Generic LED form factor

Does anyone know what is the form factor or name of the original LED?
I found these by the name Luxeon star but I believe that must be the PCB plate?

These are usually found in older crappy flashlights that are rated 1W or 3W.

I want to know the name because I want to buy the appropriate 20mm lens that fits on these.

I just goggle “led bead” and I find ’em.

Grabbed a bunch of WW ones to redo some KL02s or 03s or whatever they are.

Dunno if they have any “name” to ’em.

It’s a Luxeon III clone.

yepp, that’s it. Thanks

I wanted to mod my KL02 clone with a green led. So how did your mod work out?

Didn’t, at least not yet.

Debating whether to just trim down the star (think it’s 18mm to fit), and have a resistor lead tucked underneath and around be the (+) contact, or have a press-fit perfboard under the star for a discrete contact board.

I got as far as trimming a star to fit (WW “bead”, Amazon.com ), measured the crap out of all the internal dimensions and the cell itself (Li cell and 3V converter board, https://www.amazon.com/dp/B0874QQ2C6/ ) so I don’t have to worry about a full 4.2V down to 3.0V supply (ie, cook when fresh, almost nothing when spent).

Soon… I hope.

A CR123 with a built in charger and voltage regulator… Now why didn’t I think of that before? I was concerned about replacing that 1 ohm smd resistor because I may have to use a RC123 at 3.7v.

Glad to help. :laughing:
