I have the TFO's also, and I don't know of any that are brighter, not that would work on a pistol anyway. However, I did pop the tube on the front sight, and the gas gradually leaked out, which made it dim down at night. But they were still under warranty, and I got a replacement from TruGlow for free. So, if they are damaged, they can dim down to pretty much nothing.
