You can find them in stadiums, warehouses, and of course, on automotive headlamps. In automotive applications, the total brightness can vary widely based on the quality of the components, operating temperature, condition of the bulb, and other factors.
Brightness of light for HIDs is usually measured in lumens, or the total amount of light generated. Lumens are the unit of luminous flux, which is the total power of light. To measure lumens, an HID bulb is placed inside a sealed reflective sphere, known as an integrating sphere, and its light is bounced around in all directions in the sphere integrated so its power of light can be measured at one point, and then calculated into lumens based on the size of the sphere.
The light source of all HIDs is an electrical arc, flowing between two electrodes in the bulb in a glass "bubble," or arc chamber. This converts electrical energy into light. Read more about this on the HID Bulb page.
The bigger the arc, the brighter the light! The key factor in brightness is how much power is flowing through the arc. The more power, the bigger the arc, and the brighter the light. The color of the bulb is important in determining the total output. An HID bulb produces many different colors of light, which are combined by your eye to create the white light you see.
In addition to the visible light spectrum, HIDs also generate some ultraviolet light, which is not visible. The brightest bulb color is K, as it produces the least amount of UV light. You can see almost all of the light that is generated. To achieve a "cooler" or bluer color with HIDs, the bulb is designed to output more blue light. However, as the color output shifts more to blue, more UV light is also produced, which is not visible! This is not a major issue with cool-white colors, but deep-blue HID bulbs will waste a lot of light output, because they will be generating so much invisible UV light.
No reputable company will offer deep blue or purple colors of HIDs, as they do not produce very much visible light. Additionally, white is the only legal headlight color in most areas. HID bulbs are not perfectly efficient at converting electrical energy into light.How to make sure the HID kit will work properly every time.
Both HID bulbs keep flickering and making clicking noise. Check to see if the battery of the car is too old or almost empty as this can cause power distribution issues. If your vehicles low beam has the daytime running lights feature please make sure to disable the feature before installing the HID kit. Double check to see if you purchased the appropriate bulb type for your vehicle.
Some vehicles require an adaptor to hold the bulb in place that can be custom ordered from us ex. Please contact us for information. HID turns on then both sides go out.
There is a possibility that the fuses are blown. Please check your fuses box according to your vehicle's user manual and upgrade the stock 15 Amp or 20 Amp headlight fuse to 30 Amp. HID will only work when the high beam is turn on. Make sure you have plugged those three wires correctly to their positions. Usually the combination is Yellow, Black and Red. If the issue persists, please contact us for a diagram. Inside the HID ballast, there is a micro chip which is used to detect whether there is any potential problems.
Any potential problems such as sudden high impulse or shortage of power input from battery or extremely high heat will trigger the self-protect and shut the ballast off temporarily.
It takes about 3 mins for the micro chip to reset itself and the ballast will be working again. Once this happens, please turn off the HID and wait about 3 to 5 mins. Therefore, the only way for such cars to install the HID kit is to install a canceller cable. One or both light can't ignite initially.
Bulb turns off after the vehicle just starts. Only one light works, even though both lights are installed exactly the same. Check all connections between the bulb and ballast. Check the bulb that does not work to make sure there are no loose wires. Check the fuses. Use at least 30A fuse if the stock 15A fuse blows. If the issue remains, the bulb may be defective. If the issue remains, the ballast may be defective. If the HID system works properly, your vehicle connections, battery, alternator, etc.
The colors or lighting effects of the two bulbs are different. The leveling of the headlight housings are not even, adjustment of the headlight housings is needed.Login or Sign Up. Posts Latest Activity. Page of 2. Filtered by:. Previous 1 2 template Next.
Tags: None. April 15th,PM. Are you talking about an brand new hid kit? If you aimed both headlights properly, wiring is fine and both bulbs are a matching pair with same age, then you got a defective low quality hid kit. Comment Post Cancel. All or nothing, either the arc is ignited and produces full power or no light is emitted at all.
Check the hid bulbs, maybe one has the film on it still. Or just a defective bulb not igniting as it should. Good luck. Try switching ballasts and or bulbs to the other side of the vehicle. If just switching the ballasts move the dimmer lighting, then you may have a bad ballast. This is usually expected from aftermarket hid kits.
Hopefully you could return them and get oem parts. April 18th,AM. Very old thread I know, but did not want to start a new thread since this one was related to my issue Setup: FX-R 3. Based on the picture below you can see that my driver's side bulb is dimmer than the passenger side based on the cutoff ft from wall. I know there is over lap between the two projectors which will make the passenger side look brighter, but when I stand in front of each projector so that only one projector illuminates the wall, you can see a significant difference in light output.
