Ridiculously powerful laser pointers - from China.

[tasseltine]

Hi

I recently saw a laser pointer for sale from a supplier in China that seemed absurdly powerful. It was a 20W blue laser pointer. It cost a few hundred dollars, and did look fairly imposing, more like a lightsabre than a normal pen size pointer - and it came in a metal box with goggles etc. But can such a thing be genuine?

They claimed to have free shipping to the UK, though I did wonder if HM Customs might have some additional "charges" to add.

It was billed as a 20000mW blue laser.

I'd be very interested to hear what people think

Cheers

Tass.

You ain't getting a 20W blue laser for a few hundred dollars. Would need to start talking thousands before it would even be considered. Most likely a typo for 2W/2000mW

Most likely a typo like @Things said! :beer:
Can you give us the link..? :thinking:

Hi

I thought it must be a typo - though they mention it several times.

Here's the link:

Wholesale - 20000mw blue laser pointers 450nm burning match/cigarettes/wood5 capsglassesbatteryc, Free shipping, $359.48-414.86/Piece | DHgate


There's more than one variety on that site. As you say, it sounds like it must be rubbish - but I wondered what you all thought.

Cheers

This host is often used for 1W lasers. I guess forum members could squeeze even 2W into it. I mean efficient diode, good driver, good heat dispersion discipline. But 20 is typo for sure. Not so uncommon on these sites.

it is hard to imagine it's a typo when "20000" appears on the page numerous times. Isn't this yet another unsubstantiated claim we often see from "over there?"

You can fully trust DHgate :crackup:

 

[DrSid]

Well I meant "typo", not just typo.

If it had that kind of power you would think they would advertise it as being Abel to set trees on fire / cook cows standing in the field/ shoot down the satellites :crackup: . Id think twice b4 I bought from them !!

They also have a 10000mW version I don't think it's a typo and not to forget the 3W 532nm :crackup:

OMG A 500 MEGAWATT 532nm HANDHELD :drool:

Would love to have ANY wavelength handheld laser at 20W that can run on 2 chinese 16340 cells.

 

[Teslanium]

:wtf:

And I'd love to know how many seconds (or fractions thereof) of battery life you'd get! :crackup:
