Google xm-l green tint, seems to be a wide spread issue. Like I said, it's a hit or miss with the TK 41, sometimes the green will be as bad as mine, sometimes not at all, sometimes just on the lowest of settings or mode. We don't know how bad it is, but from this forum it looks like it effects 50% of their product, lol. The thing is, as consumers, we should not have to bother with testing and sending back 'defective' or undesired bins sometimes at cost to us; that should be covered in the factory inspection. And at this rate, it seems the newest lot is at best 'iffy' Haha *rant over* Love the light, just need to exchange it for a less green one.
