Osram Golden Dragon LED from a Uniquefire AA-S1 flashlight

Osram is a German company owned by Siemens. Their subsidiary that produces LED's is called Osram Opto Semiconductors GmbH. Osram is known for the Golden Dragon series of LED's and the OSTAR multiple-die LED's. The Golden Dragon Plus LED (similar to Cree XR-E Q5) was used in several NiteCore flashlight models. Although smaller in size, these LED's can be as bright as a Cree XR-E, but use a little more power.
