I'm a newb, trying to learn as much info as I can before I embark on building my own saber.
One thing I noticed in my reading of this forum is that often times a particular LED will be deemed unsuitable for sabers. I can understand if their efficiencies are not very good, ie lumens/watt. You clearly want the most efficient, right?
So then why wouldn't this led be suitable? Granted its only white, but 430 lumens at 350mA is pretty good, no? I've seen posts about a P7 that produces 900 lumens at 3000mA. But that cree led I linked to is way more efficient. Is light output linearly additive? Can I put 3 430 lumen leds together to get over 1200 lumens at 1000mA? Or even just 2 together to get 860 lumens at 700mA is darn good, no?
The other things I would imagine are factors are heat, but as a corollary to efficiency, the more efficient a led is, the less heat it should produce right?
So what other considerations are there for determine whether a particular led is suitable?
