Ebay 635 pen?

[green lasers rock]

I found what appears to be a 635nm laser pen on eBay for $9. Is this just a regular 650nm labeled as 635nm? Here is the link:

No it should really be a 635nm, others here regularly buy from that seller so they are considered reliable. A 635nm is brighter than a 650nm, I have one myself that is between 4.9-5mW and I like it better than my other two red pointers, there is a difference in color and it's brighter for the same power.

Indeed, it should be 635nm as mentioned by Alan above. Be aware that 635nm diodes cost slightly more then the mass-produced 650-660nm diodes which are known as typical reds.

That being said, eBay is a good place to get those things cheap :yh:
