Low beam patten shows some differences from old bulb which was a Sealight Laxmas L1 with similar specs but much lower real performance though the pattern the produced was almost exact duplicate of the original halogen bulb pattern. Main difference with these is the hot spot had a very clearly defined block shaped hot spot emanating from the side of the bulb that produces the deer finder beam that shoots up to the right to help in reading signs. This clearly does not affect the performance of this bulb on low beam & may in fact help it.
High beam is also very bright, maybe even too bright as much of that light is scattered in a way that the up close light is no dimmer on high beam than on low beam. This produces a situation where the pupils of the eyes are shutting down when they should be opening to be able to see dimly lit stuff in the distance more clearly. Everything up close is very brightly lit, both the trees & the road surface, in fact the up close road surface is as brightly lit as it was on low beam. Projection though looks about the same though as my previous much dimmer bulbs.
I do love these bulbs though & I like the the regulator I separate from the bulb package meaning the regulator isn't adding heat to an already stressed heating as it was on my previous bulbs. This allows the heat sink for the bulb to be able to absorb more heat from bulb itself allowing it to be brighter.
I didn't make any pictures myself. Someone else posted a picture showing the block shaped hotspot & most pictures do not accurately reflect the color temerature or brightness of headlight bulbs. Nor do videos.
As far as longevity these are new to me & may post an update later.
The instal for most people will be quite easy. In my case I had to remove headlight housings on my 2006 Toyota Prius which meant also dropping the bumper cover some. Other than that & dealing with the after affects of a stroke I had a couple years ago the rest of the instal was easy.
Update, I raised the beams slightly about an inch at 10@ feet & this did provide some improvement to distance on high beam. It did not cause any problems with glare for other drivers as beam on low beam was still lower than the lowest rear windows & people approaching you head on were in a space that hot part of the low beam didn't extend out toward them until they were within 15-20 feet in front of me & even then it would just be hitting near bottom of tires. No one flashed me.
Concerning brightness. These remind me on high beam of the setup I had in my 2014 Dodge Avenger which had Morimoto HID low beams & Vled high beams combined when on high beam. This to me was the cats meow but these pretty much match my old Avengers setup for brightness & distance on high beam & it does it with just one bulb per side. This is incredible.
Edit. Did some experiments & comparisons to my old laxmas L1. The Laxmas L1 light chips were protruding further into the housing than the X2. This was causing a slight misfocus of the X2 causing dearfinder to be thicker than it should on low beam. It was also causing the high beam to scatter & have an ill defined center.
I pulled the bulb out & removed the rubber o-ring gasket & used silcon rubber cement to reinstall. This slight difference in placement of the chips within the housing completely solved issues with both beams.
The less protrusion into the housing of the stock X2 appears to be compensation for the thickness of the body where the chips are mounted to try to get same focus as halogen bulb. They just ever so slightly overshot the target to get perfect focus. A small difference is still there as far as protrusion into housing but the thickness of heatsink is perfectly compensated for by allowing the bulb to protrude into housing the full depth allowed by removing the o-ring gasket.
I tested the modification as described above by driving out a known road that is perfect for testing lights & the results are great. It worked as expected. Beam scatter is not an issue now & high beam projects further down the road. Verticle spred of light is vastly reduced putting more light where it is needed & less where it is not. High beam hot spot is now very clearly defined & properly placed. Light on road near car is now reduced significantly though still pretty strong due to the intense brightness of the bulb.
Low beam still very smooth, in fact smoother & transition to the deer finder part of beam is as good as it is with stock halogen. Just one he'll of a lot brighter when it comes to lighting the road. There is no more block of bright light coming from deer finder part of the beam, also no fuzzy cutoff point that you see in other pictures here on site when you compare it to stock or some other high qualty LED lights by same company. The character of the light on either beam where it hits the pavement is an almost pure white sheet with only the very slightest hint of yellow suggesting color temperature to be at or slightly below 6000 kelvin.
I seriously love these headlights, even better now that minor issue is fixed though given the brightness of these bulbs it is not really a minor issue to oncoming drivers so glad it is fixed. It is only minor in that the fix was so easy. Most anyone can do it.
I decided to add some pictures showing the improved low beam cut off & lack of large block of bright light from the deer finder part of the beam. Note the extremely smooth transition from the cutoff on left side of beam to right-side of beam where the deer finder part of beam is. Also the sharpness of the cutoff is vastly superior compared to the bulb as delivered.
