I finally laid my hands on a CR2 Ion---my only CR2 based light. After playing with it for a night, I just can't resist the urge to mod it. Here are some ideas:
1) The XLamp-based light source and the nickel-plated conical reflector put out more of a flood than throw. However, for a small EDC light, I would like to see more throw. In this way the light is not limited to indoor/in tent use.
2) The setting of the two-stage switch is not where I wanted. I would prefer reducing both the high and low settings. Since the perceived brightness is proportional to the square root of the lux number, I can reduce the power consumption by half and only lose ~30% of the perceived brightness. Combined with a more focused beam, the actual brightness should hardly change. But the runtime will be extended to ~3h on high and almost two days on low. This level of long runtime is important for a small EDC light, because then you don't have to keep tracking the usage, and know there will be useful level of light available at any moment.
Now the tough part---
The construction of CR2 Ion bezel looks like two pieces screwed together with the help of some glue to keep them together. Has anybody tried and successfully opened up the two pieces without distorying the beautifully-finished parts? It is a fairly expensive light after all.
Does anybody know what converter IC is used in the CR2 Ion?
