Does anyone know the current draw of

"LMXA601"

by Maglite?

Tailcap measurements off 2x18650 or 6C/6D cells would be greatly appreciated.

Since regulated incandescent drivers are not currently available, I was wondering if this would be a nice upgrade with relatively flat/white output off 2x18650, 2x26650, or 2x32650.

However, I don't know how to compute runtime without knowing the current draw.

There are lots of esoteric bulbs out there; I would rather go with something commonly available and cheap. Plentiful and frugal wins the day for me over $15.00 (or more) boutique bulbs.

Thanks for the ping back.

The original 6C/6D "Magnum Star" xenon bulb is documented as drawing 850mA off two 18650 cells.

I am curious as to whether the second generation xenon bi-pin bulb also draws 850mA for the additional 12 lumens.

If anyone has the facility to post beamshots of the first and second generation 6C/6D xenon bulbs side by side, i.e., the "Magnum Star" and "Magnum Star II" bulbs, that would rock. *thumbs up*

This is pure speculation, but, I wonder who the OEM is...made in Germany...hmm...Philips...?

Similar question was answered here.
For higher output from your 2x18650, 2x26650, or 2x32650 system, you may try TL-3 bulb which has slightly different spacing of pins. Your next even higher choice is 1499 and ultimate brightness choice is 1794.

Thank you, fivemega. Since all the new bi-pin bulbs are automatically the Magnum Star II xenon bulbs, the current draw of 900mA is the answer to my question.

Also:

@fivemega, email sent!

I do have a single Magnum Star I PR bulb left and many bi-pin II bulbs and access to a lightmeter, however, 12 lumens may fall within the range of differences due to cells and host resistance.

Bonus Points:

Can anyone tell me the current draw for the four cell versions of the second generation, bi-pin, Magnum Star II xenon bulbs?

The product code for the four cell version is LMXA401 and it is rated at 104 lumens.
