Marcad,
You may have coincidently found an LED bulb which pairs well with a halogen projector and produces a decent light output but the reality is LED bulbs can't offer the same beam pattern as halogens in a halogen projector. The optics are specifically designed for a single light source (as opposed to 2 pointing opposing directions with likely around a 120 degree beam pattern).
The wall shots you posted are way to close to really tell anything, many headlight projectors need some distance to full develop their beam pattern. If you can find a large white wall and park ~25ft away with the headlights projecting onto the wall, this will be much more telling of what the real world output is like.
It is common for people to perceive light as being brighter with these plug-and-play LED bulbs but that is usually to A) the whiter kelvin rating and B) the poorly formed beam pattern from the LED bulbs can lead to a very strong foreground, the light immediately on the ground in front of the car. The bright foreground can actually be counterproductive as it will make your eyes constrict and make it harder to see distant light. Just like big engines (or electric motors) and poor tires; power is nothing without control.
The best solution for improving road-legal headlight performance is a proper HID projector retrofit, period. Understanding people may want to optimize the output with their current halogen projectors, installing a quality/reputable HID kit can offer improved intensity but just like with the LED bulbs, halogen projector optics are not designed for HID bulbs. That being said sometimes you can get decent results, some halogen projectors will offer a decent output which is a legitimate upgrade over stock halogen, however sometimes the HID bulb/halogen projector combo can yield output which bleeds above the cutoff line, creating dangerous glare for coming traffic. By the way, stay away from Amazon, eBay, etc. you usually get what you pay for or get a knock-off.
What I would recommend for Tesla owners with halogen headlights who want a bump in performance; get a set of HIR halogen bulbs. IIRC correctly the Model S has a 9005 bulb, so a 9011/9012 bulb can fit with some minor modification, see this link:
HIR bulb base modification
HIR bulbs has an infrared coating on the glass which reflects heat/energy back into the tungsten, essentially amplifying the output. The end result is a halogen bulb which draws the same amount of energy as stock but produces about 80% more light. Perfect optics and beam pattern are retained and a pair of HIR bulbs will only run about $40/pr for pair of Philips bulbs.
For reference this is a rough breakdown on how the the outputs should stack up:
Stock 9005 Halogen 55w: 1,000 lumens
9011 HIR Halogen 55w: 1,850 lumens
Quality 35w HID Kit: 2,800 lumens
* Keep in mind that added output of the HID kit won't necessarily be utilized properly since it is being projected out of a non-HID projector. Many of the cheap Amazon and eBay HID kits will be putting out more like 2,000 lumens due to the poor quality bulbs and ballasts.
Someone who owns halogen headlights should do a side-side comparison with a HIR bulb and HID kit, or send me a halogen headlight, I would be happy to whip up a test for the community.
