various mW diodes for cheap

[07accordEX]

Hey everyone, Ive been using a 8x dvd burner diode for awhile and just purchased a 20x one
but i was also looking on ebay for diodes and found these to be relatively cheap do these really put out the power they claim?
200mw $12 for a lot of 5

The first three items are from Snoctony in China. He's a good supplier but the prices are for one piece, not a lot of 5. He just shows them that way. Those are 808 nM pump diodes -- faint beam and dangerous to the eye.
The last LD's at $10 each isn't a bad price but at 140 mW are a good starting point for experimenters. Probably a 12x diode.

ooh the "TO-5 package" made me believe they were 5 at first glance
how many mW would the 20x dvd burner give out? approx.

and the whole maglight/dvd burner thing whats the best way to regulate it? get a converter board or could i just add a resistor or something?

sorry im a noobie to the whole electronics thing
