Which is brighter, the OSRAM or the Morimoto?

The Morimoto XB is rated about 3400 lumens versus 2800 for the OSRAM Xenarc Original. The gap is modest and mostly noticeable on dark roads.

Morimoto rates the XB at 2500 hours and backs it with a 2-year warranty. OSRAM does not publish a life figure for the Xenarc Original, so the Morimoto is the safer bet on paper.

Is the Morimoto worth the extra cost?

At $39.99 for a pair versus $21.55 for one OSRAM bulb, the Morimoto gives you two bulbs, more output and a warranty for about the same money per bulb. It is worth it if you want a whiter beam.

Will the 5000K Morimoto match my factory lights?

No. Factory HID is usually around 4100-4300K, so the 5000K Morimoto will look whiter and slightly cooler. The OSRAM at 4150K matches the stock color.

Do both fit the same socket?

Yes. Both are D2R bulbs with a P32d3 base, so they fit the same housing. The Morimoto also works with 55W ballasts; the OSRAM is 35W only.

Should I replace both sides at once?

Yes. HID bulbs shift color as they age, so a new bulb next to an old one can look mismatched. The Morimoto pair covers both sides in one purchase.

OSRAM Xenarc Original D2R 35W HID Bulb vs D2R XB 5000K HID Bulbs (Pair)

Buy the OSRAM Xenarc Original if you want the stock look and the lowest cost: $21.55 at eBay as of November 5, 2026, versus $39.99 at Amazon for the Morimoto pair. Buy the Morimoto XB pair if you want a whiter 5000K beam, a two-year warranty and two bulbs for the price. The OSRAM is one bulb at roughly half the price per bulb, so the Morimoto pair is the better value only if you need both sides or prefer the cooler color.
