So, with this, I hope that I've helped at least one person "see the light!" Ha! Human reaction time is 1.5+ seconds.so you need to see what's 100+ feet ahead, not what's merely 40 feet ahead. What good is seeing the area 0-40 feet ahead of you at 30 MPH? You'll already have covered it in 1 second. I mean, just think about it! 30 MPH is 44 feet/second. And an abundance of foreground light can ultimately glare other drivers. An abundance of foreground light misleads our eyes. Note how none of the OEM or OEM-replica lamps flood the foreground with light-they all keep a cap on how much light is directed 4 degrees below the horizontal-and they all beat the Morimoto Mini H1 7.0 in terms of how much light is projected in the hotspot.įoreground light is comforting, but ultimately useless. If we assume that our headlamps are 36 inches off the ground (basically a F-150 or similar would have lamps that high), then that means our projector retrofit is flooding the area ~0 to 40 feet ahead of the vehicle with light (simple trig with a right triangle, 36 inch height, and 4 degree angle). They're super bright at 4 degrees downward from the height of the lamps. None of this data, as you can see, was pulled out my ass.Īt this point you're probably asking yourself: "well, the projector retrofits look great in pictures, and they are super bright from behind the wheel!" Well, yes, they are, but they're bright in the wrong location. So, without further ado, let's see how a $120 Morimoto Mini H1 7.0 projector stacks up against a bunch of common headlamps, mainly from the last 10-20 years:Īll raw data is available for inspection here. The more luminous intensity recorded at points 11, 12, and 14, the better we can see down the the name of the game, right? This region roughly contains the highest-intensity light in the entire beam pattern.
We'll be looking specifically at points 11, 12, and 14, which form the hotspot. So, how good exactly is a HID projector retrofit?īefore we answer this question, we must first examine this chart.
Led projector retrofit upgrade#
Yeah, there's plug-and-play LED and HID bulbs, but we all know that the ultimate upgrade is the HID projector retrofit, right?
