The 2-inch Ultra (BP-106) exists for mounting situations where the 3.0 inch housing physically won't fit — auxiliary bracket mounts on motorcycles, narrow factory fog lamp openings on smaller cars (older Maruti Alto-class, some Tata Punch / Tiago specifications), tight bumper cutouts on retrofits, and any installation constrained by available space. The 2.0 inch lens passes less total light than 3.0 inch, but the Ultra-tier engineering pushes 100W through the smaller aperture — meaning brightness per square centimetre at the lens face is actually higher than the standard Black Phantom variants. It's the right pick when fit takes precedence over absolute light output.

The 3-inch Ultra (BP-105) delivers 110W through a 3.0 inch lens — meaning more total light, a wider perimeter spread, and more thermal mass on the heat sink (which translates to better long-term brightness retention). The 2-inch Ultra (BP-106) delivers 100W through a 2.0 inch lens — meaning a tighter, more concentrated beam pattern and a more compact installation footprint. For factory fog lamp openings that fit 3.0 inch, choose the 3-inch; for everywhere the 3-inch doesn't fit, the 2-inch is the right answer. ₹5,000 separates them (₹11,995 vs ₹16,995) because the 2-inch uses less material and a smaller heat sink.

Yes — the 2.0 inch housing is sized for motorcycle auxiliary lamp brackets typical on Royal Enfield Himalayan, KTM 390 Adventure, BMW G310 GS, and similar adventure motorcycles. Voltage range (9-16V) matches motorcycle electrical systems. Use the supplied wiring kit and add a relay (some motorcycles can run aux lamps directly off the headlight high-beam, but for sustained 100W draw a relay is safer). Mounting will depend on your bike — most aux-lamp brackets are sized for either 2.0 inch or 3.0 inch housings, with 2.0 inch being more common on modern adventure bikes.

Total light output is roughly proportional to power, so the 2-inch at 100W vs the 3-inch at 110W differ by about 10% in total lumens — close but not identical. The lens size changes the beam character: the smaller 2.0 inch aperture produces a tighter, more focused hotspot with a narrower perimeter spread. For a long, straight road, the 2-inch reach is actually competitive. For a winding road where you need to see the edges, the 3-inch is the better tool because its wider perimeter spread illuminates more peripheral road area. Most owners pick by mounting fit first, then accept the beam character that comes with the size.

100W per lamp (200W per pair on a car, or 100W for a single bike aux) is well within automotive electrical capacity but worth wiring through a relay. The supplied wiring kit supports this. On motorcycles, also check that your stator output can sustain the additional load — most modern adventure motorcycles have 300W+ alternators which handle aux lamps comfortably, but older or smaller bikes (<250cc) may need an upgraded stator if you're running multiple aux electrical accessories.

Even though the 2-inch is the most compact Black Phantom, the installation still involves high-current wiring through a relay, properly aiming the beam, and (for the 3 Colour) mounting the colour-toggle switch within driver/rider reach. On cars, an automotive electrician completes this in 2 hours. On motorcycles, a qualified bike electrician handles it similarly. Mistakes — wrong wire gauge, ungrounded relay, mis-aimed beam — are the same regardless of lamp size.

3000K yellow is for low-visibility weather: dense fog (especially Punjab winter fog, Western Ghats monsoon, Himalayan whiteouts), heavy rain, dust storms, snow. Water droplets and dust particles reflect cool white light back at you, creating a wall of glare. Yellow wavelengths pass through with less scattering. On a motorcycle this matters more than on a car — a rider's eyes are further forward and less shielded, so back-scattered glare from cool white in fog or rain is much more disruptive. Switch to 3000K the moment visibility drops to under 100m.

IP67 means the housing is sealed against dust ingress and withstands temporary submersion in water up to 1 metre for 30 minutes. Normal rain, monsoon spray, car washes, motorcycle wash-downs, and even occasional river-crossings are fine. Direct high-pressure jet washing on the lens or seal area is not recommended — it can force water past seals that are designed for static immersion, not pressurised spray.
