These were mentioned on this forum several months ago and were part of an ongoing discussion about the crap that LaserWorld sell.

They appear to be branching out on ebay with several resellers (no doubt to avoid too much negative feedback through the one seller).

Do a search for LaserWorld for more info, Mate.

chinesedepartmentstore.com.cn are the same. I just pulled my 500mW green apart to find it has a 300mW diode in it. Im going to do the same vid on youtube.

Hi Ben
All companies, sell their products, when the laser diode is giving
its maximum output. If a diode is giving out minimum 300mw and maximum
500mw, then, they advertise as 500mw.
It is not us that we offer it that way,we just follow the manual and
or what the suppliers indicate.
You can also see the same if you find sellers lets say on the ebay.
They offer the laser at 1000mw, while it is only 500mw minimum.

Need to send them over here where sellers sell by the laser's minimum output and the lasers are usually a good bit more powerful. How would you even know a laser's "maximum" power?

[buffo]

They are confusing the "warning label" information with the guarenteed power output rating at the maximum drive current.

Here in the US, it's not uncommon to find a 10 mw laser with a warning sticker that says "maximum output: 25 mw." Everyone knows that the laser won't actually make 25 mw, but if you put a limit of 10 mw of the label and it makes 10.5 mw, you're in trouble.

The right thing to do is to advertise a max power level that the laser will absolutely never fall below during it's rated life span. That is, if you are selling a 10 mw laser, it had beter *always* be able to do 10 mw, at least until it's very close to it's specified end of life period.

Then, if the laser is a little hotter in the begining, the customer is happy because they got a good deal. Even if the power level drops off later in life, it will still be at or above the 10 mw rating.

Most importantly though: on the warning label you make sure that the listed max power is high enough that the laser will *never* exceed it, even if you get a 1-in-a-million "hot" laser. Thus the 25 mw max power listed on the warning label in our example.

Laserworld seems to be using these three different ratings to cheat their customers. They classify a laser as "300 mw" knowing full well that it will probably only make 250 mw, and that it might fall to 200 mw after a few hundred hours of use.

In this case, they should sell the laser as a 200 mw laser, and put a warning sticker on it that says that it will never exceed 300 mw. That way, even if it makes 250 mw when new, it will still be below the warning label rating and above the advertized power level.

Too bad that LaserWave doesn't read PL...

Ehehheeh, I don't think that they do not read PL, but they just rather prefer to stay far enough from spits and rotten veggies....
