RE: "Hardware Store Tubes"
Hello Eric, Thanks for your reply. Of course I am familiar with the new revision of 3664, it was a hasty email on Friday afternoon and I should have offered more details to be clearer. I am interested in 'Hardware Store Tubes' not so much for critical viewing but rather to use in a factory nearby presses and other areas where colour critical appraisal will be conducted. At a plant last week i used Babel's CT&A to show a customer lights on all their presses needed updating. Around the press area all the 'industrial tubes' are old and yellow and I was able to measure them and deduce these tubes were in fact influencing the results on the press console. I thought if there was a off the shelf tube at a reasonable price, which does not too badly influencing the critical viewing area, it would make sense to use these tubes in the areas surrounding the presses. It might be the model mentioned was "Philips TL-D-90" Anyone using a specific specification for around the presses, but not critical viewing? Regards, Dan

Hi Dan,
With the revision to ISO 3664:2009 and the tighter tolerances required there are no off the shelf tubes that are accurate for color viewing. There might be people out there that will advocate otherwise but this simply isn't the case. I'd be happy to talk with you about this in more detail if you prefer.
Regards, Eric

Hi Forum,
Attempted to find this information searching the ColorSync archives but that was not as easy as I hoped.
I recall someone reporting on their testing 'off the shelf fluorescent tubes' for use in colour viewing.
I even recall a screenshot of the specifications printed on the Tube.
Can't find it anywhere on my computer :(
Is there an 'off the shelf fluorescent tube' that performs well?
Thanks in advance,
Dan Wilson

Maybe this can help. Don't know if cheap enough. http://www.dickblick.com/products/lumichrome-full-spectrum-fluorescent-lamps...
Would they meet the ISO-3664:2009 requirements? Still, interesting alternative...

Hello Roger: "Helps With Calcium Absorption.", and "All Birds indoors Need Some Type Artificial Lighting." CRI 96, 95 or 98 for 5000, 5700 and 6500º Kelvin respectively. And a graph of SPD http://www.mmlights.com/Lumichrome%201XZ.html As Dan said, the Philips tubes are cheaper. Jose Bueno
Jose, Thank's for the additional information. I wonder about the graph of the SPDs though? The width of the bar does not say much about the shape of the light, which should be a little more "spikier" that what they show? Still, I'd like to find detailed information on these lamps.

This page has a spectral curve - spiky as you might expect. If your main goal is to match color temperature for surround lighting, almost any of the high CRI tubes probably will do. If you want lamps per international standard for viewing output, then likely none of these will be guaranteed. -----Original Message----- From: colorsync-users-bounces+waynebretl=comcast.net@lists.apple.com [mailto:colorsync-users-bounces+waynebretl=comcast.net@lists.apple.com] On Behalf Of Roger Breton Sent: Sunday, August 05, 2012 12:53 PM To: 'José Ángel Bueno García' Cc: colorsync-users@lists.apple.com Subject: RE: "Hardware Store Tubes" Jose, Thank's for the additional information.

I bought a couple of 'Hardware Store Tubes' a while back that don't seem to bad: NEC 5000K Quad-Phosphor T8 FL40SSEX-N/37-X and this is what I measure using an i1pro2 (note the tube is not new): Closest Daylight is 5001K with an error of 2.9 Delta E CRA 81.9 The UV content is almost certainly too small to meet the current ISO standard (not that there is any way to directly measure that with a graphic arts type instrument!)

For many types of CFLs, LEDs, LEDs in FL sizes, Halogens, LEDs in Halogen sizes,and more check: http://www.olino.org/us/ov/lamps Their test results show much more than the CRI numbers. -- Met vriendelijke groet, Ernst Dinkla Grafische Techniek Quad, piëzografie, giclée www.pigment-print.com
