musht Posted July 1, 2009 Share Posted July 1, 2009 Fairly sure its normal blue, be aware Lumileds colour binning is somewhat wide, what still makes the blue bin a lot of people would call green... Link to comment Share on other sites More sharing options...
tomy364 Posted July 1, 2009 Author Share Posted July 1, 2009 I have problem with palco 3 of 6 units which I have bought before 3 years and with 8 units which I have bought before 1 year because in new version of palco 3 are blue color much stronger than in older. When you mix rgb color you get different colors so I have idea to upgrade older version with new blue luxeon diodes but I`m not sure which color is. You say that is blue 470nm ???

musht Posted July 1, 2009 Share Posted July 1, 2009 Need to become bit familiar with this data sheet: http://www.philipslumileds.com/pdfs/AB21.pdf Page 4 is colour bins for blue, as you can see Luxeon blue is acceptable to them from 460 - 490 nm , 490nm bin 6 is really cyan , very green for blue. Some bins are just never available, some you`ll have to wait for or pay a premium on. You are very unlikely to be able to match exactly all the units, aging will have affected all the colours , mainly brightness colour itself dsent shift much. That and trying to get a bin colour close to what you have, its like wallpaper batches are always slightly differnt from each other. Link to comment Share on other sites More sharing options...
Germaine Posted July 2, 2009 Share Posted July 2, 2009 Apologise if I'm stating the obvious but according to the people who flog these the apparent difference in color in this range which most people put down to the 100'000 half life of the LEDs has more to do with people messing about with the balances in the menus, has this been done/tried? I know you'v not mentioned half life but I still think checking and playing with the master settings would be a much cheaper start. Assuming you haven't done so already?
