Q. Which is better: led or halogen bike headlights?

Answer

LED headlights cost at least 5–10 times as much as their halogen counterparts, but they have a luminous efficiency of 40–50 percent, can last up to 20,000 hours (nearly 20 times as long), and are environmentally friendly. Additionally, LED lights are larger in size than halogen bulbs. Therefore, homes may save money on their power bills by making the conversion from halogen to LED lighting. However, LEDs do more than only reduce energy usage. At least 80% of modern automobiles include halogen headlights, as these are the most popular option. LED headlights are now also available as an option for buyers.
