![]() The flattest, most even pattern in HID came from the Range Rover. The hotspots from the Highlander headlights with HID bulbs were middle of the road comparable to Lexus, BMW, and Mazda. IMO, hotspots are bad as they create strain on the eye with too much contrast on the other parts of the road you're supposed to pay attention to. In fact, some of the factory cars had hotter spots in the foreground. Comparing the beam pattern of the HID in our headlights to those of Lexus, BMW, Range Rover, Mazda, Audi, and Infiniti I felt the hotspots weren't a big deal. I had several factory equipped HID cars pull up along side me on the highway at night, and I passed a few others. I just wanted to update after driving around with the HID 4300K Philips. Hotspots concentrated in parallel with projectorĨ:30PM, 55F, dry roads, 3-4 lane highways.Closest of the 3 aftermarket bulbs to keeping stock beam pattern.This likely is the reason glare is kept to a minimum compared to the HID bulbs. No crest at the top of the beam (parallel/inline to the projector) due to diodes only being on left and right of the LED bulb.Better distance than Halogen, but not as good as HID.Barely noticed the beam pattern compared to no headlights on in the parking garage.In actuality, my headlights are adjusted so that my cutoff is just at the top of the license plates on the cars. That dark spot is the crest of the "hill", and this results in the cutoff appearing to be higher than it should be on the far wall. If you look at the middle of the parking lot you'll see a black line going across left to right. It slopes up about 50 yards and then begins to slope back down. Note that in this shot the ground is not even. I went out and found the darkest garage I could find to get dry photos of the beam pattern, cutoff, spread, and any scatter. White Balance 3800K for wall shot, and 3800K for distance shot.Well, dry photos happened when I located a nice, empty parking garage.ĩPM, 38F, Parking Garage with scattered overhead lights ![]() Will color shift to approximately 4700K.Definitely brighter than Halogen, and slightly brighter than LED.Must warm up to reach peak light output.Operating temperate at the arc was 300-400 degrees F.More stuff to install means more places you need to mount your hardware.Instant on with peak light output (really cool, and really nice).Operate at about 100 degrees F +/- 20 degrees at the base AND diode regions.The fewer parts to this upgrade make it nice. Super easy to tuck away and cleanly install.Operate at about 300 degrees F +/- 60 degrees.Still, the LED bulb in dry conditions actually throws very even light that is whiter and brighter than the halogens (been running them for a month now). Here you can see how similar the beam pattern is at close range between the bulbs, save for the one that looks like a butterfly (H11 LED). Hotspots cannot be fully assessed due to the rain and wet ground, so I would like to take more photos on a dry night to further compare. Wth first hand experience from this shoot I can tell you that the glare was "perceived" the same from my eyes and my neighbors between all the bulbs. Getting a good head-on photo to depict any glare was fruitless, since the dynamic range of a camera doesn't make for an accurate assessment with how intense all the bulbs appear to the camera sensor. The "glare streak" on the right garage door is due to the puddle on the right side of the alley, and it exists in all photos (albeit not so prominent with the Halogen). ![]() Either way, the consistent camera settings make for as best a comparison as possible. This was to ensure we'd get a proper color comparison between each light source, and it created a photo as close to what I saw in real life. White balance was established using a gray card in ambient light. ![]() (1) Garage (shots of driver's side only, as beam is mirrored exactly left or right) No H9 bulb, because I didn't want to pay $30 bucks for bulbs that I have to modify and know I will never use.Ĭonditions of this shoot and camera settings: XenonDepot HID Philips 5000K Xtreme kit. ![]()
