Bringing this back up, I have just calibrated my monitor with a spider 4 pro, And the brightness as suggested was 120cdm2, but after reading Damien's guide whilst setting it up and using his recommended option choices

, I went lower than that to 90cdm2 but it still seems really bright, I have sent off some test pictures to see how they come back,
Is it worth re-calibrating again with lower brightness.
Wait until the test prints come back, and tweak the settings as needed. As to re-calibrating, it's not as much about the brightness but especially about the color-matching.
One thing about the brightness, though: when you check those test prints be sure that you view them in "good" light. This will typically not be the light that you use to edit. Viewing prints should be done in light in which, well, they will be actually viewed, enough light to bring out the details. Now, you can buy lights that will be "neutral" and bright enough...although taking the print outside in daytime but not in direct sunlight can for "normal" uses be good!
