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.
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!)
