Without removing the emitter from the star that is. I tore my Lowe's Cree 2C to pieces and got the star out, but unlike the Luxeon®, the back of the star has no printing showing the bin :(

How many bond wires are there? Most of the P4's are 3 wires, if it has 4 it should be Q2 or better. Although I thought I heard they put 4 bond wires in some P4's, but I'm not sure if that was comfirmed?

Do you have any other Cree's mounted on stars, where you know what their bin is? If you had a lux meter you could take a reading with that CREE, then take a reading with a Cree Q2 and see if the reading is higher, lower, the same.

The Netherlands, yes way below sealevel
Maybee the differentiator between the Q5 and others is the tiny black rectangle on the second layer(bottom)
