140mW is about max you want to use if you are using a 16x DVD-diode, like from Senkat. The Dorcy-driver with no resistors and a 3v battery will supply about 350mA with an intial “spike” up to 400mA, this will kill a 16x. An “open-can-DVD diode could handle this current for a long-time, it would put out more like 200mW, you should still use at least a 1-ohm resistor.
To produce more current you can use a 3.7v battery, but make sure you use the proper resistor-pack to limit the current to a safe level for the diode you are using, this combo will go over 500mA, few diodes can take that for very long.

think ill stick with 140mw...lol..... what is the resistor pack?is it the lil 6ohm thing that he soldered to the diode in the video?[/quote]
That is a good idea for your first build. The resistor-pack is what Kenom used to limit the current going to the diode, in his case 6-ohms. You can place it anywhere in the circuit, (in series), but the positive-side of the diode is best. I "surface-mount" my resistors to the power-distribution board, same thing, just a different location.

hmm... so i would take out the bulb... and solder the diode to the same spot... and cut the board for whatever it does. should i use that glue stuff like in the video or can i just use a hot glue gun?... still waiting for the dvd burners... might be a week er 2.... i should be able to get my dorcy jr., the lil 6ohm resistor, the module with the batteries, and i can't think of anything else i would need. is there?
