These Black Ammo Panoramic LED light bulbs are with bullet-shaped designed shell made of black anodized zinc alloy.  We apply AlphaRex LUXX LED chip on our Black Ammo LED bulb, and each bulb produces output of 60W/5000 lm (raw lumen) and 52W/4250 lm (effective lumen).  With our Panoramic design, the light source comes from the LED chips and emit through the quartz pillar, and generate a 360° light output that adopts the same position as halogen filament to ensure an even beam pattern without dark spot. These Black Ammo Panoramic LED light bulbs work especially well with projector lens and definitely are perfect add-on to your vehicle.
