I was unable to find much on this with a search and I hope this is the correct forum for this question.....I have a chance to get a 5 watt emitter from a co-worker at a great deal. I really dont know what I would do with it now but I thought about playing around with it and one of my Arc boards. This may be an obvious question but I never have really used any 5 watters before so can anyone tell me what it would do if I attatched this to an Arc board. I have one that I am planning to add a resistor to bump the current to about 700mAh. Would this be worth the effort or is this 5 watter not going to amount to much when ran from this circuit?...I know the 5 watters do not do well with NX-05 optics and are more flood than anything but it would be kind of cool to have a 5 watt Arc. The reason I was thinking this was my friend Owen had a TW4 long ago. This thing was incredible when ran off of one cell and I regret not ever buying one...could this idea of mine even come close to that old TW4?...anyone ever seen or done this?...once again thanks for any imput on this.
