Convert 240v plug end into 120

Is it an automatic sensing driver for the voltage? You might have to move a switch or re wire the driver if it is a multi tap to 120v as well.
Will this safely work on all 240 v fixtures? Even 1000watt de/se HID setups?

No. Not all 240v stuff will work on 120v. Only some. You must look where the cable enters the device, to find the information.
yes, They're made for use on USA 240v/120v plugs only.. Some fixtures come with them instead of 120v cords.

The little switch to move transformer taps is getting pretty rare now. Very little kit comes with such a transformer now. It's a lot of metal to make one, which has somehow become more expensive than using some sort of smps, now that high voltage semiconductors are plentiful. I find it odd that we can be knocking out electronics, cheaper than a foundry can make transformers. A part that's still actually in most things, just smaller as they are more efficient at higher frequencies. Still had to make and wind one though. The price of power electronics is just so cheap now. 20 years ago I had a monster of a car amp, so big the local broker refused it existed, and wouldn't even come to my car to see. He insisted he had the UK's biggest himself. Now, 20 years on... it's barely worth having. Something half the size and half the weight, is twice as powerful and doesn't even have a heatsink. Closer to home, the weight of a 600w ballast, verse a 600w driver, makes the lack of a big lump very noticeable. I don't think we will ever see an LED driver that needs a physical alteration to change input voltage.
Loved that car amp. 90 amp of fuses would blow every couple of months, and a few outputs and fets every year or so. I still have it, though it needs another handful of transistors and fets. The other amp was 60 amps, and blew less often. That still works..
2000w of fuses blowing, is a better guide than the numbers they print on these things. 20K? lol
NOPE.. That was on you lol. 240V only will never work on 120v ever !! You would need a voltage converter. I got some adaptors with my 1KW CMH fixture. Those adaptors will not work on EU plugs, it needs another adaptor. has zero do to with the fixture itself. Ive not seen 120v-only fixtures in years. Most if not all work on 120-277v Auto sensing. Old stuff had a switch nothing ever needed rewiring. IT WILL SAY ON THE SIDE WHAT THE WORKING VOLTAGE IS. You cant plug 120v into 240v or the other way with a different cord end. That is why we use the adapters. If you read his post he was asking about the adapters. Any electronics with a range of 120-277v will work safely using those adapters if plugged into a wall outlet of 120v or 240v, .

It's a plug adapter. It doesn't turn 120v at the wall, into 240v for the device. It just moves the pins about, to fit a different receptacle. It's nothing more than a travel adapter. It passes the 120v through it, to your appliance. If your appliance doesn't work on 120v, it's of no use. Though wouldn't be dangerous in most cases.
Just seeing a pic does leave room for confusion, so here is a link to one for sale. They go to lengths to explain it won't make a 240v item work from a 120v outlet
You are going to have to edit the post before the one you just edited, if you want to cover your tracks properly.
That's sleazy guy. Your posts original version is quoted above. To change it is one thing, but to try and turn it around and laugh at me?
There are no words for that.

Dude. you obviously do not understand how the adaptors work. Go read a book. My above post explains it clearly. Of course that adapter won't work on 240v it's for a 120v outlet.. All it does is cut off 1 hot leg for use on 120v. It doesn't use a neutral wire just 1 hot and ground. 120V to 240v adaptor combines both the hot legs together to produce 240v needed. All these do is move the wires inside nothing more. The fixture's 120-277v ballast does the conversion.

The question was if it will work on all 240v lights, including the 1000w DE's
You said yes.
Will it work on this one then?
The answer is no.
Your center tapped delta windings are no mystery to me. If you feel they support your answer, It's not me that needs a book. It's entirely irrelevant.
If the wall only provides 120, and the light needs 240, then no amount of swapping wires around is going to help.
However, if the wall provides 120, and the light will run on 120, then it's all good.
No degree in electrical distribution systems is required. All appliances have an information plate near where the flex enters. They tell you the operating conditions. Without this plate, items fail basic visual inspection. They are not approved for use, at all. We have this plate, to see what power supply it needs. It's really quite elementary.

you need the 120v/240v and it will work
