ZEK Super Bright LED Headlight Bulbs - Adjustable Focus Length Conversion Kit - H11 (H8 , H9) - 110w 10,400Lm 6000K Cool White - 2 Yr Warranty (H11, H8, H9 (55W))

Built nice, appears robust, application was a different story. Thank God they are adjustable or they flat out wouldn't have worked in my right highbeam reflectors as the leds would not go horizontal (3 o'clock & 9 o'clock.)The fans are quiet and drivers are robust.I managed to strip one set screw but two extra screws are provided and another set hole is provided at 180 degrees.They cast a goodly amount of light but everywhere except where I wanted "in the distance".Very bright in front of my car but my lowbeams and fog lights already do that.I measured them in my H9 application against my stock bulbs and the led is the exact same distance as my stock filament so I didn't attempt to adjust the length.I really think the non-omnidirectional throw is some of the problem. They may also be tilted different than stock.All in all, lots of light but not where I need.I'm returning them and will try omnidirectional type next.Btw, I bought two pair with one intended for my lowbeams but there wasn't enough clearance as the fan was about 1/8" too long.

I don't really "dislike" these bulbs, because they are bright....brighter than my 6000K LEDs that I had installed prior. But these are more on the "white light" side, aka "5000K". Not the "6000K" color that's advertised. 6000K bulbs should have a slight bluish hue to them, as you can see in the pics. To be more specific, in the pics, I only installed the ZEK LED bulb on the driver's side(right side headlight when you're looking at the pic). You can clearly see that the ZEK bulb is brighter than the left side(passenger side). Please note that prior, I had the SAME 6000K LEDs from the different brand installed in the fog lights as well. In conclusion......If you are looking for a brighter, more efficient, and longer lasting alternative to Halogen bulbs....while at the same time, being a longer lasting alternative to HID bulbs, these will certainly do the job.

Wanted more lumens then the LED lamps i was using(about 7600). These claim 10,400/pair and i believe they are. They give me more light to the sides and forward. They don't shine further down the road then the previous LED but objects(signs,parked cars etc.) are illuminated much better. Only gave 4 stars because the fans are louder then my previous lamps.

BRIGHT WHITE WIDE PERFECT BEAM PATTERN NO DARK SPOTS

These work great and I would recommend these as replacement of HID conversions
