[QUOTE="jarance, post: 448663, member: 21"] both of them give the same white light. CCFL - cold cathode fluorescent light - Use an inverter to convert 12VDC to high frequency and high voltage to light up up a fluorescent tube. SMD-LED - Surface mounted device - Light emitting diodes - An array of LED (High intensity cluster together) to give white light. Sub miniature resistors are incorporated to work at 12VDC. So basically plug and play. [B][U] Pro & Cons[/U][/B] CCFL - Cons - Need inverter to work. Have to install outside the headlamp and have tendency to short circuit when exposed to rain. Some people install inside headlamp but will faced problem due to over heating from the headlamp. SMD-LED - Just plug and play. Presently still expensive cos relative new in market. Expect the price to drop once supplier bring it in. (same like CCFL when it was first available). Some LEDs may blow due to mishandling.
