Default SHEFI 304 green lasers from AliExpress

Anyone have any info on these lasers. I am trying to figure out if there more powerful then the 303s and the 301 lasers in general. Not sure if its worth my time to buy one and test it. It looks a little nicer then the 303 and 301 lasers and has a led that lights up when you turn it on.

Default Re: SHEFI 304 green lasers from AliExpress

I seriously doubt it is better than a 303. It states it can light a match if it is focused down to a small enough spot. If you decide to get it, please measure its optical power. I would like to be wrong about this.

As Paul said, it may not be more powerful than the 301/303 lasers, but for $25.00 you're not out too much if it's only on par with them.

I agree with you that it looks a little nicer, and as a plus, it does have the led and a key switch.

Worst case scenerio, you're not impressed and you build something nicer into the host!

Maybe a 500mw 808nm pump diode, so you are looking at a 75-125 mw 532nm but at that price I would bet they are the lowest spec units, think lots of waste heat and about the same 50-75nm green you get in an ebay HH

That host looks good for $25. Worth taking a chance but would not expect any 500mW output for that price -- maybe 50mW to 100mW

Seems like I remember them being slow at getting your item to you. They aren't anymore trustworthy than most eBay sellers. Depending on the item, sometimes less so.

Damn! I wouldn't buy from them either if they did that to me. I do usually use PayPal though as the Chinese seem to like it.
