You're right. Without an LPM I won't be able to find the power. But there is still an obvious difference between 10mw a 100mw.Without a LPM you would most definately not know the power of it. My two $5 405nm ebay pens are doing 84mW and 95mW each. A $5 "toy" is doing almost 100mW and to the eye it looks weak as heck but that's due to the wavelength charateristics. Sorry but w/o a LPM you can't tell me what power they are doing because its physically impossible to know
