I bought three pen style pointers from Amazon,( 405nm-532nm- 650nm) they all say <5Mw. The red is a class2, the green says it's a class3b as does the violet. I don't have a LPM so I can only guess at the real power. They have a company name QTECH on the label. The green can put a dot on low hanging clouds, NWS said 1500 feet that night. So any Ideas as to the true output?
They were like these just strait beam.
