Tactical flashlight. They're strong enough to give you second degree burns if you hold it against your flesh.

They typically have low, high, and strobe modes for disorienting targets.

They also usually have the most asinine single button interface and the most likely person to get strobed is yourself lol.

Second degree burns, lol. I have a couple of those "tactical" flashlights. They don't put out nearly that much heat.
