That is just unbelievable!!!

So there's little kids out there with 170mw lasers thinking they have a "safe 5mw" laser, with zero eye protection?

Sometimes it's cheaper to buy the pieces separately. There were some Scientech heads on
ePay a while back and later the display portion. It was quite a bit cheaper than buying them
both together. The only thing is you need a good multimeter to do the calibration. I needed
one anyway, so it was a good excuse to buy it.

There was a thread a while back with some pictures taken with an IR camera that suggest
quite to the contrary.

Turns out you are correct, most of the time

Just received my 6 ebay pen lasers today, they tested as follows. Note all are labeled less than 5mw.

405nm#1 = 19mw
405nm#2 = 24mw
532nm#1 = DOA
532nm#2 = 55mw
650nm#1 = 8.4mw
650nm#2 = So low and dim i could not get a reading

so the 4 functioning lasers were all over spec, the green by ALOT.

FYI that green at 55mw is uncomfortable to look at dot on white wall 10 feet away without goggles. thought it was going to read higher than 55mw when i tested it but i checked 3 times and all tests were 50-60mw.
