Ok guys so a little help please. My saber is currently running a RGB Cree Coppernova (i was going to do colour mixing but changed my mind) on the red powered by a 18650 3.7v 3400 mah and is resisted at 1.2 ohm.

While the saber is bright, i would like to make it brighter, my optimum resistor was 1.1ohm so i could gain a tiny bit by swapping to that, but would swapping to a single die Cree (because of its central position) or a R/R/W Cree running both Red's improve brightness.

Or could i even under resist the current led, to 1 ohm or even lower? while i want it to be bright i dont want it to burn out.

The other option is a string blade, i can build them but i dont know exactly which LED's are best for this application or what to diffuse the light with.

Thanks
