Hi guys,
I'm having troubles getting datasheets with reflectance values for the project I'm working on.
Do you know where to find a good light reflectance index online that would be accepted by LEED?
Thanks in advance!

Where do I find the CRI of a lamp?
Do task lights need to meet all the lighting quality requirements?
How limiting are the reflectance values in the finish requirements?
Do operable shades count as lighting controls?
Does having multi-circuit lighting count as providing multiple lighting levels?
How do I calculate an illuminance ratio?
Is Option 1 achievable for open office spaces?
What lighting controls are required for a conference room with a presentation screen?

Hi Ines,
Which products are you having trouble finding cutsheets for? Maybe this community can help to find them...

Does anyone have LR values for Plyboo surfaces?

I was speaking to an architect that suggested selecting a paint sample that would match the finish and using the LRV values quoted by the paint manufactures. Does anyone have any feedback on this suggested process?

Anyone have luck finding reflectance value for CMU/concrete block or the best means for documenting this? Thank you!

Alstan Jakubiec of SUTD (Singapore University of Technology and Design) created a database of materials and their reflectance and spectral properties that is free and available online: http://spectraldb.com/
It doesn't look like they have CMU, and the "cinderblock" wall entry is a painted wall, but there is a concrete wall material (likely poured concrete), but that should be comparable:

I am having issues with the Spectraldb website. The link will not load for me. Does anyone have other recommendations for material databases?

I just heard that the Spectraldb website has been taken down. There is a plan to relaunch it, but no timeline. There are some resources in the IES Handbook for standard reflectances. There may be others out there, but that is the only one I know off hand.
