Monitor calibration and lighting

[imported_ganna]

I recently purhase a Spider 4 from Datacolor and is quite happy with it. I need some advice please.
1 How often do you calibrate/recalibrate.
2. Is there any special precaution as far as lighting of the room is concerned or will the calibration process take care of that?  My study has a double 4' fluorescent light and I mostly work on my computer at night time. Is it adviseable to put daylight coloured tubes in? The light is quite bright.
I have a Philips Q4H 24" IPS monitor. Interestingly I find that the  hue numbers on 2 different computers is not exactly the same, though close. The other computer runs a Samsung LED monitor, 23", both computers in the same room and both calibrated. They do not face the same direction, about 2 steps apart. When I switch the light off, it's too dark to see the keybord

Cool choices...

1) I check mine every 2 weeks,  that does not equate to making changes most of the time there is little or no change needed.

2) I do my calibration in a dim room with as little outside or extra light as possible.  getting 2 PC's to agree can be a real trick; or impossible get them as close as you can; and choose one as a primary...

Greg, do you just calibrate in dim light or do you do your editing in bright light?

Both Dim...

I have overhead lights that are 3200K LED but I keep them off or very low....I also have a small desk lamp that I use to light the work surface but I try to keep the light from hitting the monitor too much. I have a small piece of cardboard taped to it to shade the side that would hit the monitor.  Not perfect but better than nothing.

Thank you, a desk lamp make sense; perhaps with a daylight led or tube to give 5500 to 6500K

I like that Idea...

Gotta go shopping now
