Thanks ... Was hoping you could give us something with more detail - maybe a view of the back of it - that's usually where any identifying marks are found.
No numbers on the packet or anything?
From that picture/angle it could be just about any closed can 5.6mm diode. They all look the same pretty much ...
Perhaps you have an e-mail from High Tech Dealz detailing what was in the order? Assuming you bought it directly from them.
Looking at their site - the only diode they currently sell in that form factor is a 1W 445nm - Probably the original ca$io diode. That said, perhaps they sold other diodes at some point? No point in assuming it is that diode without many more facts ...
Does your diode have solder on the pins or anything?
