I want to put a new L Star in my Zenix IQ - help!

tysonb · Aug 1, 2005

Hello,

i just purchased a new Zenix IQ and would like to upgrade the LStar that it came with - QX1JW. Anyone have any ideas on how to make this brighter and whiter?

Should I just pop in a Lux3 and run it underdriven? I am pretty much only intereseted in a straight star swap as my soldering skills are not quite where my courage needs them to be.

Thanks,

Tysonb

R bin star is the brightest Lux I available. Consider WO or XO for a whiter beam. My personnal favorite is XO tint.

Just took mine apart I got at QYAJ, I see the Shoppe has some RYOJ's for 17 bucks. I have a few TWOJ LuxIII stars now which would be the better swap /ubbthreads/images/graemlins/confused.gif

Under driving a TWOJ will give you an ugly yellow/greenish tint. Check the driving current first. If it is under 400mA, I would go for a Lux I because the brightness between Lux I and Lux III is barely noticeable under such low current.

I put a twoh in my arc ls

at stock current it is very white

it stays white even as the battery dies.

can I check the current across the leads with the star connected, or do I need to take it apart first?

I did the swap and put the TWOJ in you have to trim the plastic ridges down right behind the star a little because the LuxIII is a little thicker than the LuxI other than that it's a drop in mod.

It looks a little brighter to the eye and the color is much whiter on all levels than the QYAJ. I may swap it back out tonight after work and check it with a light meter and compare the two so far I like it /ubbthreads/images/graemlins/grin.gif

Tyson,

I did the swap again to check them with a light meter and got 460 Lux with the QYAJ LuxI and 631 Lux with the TWOJ LuxIII YMMV from star to star but that 171 Lux difference at 1 meter. Another thing I noticed right off going from the low dome to a high dome is the beam is much smoother, has better spill and the ring around the outside of the beam is gone.

tyson,
You can measure voltage at the LED without removing the LED, but to measure current you need to insert the voltmeter (set to measure current, of course) in series with the LED, so you need to unsolder at least one of the terminals (pos or neg, it does not mater which one).

Thanks for all of the help. I have a 3 watter on order and will soon make the swap.
