Best Battery Choice for T Binned LuxV?

[Habuteru]

Hi all,

I am attempting my first mod, a Space Needle type light using an OAD O-sink, a borofloat lens and a T binned LuxV. I also purchased a FatMan regulator board and plan on driving the LuxV at 1A.

The only thing I need to do now is figure out what D cell mag body and batteries to use.

If I understand Georges80, the FatMan will regulate as long as the Vin does not exceed the Vf of the LuxV. Correct? So as long as I don't exceed ~6.5V the FatMan will work as intended, anything over that will be direct drive. Am I then free to choose the highest mAh I can find as long as I don't exceed a Vf of 6.5?

I was thinking about either 4 NiMH D cells in a 4D Mag body, or 4 NiMH C cells in a 3D body. Is there a better choice that I am missing? Should I buy a different regulator to use in this mod?

Thanks in advance, comments and suggestions are greatly appreciated!

This link (which you might have seen) has the voltages for each bin:

This other link has lots of good info. Note the first column on the left which shows the unloaded voltage - that should give you an idea of several possible configurations: Direct Drive Chart ...

Good luck /ubbthreads/images/graemlins/smile.gif

I built my Lux V Mag mod using a 4 D body light with a boost converter. It works nicely, but it's really long. I find myself not using it as much as I would if it were smaller/shorter and more manageable.

If/when I do it again, I'm going to consider one of two other options. I want to stay with regulation, so my first choice might be going with some 3 or 4 AA to D adapters in a 2 D body with a buck converter. My other choice could be just sleeving a 3 C body for 123s and using a buck converter. At this point, I'm leaning toward using the 3 C body and sleeving it because battery changes would be easier in the field.

Using is a boost converter is not the only way to go with a Lux V.
