There are many different types of disco and DJ laser lights used in the entertainment industry. Some lights are more powerful and brighter than others but overall not harmful. Most lights like Martin, Chauvet, ADJ and other professional lights, are regulated by the FDA, CE and MET. With these approval markings on a product, the manufacturer ensures that the light conforms with the essential requirements of compliance. However, there are consequences from direct light exposure. This powerful beams may overwhelms the eyes and cause over saturation of the retinal pigment and thus, cause flash blindness. Flash blindness is a temporary visual impairment following exposure to light that may last from a few seconds to a few minutes. As the pigment returns to normal, so does the sight. Temporary visual impairment caused by light or strobes can be more severe on the handicapped, and may lead to photosensitive epilepsy and seizures.
There are very strict regulations imposed by the FDA that ban dangerous lasers. Most of the professional DJ lasers follow compliant safety rules that include the use of internal filters to protect from laser hazards. The architecture of the laser will safeguard individuals from certain radiation limits. The FDA provides specific manufacturing regulations that set emission limits to the lowest class of radiation exposure for lasers or light emitting products. There are different regulations for medical lasers than for DJ lasers. A DJ laser is consider a safe Class 3R laser with restricted beam exposure.
Like with any other beam of light, DJ lasers are safe as long as you avoid direct long exposure. Similar to disco or DJ lights, laser lights can cause flash blindness with direct contact. The temporary loss of vision can be compared to looking directly into headlights at a close distance. Your vision will quickly come back as the isomerization process is reversed.
If you are employing a DJ or company that will include a laser light show, make sure his/her lights are of professional grade. Using unreliable brands and lasers can be dangerous. Many of the non-professional grade lasers may lack the filters use to attenuate hazardous beams that give off dangerous levels of IR. In order to ensure that you are not exposing yourself or your guests to an eye damaging beam, you must inspect the laser yourself. If it doesn’t have a power or key switch, it is not a professional grade product and must not be used. MOsDJ is also a professional DJ equipment retailer.
