People are also getting a mixed bag on quality as shown in the video. Each bulb has a different measurement and design with no set standard, unlike the halogen.\r\n\r\nLED bulbs are a completely different technology when compared to halogen bulbs. They do both emit light, but the way that they do it are different.\r\n\r\nAn LED bulb produces light by passing the electric current through a semiconducting material—the diode—which then emits photons (light) through the principle of electroluminescence.\r\n\r\nHalogen bulbs work just like with incandescent light bulbs, the electrical current enters the socket and travels up to the tungsten filament, heating up the filament to incandescence. The enhancement with halogen lamps is that the filament is enclosed in a quartz capsule filled with halogen gas.\r\n\r\n[LED Lightbulb](https://i.imgur.com/CfGOmFJ.jpg)\r\n\r\n[Halogen Lightbulb](https://i.imgur.com/VdgBQoy.jpg)\r\n\r\nIf we compare the two bulbs above, we can notice how the LED tries to mimic the halogen as best as it can. However, there is one big flaw, the LEDs can only emit light in one direction, that is perpendicular to the surface that it is mounted on. There is also a large heatsink to draw away the heat that the LEDs emit. On the other hand, the halogen can emit light from all direction (omnidirectional) and does not require a heatsink.\r\n\r\nHow does this affect light output? [Here](https://i.imgur.com/703dhpV.jpg) is an LED bulb when it is turned on. The large heatsink and the way the LEDs work, create a massive dark area that light would never reach. This is critical in a headlight as they are [designed to focus](https://i.imgur.com/iEc3fCl.jpg) light in certain areas and at certain intensity. Just slightly altering the angle at which light comes out of the headlight can translate to a few feet of light being casted somewhere where it is useless to a driver. The same thing happens in a projector housings as well. [The focal point at where the light is focused inside a projector is moved.](https://i.imgur.com/wROvrnX.jpg) Very similar to how our eyeballs work and how people can have [nearsightedness or farsightedness.](https://i.imgur.com/FUGF89l.jpg)\r\n\r\n[Here is how an LED looks like in a reflector headlight.](https://i.imgur.com/za7S8RL.jpg)\r\n\r\nIn the end, there's nothing that you can do to try and fix the light output of the LED bulb, because physically, they are completely different. The diodes of the LED will always be out of focus when installed into a halogen housing. \r\n\r\nReference:\r\n\r\n[Evaluation of After-Market Light Emitting Diode Headlight Bulbs\r\n](https://saemobilus.sae.org/content/2019-01-0850/)     \r\n\r\n[Thinking of converting your halogen headlamps to HID or LED?](http://www.danielsternlighting.com/tech/bulbs/Hid/conversions/conversions.html)\r\n\r\nI recommend installing high quality halogen bulbs.\r\n\r\n**H11 Bulbs (Low Beam)**         \r\n[Philips H11 NightGuide Platinum](https://smile.amazon.com/dp/B099G5Z1GY/ref=cm_sw_r_awdo_navT_g_BRR8FFKKZY3FZAMB4Z19?psc=1)    \r\n[OSRAM NIGHT BREAKER LASER H11\r\n](https://smile.amazon.com/dp/B07FXRDJW2/ref=cm_sw_r_cp_apa_fabc_VOmdGbAJ20X3G)    \r\n[SYLVANIA H11 SilverStar Ultra](https://smile.amazon.com/dp/B008BE04C6/ref=cm_sw_r_apan_glt_i_Y2Q25DY95HZM8PW0KPRE)    \r\n[GE Lighting H11 Nighthawk Xenon](https://smile.amazon.com/dp/B00GZHC2L2/ref=cm_sw_r_apan_glt_i_HDBH5HN7QHVTG81GF7H5)\r\n\r\n**9005 Bulbs (High Beam)**   \r\n[Philips 9005 NightGuide Platinum](https://smile.amazon.com/dp/B099GHXVZ5/ref=cm_sw_r_apan_glt_fabc_85T4EVM9S9PCT4S9CMSP)     \r\n[OSRAM NIGHT BREAKER LASER HB3/9005](https://smile.amazon.com/dp/B07FY4WS8J/ref=cm_sw_r_cp_apa_fabc_w7mdGbJXQ007N)     \r\n[SYLVANIA 9005 SilverStar Ultra](https://smile.amazon.com/dp/B000M5W25E/ref=cm_sw_r_apan_glt_i_QHRSR1JZ8WBMEXSHS9F5)    \r\n[GE Lighting 9005 Nighthawk Xenon](https://smile.amazon.com/dp/B00GZHC0G4/ref=cm_sw_r_awdo_H4J6BRBDTEMX0FDYKQXH)","subreddit_name":"Honda","author":"tofu2012"},{"body":"LED headlight bulbs, _especially_ in reflectors, are not upgrades.

