They are only $5 and the ones I got this week measured anywhere from 70mw - 115mw after slight adjustments. Even if you don't play with the pot They still have good output. IMO from talking to companies that sell the green modules, the ones over 150mw are tend to have more infrared.
Another thing is that DX has really gone down in their performance (shipping times, quality). Fasttech I have had nothing but great service with and shipment times are fairly quick.
One last thing is I don't know if it really even puts out 200mw. It might only be 150mw green 50mw IR. I could be wrong about this so someone correct me if I am.
Either one you choose you will enjoy I am just trying to possibly save you a little money :beer:
