Fc-e8000 220v power

I wanna run my lights on 220-240v to save some money. As they're listed to operate on an input voltage of 120-277v.

So, does anyone run their mars hydro light on 220-240v? If so, do the drivers automatically switch for power input, or do I have to open it up to manually switch power input? Thanks

Generally they switch automatically but efficiency may suffer on lower voltages.
This issue would be much easier to help with if you had info on what driver/s are being used but as per standard there isnt anything youd have to do to setup 220V input, afaik you just plug it in to mains and thats it. It will sense voltage, ac/dc etc but i cant promise anything about Mars.

"but efficiency may suffer on lower voltages."

What do you mean by this?

I actually just got a reply from mars, they are automat switching (sensing).

Thanks

Wait. How you gonna save money by raising the input volatge?
Double the voltage = half the current, so the light will use have the amps at double the voltage. And your paying for amps not volts

Edit: watts are what your paying for

The led driver has an efficiency rating which varies with load and input. Generally, at least the popular meanwell drivers, theyre less efficient at making dc power output on lower voltage AC. This means that even though the output of the light will be the same, but the wall watts would be higher for low voltage input. However this depends on driver to driver, only talking generally.


Again, ask mars: what driver and is there a datasheet? All your answers would be in the datasheet, im 99% sure Mars dont make their own drivers but buys them from somewhere. So there would be some kind of datasheet from the mfr.

Unfortunately this isnt really how it works. You cant make 240V power outta 120V without spending some power on it. We would solve all power problems of the world if you could.

I think what you're saying is exactly what I'm trying to avoid... lower voltage less efficient 6.6a @ 120v
3.2a @ 240v

And I'll be using 240v directly from my panel with no additional transformers. According to the amps to watts calculator, I'll be saving like 60-80 watts per light at max draw. Not a huge savings but not nothing

Or am I missing something?

Edit: My math was off haha, it's more like 11 watts. Probably take me a year in savings to pay for the new plug and receptical. Not to mention the price of a 240v timer

I think you just confusing some details. You are paying for “performance” means kilowatts per hour. Difference between those voltages is just the current, higher or lower. At the end of the day, its about how long will last your diodes, so almost no difference on your electricity bill at all. Anyway, you want to transform voltage, but how and why? You may need different gauge cables and breakers an so on. I am not electrician but it does not make sense to me. Have fun

They do deliver with moso, inventronics and meanwell as well. It probably depends on year when the light was manufactured. My light was listed with moso on the website but came with inventronics and other one listed with inventronics but came with meanwell.
