Review on 🔦 Cougar Motor 9006 LED Bulbs, K16 Series HB4 All-in-One Conversion Kit - 10000 Lumens, 6000K Cool White, Quick Installation Halogen Replacement by Justin Woolley

These bulbs replace some of the cheap xenon bulbs I bought online from an unbranded Chinese manufacturer about a year ago. I replaced the old headlight housing with a new one along with these bulbs. The difference in brightness before and after amazed me, but the impression of the object is subject to emotions, so I measured the output brightness using a Samsung phone and the Lux Light Meter app. Due to space and weather conditions, test measurements were taken at a distance of 1 meter (3.82 feet) from the lenses. This should be measured at a distance of 25 feet from a white wall or similar white surface. 55W ballasts with independent relays for the right and left headlights were used. Here are the readings: D2S bulb (5000K) in a new fixture - 18,252 lux D2S bulb (5,000K) in an old fixture - 14,001 lux Cheap bulb (6000K) in an old fixture - 6,679 lux. Some considerations should be made here should be mentioned: The old headlight had a reflective chrome finish. (elliptical body) is opaque and the inside of the headlamp cover was slightly yellowed, usually due to the sun's UV rays and xenon lamps. Earlier cheap incandescent bulbs were rated at 6000K and used 35W Hella ballasts. The new lamps are powered by 55W digital ballasts (similar to those from Innovated). The difference in light output is significant. Also note that a 55w ballast lowers the Kelvin so 6000K drops to 5000K making it whiter and you can measure this with an app or photometer. I will be installing 35w ballasts to extend the life of these bulbs, update the base ratings and get true 5000k light. Final recommendation, if using aftermarket ballasts use the correct relays with the correct fuse rating (20A per side or 30-40 if common). ), saving on wiring your lighting system and extending the life of your lamps. On another car, the aftermarket kit lasted 13 years with no problems with the relay.