When I cover the passenger side projector, the driver's side projector illumination looks exactly like the upper left corner in the cutoff picture. Below is a list of correction actions that I have taken, but have not resolved the issue.
No matter what I have tried the issue is always on the driver's side. All 4 headlight fuses were replaced about a month ago -Doubles checked all connections on relay -Ensured the bulb was seated properly in the projector Now I am at a loss on what my next step is.
To me it seems that the ballast is not receiving adequate power supply. Both bulbs are K, but when I am close to the wall you can see the passenger side has a yellow tint and is very bright like a K should be.
The driver's side bulb has a 5k look to it if not higher and it is noticeably dimmer even when swapping ballasts and installed a new Mori D2S bulb. Not sure if I need a new relay harness. Last edited by dmanns67 ; April 18th,AM.Yet anyone who has the responsibility of maintaining these lighting systems, knows that sometimes metal halide can be very expensive.
Not only from electrical consumption, but the cost of light bulbs, ballasts, labor and often times lift fees can be very tolling to a businesses bottom line. Like any light bulb, Metal Halide lamps offer significant signs that it is time to replace a light bulb. Unfortunately, most people do not take the time to notice the warning signs.
First we must understand, that the only light bulbs that can be run to their hard fail point is incandescent and halogen light bulbs. Any light bulbs or lighting system requiring ballasts, is NOT designed to run until a lamp burns out completely. Failure to replace a commercial light bulb before complete lamp failure will damage the ballast and cause a drastic increase in maintenance costs. In the case of Metal Halide, most manufacturers rate these HID light bulbs with a life of approximately 20, hours.
At this point, all lamps should be replaced. This is known as color shift, a natural effect of Metal Halide over long periods of operation. Usually the lamps will gain a pinkish hue when compared to other lamps in the same system. This is caused when metal vapors in the lamp are expired from heat or burning, and the lack of a particular mixture in the arc tube renders a different color.
The lamp needs to be replaced as continued operation will damage the ballast. Once a new lamp is installed, the metal halide bulb will light and come up to full brightness. However, this is not the correct repair. The ballast in an HID lighting system requires a capacitor, this is a current limiting device that prevents too much amperage to be delivered to the HID bulb.
As a metal halide lamp ages, it will require a greater load to maintain illumination. Because of the extreme heat produced by the HID system, the liquid gel that fills the capacitor will crystallize and change the electrical characteristics of the capacitor.
At this point the capacitor is providing a low power factor and delivering a higher current than designed. The metal halide lamp will receive an unrestricted current amp draw and become brighter until it cuts out again. Then the thermal switch will cool, reset and the cycle repeats. This will prematurely fail the new replacement lamp and result in heavy blackening of the arc tube.
The ballast, capacitor and lamp need to be changed.Forum Rules. Timeslips Advanced Search. Page 1 of 2 1 2 Last Jump to page: Results 1 to 15 of Thread: HID Headlights not as bright anymore. Thread Tools Show Printable Version. HID Headlights not as bright anymore. For a while now I have noticed that my hid headlights are not as bright anymore.
I have a relay and the capacitor hooked up to them. I noticed this about 6 months agot but I really noticed when I was driving next to my buddys charger who has the same hid kit and his was brighter. We have the same kit k. I swapped out my bulbs and ballast and still not as bright.
I have had HID's in my charger since and swapped out bulbs and ballast when ever they go bad. My first thought was to check the wiring, check the ground, etc because I have the same relay kit, and capacitor on there for about 5 years now. Anyone else experience this problem? This weekend I plan on trouble shooting, adding a ground to it to see if it is a groung issue not sure what else it could be.
Are you headlight housings dirty or hazy? If you can solve your problem, then what is the need of worrying? If you cannot solve it, then what is the use of worrying? Pm Papito he's the man for the task to ask!!!!!!!
New ride challenger Srt All black emblems,hellcat airbox. I even ordered new headlights because of this. This weird! Its been going on for months now. I'm thinking of just ordering a whole new relay harness, and capacitor and rewiring everything now.
It seems like you only realized that your lights aren't as bright as they used to because you were riding next to your buddy. Here is some info on HIDs: The have a life span, and over time they lose some of their light output. Changing the relays, ballasts and any other component would not change anything.
