Gives an awfull lot of bright white light with a little higher colortemperature as the sun. Dazlinug and very unhealthy for your eyes to look direct into the emitter. Because this tells something about the efficience of this LED emitter it is not a cons.
You need to have dicipline to work with this kind of ledemitter. It should be handled with almost the care you need to do with a laser lightsource. Not for unexperienced people. When you give the emitter the full trottle (3000mA) you can damage your eyes propable for ever, it burns spots in your retina. Safe looking distance in bare emitter shoud be at least a meter.
Also the cooling of this emitter is tricky. The heatproduction of such a small emitter with this cuttent asks for a very efficient heatdissipation system. The star itselve is far to less for let it run on more than 300mA (so 1/10 of the nominal current.) I should almost advise TEC cooling like its is used in lasersystems. With only aluminiumheatsink it has to be big and at the place of contact with the star at least 3 mm thick.
An unbeatable emitter wich can even be used for headlight in cars. Watch your eyes and the temperature of the emitter (star). In testsituations with no safety for your eyes I advise to reduce the current to max 1000 mA. The emitter produces in that situation more than 300 lumen, uncooled not more than 300mA This is a very nice product for desighners and inventors but to tricky for not experienced persons.
