  1. Osram Sylvania / NIST Update Effect of light source intensity on object chroma 12 spectra composed of same RGBY combination

  2. Osram Sylvania / NIST Update Loss of chroma in greens and reds is largely responsible for decreases of CRI across these sources. Originally planned for sources at 350 lx, 220 lx and 150 lx, but we’ve decided to just one pair of source intensities. Source 11 Source 5 Source 0

  3. Osram Sylvania / NIST Update As we were trying to select source intensity pair, we started to have concerns about the stability of sources, so we stopped to address that first.

  4. Osram Sylvania / NIST Update Maria and Bob measured spectra 6 & 8 from each source over the course of at least two days at 150 & 500 lm Stability looked good

  5. Osram Sylvania / NIST Update Resuming experimental preparation: We’ve decided to use fake food & place setting as the naturalistic scene Meeting again July 2nd to choose the two light source intensity values Plan to run subjects this summer

  6. Osram Sylvania / NIST Update Original Timeline: Experiment Set-up – October/November, 2007 Tests – November/December, 2007 Maria wanted to get it done before she had her baby. The timeline was too ambitious for us and the baby arrived. She is now back from maternity leave.
