With more recent versions of the Spyder software we've instituted features to help assure that people are using luminances (display brightness levels) that are appropriate for their type of display, and for their ambient lighting, or proofing lighting. If your product does not offer ambient light measurement and suggested luminance levels, then you have to deal with this yourself. In moderate lighting, with a newer LCD, 150 would not be unreasonable. If your lighting is dimmer, then 120 might be better. If you work in the dark, as in the old days of CRTs, then even 120 would cause a lot of glare and eyestrain, as well as being too punchy to match prints in a dim viewing condition. 90 would be a reasonable choice for such conditions.
