Osram: Difference between revisions

[[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. There are tint families for warm white (product code LCW, also includes neutral white tints), white (LW), and ultra white (LUW, others call it cool white).
