I can answer alot of your HID questions. I do sell them as well. You will find that the units I offer you will not be able to get your hands on unless you dont mind a $700-$800 dump for the ballast alone............. PURE DIGITAL!
Anyhoot... Things to consider when buying. Any HID kit on a bike is a modification. If you by a "CAR" HID conversion kit such as mentioned PAY ATTENTION...
You will get a "MODIFIED" hid bulb sometimes called a CONVERSION KIT/BULB like you mentioned... H7 in this case. The base of the bulb is modified and flatened out so it will fit in the "stock" spring space. There are wires relocated and soldered onto the base of the bulb so that it can plug into the ballast...
PROBLEM: modified bulb means your replacement bulb HAS to come from them at THEIR prices so your fúked. Their bulb has a fancy "NON OEM/cant find it anywhere" plug on the end of it to fit "THEIR" kits. So next season when you need a bulb their not to be found. YOU NEED A NEW KIT!.
NON DIGITAL ballasts like described above are HUGE bricks. Vibration will "KILL" em in a heartbeat. If you get any moisture in it, it's fried. Location is tuff and you get "HI TENSION" lines that cant be bent or they arc, cant be lengthened or shortened and any mishap can melt your stuff down. No short circuit protection and most have to wait for the bulb to cool down to relight like old gym lights. Althought that may have been fixed.
The higher the "K" value in a bulb such as an 8000K describes how much "BLUER" the light appears. Generally 8000K bulbs are JAP made bulbs and tend to be a little less quality than the original OSRAM german made bulbs. an 8000K bulb that is described as "super white" has a problem. 8000K in the color spectrum is dayum near blue so if it's white it's not a true 8000K.
10,000K is pure blue. The more blue the least the amount of bright or usable light. 10,000K is like the blue lens on 3d glasses.
4300K is the brightest/best for motorcycles. 6000K is cute but creates false sense of shadows and you tend to miss the tiny moving things in your perrifial view where you need it the most.
All bulbs should be 35watts. MAKE SURE you get a D2R reflect bulb not a D2S or DS1 bulb. They are for cars with a prefocused lens like BWM has on the front. Your H7 is not a prefocused lens. Thus it will look bright but actually be worthless. Bean pattern is a must to be correct.
The units I offer are new mitsubishi pure digital ballast and the ballast weighs about an ounce. It's 4½x3½x½. It offers built in short circuit protection, it just shuts down till the short is removed to save itself. ASK THE Tyler who hi pressure hosed it directly and it still worked after the sparks. It has constant bulb temp measuring so it returns the light to exactly where it was at when it was shut off. SO INSTANT RELIGHT!.. a must. Uses 1/3 the amount of power/current to light. BUlbs are standard based D2R Osram 35 watt 4300K bulbs. Install is easy.
PS. check the price of a spare bulb then call me. Mine are $85.00. employee at BWM cant get em under $279.00 each.
Lastly......... I put mine on a paint shaker lit up at lowes and still works. A member here put it to the ultimate test and bounced one. STILL WORKED..
If ya need any questions answere let me know.......If your interested in one of mine thats good too. If not I will stear you to the best source to get what you want.
