@Winfield Hill: ditto, I would love to see a detailed datasheet. Blurbs like these do nothing other than announce a product! @Ryszard.Milewicz: I suspect it is a solution with strips of LED arrays spaced as needed by packaging/thermal considerations and not individual LED chips. That is why it may be difficult to add other wavelength light sources you describe. Either way, the trick in containing thermal issues in an array of LEDs is to switch & drive each/groups of LEDs alternately so that the light output remains the same while the temperatures can be contained.

As this is multi-chip package, adding some amber chips inside package should improve warm white efficiency up to cold white levels (as currently Osram did).

Wow, small 46-volt 6-watt LEDs, cool! Hey guys, the link doesn't give us the datasheet we're craving, but merely a 2-page blurb. How about also including a link to the manufacturer's web page in your stories, that'll help us get what we need. You know, like http://www.cree.com/
