Daylight 6500K proIndustry fluorescent lamps

These D65 fluorescent tubes are built for professionals who evaluate plastics, paints, textiles and colored coatings under standard-compliant lighting. They meet ISO 3668, ASTM D1729 and DIN 6173-2 so visual matching follows recognized industry specifications.

Capacity and headroom

Each 36W, 47-inch tube delivers a color rendering index above 93 and a metamerism index below 1.0 in the visible range, keeping color perception accurate across the full spectrum. After 2500 operating hours the lamps must be replaced to maintain their tight color coordinates of x = 0.3138 / y = 0.3309.

Pack of ten and relamping discipline

The ten-lamp pack lets a facility relamp an entire viewing station at once so every tube ages together and color consistency is preserved. No additional software or accessories are included; the only operational requirement is tracking hours and swapping the full set on schedule.

Questions about this item

Will the 6500K D65 lamps work with my existing ISO 3668 viewing booth?

Yes — they meet ISO 3668, ASTM D1729 and DIN 6173-2, so they slot into any standard-compliant booth without changing the color reference.

How can I verify the lamps are still within spec after installation?

Check that a spectrophotometer reads x = 0.3138 / y = 0.3309 (± 0.005), Ra > 93, MIvis < 1.0 and MIuv < 1.5 at the work plane.

Does the pack of 10 include fixtures or only the 47-inch 36W tubes?

Only the ten 47-inch 36W fluorescent tubes are supplied; compatible fixtures and any required ballasts must be purchased separately.
