The problem will be that it's not in a star format. There probably are no available optics for an led that shape. My guess is that since they say it can be used for headlights, it is bigger than anything we can use for sabers.
The Seoul P4 or the Cree type leds are white and they pack a punch! They are brighter than their advertised lumen ratings.
Besides, it most likely takes as much power as an Atlas led.
There is a formula that Do-Clo once stated, but I forget. It regards balancing battery space, led type and a driver/whatever, into a decently sized hilt.
Look at the last saber Do-Clo made with the Atlas led. That thing is huge, due to the massive battery power it requires.
I read that new led needs 8v of power, but remember; If it dosent have optics available, it is usless to us. Flashlight guys will love it though.
