I will be building a light for family members to take on walks/use around the house. The resident flashoholic will use it as well. I will be using a Malkoff XP-G dropin, with 1,000mA current going to the LED. However, I am undecided as of yet on the cell size and Maglite type. My parameters have been narrowed to one of three cell sizes, and two different Maglite tube lengths. Here are the cell sizes and prices, with accompanying specs:
Option A
Form Factor: Mag 3D
Cell Size: 26650
Capacity: 3,300mAh
Price: $9 * 2 = $18
Pros:
Cons:
Option B
Form Factor: Mag 2D
Cell Size: 32600 (D size)
Capacity: 3,000mAh
Price: $15 * 2 = $30
Pros:
Cons:
Option C
Form Factor: Mag 3D
Cell Size: 32900 (long D size)
Capacity: 4,500mAh
Price: $24 * 2 = $48 :sick2:
Pros:
Cons:
Right now, I am leaning towards the 32600 cell. It is the middle in terms of price, it fits in a compact 2D light (the best light is the one you've got; the light is more likely to be used if it is easy to handle), and it has better specs than the 26650 in terms of discharge.
-------------------------------------------------------------------------------------------------------------------------------------------------------
Bearing the above facts in mind, I have two questions:
1) Subjective
Which of the above LiFePO4 cells and form factors would you choose, and why?
2) Objective
What would the runtime calculations look like for each pair of cells? Gene specs the LED as seeing 1,000mA, so, what would the runtime for each pair be?
I am looking forward to running these comparatively safer LiFe cells in everyone's favorite D size host with one of everyone's favorite dropins.
Thanks!

Option A
Form Factor: Mag 3D
Cell Size: 26650
Capacity: 3,300mAh
Price: $9 * 2 = $18
Pros:
- Cheap
Cons:
- lower capacity
- requires 3D Mag with PVC piping
- longer light
Option B
Form Factor: Mag 2D
Cell Size: 32600 (D size)
Capacity: 3,000mAh
Price: $15 * 2 = $30
Pros:
- Fits a 2D without additional PVC tubing— drops right in
- shorter light
Cons:
- more costly
- lowest capacity
Option C
Form Factor: Mag 3D
Cell Size: 32900 (long D size)
Capacity: 4,500mAh
Price: $24 * 2 = $48 :sick2:
Pros:
- highest capacity
Cons:
- most expensive
- longer light
