Build your own HID-Ballast - Page 3

mathias · 14th November 2003, 03:37 PM

Yes the Ignitor is a normal "starter" and yes the HID flickers some time before it´s starting. In the starter there is already a cap to reduce EMI. The HID-bulb needs a wider startingpuls than a normal fluorescent-lamp does, so thats why you need the cap. The ballasts are made of iron, and they are heavy. I want to help you with 120V but I don´t know what kind of ballasts you use in USA.

guess the US has got iron ballasts as well...on the topic of starters...can I use a "flicker-free" kinda electronic starter...?? I dun see the 18uF cap in my home lighting..so I'm asking what izzit for??

Anyone know where I can get HID ballast for that cheap in US?
I plan to duplicate that Korean ATX PJ design, and I was planning on using a Xenon setup with the actual headlight reflector casing. but its over $100 on Ebay.

I have tried an "electronic starter", but it didn´t work, it went dead quite fastly. Anyway the "glow-tube starter" works very well with the 3.3nF cap, it starts the HID in a couple of seconds.

The only reason why there is a 18uF cap is that the ballast is a inductive load and to compensate that you put a capacitor in parallell with the powernet, the result will be a normal lamp load on the powernet. But the reality is as normal diffrent from the theory. The thing is that they don´t sell that cap. So I don´t use it myself. The result will be that it takes more power. If you put up four fluorescentlamp, there will be the same problem. So never mind the 18uF cap.

so the 18uF cap actually helps to save power here? Hmmm...wanna try it out and see if my utility bill drops...hey if it works I owe it to you guys~!!!

i couldnt get that link, but i went through the home page, and saw Description:350 Watt, Pulse Start, Metal Halide, Sola Ballast
is that the one yo meant?

Also, in Home Depot I saw a High Pressure Sodium flood light kit, does anyone know how much heat they put out?