People would be more inclined to buy directly from a dealership instead of buying LED bulbs online from companies that they have never heard of before. Sales people could easily up-sell LED bulbs if the same claims that online sellers make are true.\r\n\r\nInstead, car manufacturers spend time and money creating new headlamps specifically for LED technology. They even go as far as over designing these headlamps to get a perfect score from [IIHS](https://www.iihs.org/ratings/about-our-tests#headlight-evaluation).\r\n\r\nI recommend installing high quality halogen bulbs.\r\n\r\n**H11 Bulbs (Low Beam)**         \r\n[Philips H11 NightGuide Platinum](https://smile.amazon.com/dp/B099G5Z1GY/ref=cm_sw_r_awdo_navT_g_BRR8FFKKZY3FZAMB4Z19?psc=1)    \r\n[OSRAM NIGHT BREAKER LASER H11\r\n](https://smile.amazon.com/dp/B07FXRDJW2/ref=cm_sw_r_cp_apa_fabc_VOmdGbAJ20X3G)    \r\n[SYLVANIA H11 SilverStar Ultra](https://smile.amazon.com/dp/B008BE04C6/ref=cm_sw_r_apan_glt_i_Y2Q25DY95HZM8PW0KPRE)    \r\n[GE Lighting H11 Nighthawk Xenon](https://smile.amazon.com/dp/B00GZHC2L2/ref=cm_sw_r_apan_glt_i_HDBH5HN7QHVTG81GF7H5)\r\n\r\n**9005 Bulbs (High Beam)**   \r\n[Philips 9005 NightGuide Platinum](https://smile.amazon.com/dp/B099GHXVZ5/ref=cm_sw_r_apan_glt_fabc_85T4EVM9S9PCT4S9CMSP)     \r\n[OSRAM NIGHT BREAKER LASER HB3/9005](https://smile.amazon.com/dp/B07FY4WS8J/ref=cm_sw_r_cp_apa_fabc_w7mdGbJXQ007N)     \r\n[SYLVANIA 9005 SilverStar Ultra](https://smile.amazon.com/dp/B000M5W25E/ref=cm_sw_r_apan_glt_i_QHRSR1JZ8WBMEXSHS9F5)    \r\n[GE Lighting 9005 Nighthawk Xenon](https://smile.amazon.com/dp/B00GZHC0G4/ref=cm_sw_r_awdo_H4J6BRBDTEMX0FDYKQXH)","subreddit_name":"civic","author":"tofu2012"},{"body":"LED headlight bulbs, _especially_ in reflectors, are not upgrades.

You can get close to a white halogen, but you will never get something like 4000 kelvins. This is due to the technology of the bulb.\r\n\r\nSome halogen bulbs claim to be true white by coating the entire bulb in blue tint. This actually reduces the performance of the bulb as the yellow light wavelength is filtered out, effectively reducing the amount of light being thrown out. Ingeniously, manufacturers have figured out that they can coat certain areas of the bulb in blue tint to give off a white light, but still output its full performance.
