I've seen those in Hingham, MA

Does anyone know how I can wire this fixture up to like a Dryer outlet? It's a 240 volt ballast, and I can't light it on a normal outlet.

Anyone have ideas?

buy a dryer cord and use the black and red wires as you "hot" legs and white as your neutral.

I was explaining to him about how the residental system 240 volts works...I was explaining to him that there is a Line A and a Line B....and I was not 100% sure if this would work....but I do know that you connect Line A to one wire and Line B to the other wire....using no neutrals in the streetlight.....(but be sure to ground the streetlight which is the bottom prong) But I wanted a 2nd person to confirm since I never done this thing!

My Dryer outlet is a three prong, so it's older.

wait wait wait wait.....you shouldn't connect both A and B together......that will cause sparks! That's bad!

My Dryer outlet is a three prong, so it's older.

then buy a 3 prong cord then. the two outside wires are you 120 volt legs and the center wire is your Ground.

I got this to light up! 8D I used a three-prong Dryer cord and wired it to how Jace told me to wire it, and it lights up just fine!! It is brigtening up right now.

I am glad the ballast works!!

Isn't there some way to use certain 240v ligths on 120v?

Sure, hook it up through a transformer rated for the current.

I meant directly. I thought I heard talk about that a while ago either here or on the LG.

there sort of is...but dangerous and ILLEGAL!!!!!!! So even I wouldn't do it...

Well there is one way to do it,(DON'T DO IT) I saw an ad online for a converter box to 240v that used two power cords. Basically you were supposed to plug the two cords so that one cord is on line 1 and the other on line 2 so that you get 240v...not what I call safe and I'm pretty sure it's not approved.

How is it dangerous? I was thinking one could wire two entension cords to it and then they'd have 240 but that seems too easy.....

I believe there are rules against having equipment with more that one power cord on it so those 240v converter boxes aren't allowed.

How much does a LEGAL transformer cost?

Not sure I'd say around 35 for a 500w one and 70-100 for a 1500w one.

If BOTH of the 120V charges draw exactly the same current, you can plug them in series directly on 240V and it'll work! They MUST draw the same current though!

But in no way this setup would be compliant nor safe XD.

Ummm Vince...I donno what you are telling me.....are you talking about using 2 different lines (the Line A and Line B) in series...BAD IDEA! That's probably WORSE Than the other way Joe mentioned...but also a dangerous idea too! You most likely will BLOW your outside transformer if you did it in Vince's way LOLOLOLOLOLOLOL
