An H3-antihistamine is a classification of drugs used to inhibit the action of histamine at the H3 receptor. H3 receptors are primarily found in the brain and are inhibitory autoreceptors located on histaminergic nerve terminals, which modulate the release of histamine.
Burning paper requires 1 watt (1000 mW), which is more than what most laser pointers can achieve without modifications For comparison: Popping balloons or lighting matches râ¦equires roughly 100 mW (which is the high end mW range of most commonly found laser pointers) Note: laser pointers anywhere near 100 mW and up are very dangerous to the eyes and ...
The most dangerous laser classification, Class 4, begins at 500 mW (1/2 watt) for visible light. Class 4 lasers can cause instant eye damage, skin burns, and can be a fire hazard for certain materials. The new devices are four times the minimum for a Class 4 laser. A 2000 mW laser is an eye hazard up to about 1,000 feet away from the laser.
