A ballast is a device that specifically regulates the current. They are used in nearly all types of vapor bulbs. (that means fluorescent, metal halide, mecury, hps and hid). The reason they are used is because, and go look this up smart guy, a vapor lamp requires high voltage to ignite the gas inside, but a considerably lower voltage to maintain the spark. Ballasts use inductors or electronic limiters to maintain the currect current flow when the voltage drastically changes.

Your assertions that 700 volts would kill is plain wrong. You can be hit with millions of volts and not be hurt one bit. the killer is the current, which is inversly proportional to voltage. 14V @ 1A => multiplier => 140V @ 0.1A. It also depends on the frequency. A very high freq wave will bounce across your skin. Oh, and static... when you shock your tard ass on the door knob, measure around 3KV.

I suppose when you looked all this stuff up... you didn't bother to actually read it all. Here is a quote from your wikipedia page:



The reason you are seeing it called an "inverter" is because CCFL are typically ran from a DC (battery) source. Like in cars, computers & such. The multiplication of voltage using a transformer or cascade multiplier requires AC. So the DC input must be "inverted". However, that term is somewhat misleading as well. There is no "inversion", only a method to produce a pulsating wave, which for the most part acts like an AC sine wave in the circuits.

Cliff notes?

it is an inverter and not a ballast:

Ugh... this is like trying to explain quantum mechanics to an english major. You're wrong, but don't know enough of electronics to know *why* you are wrong. Go back and read the first things you posted to me... from wikipedia. It explains exactly what a ballast is.... and that they are used for gas-discharge lamps.

Let me try to explain it this way: You insist that it is only an inverter. That is simply turns the DC into AC. 14Volts @ 0.7 amps. And that voltage/current is enough to excite the gas into an arc of plasma - producing light. Well... think about alllll those sockets in your house. They have 120VAC and upto 20A at a single plug. If 14VAC could ignite an inert gas, the voltage from your outlet would also create an arc between the contacts - BUT THEY DON'T.

That is because to excite a gas to the point of plasma requires very high voltage. To even get a visible spark takes thousands of volts! This is the same reason you have an ignition coil in you car. It works JUST LIKE A BALLAST. It produces around 10KVA to provide a spark at the plug.

As for your "proof": That little black box could have "Jesus Christ" printed on it - I wouldn't expect it to turn water into wine.

LOL... did you even LOOK at the picture? The right side OF THE BALLST says "H.V. DANGER." Since it takes about 30V to break skin resistance, you wouldn't feel anything if you touch the output side of the ballast... that is... if it actually is just the inverter you claim. Go ahead and touch it, I dare you. hahaha


By the way: The International Electrotechnical Commission and its national counterparts (IEE, IEEE, VDE, etc.) define high voltage circuits as those with more than 1000 V for alternating current and at least 1500 V for direct current, and distinguish it from low voltage (50-1000 V AC or 120-1500 V DC) and extra low voltage (<50 V AC or <120 V DC) circuits. This is in the context of the safety of electrical apparatus.

In the United States 2005 National Electrical Code (NEC), high voltage is any voltage over 600 V (article 490.2).

And FYI: The dielectric breakdown strength of dry air, at Standard Temperature and Pressure (STP), between spherical electrodes is approximately 33 kV/cm.[1] This is only as a rough guide since the actual breakdown voltage is highly dependent upon the electrode shape and size.

i just installed my ballast/inverter thingy from vibelights.com...is it suppose to get extremely hot??....keeps getting hotter and hotter...not sure if thats normal....my last one died righ after it got as hot as this one is...

are you sure you're not reversing the polarity of the input???

be absolutely sure you are connecting the wires correctly. ie: black is ground (-) and red is positive. what size fuse do you have in the fuse holder?

lol. yes! 1.5A at MOST (the ballasts are rated at a maximum of 0.7A each) There must be something else wrong with your setup... can you describe it to me exactly? maybe take some pics?

give me a second...ill try to find some pics from this forum...its the same basic setup everyone on this forum has for there angel eyes...it came with a 5amp fuse from umnitza.com when i purchase it...that why i been using it....ill be back

heres a shot of the setup i got from another thread


this second pic shows the inverter/ballast....the four white wires that are paired i think might be the problem...the reason why is because the connector doesn't fit with the original wires that come out for the angel eyes...i just cut them and put them together...they don't say which one is positive and negative so i just guessed...could that be the issue?

they should know better than to give you a 5 amp fuse with those ballasts... the ballast will blow long before that fuse does. that's rather irresponsible in my opinion. (look at the picture above, note how the ballast says "0.7A max" under the input side.

the white wires don't have a polarity (+ or -). because of the nature of high voltage, it is somewhat moot. anyway, there may be a problem with your relay. it could be shorted internally. are you absolutely sure you connected all of the wires correctly to your car?

I'm not terribly familiar with their harness... i did mine all on my own.

yeah its all done right...its been working for over a year without a problem..so the connections are right.....i have no idea what it could be now...ill check the relay...how would a be able to know if its not working correctly??in other words what are the signs of a bad relay?

to really test the relay, you'd need to use a miltimeter to make sure it was working correctly. you might want to go get a new relay (AND FUSE!). replace them and see if it happens again. also, I would only connect ONE ballast as a time and see if it gets hot. if so, try it on the other side. if it still gets hot, try the other ballast (by itself) on each side. let me know if/when they get hot or if the (hopefully 1.5A) fuse blows.
