This may actually have 120 volt tap......some of my streetlights can do 240 volt when wired differently...note the tag on this streetlight said "Wired for 240 volt" which its possible it may have 120 volt feature.....he will need to look at the diagram...

Hang on! Thats a 250 watt ballast Thats tiny!

It is possible to run a 240 volt light off of a household voltage 120 volt if it has a two wire set up assuming that it has a hot and neutral wire set up, I've done that before with 240 volt lights.

If I'm right, a dryer or stove outlet could also be used as a 240V supply. I'd take the dryer, 30A is enough.

Yes however you would need to combine both the hot wires

I had a 240 volt streetlight with a three wire set up two hot wires and a neutral wire and unfortunately you have to run those off dryer or stove outlets.

hey rych is the White Squareish thing an ignitor?....sure looks like one...in an ignitor socket too.

i really don't know

That is an ignitor. Looks like the kind I have in my m-400 r2. Just a bit different.

Yes and it is a plug in ignitor making it easier to replace if ignitor goes bad.

The ballast look like series choke type, so it would work for only 240V (and above, if it show signs of more voltage taps)

the Ballast is Quite dusty eh Rych?

welcome to az

A lot of ballast I get are pretty dusty and dirty and filled with toasty crispy bugs....including bees and ladybugs!

It seems the plug in igniter base is also where the Power-Door plugs in

this was above a very busy street also infront of my work

Got to get the industrial fan to blow all that dirt off! I thought it was rust in the thumbnail.

Use a air compressor blower....that's what I use....It blows about 80 psi when full of air......that machine is really loud when it fills air!

I would like a bracket like on this powerdoor or my M-400 a2. I dunno why some M-400 a2 powerdoors have brackets that hold the ballast and others just screwed directly in the powerdoor.

yeah compressed air is good,unless you want to remove all electrical components and hit it with a high pressure blast of water.
