So I picked up two MagLite 2D LEDs from Lowes the other week since they were $14 each. I wanted to see how tough these buggers are so I tossed in 2x 32650 cells to see if I could blow the driver……no luck so good job MagLite. Next I figured I’d try a “ghetto” dedome and see what damage I could cause. What is a “ghetto” dedome you ask? Well one take a knife and two rip the dome off Dome came off “cleanly” from what I can tell (cant find my macro lens so im working with helping hands and a point and shoot camera. Bond wires still look in take and I dont see a layer of the dome remaining.
Pop 2x D cells and and BLUE!!! I kinda love the blue/purple tint to this and want to pop the dome off the other one but wondering how long the LED will last with this method of dedoming? Im guessing the tint shift is due to either removing some of the emitter when the dome came off OR a layer is still over the dome. Anyone have experience with blue dedome tints and how long the emitter will last? Nbd if it dies since ill scrap the guts and turn into another 2x 32650 laser
You ripped off phosphor the layer that converts the blue LED light to white light. On same early LED designs the phosphor was mixed in with the dome material.
I don't know what's actually coming out, but de-phosphored LEDs will make your eyes sting after using them a while. Probably not as dangerous with just a little XP-E at the Mag's stock drive current but my naked XML2 & MTG2 are both truly evil things.
Soooo... next question is, Does anyone have a way to strip the phosphor from an emitter? Sounds like it could be fun... Gasoline-soak to remove dome, ???-soak to remove phosphor without damaging bond wires?
