Multiple of these in-series circuits are then wired together in parallel to make the complete module. LEDs cause a specific voltage drop, so they are wired in series to reach the target voltage. They have a very specific current breakdown point, so it is common to wire resistors in series with them, to limit the maximum current conducted through the LEDs. LEDs have specific current limitations, and conduct more current as voltage increases. LED MODULE WIRING explanation verified by an Electrical Engineer! They fail the same way Halogens fail (technically halogens are a type of incandescent bulb) Incandescent bulbs last between 100 and 300 hours burn time.The filament degrades with time and with repeated heating and cooling. They fail when the filament breaks from thermal changes.
Halogen bulbs last between 1 hours burn time.They fail when sodium in the burner reacts with aluminum in the arc tube. LEDs last between 10,000 and 50,000 hours burn time.In terms out output, HIDs and LEDs are nearing parity, but the costs associated with each are quite different. HIDs produce 50-150 lm/W, at a low cost per bulb, but a high cost per complete setup. Halogen bulbs can produce 13-24 lm/W at a low cost. Better LEDs produce more lm/W but at a higher cost. Modern LEDs are able to output 40-150 lumens per watt (lm/W). LEDs are much more efficient, at 10-40%, so they should not hit the thermal limit of a housing without grossly exceeding the power spec of the original bulbs. HIDs are a bit more efficient, but still put out considerable heat. Halogens and incandescent are approximately 2.5% efficient, meaning the housings can handle the heat of all but 2.5% of the wattage (since that comes out as light). ***2357 bulbs are brighter, higher-wattage equivalents of 1157 bulbs, so modules intended for 1157 can be substituted if they can achieve at least 500 lm. Price is $150/bulb including shipping.**The VT taillight assemblies use integral LEDs for the taillight. Email us through the contact page, including number of bulbs (1 or 2), your name, address, and phone number, and we will call you regarding payment. Two bulbs installed, with tax: $266.ĭue to overwhelming response LG is now willing to ship bulbs to individuals across the country. The bulbs can be changed from above, without removing anything, in a half hour. We also offer upgraded bulbs that are brighter (Onex Brand D4R 6000K) and whiter in color, upon request. After ardent research we found a direct source for OEM bulbs (Onex Brand D2R for MY 20, Philips Brand D4R 4300K for 2006 and up) for $94 each. Our purpose at Luscious Garage is to fix the problem. Discussion includes class-action plans to speculations of a bad batch around MY 2006. In true form, PriusChat has a hot thread regarding this problem. Warranty coverage varies depending on the service writer on the other side of the counter. The bulbs are thought to last longer (I’ve read up to 8 years), which validates their price, but try explaining that to the owner of a 2006 Prius with no headlights. The Prius is a terrifically economical car, and owners are rightfully shocked by the component failure as well as the cost to repair. Dealer price for one bulb is $314.23 (as of today) and rumor has it that service departments charge an additional couple hundred dollars for the physical replacement, since the procedure calls for removing the whole front clip. In automotive fashion, the improved visibility is of secondary importance to the impression that the car is high tech and sporty-implying the same of the person who drives it.įor Prius owners, when one of these bulbs goes out, the prevailing notion of HIDs is that they are absurdly expensive. Upgraded packages for 2004-2009 Prius include High Intensity Discharge (HID) headlamps that cast a crisper, brighter, cooler-colored light than conventional halogen bulbs.
