The New Hotness

  • Halogen H3 Bulb

    Peering into the bulb salvaged from the Nissan fog light suggests the scuff on the lens corresponds to an impact mighty enough to disarrange the filament:

    Halogen H3 bulb - 1.5 A - light
    Halogen H3 bulb – 1.5 A – light

    No surprise, as the car completely shattered the utility pole.

    The glow draws 1.5 A from a bench supply at 1 V, just to show the filament isn’t lighting up evenly across those gaps. The bulb runs at 55 W from 12 V and would be, I’m sure, blindingly bright, although the heat concentrated in those few coils suggests it’d burn out fairly quickly.

    By LED standards, though, you don’t get much light for your 1.5 W …

    An underexposed version highlights the filament, just for pretty:

    Halogen H3 bulb - 1.5 A - dark
    Halogen H3 bulb – 1.5 A – dark
