9005 Bulb (HB3) vs. D2S / D2R HID Xenon
Comparing 2 standards across 10 specifications. 10 key differences identified.
The 9005 Bulb (designated as HB3 under ECE Regulation 37 with a P20d right-angle base) is the high-output single-filament halogen standard designed specifically for dedicated automotive high-beam headlights. Operating at 65W nominal at 12V, generating a powerful 1,700 lumens with an unpainted clear quartz bulb tip for maximum forward optical throw.
D2S and D2R Bulbs (standardized under UN ECE Regulation 99 with a P32d base) are High-Intensity Discharge (HID) automotive lamps that produce light by igniting an electric plasma arc inside a quartz glass chamber filled with Xenon gas and metal-halide salts. Operating at 35W nominal and generating an intense 3,200 lumens (~2.1× the brightness of halogen).

|
Base Socket Designation
|
P20d (90° right-angle molded plastic base with 3-tab bayonet twist lock) | P32d-2 (D2S for projector lenses) | P32d-3 (D2R with black ceramic mask for reflector optics) |
|
Luminous Flux Output
|
1,700 lumens ± 12% (high photometric output for long-distance night penetration) | 3,200 lumens ± 15% (Color Temperature: 4150 K to 4300 K standard OEM daylight) |

Nominal Power & Voltage
|
65 W @ 12V (tested at 13.2V; draws ~4.92 A) | — |
|
Quartz Bulb Tip
|
Clear glass tip (no black top coating; allows 100% of forward light to escape into high-beam reflectors) | — |
|
Low-Beam Sibling (9006 / HB4)
|
9006 / HB4 is the 55W / 1,000 lm low-beam counterpart (P22d base with a black-coated top tip) | — |
|
Arc Chamber Chemistry
|
— | Xenon gas (provides instant initial glow) + Mercury + Metal-Halide salts (ScI₃ / NaI create daylight white plasma arc) |