Next thing about HIDs, is that every single set of bulbs can never be precisely calibrated to match one another. They can come close, but they will never technically be identical. Although you and your friend purchased the same color temperature, the color temperature of k from one manufacturer can mean iceberg blue, while another manufacturer's k means dark blue. There isn't an actual universal scale to calibrate the color and light output. If you want brightness, I would suggest k or k. Let me know if you have any questions!
I completely understand what you are saying, I knew my lights werent as bright as they used to be. You can really tell when I was next to his car but even he has rode in my car and sees that my lights arent as bright as they used to be a few months ago.
I swapped out the ballast and bulbs twice now and still have the same result.And the winner is… LED headlights. While halogen bulbs have been the norm since the car was invented, over the least two decades they have been slowly replaced by HID bulbs, and more recently LED bulbs.
The image above demonstrates a clear advantage of LED headlight bulbs. This example uses the headlights of an Infiniti G The Light intensity is quite weak for the halogen and HID, while the LED bulbs have a very tightly concentrated, focused beam right near the center, with a strong curved beam emanating from the center.
Also, the color is higher on the Kelvin scalecoming in right around a K color, while the HIDs are closer to K, and the Halogens at a K or so. Headlights whose light output most closely matches the color temperature of the sun tend to be the most effective for the human eye. LED stands for light-emitting diode. Instead an LED transfers current through a semi-conductor.
This movement of electrons generates light. One advantage of this form of light generation is that by adjusting the material properties of the semi-conductor, one can adjust the frequency of the emitted light, thus changing its color.
LEDs have been in use for decades. Their small nature, and low power consumption make them perfect for such applications. Additionally, in low current applications, they also generate minimal heat. Because LEDs can be manufactured in various sizes, several nifty applications have been developed with them. Audi for instance had a headlight on the A8 that had 25 individual LEDs per headlight. This system allowed them to dim certain sections of the light while allowing the rest to remain bright.
What this entails is that the road directly in front of the car can remain brightly lit, whereas areas occupied by oncoming traffic have only a dim light shining at them. This results in an overall safer environment for night driving for all road users.
The aftermarket LED scene has two sections at the moment. The biggest is the replacement LED kit option. This comprises of LED bulbs that are shaped to be drop-in replacements for conventional halogen bulbs.
The alternative is purchasing an entire new headlight fixture. This is significantly more expensive, and the LED kit option is thus much more popular. It also requires the least modifications to your car. Both options require additional electronics between the car and the light. This is often referred to as the driver. The main reason for this is that LEDs operate at a lower voltage than the conventional 12V that a car provides.With that in mind, it can be tremendously useful to start off by looking at whether both, or just one, of your headlights have failed, and whether or not the high or low beam mode still works.
When headlights stop working, it's usually an electrical problem or an physical issue with the bulbs themselves. In order to get to the bottom of the situation as quickly as possible, it's important to make note of exactly what type of failure you have experienced. Based on which bulbs have stopped working, and under what circumstances, you can use the following information to narrow down a solution:.
Most total headlight failures are caused by a bad component like a fuse, relay, or module. Wiring problems can also cause both headlights to stop working. If just one bulb fails to work in either high beam mode or low beam mode, it may be the bulb. Most headlight failures that are limited to just high or low beams are related to a relay or the high beam control switch. If your headlights always seem dim, the problem could be foggy lenses or worn out bulbs.
If your headlights seem to dim during specific circumstances, there may be a charging system issue. Other headlight problems are also caused by some combination of bad bulbs, wiring or relay problems, and bad switches.
Most headlight systems are pretty straightforward and include a few basic components like the bulbs, a relay, a fuse, and a switch. There are variations on this basic theme, like some vehicles have daytime running lights, adaptive headlightsor other little wrinkles like fog lightsbut the idea is still the same.
When you turn on your headlights, that switch activates a relay. That relay, in turn, actually provides the electrical connection between your headlight bulbs and the battery.
HID & LED Troubleshooting Guide
Fuses are also involved in order to provide a sacrificial failure point to protect the rest of the wiring. In the same way that your headlight switch activates a relay to provide power to the headlights, operating your high beam control will generally activate a relay to turn on the high beams.
In the case of dual filament headlight capsules, this literally sends power to the high beam filament. If any of these components stop working properly, your headlights will fail. And by looking at the way they failed, you can usually backtrack to figure out the best place to start troubleshooting. Fixing a burned-out headlight is usually a pretty easy job, but there are cases where you may want to go straight to a mechanic.
If you don't own some basic tools and diagnostic equipmentlike screwdrivers and a voltmeter, then you may want to think about taking your car to a professional during daylight hours.
