    We are seeking to buy a desktop lamp for print/monitor comparison. We don't want to spend the amount of money required for a proper viewing cabinet. We are seeking a straightforward D50 desk lamp with good CRI ,etc. It would be useful if the light can be dimmed to match monitor brightness.

    Any recommendations would be appreciated.

    Sounds like you need a GrafiLite. Wex have them but are currently out of stock.

    No dimmer but other than that I find mine very good.

    The best colour-proofing bulb available is probably the Solux, although I have no idea about its UK availability (if that's required).

    The CRI is a misleading spec for photographic purposes, and the specific D50 standard illuminant is unlikely to be achieved by any household fluorescent tube or Biax lamp. The best they usually offer is a correlated colour temperature, which is an entirely different thing.

    Not sure if you can dim the Solux - ordinarily halogen is dimmable but the colour of light is liable to be affected. So you'd likely have to alter the distance.

    Philips used to make Solux MR16 bulbs under their Diamondline Pro branding but not sure if this is still the case.

    Some of the latest LED bulbs are dimmable, the better quality ones will probably be a fairly consistent colour temp I would think.
    Might be worth considering.

    Another vote for a GrafiLite but nope,sadly no dimmer button Sad

    Does one not really need a suitably colour corrected ceiling bulb in order that it illuminates the monitor as well as the print ?

    The GrafiLite appears to be just for viewing prints.

    The monitor has its own illumination.

    But is not the monitor illuminated by the room light, right now mine is on and I am certain it is throwing a colour cast onto the monitor.

    Hence the reason you don't want the light hitting your monitor. At least not when editing images or any colour critical work.

    Was that room light on when you calibrated your monitor?


    But yes, ideally you should shield the monitor from direct light or work in the dark.

    Colour temperature in fluorescent or LED lighting is ambiguous, particularly when the aim is to match entirely different products. So in that respect a 'colour corrected' ceiling bulb does not exist - correlated colour temperature always refers to a range of colours. The same is true of monitor backlighting, so if you're trying to calibrate two entirely different screens you're better off attempting to pin down a specific colour (i.e. D50 or D65) rather than nominally identical colour temperatures.

    The Solux is unusual in that it combines the smooth spectral distribution of a filament bulb (something vaguely akin to daylight) with a cooler colour temperature - which would melt the filament before it could be achieved through conventional means. No other light source is going to be that natural-looking, or render colours with the same consistent accuracy.
