Lumens: The better choice for Factory OE replacement HID Parts

At Lumens, we offer high quality replacement Xenon HID parts to replace OE / factory / manufacturers original equipment. These parts are offered in equivalent color replacements (usually 4300K), or various color upgrades. At a fraction of the cost from original equipment offered by the dealerships, and with comparable if not better quality, Lumens offers the best alternatives when replacing or upgrading factory Xenon HID parts.

Currently, the factory Xenon HID market is divided into 4 bulb types (D1, D2, D3, D4) in which they are then divided into 3 other subtypes (S, R, C). The bulb types are not interchangeable. Either the physical connectors are different, or the voltage required is different. D1 and D3 types look physically identical, and D2 and D4 types looks identical. The subtypes differ slightly. S and R bulbs are not interchangeable, but the C (sometimes referred to as 'common') will replace both S and R bulbs. S bulbs are generally found in vehicles with projector housings, while R bulbs are found in the few vehicles with reflector housings. The C type bulbs can physically replace the R type bulbs, but do not have the ceramic sheild to limit the light from the bulb.

	D1 and D3 bulbs: Aside from being just a bulb, these bulbs are easily distinguished by the metal box attached to the actual glass bulb itself. The metal box is an 'igniter' which is generally built as a seperate piece in D2 and D4 systems. These bulb types are much more expensive than its D2 / D4 counterparts for this reason (and also because the other bulb type is more common). There are 2 main differences between D1 and D3 bulbs. First is the voltage required to operate the bulb: D1 bulbs operate at 85V while D3 bulbs operate at 42V. Secondly, D3 bulbs are newer more environmentally friendly versions of D1 bulbs; D3 bulbs are mercury free. Because of these differences, D1 and D3 bulbs cannot be interchanged UNLESS their ballasts are replaced with the corresponding bulbs (you cannot mix components from 2 systems together).
	D2 and D4 bulbs: D2 bulbs are currently the most commonly found HID bulb used by manufacturers. Unlike the D1 and D3 bulbs, these bulbs do not have ignitors built on the bulb itself. The same differences between D1 and D3 bulbs are true for these bulbs. First is the voltage required to operate the bulb: D2 bulbs operate at 85V while D4 bulbs operate at 42V. Secondly, D4 bulbs are newer more environmentally friendly versions of D2 bulbs; D4 bulbs are mercury free.Because of these differences, D2 and D4 bulbs cannot be interchanged UNLESS their ballasts AND IGNITORS are replaced with the corresponding bulbs to create a full D2 OR D4 system (you cannot mix components from 2 systems together).
