| Well, It really depends on what surface you measure this on. Like, on a black thing, it will be much hotter than on something white. But in the air, it would be even less. |

| Thanks Yathern, but i´d mean if it´s acually possible to meassure the beam, not the surface of the impact |

| I may be wrong, but I don't think it will be that much higher than normal. The light just passes through, so the air is absorbing very little energy. So the beam itself won't get very hot. |
