Warnings

• Never look into the beam or into the front of the laser, even if you think it is off.
• Watch for reflections. Mirrors, glass, windows, water, metal, and other shiny surfaces can send the beam back toward you or others.
• Never look at a beam through binoculars, telescopes, cameras, or other optics. They can concentrate the light.
• Wear laser safety glasses rated for your laser's wavelength and power whenever you use it. Sunglasses do not protect your eyes from lasers.
• Blinking or looking away is not fast enough to protect your eyes from a high-powered laser.

• Never point a laser or high-powered flashlight at people, animals, vehicles, or property that is not yours, even as a joke.
• Know what is behind and beyond your target. Laser beams can stay hazardous over long distances.
• Turn the laser off before you move it, hand it to someone, or set it down.

• Never aim a laser at an aircraft or into its flight path. In the U.S., this is a federal crime under 18 U.S.C. § 39A, punishable by up to 5 years in prison and fines of up to $250,000. The FAA can also issue separate civil penalties.
• Never aim a laser at cars, trucks, boats, trains, or the people driving them. A sudden flash can cause a crash.
• Laws differ by location. Some states, cities, and countries restrict owning, carrying, or using high-powered lasers. Check the laws where you live and where you use your laser, and follow them.

• High-powered beams can burn skin and can heat, melt, or ignite materials, especially dark or flammable ones such as paper, fabric, plastic, and dry plants.
• Do not aim the beam at flammable materials, and never use it near flammable gases, liquids, or dust.
• Never leave a laser turned on and unattended. Turn it off and put it away when you are done.
• The laser can get warm during long use. Let it cool before you store it.

• Use only the battery size and type listed for your product.
• Use quality batteries from reputable brands and sellers. Low-quality, counterfeit, or poorly fitting batteries can damage the product and cause injury or fire.
• Never use a battery that is dented, swollen, leaking, or has a torn wrapper.
• Read our Battery & Charging Safety guide before you charge.

• Do not open, modify, or repair the product yourself.
• Stop using the product right away if it is damaged, overheats, flickers, or behaves unusually. Contact us before you use it again.
• Store it in its case, in a cool, dry place, out of reach of children.

Our high-powered lasers and flashlights are intended for responsible adults, such as researchers, professionals, and experienced users. They are not toys and are not intended for anyone under 18.

• Do not let children use or play with our lasers.
• If you give a laser as a gift, share these warnings with the person receiving it.
