what is the cheapest 1w 520nm handheld?

[NightExplorer96]

I asked my manager,she told me this is a laser module,not a laser diode.also the price is wrong.Thank you,I will delete this product information.

What is the correct price for a 500mW 532nm module? Im curious!

Hi Jessica, we always welcome high quality reliable companies - but it is hard for us to trust unknown [to us] companies.

You say on your messages in your profile: "We are a laser diode and laser module manufacture in China over ten years."

Yet this is inconsistent with the company information on aliababa: "Year Established: 2010". [which is only 4 years not 10+]

And on your site dglanji.com [google cache] it says "Dongguan Lanji Photoelectricity Co., Ltd., founded in 2006," [which is 8 years not 10+]

Consistency helps to build trust.

Chris.

How are we supposed to buy there? (never use alibaba before, only aliexpress)

If this is the right price I'll surely order one to see if it's real.


BTW, seems like they have found a projector to pull the 1W 520nm and the 3.5W 445nm - perhaps the time has come for their prices to drop!

You're cute Jessica but it seems that most chinese companies don't know how to label their products correctly. I hope you can fix those mistakes on yours.

Jessica, why do you have a lot of listings for the same diode with different prices? Like

This makes no sense at all.

As for brightness. If your 270mW laser is a 520 as well a 1W 520 will be roughly twice as bright because when power quadruples brightness gets doubled.

Isn't it power squared doubles brightness?
