E26 (ie household 120v) High CRI D50 Bulbs?
« on: September 12, 2013, 10:22:30 pm »

I'm looking for a high CRI 5000k bulb for print evaluation.  I know about the Solux PAR bulbs but they're 3000k unfortunately.  Suggestions?

Search out the KinoFlo® KF55 26 watt, medium screw-base(E26) CFL bulb.
KinoFlo is a 25-year supplier of lighting instruments to the motion picture and television industry, and pioneered the "truly color-correct", photographically useful flourescent tube and related fixtures. It's 5500ºK and not 5000ºK, however.

Perfect, thanks Pluton!  5500k is fine.  The main things I'm looking for are high CRI and daylight balanced, this fits the bill.

I'd go with the Solux bulbs anyway. The idea that 5000K is important is a myth - what's really important is the CRI and that's where Solux excels. Since human perception has chromatic adaptation, we adapt to these different color temps, except for a subtle psychological effect. Cold light 5000+K lights gives us a feeling like we're in a sterile hospital environment. Warm 2700K lighting gives us a homey "I feel like sleeping" feeling.

IMO, High CRI 3000-4000 is the perfect temp for critical print viewing as it gives us neither of those impressions - when you walk into a room light in this way it just feels right. Just my opinion! [as someone who consults with a lot of people internationally on lighting and CM issues]

Thanks Scott.  I've heard solid arguments for both, so I plan on trying both :)
