Mag 3D with 3 Luxeon Star Conversion idea. Comments?

[**DONOTDELETE**]

I am planning to do a conversion on a Mag 3D with 3 luxeon stars.

It looks like they will fit. They look to be a little tall for the space though. I may have to leave off the front lens (see blow re: heat anyway).

I will have to cut the pc boards on the bottom of each LS to make them fit. I will mount them on an aluminum plate and put heat-sink grease around the edge.

This will be pulling about an amp. I expect quite a voltage drop from normal. I expect to be playing with smaller resisters (that's a good thing).

I expect heat problems. I may have to leave the front glass off.

What do you think of putting two white and one amber LS in there for more brightness (as shown in drawing)?

I am ordering 3 whites and an amber today. I will post pictures and updates as I go along and eventually run times.

Any advice would be very welcome!

I'd love to see this done. I can't seem to access your drawing, though.

Squinty,

Yahoo photos can be a real PITA.

Go to your Album, load up the pic.
Right-click on it, Properties.
Select the Address URL and copy it.
Paste that in using the {IMAGE} button or the UBB-code tags.

Hope this helps.

I wanna see it, too!

Ok here is the URL drawing

I also think it sounds like a great idea. Let us know how it goes.

BTW, how are you planning to wire the LS units? Doesn't the amber LS unit run at a different voltage than the white?

I was thinking of putting a separate resistor on the amber one. I may just give each LED it's own resistor(s). I will have to play with the resistor values because the large current draw will decrease the battery voltage, and also likely heat problems.

I am going to try to find some copper plate instead of aluminum. Then I can solder the one lead that gets hot to the plate (hopefully it is the negative lead). I will cut a large whole in the plate to pass the other lead through and connect the resistor to it.

I think the LS's will be here friday or so. Cant wait!

I was wondering if anyone knew the flux output of a 3D maglite. The Luxeon LEDs sold on the arcflashlight webpage are 12.5 lumens for the amber. I'm wondering so I can compare the brightness since I have not seen one of these LEDs in person yet. I have two amber Luxeon Star/C's on order through Future-Active that are rated 36 lumens a piece. My usual use for LEDs is for my car. I have the Lumileds SnapLED 150's (the same as the cadillac deville) for my brake lights and typical 5mm (T 1-3/4) for my tail-lights. I'm going to use one Luxeon amber 36 lumen LED for each side marker light on my car. Also, which may be even better, would anyone have the luminous output ratings (in lumens) for 1157/3157 automobile bulbs (tail/brake lights).

Here are a couple pictures of my tail-lights/brake lights...

Are you going to remove the LS LED from its aluminum base? Why I ask is that you mentioned soldering the "hottest" lead to the copper plate.

I didn't know if you had seen an LS up close and personal yet. They don't have leads on them like a Nichia.

Am I missing something in your idea?

Hi Gadget,

You are right. I haven't seen one up close yet. I don't know if I will remove them from their bases. I will have to at least cut the bases to make them fit. I think there will be a problem with height clearance with the bases on and the front glass in place, so I may remove the base for clearance. I purchased one extra LS so that if (God forbid) I break one, I still have 3 to use.

Success!!! I have started a new thread.
