what the Emission Profile is. Where can I find those profiles?

    I do not need exact value but some general settings that can speed up lighting set up. Suppose I want to set up for 40W to 60W non-LED bulbs inside a basement room, what settings should I use? Or a table lamp at night. By the way, it is not one of those popular bulbs changing jokes, but the W unit is confusing me currently to replace a bulb.

    Now I know it is not easy as 1, 2, 3 after reading some other threads.

    Once the Emissive shader has been applied, then emission color, intensity, camera, tone mapping and other aspects related to the emissive properties come into play.

    You can find emission profiles at lightmaker's websites. https://www.lighting.philips.ca/prof/led-lamps-and-tubes/led-hid-replacement/trueforce-led-public-urban-road-hps-mh for example, you can see a column there for IES, those are emission profiles.

    Use one of the absolute values, rather than the per square meter, and set it to the source you wish to mimic.

    Could you provide me which unit are you using. As one of the experts Daz Studio users like you, your preferred unit is something that matters to me.

    Edit: Prefer a particular unit may create division of opinion among users esp. when you are a moderator too, hence not required that information. I will try to find out which unit should I learn. Thanks.

    Thanks, I found some ready-to-use profiles.
