Some lasers are more powerful than the labeled or advertised power

532nm green laser diode module

Some Laser Sights for Handguns 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 mW.
Sellers promoting high-powered laser pointers may use words such as: powerful, bright, ultra, super, military, military grade, super bright, high power, ultra bright, strong, balloon pop, burn, burning, adjustable focus, lithium battery, or lithium powered.
Videos or photos that show a laser with a bright, well-defined beam of light burning, melting, or popping balloons are probably Green laser 50mw that greatly exceed 5 mW.
If comments posted on the website describe the brightness or power of the product, then it likely exceeds 5 mW.

Some lasers are more powerful than the labeled or advertised power. If you are not sure if your laser pointer is a high-powered laser, consider the following:
If the1mW Laser Pointer pen is small and uses button batteries, its power is probably less than 5 mW.
If the laser pointer is pen-sized and runs on AA or AAA batteries, it's likely to be more powerful and may exceed 5 mW.
If the laser pointer is flashlight-sized and runs on a cluster of AA or AAA batteries or runs on lithium batteries, it likely exceeds 5 mW.
Laser pointers sold with battery chargers probably drain their batteries quickly and are very likely to be overpowered.
Some laser 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 mW.
Sell​​ers promoting high-powered green laser 300mw may use words such as: powerful, bright, ultra, super, military, military grade, super bright, high power, ultra bright, strong, balloon pop, burn, burning, adjustable focus, lithium battery, or lithium powered.
Videos or photos that show a laser with a bright, well-defined beam of light burning, melting, or popping balloons are probably lasers that greatly exceed 5 mW.
If comments posted on the website describe the brightness or power of the product, then it likely exceeds 5 mW.

 

100mw green laser pointer

If users have no experience with red dot laser alignment, users might never know how efficient this laser tech applied dot measurement tool will be in industrial dot generation work. This advanced 650nm red laser diode tech applied laser alignment makes the best utilization of 650nm red laser diode technology. Available with super bright and visible red reference dot emitting, this dot projecting laser alignment is widely applicable for dot measurement in laser marking machine, laser engraving, and button positioning etc. The noncontact red reference dot can always go through for miles far away in distance, and just getting the best dot generation on all targeting surfaces as efficient as possible.
