Re: 100mW Red laser module + circuit  at KD!!

Price shows $42.53 when I look it up. It also says output power 100mW MAX. That probably means power peaks briefly at 100mW, dropping down after 3 or 4 seconds to (who knows) <60mW.

Usually when the model number is posted, you can google it and find the manufacturer or distributer..

Not a bad price though for what is being advertised.

For anyone that does not want to build their own, it is a good deal. But if I was interested, I would contact Lanling first and see if he would match the price.
