Lionheart LED Replacement

If one were to consider replacing the LED in the LH, would he/she replace just the emitter or the entire star?

I would assume it better to replace the whole star so you would not have to worry about centering the emitter yourself?

You would replace the whole star, and it couldn't be much easier. You just need to make two solder connections. /ubbthreads/images/graemlins/smile.gif

What led are you looking for to replace it with?
I liked the slight blueish look on the one idleprocess showed me.

I spoke to Mr Bulk and he recomends a J voltage bin...I was going to swap mine with a TWOJ untill I found out that is what I already have . The VIP looks alot brighter though but I have no way to actualy purchase a better Binned LED since the one that is in there is supposed to be the best of the best already.. Damn you Luxeon Bin Code gods (the creators of all bin codes)!

Ray, if you can solder, you can swap. Replace the entire star, of course. I know you don't care for the blue-white color (my favorite actually) so when you take it off I would gladly swap you for a TWOJ.

If I replace mine with a TWOH would there be any problems? I guess before I do this, can anyone tell if I'd get much improvement in runtime?

The 3.7 volt will somewhat fry the low Vf of the TWO(H) emitter at high power. (H) emitter has the forward turn on voltage starting at 3.03V to 3.27V

It will be brighter, although we all know what happens to "the candle that burns brightest"... /ubbthreads/images/graemlins/mad71.gif

Then again if you think of it as simply a "bulb change" involving a little more hassle (soldering two wires) then...

Also it has been my experience that a slightly lower Vf will not result in catastrophic, dramatic failure. More like a gradual and ever-more-noticeable dimming over time.

So go for it! In fact - I'd like to see how bright a TxxG really could be. /ubbthreads/images/graemlins/naughty.gif

Other than the wires being soldered onto the star is that anything else holding the star in place? Removeal of the bezel cap and reflector clearly expose the star. Is it glued or held in at all?

No, but you need some thermal past for the bottem of the one you are going to install
