Do these have to operate on the same Phase of a 220 volt service or either Phase

Hi, The system I have is a three phase system. Two incoming 72 KV lines into two large transformers create the third phase.I use the units on both 125 V phases. It seems that the signal does not have problems to run through both transformers.I hope this is useful for you. I know there is a cross-over unit if it gives problems to go from one phase to the other.K.R. Tony

I finally installed them. 1 in the barn and 2 in the house. They did not work in the first plug I used in the barn. I moved the one in the barn to a different plug which is on a different phase and they worked like a charm. So I would say YES they need to be on the same phase.

Why would you need if both voltages same. It will convert 240 to 120 or 120 to 240

This unit is 110V only so will not work in your situation. I'm not sure they are made in the 220V flavor...

It will depend on how you want them controlled,and if they are on same frequency. More information is needed

All of the outlets here are 110, and those bulbs worked well for us everywhere that we used them. I never tried them in a 220 outlet, but 110 appliances will usually be destroyed if you plug them in to a 220 outlet.

that is correct. if you connect them incorrectly nothing will happen. the voltage output will be one or two volts. if you connect them correctly you should get 18 volts. good luck.

Yes, they should on/off switch anything up to 25 Amps 250 Volts. Our main use has been heating elements in various furnaces or band heaters. You need 2 to switch 220-240 volt systems since there are 2 hot lines at 110-120 volts each to make up the 220 volt power. We do have one switching a 110 volt air conditioning compressor on & off.

Honestly this is not my background. However this unit operates on a 220 circuit, hence the reason for the different plug style. Personally I would leave plug as it is and not mess with it.

No. You have to hook them up to a switch or run them off another power source.

This should not be a problem. I am currently using it with 200A 220V service.

Hi and lo get the same voltage. Need to get the rectifiers for no light flicker. Mine work great!! Happy trails!

I do not know for sure, but they all operate on the same frequencies. Most likely you can. Ours work great.

I'm not positive but I'm pretty sure the same bulb works on either voltage. Google it...

These have voltage switch on the back. So make sure to adjust according to your location!

These run on 12v direct current. You need to install a 50e max 120vac-12vdc transformer to do the job

This is for use on 110-120 VAC, 60 Hz., 6.5 amps, single phase. It will not operate on 220-240 VAC.

Probably. Unless you use a transformer, you'd need one that was designed for your electricity voltage and cycles.
