i pried loose the lite-on open can from its heatsink attacking it from the bottom side. there are several small indentures on the back of the heatsink where the diode base is---removing the glue there and pushing the base up with a small screwdriver symetrically on all sides should pop the diode out with little effort.
however: i read somewhere on LPF that the lite-on LD had the short-chip open can. I cant tell that for sure as im not able to see the chip of my specimen, but what i do know fora fact is that it has a higher voltage drop across the junction compared to my two LG diodes. The lite-on has 2.51V at 150mA, whereas LGs have 2.38V at 180mA. I dont know how this relates to output power handling/delivering capabilities of these diodes, but it is obvious that they are not identical.
