I have some part numbers for lights available in the asia-pacific
region.
TLD58w950 = TL-D De Luxe 58 watt 5300K.
The website is
http://www.apr.lighting.philips.com
Click on Product Catalogue
Click on Lamps
Follow the browse steps to the fluoro TLD range, scroll down to find
the TL-D 90 range
They quote a rendering number R a >95, I assume this is the same as CRI?
Don't know if they use the same product codes in the US.
By the way,
I measured some Hitachi AAA tubes with i1 and i1share the other day.
The lab manager told me they were supposed to have a rendering index of
99 and a temp of 5000K. I measured 4830K and a rendering index of 96.
Do these figures indicate old lamps or is a quoted figure of 99 a bit
optimistic. I also can't find any info on these tubes anywhere. Any
comments?
Thanks,
Simon
