Help me with this laser

ffft · Feb 14, 2014

Ok, so i just bought this laser: TOP COOL Portable 532nm Green Laser Pointer Pen Lazer Beam 5000mw High Power 301 Free Shipping-in Laser Pointers from Office & School Supplies on Aliexpress.com

And now i want to know if this laser will burn matches and if can see the beam.
I know that its a cheap laser and it isn't really 5000mW.
How many mW's do you think it has?
And whats the difference between Laser 301 and SDLaser 301?

Thanks

Don't buy this, it's not serious for 13.77 USD/piéce you have 532nm 50mW or 5mW not 5000mW

I bought it already, but whatever, its just 14,00 USD
mayber later i'll invest more in a good laser.

but do you guys think this laser can light matches?

It might be powerful enough to pop a balloon and light a match, but that laser is definitely not a 532nm 5000mW laser an actual 5W 532 would cost thousands of dollars.

What exactly can we "help" you with?

You already bought it. You tell us what's it like. Make a review.

Ask for opinions BEFORE buying. They're not of much use afterwards. Whatever we tell you now, you'll find out when the laser arrives anyway.

I believe that one of the members here, DJNY ordered several different kinds and found that the average mW was somewhere around 80 to 100mW.

You will need laser safety glasses for this power.

I also noticed that it does not come with the required 18650 battery, so you will need to get that.

I discovered this forum 2 days after i bought it, i was excited to purchase it, i won't be mad if the laser is very bad, its a very cheap one.
The "help" was to see if it light matches etc.

Tough to say for sure, but there is a chance that it will be powerful enough, and there is also a chance that it will not.

There's also a chance that it's a cheap laser but very overdriven to achieve high power, and may die after few weeks of usage.

It's always a gamble with cheap lasers. I am not a big fan of uncertainty in the final value I'm investing my money in.

Let us know. If it actually performs well and is a decent laser, it can be recommended to other people with similar budgets.
