Dedomed MagLite LED.....ITS BLUE!

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 :wink: 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 :smiley:

Since someone is probably interested, photos!

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.

Hmm iirc if phosphor is ripped off with the dome then you get blue.

Yeah when I looked at the dome closer i saw a square layer still on it…….does it damage the life of the emitter at all?

No, but the blue light causes your testicles to shrivel up and drop off… J)

You spend a lot of time shining your flashlight at your testicles? S)

Doesn’t everyone? :party:

Red and green this time of year.

isn’t there a problem with UV emissions without the phosphor? (just asking)

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?

I kind of like the blue result above; it’s a bit ringy, but the color looks nice.

Acetone does a great job in removing the phosphor IIRC.

+1 on acetone.

Take the discarded tail of a zip-tie, cut it at an angle to make a non-scratch tool for cleaning up any leftover silicone or phosphor.

(edit: I did not use the non-scratch tool on the above LED... obviously :))

Its ringy cuz maglite reflectors suck like something awful

Joking aside, blue light can cause eye damage.

White light or blue light otherwise mixed with other colors seems to be of much less concern.

Human studies haven’t been conducted since subjecting people to conditions that can cause permanent eye damage is kind of frowned upon.
