I've resolved to lose weight... well, not my own weight, but the weight of my lights... /ubbthreads/images/graemlins/grin.gif so I need diet suggestions for this 4D Maglite of mine. Note that I DON'T want to change the external 4D housing.
Current configuration: Luxeon V WX1U running on a BB917 converter, 4 D cell body. When loaded with Duracells, the weight of the batteries is 556 grams. (all units in metric because all the datasheets seem to be metric.. sorry guys)
On top of that, I'm suspecting I'm not getting full power from this mod because the BB917 cannot take more than 1.5A of power on the input side. I am suspecting I'm looking at a severe voltage slump on the input because I'm using alkalines. A switch to NiMH seems on the cards. If anybody can confirm/deny the input characteristics of the BB917 that would be very welcome.
These are the ideas I've come up with so far:
1. Re-sleeve the Mag for 4 C cells, 4.8V, 4500mAH, but I'd still be looking at 1.7A on the input. Weight of batteries - 336g, I save 220g.
2. Re-sleeve the Mag for 5 or 6 Sub-C cells, 6 or 7.2V, 3300mAH, for 1.3A and 1.1A input respectively. If I use 5 I'd still have to come up with some kind of dummy spacer. Sub-Cs are a little smaller, so suggestions on what kind of pipe I should be looking for would be great.
The disadvantage of the second idea is that it would take two charge cycles on a 4-channel, 4-bay charger to reload the light (5 or 6 cells, after all).
3. EL's 3toD adapters - somehow I don't seem to want to go this route.
Suggestions welcome.
