Default Need help finding a host

I bought this 532nm 200mW Green Laser Diode Module | eBay and was wondering what a good host would be to put it in. Also a heat sink

If he indeed does pay you to have one made, I will kick in 10 dollars towards it.

Yikes, you wasted quite a bit of money on that module...you could have gotten one for 5$ and it would be the exact same thing. There is no difference between those modules, regardless of what the seller has them listed for.

But if you need a host, absolutely get one from Ehgemus, his work is fantastic!

Techhoold rounded up, the output is 175-185 mw, 20% of that IR... so, really, about 150mw of green output at peak. I don't own one, this is what someone is telling me who has one. They might be binning a lot of them and picking the high output ones to sell them at that price. Many like this can easily reach 100mw and yes, can be had from the right place for just a few dollars.

I highly doubt you will get 150mW of green out of those,ever. Not saying it's impossible, just highly improbable.

@Billy- there are cheaper options on ebay, too. Should look around better next time is all
