Why are 405nm diodes 100mw and above so freaking expensive? I can find 20mw-50mw all day long for around a dollar, or two. That's new and use. Just scored 20 pcs of 405nm at 20mw for 8 bucks. I spend a lot of money with a certain surplus laser store, and they return the favor by sometimes giving me sweet deals on things I want. For the life of me I can't figure out why above a certain mw range they just go crazy in price. I really like the violet color, but for my old eyes, maybe yours too, it takes a bit of power to make that dim color light up better. Anyone know where I can get a sweet deal on some 1000mw+ 405nm, like the deal I got in the text above. $40 to $100+ just doesn't cut it for that tiny 5.6, when I can get way more powerful diodes for cheaper, just a few nm's higher.
