Sorry if this has been asked already... In the future, I'd like to run 2x1000w lamps from a single (most likely) 15a circuit. I've been looking at some plug in step up transformers that'll take me from 110/120 to 220/240. Is this an acceptable way to get more amps out of my circuit? It looks like these units just plug right into the socket.

Cheers

you can always get the same power. if you have 110V/15A you can get maximum 110*15=1650W. it doenst matter if you transform it to 220V (7,5A) or 1000,000V (1.65mA). youll always get these 1650W because wattage in = wattage out.

Hey electrician. Quick question : what's the real deal on Lumatek's "Super Lumen Switch"? I've searched around the net, and lumatek doesn't even have much to say at all.As a matter of fact, they don't really have much detailed info about any of their products. I've always used regular ol magnetic ballasts and I'm beginning to think I wasted my money investing in digital technology recently.

I understad that the wattage will be the same, but since there is a step up in voltage AFTER the outlet, my equipment will draw half the amperes, correct? So instead of a single 1000w @ 110/120/(9A) it would be 2X1000 @ 240v drawing Approx. 4.5A each. Am I off base? I do see what you're saying about the ratio of total power being the same, but my issue is keeping the amps low so I don't trip breakers. The issue here is, the original circuit was designed to draw around 1700W as you stated. With the transformer, I'll be able to use about 2100W. There in lies my question. Is this safe?

*ONLY* if your transformer is running at 100% efficiency, which is impossible at this point in time. If that xformer gets warm/hot, its wasting power.

The step up will draw twice the amps it putting out. Like he said, watts is watts. The amps *after* the step up will be halved, but will be doubled before it.

Using the step up will actually cause you to use *more* power from the wall. The transformation isn't power-free.

Got it. Looks like I just have to run a line from the 220 outlet. Thanks.

Can anyone Help me with wiring my CFL's?

The sockets i'm using have a silver and bronze screw on one side and two bronze on the other side of the socket (see attached diagram) . I'm trying to wire it to some 16/2 lamp wire and plug and from what i understand the two bronze on the right side are hot , the silver screws on the left is neuatral but idk what the other bronze one on the left is. So with only having two wire idk what ones screws to use.

im not sure but usually you have the hot lead, the ground lead and a nuetral lead. white is hot, black is nuetral and green is ground. the green is not needed its for safty more the function

its higher electrotechnics. but i can tell you if you have a two phase system, the voltage between two lines is (voltage to earth)*sqareroot of 3.
so if you have 220V between two lines youll get 220V/1,73=127,17V. if you want to be really safe buy equipment from europe. it runs on 220V to 240V.


it should work to connect this line to socket and make a bridge from neutral to earth. but its dangerous (can become dangerous) without using a residual current device.



you can put maximum 6050W on these socket: 1650W on 110V and 4400W on 220V.

are you, lahierba, fucking insane?

european power distribution runs @ 50hz

north american voltage runs @ 60hz

you would have people burning down there houses and potentially causing great amounts of damage, personal injury, and loss of life?

have you ever seen what happens when you put 50hz equipment on 60hz voltage, or vice versa? theres a fucking explosion....................................

...the bastard electric company just installed a smart meter at my place....Will my 1000w Lumatek put off RF interference and disrupt the new meter? ..do I need to build a faraday cage?

hello man, how are you?

sorry to boring you but, can you tell me if i really need to usa a ballast for a 250w HPS lamp what does it do properly.. the ballast.

thank you, wait for repply.

I'd like to ask a couple questions. So I am setting up a grow in my shed which I am going to have to power. I'd like to know the steps I need to take to run from my fuse box to my shed, to support 4 1000w lights and balasts, an a/c unit, water and air pumps, and vortex fans, and maby lights t5's for a cloning station. Every thing is 110, not sure it makes a difference. Any input is greatly apreciated and thanks for your time.

heyy everybody, i gotta question tht doesnt necessarily pertain to the grow room..
but figure somebody lurking here might be able to help.
my computer crashed a while back, just got my hands on an old windows 98. but i want to upload pics of my ladies =) but no usb ports on this old junker.... haha
is there any way to put a usb port in a computer this old? or is there some gadget to put a memory card in a floppy disk and do it that way?
any opinons would help alot!! im no computer wiz, well frankly im lucky i got it setup and connected to the internet haha
peace out
