In that case the LED module is likely pushed up against the switch and secured by the blade. The module itself is as described before (LED on heatsink hot glued to diffuser) but in Ultrasabers they are pretty much "free floating" which is what allows for the Quick Disconnect feature. Someone you might want to PM on the matter is Master Caine as he is quite knowledgeable and usually willing to help when he can find time (He runs a prestigious martial arts school and JUST had a daughter born to him!). Otherwise you can email
shipping@ultrasabers.com and see what they will tell you. Deep can recommend parts, which LED module you want to use, though you already know that and how the parts come together. Heck if you aren't skilled in soldering and electronics you can ask about the possibility of sending your hilt to the shop to get outfitted.
