Good work :twothumbs , i must get round to making a few of them like that for a few of my older lights.

well done!
There's only a few individuals on the forum that can install an entire driver circuit in a PR can, apparently your one of them:thumbsup:
Which schematic did you use?
Any build photos?

Re: I moded a incandescent bulb to Luxeon ..
I could do it with a resistor , but this is Direct drive ..
Its for my old 1970's 3D flashlight .
I haven't tried it with fresh batts , what I generally do is run my 3Dmag till it gets weak , then swap the batts into the 70's tin wonder , it had a 1W LED bulb in it that put out with used batts , so I figure I would try a left over Luxeon LED , if it fried , no loss , but it works real well . An incandescent bulb is dull yellow and you can hardly see anything with it in the dark , this thing puts out like an incandescent on fresh batts , its more than twice as bright on dead batts than the 1W LED bulb I got .
D's being expensive , I want to suck every mA out of them before discarding . + I was thinking of getting some Nicads 3x1.2v = 3.6v [ so should be fine for DD ]

No . its a no name made in Taiwan 1970's Tin 3D .
I actually purchased it in the 70's New [ My first flashlight ] , and have kept it for some 35 years . Im still thinking of a way to do a high performance [ R2 ] mod , that wont spoil the light .
Hmmm , perhaps Luxeon K2 TFFC ? Bulb mod ? But the heat ? How to get rid of the heat .
I should have taken more pictures : The mod is pure genius in simplicity .
Whether it can handle 3 fresh D cells ?? 2 D's would probably be ok . as it would be under driven , but fresh cells and 4.5v , I just wonder if it could handle the heat . Oh well , works well with depleted cells , which is what I wanted .

Came from flashlight claiming Luxeon LED ...
Whoa - Ok ... All my older lights were supposedly Luxeon , and I think your right ... After a closer looksee , it looks seoul !

Naa wont turn blue ...
I actually soldered a bolt to the bottom of the LED , then fed the bolt through the bulb and used a rubber washer and a nut to hold in place + epoxy glue .
The bolt is the heatsink + the positives terminal , negative is to the bulb body .
I then used a hand held motor tool to grind the nut and bolt at the bottom to shape .
Extremely simple in design , and easy to execute .

Re: I moded a incandescent bulb to Luxeon ..
Thank you , Ive seen his work ..
I think ill leave it as is for now , it does what I want it to .
If I ever find a similar light , I might try something more radical .
