Honestly, im not sure how well it would work. With the leds used in current sabers, theres really no need for this.
Compared to the string blades like master replicas sabers have, okay yes it would be an improvement.
However sabers built using the polycarbonate blade and p4, lux, rebel star, LEDengine etc we already have fully duelable sabers that are very very bright as it is.
You can get a grab bag saber without sound for basic dueling from ultrasabers and its pretty much nuke proof. For something more shiny that can be used for display and costuming as well there are many sabersmiths out there that make absolutely gorgeous pieces of work.
The other thing is, with these bulbs being designed to replace flourescents, it likely needs far more voltage than we can really fit into a hand held unit.
