| Prooflite 840
overhead luminaire has eight patented
7-phosphor lamps for larger viewing areas. It gives
you the longest lasting and most consistent daylight illumination available – 5000 hours! (most commercial lamps start
losing color temperature long before 5000 hours!). And after 5000 hours, they still have plenty of life left for use in non-color evaluation
areas.
What
does that mean for you?...
It
means you’ll avoid costly erroneous approvals or rejects because the lighting skewed your color perception, plus
you’ll get more lamp life from your investment. Prooflite 840 includes
our patented 7-phosphor fluorescent daylight simulation – the closest
simulation of natural daylight available in a fluorescent light source.
Not
your ordinary fluorescent technology
Commercial
daylight lamps contain only 3-phosphors, which means they have higher blue/green energy. That
could make your blue/green samples appear bluer and greener, while your red samples could appear dull. The more even the balance of color energy, the more accurately the light source renders
color. This color energy is shown in a spectral power distribution
curve (SPD).
If your light source doesn’t match the
SPD curve for natural daylight, then your ability to evaluate color is skewed. That means you could be approving color that your customers will reject and vice versa! Includes
(1) one light source. |
