This is it in a nut shell There seems to be a real problem with automotive and bike lighting. NO ONE is leading the charge to a better system. DOT seems to be stuck in the 1970's. It took them 20 years to approve the H4 system. DOT is a follower not a leader. Current metrics are dismal at best. Our present low beams only illuminate to 150 feet with the normal 900 lumen halogen bulb, (dual) headlight levels (1800 lumens). 35 mph total stopping distance is 150 feet. 70 mph total stopping distance is 300 feet. In order for us to see twice the distance we will need FOUR times the light! Inverse square law. 50% brighter or twice as bright is NOT enough, we need 400% brighter to see twice as far. So the low beam bulb needs to increase from 900 lumens to 3600 lumens, (or 7,200 lumens total ) for us to be safe at freeway/highway speeds. This is exactly why the new brighter and correctly focused leds bulbs are needed. Now I will argue that 4 times is a minimum and that 10 times brighter is the better number. Our vision is logarithmic so a 10 fold increase is not a big deal. Now the glare issue is made into a stumbling block. The 700 cd number was derived and held over from the incandescent days before the H4 system, projector systems, and better lens/reflector designs. The newer systems with their sharp low beam cutoff can work with much brighter bulbs and still pass the 700 cd glare requirement. The interesting thing is, at the higher light levels on the road you the driver are less affected by on coming glare. With more light you do see better and your eyes respond faster. If everyone increased their low beam light level 10 fold then the 700 cd glare threshold could be increased a little. We are already doing this. Most of you have changed your headlights to brighter LEDs and added aux lighting to your bikes as well. There is a new truck on the road that has 4 low beams and fog lights too. The newer cars and bikes are using brighter leds. It would be nice if there were aux LOW beam led lights (narrow fog with hot spot with a sharp cutoff ) that we could add. How about a LOW beam led light bar...... future cars will not have two low beam headlights but led lights all across the front of the car..... If properly focused and shaped, more light is better. If we can increase the light level to what is needed for the speeds we drive then everyone will benefit. Unfortunately there is still a lot of junk lights out there that is making progress difficult.. ----------------------------------------------------------------------------------------- So how are the newer LED bulbs more focused? You will need to take a closer look at how the LEDs are mounted. The closer they are to the center line of the bulb then you will get a tighter beam pattern. Also the shape of the led also makes a big difference too. The old square and round leds spread out the light in both directions. Where the long thin led will spread the light horizontally and less vertically. This will put more of the light where it needs to be. This is how the Halogen filament is shaped. I cut off the top ends of an older style bulb and a newer bulb so that you can see the difference. The bulb on the left has the square led that is far from the focus point because of the thick heat sink. The one on the right has a thin copper heat sink which gets the back to back LEDs closer to the focus point. This seemingly small change makes a huge improvement in the light pattern, for those of us who like to go fast... OK, What one needs to see is that there are now LED bulbs that have the focus and shape that is very close to the original halogen bulb. This will make the beam pattern and hot spot tighter and gets the light down the road for those of us who ride at the speed limit, The kind of riding where one really needs to see far ahead.... But there are those, who ride in the woods or on tight windy roads. The kind of riding where a highly focused spot would not be as effective. These riders may prefer the previous generation of LED bulbs that do not have a tightly focused pattern. These lights create a much wider and taller beam and do not have the throw that the more focused bulbs have. So there is not one solution but rather many variations that can be tailored to ones riding needs. I have tried to explain the differences so that you will understand what affects the pattern so that you can decide what better fits your needs.
