I've just bought an old set of lights (Ay Up) which probably date from around 2007 or 2008. From what I've been able to find out Ay Ups have been manufactured with different types of LEDs including Luxeons, Seouls and Crees. I'm curious to know what ones are in mine. Is it possible to identify them? The lights are sealed, so I don't want to disassemble them even if that were possible.
