The hot wire cannot compete in efficiency with the LED, but there is something special and very nostalgic
about that ancient glow...in that light, I intend to own one hotwire build. I will not own or operate a high current light
with LiCo or LiMn cells stacked in series, so that leaves the much kinder LiFePO4 chemsitry.
Perfect, no, but arguably least cruel and by far least likely to "vent with flame".
While many may argue that with proper care, diligent checking with multimeters before, after, and during use, and constant monitoring of cell behavior you can use, at the least, LiMn cells without too much worry, it is not something I want hanging over my head.
Additionally, I already own three LiFePO4 single cell chargers. There is little I need in that department.
That being established, more than three cells in series is just too much for me to keep track of so we are looking at a three cell build, and therefore, a 9.6 pack voltage.
I've studied Lux Luthor's Destructive Tests, without which I would be hopelessly lost, and narrowed down my search to two potential candidates, the GE 347118 35 watt bulb and the JC 5607 20 watt bulb. In their favor, both of these bulbs, through Lux's tests, will not instaflash at initial powerup, and, both of these bulbs appear to be the brightest 6v nominal bulbs when overdriven.
Of the two, I strongly prefer the GE 347118. According to spec, at a 7.3 amp draw, I should easily net over 2,000 bulb lumens. The JC 5607 does "only" about 1,500 lumens. With a near comparable bulb life, I'd rather have the higher current draw and crank out the extra 500 lumens.
This brings me to my questions:
1) Why can't I find any, or rather, hardly any, information on the GE 347118 bulb? A CPF search yields only a couple pages, and Google only takes me back here.
2) Is there an obscure source of GE 347118 bulbs I don't know about? Feel free to email me if you don't want to publicly expose the secret handshake.
3) Lux Luthor points out here that the Osram 64430 has a higher lux at the same drive current, but fewer lumens. I've nearly always cared more about lumens than lux; I want a more floody light. Am I interpreting his post correctly?
4) Finally, is there another 6v bulb that when taken to 9.6v will outperform any of these three bulbs, GE 347118, JC 5607, and Osram 64430?
I feel like there is something I am missing.
