[[File:osram-led.jpg|thumb|Osram Golden Dragon Plus 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 (comparable to a [[Cree]] XP-E) was used in several [[NiteCore]] flashlight models and is still used in some budget models (e.g. the Black Cat HM-01, Tank007 E07, and Uniquefire AA-S1). The Golden Dragon Plus is denoted by the product code W5AM while the regular Golden Dragon is W5SM. The difference between the two seems to be the Plus has a clear silicone lens over the LED while the Golden Dragon has flatter clear resin. However for some reason, the GDP seems to have a wider hotspot which is opposite of what a lens should do. | [[File:osram-led.jpg|thumb|Osram Golden Dragon Plus LED from a Uniquefire AA-S1 flashlight]]Osram is a German company owned by Siemens.

To make it a little more confusing, Osram has a different set of chromaticity groups that are not based on ANSI white but whose codes look very similar. These also appear in their datasheets. The regular white products only use this nonstandard approach. | To make it a little more confusing, Osram has a different set of chromaticity groups that are not based on ANSI white but whose codes look very similar.

[[File:osram-oslon.jpg|thumb|Osram Oslon Square LED]]The Oslon Square was announced in November 2011. Capable of being driven at currents up to 1.5 amps, it is a rough equivalent of the Cree XP-G, although the LED itself is a little smaller a 3mm by 3mm. The LED is binned at 700mA. The LED is binned by tints using the same ANSI scheme above. The Oslon Square EC is warm white and a minimum CRI of 80, the PC runs 4000-5000K with a minimum CRI of 70, the UW is 5300-6500K and a minimum CRI of 65. | |||
