Does this bulb require a ballast, or will an ordinary mogul socket suffice?

Yes. This bulb does need a ballast. This particular bulb is meant to run off of an 400 watt high pressure sodium ballast with an S51 mogul socket.

This light should not be used in a standard light socket because it could start a fire, the wattage is too high. This bulb requires a ballast for the safest and most efficient usage.

No, you have to get a socket with a 3 prong plug that is compatible to the ballast, which usually has a 15ft cord. This socket is made for mogul base cfl's.

Yes it does require a ballast. That was my misconception also. Had to send my bulbs right back.

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

Sorry Robert, I don't know about a ballast. Purchased the extra bulb from Amazon, have not encountered the ballast issue. Good luck.

The socket is hard wired to the hood, so while possible to retrofit for a 400 watt bulb/ballast, it would be cheaper and easier to just buy the 400 watt kit. Hope that helps.

I am not an electrician, but I believe that ballast is only needed for fluorescent lights and would not be needed for LED bulbs.

Yes, this is an LED Light fixture - no need for a ballast. The original were a small flourescent tube hence the ballast. It is actually a nice replacement - very bright. Good day.

It doesn't need one, it's LED. Only Fluorescent requires the ballast. Just disconnect and toss the old ballast.

You could use any 13W, 120VAC, 60 Hz, 220mA, 900 Lumens standard socket bulb. Multiple manufacturers make this type. Get it on AMAZON !

no i cannot be plugged into a standard light bulb socket. it needs to be plugged into a 4 prong ballast in order to work. some floor lamps uses these.

No it will not. The sockets are too small, the entire fixture is not wide enough to handle the additional size, the ballast is the wrong type as well.

Yes it does need a bigger socket which is a mogul connection. You can buy the Hydrofarm FLCDG125D Fluorowing Compact Fluorescent System w/CFL Bulb. It comes with the cfl for $57.00

This bulb will not work with an electronic ballast, only a magnetic HPS. This is a conversion bulb from HPS to MH.

The bulb will work in any standard socket, but make sure to keep it dry. As for light output it has a decent throw even for outdoor use.

Hamhock is correct; not to be found in your average retail store at all. Also, if possible before ordering- make sure it is the bulb you need and not the ballast! I bought two bulbs only to find out later it was the ballast which had failed, argh!
