As Gunner said, the LED could be too hot for polyner's body.
One thing to note is that the advertised 270lms is hyped. Regardless, it's still very bright. Also, I bought an R2 drop in from eBay before, I sold it to another member in a few days, and he said it died in a couple of weeks :thinking: I don't know what happened. So, buy at your own risk. I've heard many members said they're pretty good, so I might have gotten a bad batch or something.
