Is this a Pulse Start Ballast?

Don't know what pulse. Refers to but I can say it acts like any other ballast I've see , that's non switchable , it stays nice and cool as well

I'm not sure, we live in Texas, we have not experienced any problems with the ballast, but the problem would be with the bulb warmup time. Good luck

It is called a "TCP 4001 Hardwire Base for Circline Ballast." I do not believe there is any circuitry in the base. The base seems to just be a socket to feed the 2 pins 120VAC.

play around with the ballast connections. when i setup mine, ballast connectors caused the same issue.

The bulb does not care what the ballast runs on. You need to search for a ballast which accepts 220-240v. Good luck!

ballast is bypassed, would not work. I'd suggest labels for hot and neutral too.

Please make sure your igniter and capacitor is well maintained on magnetic ballasts, and make sure the electronic ballast of your choice is designed to ANSI standards electronic characteristics. http://www.ushio.com/files/specs/hiluxgro.pdf

Not from within the ballast itself, but I have heard that sound come from brief arcing at other locations. Ballasts deliver a brief (~ 1 second) pulse of high voltage (~900 VAC or so) to initiate conduction in the tubes. That voltage is high enough to arc-over wherever insulation in the fixture may be compromised due to humidity, age, contamination, etc. The sound might also be due to arcing in the light's switch (in the wall) if the contacts are worn or displaced. Or it could be the sound of arcing at the terminals (pins) of the tubes themselves if they are not fully seated in their sockets. It may be due to a bad or missing ground at the fixture - rapid-start electronic ballasts like this one need a good ground to operate properly. You might want to have a qualified electrician check this out for you to ensure everything is safe. Good luck!

Yes, it's the ballast warming up. The sound should diminish somewhat but will still be hearable if you're real close.

Absolutely Not. No it does not work with any of the new digital or electronic ballasts. It only works with an old school ANSI 52 Magnetic Ballast.

I found it was just cheaper and less trouble to replace the ballast. I also discovered that the ballast life depends upon whether the lights are off when the starter is actuated. If the lights are on when my starter is actuated, it causes a low voltage/high current situation in the ballast nearest the battery. I had two units from different manufacturers fail like that before I figured out what was going on.

Never had that happen before, and I ran it for 18 hours a day for a month. I would get a new one just to be safe. And if the problem continues make sure everything is okay with your ballast. It really isn't risking it with the amount of voltage these things run at.

Nope no ballast just plug in a regular outlet and your good to go. compared to a cfl just depends on your needs and situation. if you want better light penetration I'd say the hps butifyou have to keep temperatures down I'd go cfl. this hps has a bit higher wattage so it will increase on energy costs but very minimal. overall it's a great light with great results in smaller growing areas. Keep in mind also that this is used for flowering and not vegetation. Depending on which stage your plants are in you'll want to consider that. Hope this helps.

i order this kit but did not receive the ballast ? do it comes in another kit?

No you won't. The ballast is like a fuse. If anything will fry it will be the ballast.

maybe your talking about a ballast resistor, i"d call MSD ask their experts.

I'm not sure... We've never had that problem. Could be in the ballast. I suggest contacting the manufacturer.
