Fujitsu Semiconductor has introduced a range of 8-bit microcontrollers with embedded flash memory.Start to look into LED lighting and quickly it becomes obvious that one type of LED will not suit all situations.
After a while, you get sophisticated enough to take colour-rendering index (CRI) and colour temperature into account, and even then you are only about halfway down the check list.
A little colour science
There is no scientific definition of white light because, like beauty, white is in the eye of the beholder.
Philips has won a category in the US government's competition to demonstrate the highest efficiency high quality lighting.

Ian Bryant
Ian Bryant is Business Development Manager LED Division at Carclo Technical Plastics. He has worked on and off at Carclo (Formerly Combined Optical Industrial) since leaving school. He has worked through the company from Toolmaking to starting the company on the road of LED optics business some 6-7 years ago, starting with a standard range and more in line with the business of custom optics. In between all this he has worked in engineering and as a works Director for a hydraulics company but kept getting pulled back to the optics industrial. We are able to offer the full solution from idea to parts so have a very good understanding on what is needed. You will see some posts from our design team also under my name.
