aspherical ?

[jamie.91]

Firstly, sorry if this is in the wrong section:candle:

secondly i am a newbie('ish) so bare with me

ok so today i went to the scrap yard (im from the uk) and came across a ford mondeo which was stacked on top of another car and as i walked by something caught my attention, so i take my screwdriver and break the foglight out then start to destroy it "carefully" and it turns out i was right, inside is an aspherical lense. so over the moon i walk away with it.

so now we get to the good part, for quite a while i have wanted to do a "good" mod on a light (BTW awaiting delivery on a romisen RC-N3, my first propper light) so my question is

Does anyone know of a light that preferably runs of a single or maybe doubble if need be 123A that will house my shiny new lense that has a dimension of 147.30mm width ?

any help would be hugely appreciated

my plan is as follows:-
-Cheap host (123a and a tail clicky)
-EDC'able or slightly larger in size
-hopefully similar to the RC-N3 or D-mini in appearance
-head with a larger diameter than that of the body
-my shiny new mondeo fog light aspherical lense

And the exiting part, an LED and current regulator reommended by YOU lol

i think a cree emitter would be best ?

thanks jamie

Hehehe..150mm EDC

That's kinda wide, the Maglite is a bit larger then 50 mm in diameter. Not what I would consider EDC able, so 150 mm would be even less EDCable. I don't know of any hosts besides maybe one of the smaller "X million candlepower lights".

I'm thinking some 6 inch pipe, an extra-bright incan, a SLAB(sealed lead-acid battery) and a military ammo box would make for a real nice "portable" light

Looks like you need to recalibrate it. Looks more like 50-52mm which should fit into a mag.

the focal lenght of such an automotive lense wille be too wide to be useful,
but Your results are greatly appreciated

 

[DM51]

Interesting project. As saabluster says, that looks like ~50mm (~2"), not 150mm.

I'll move this to H&M.

Have you measured the focal lenght?

You need to look at a thread posted by DocD

He too uses a lens from a Ford BUT its 67mm
If your lens is approx. 50mm have a look at a Maglite, it might fit in there
but as mentioned above, whats the focal distance.
If the focal distance between the lens and your emitter is correct, then you will be able to project a SHARP image of the die ( ie brightest hotspot)

The brightest spot isn't when the die is focused. It's a few mm further away than that. Focusing the light from the dome (which collects more light than the aspherical lens) is more efficient and considerably brighter.

I'd say Mag, too. If you measure the thickness at the center and the edge, you can estimate the curvature (approximating it with an arc), and thus the focal length. This will give you a clue whether a stock Mag head will work, or whether you'll need a deep head, tall bezel, and/or shortened switch tower / deep heat-sink to get the focus right. (You could also double it up, if you've got the one from the other fog lamp...) If it fits in a Mag, and 2D (or 2C) isn't EDCable for you, then look at 1C cutdowns.

BTW, you didn't say... what are you running behind this, LED or hotwire? You can mount an LED substantially further back than the filament on most bulbs, so this is more likely to work out that way in any light.

Cool....I'd like to see if this fits in a mag bezzle.
