How do I know if I have a too-powerful laser pointer 5000mw
According to the Food and Drug Administration, which regulates laser pointer 5000mw, about 60 percent of lasers they tested in 2018 were over the power listed on the label — or the label did not list a power level. Lasers called “pointers” or sold for pointing, are required to be less than 5 milliwatts in the U.S., and less than 1 milliwatt in countries such as the U.K. and Australia.

These are tips from FDA on how to tell the strength of a handheld laser:
If the pointer is small and runs on button batteries, its output probably is less than 5 milliwatts.
If it's pen-sized and runs on AA or AAA batteries, it's likely to be more powerful and may exceed 5 milliwatts.
If it's flashlight-sized and runs on a cluster of AA or AAA batteries or runs on lithium batteries, it likely exceeds 5 milliwatts.
Pointers sold with battery chargers probably drain their batteries quickly and are likely to be overpowered.
Some pointers are sold with a removable cap that spreads the beam into a pattern. If used without the cap, the beam becomes a single beam that could exceed 5 milliwatts.
Look for keywords that sellers might use to indicate a pointer is highly powered without saying that it's over 5 milliwatts: powerful, bright, ultra, super, military, military grade, super bright,high power laser pointer, ultra bright, strong, balloon pop, burn, burning, adjustable focus, lithium battery, lithium powered.
Look for videos or photos that show the laser burning, melting, balloon popping or show a bright, well-defined beam of light
Look for purchaser comments on websites that tout the brightness or power of the product.
