LED help for halloween costume Answered

Can anyone help me with this. I am wiring LED's to my halloween costume and I think I need a larger power source. I currently have 8 superbright white LED's wired in series to a 9V battery. Each LED is rated 60 mA and I need each to receive 3V. I am currently using a 100ohm resister with this. This size resistor is the smallest that I had so although I don't need that much resistance, that is all I had available. Can anyone give me any advice on this setup and on how I could make it better. The lights don't seem as bright as they should be so I am thinking that I can improve on this circuit.

My advice, is that if your not sure, then look to buy a proper kit.

. <gasp> Sir! Such talk is heresy on a DIY site. Please cease and desist immediately!
. But it can be the best solution sometimes. ;)

Agreed - maybe try electroluminescent wire (search this site).

Hmmmmm, I wonder why I never use resistors in my projects unless they are totaly necessary. I would say you have limited the flow.... 9V you say? 8 superbright LeD's? I'd say the power supply may be under rated, even without out the resistor in place.
