Is the Diode Dynamics pair worth the extra money over the Philips?

If you want a documented 5000K white, 3200 lumens per bulb and a ceramic base, yes. If you just need a working OEM-style 4300K replacement, the Philips at $13.99 does that for far less.

Diode Dynamics states 3200 lumens per bulb. Philips does not publish a lumen figure for this bulb, so there is no like-for-like number to compare.

Will either one fit my factory D2R housing?

Both are listed as direct OEM D2R replacements with no modification. Check your owner's manual for D2R before ordering, and confirm the Diode Dynamics listing's size line, which also shows D4S.

Neither listing gives a rated life in hours. Diode Dynamics claims a long, reliable life from its construction but publishes no figure, and Philips publishes none either.

Do I need new ballasts or a wiring harness?

No. Both are bulb-only pairs with no ballast or harness included, and both reuse your existing factory HID ballast and connector.

Is 5000K legal and street-friendly?

Diode Dynamics states DOT/SAE and ECE compliance for arc position and size, and describes 5000K as pure white with no blue tint. The Philips 4300K is the factory-standard color.
