hey man i need your help with some wiring im doing. i know you dont get online at this website alot, is there some other way we could communicate?

Nevermind I understood.

Thanks

I kind of confused myself with my question. I would like to know if I were using a 400 watt bulb on a 1000 watt ballast would I use more or equal power than a 400 watt ballast.

Thanks in advance

Is it possible to use a 400 watt bulb on a 1000 watt ballast? If so would you consume the same amount of power as if you were using a 400 watt ballast?

Thanks in advance,

on that Lahierba post

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.

I thought the purple part was what you were gonna hate. I saw something like that coming.

yea a resistor to control the wattage atleast some extra wattage resistence if ur having it on for little longer than usual. man.. my outdoor grow is crazy right now. there already almost five feet and i planted outdoor in natural soil in ground. they still got 3 more months... im thinking 7 foot atleast. nervous obout catching the sex before pollination. i live on the east coast nc and sc. When do you think they will start to show sex? i have 10 super skunk 10 mix and 2 swags. In depth detail if u can... thanks man

I was wondering if you could take a minute and check out my thread here:

You seem very intelligent when it comes to the electrical department and I'm in a little need of assistance :confused:
I'm going to be getting a variety of 1w 10mm LEDs and wiring them up and whatnot. Now when I put my info into this site it says there's too much power going to the resistors. From what I know one would just use a higher watt rating on the resistor so it can handle the 'load' correct?

You can read it more in detail on that page but I'm just curious if you could lend a word of advice, thanks if so!! :)

anytime man

cool, Im on it man... thanks for the advice. Peace!

wat going on.... so i have a couple questions for you. Im scouting a plot for 10 of the super skunk and 20 free variety from amsterdam. How much light minimum do you think it would need? soil looks good and im waiting on lab results. Also with scouting a spot just off in the woods.. what would a cheap way of preparing the soil fert. wise? Im in the N.C. area and have lots of land and good soil. Plan on germ. inside and then transplanting to plot... not comfortable with just throwing seeds out into the wild.

just wanted to stick with people who know there shit! got some outdoor grows coming in a week.. germinating now. would love the help along the way if possible! peace bra

I just tried to +rep you and apparently I have repped you to the max without realizing it. So thank you for your contributions and efforts here because they are of obvious significance. Your postings are what make RIU worthwhile. Thanks.

And about thermal management, how would you go about hooking up a little computer fan to the back of the PCB? Would you wire it into the LED circuit or into the power supply itself orr?

I was browsing around youtube and I found this panel this guy made, looks exactly like what I want just in a larger scale. Here they are:

It looks like his are rated for 100mA and mine will be rated at 300mA so I'm just assuming mine will be like 3 times as hot? Thanks again!

First off, thanks for pointing me more in the right direction. I've been searchin and googling and whatnot a lot more about series and I believe I understand the concept a lot more now. There are a few things that I'm unsure of though. You said both a heatsink and a fan would be optimal. Would you solder the heatsink to the PCB once the LEDs and resistors are wired up properly and then put a fan blowing on the heatsink??

And another one of my questions is: How can I make sure I'm getting a good enough power supply? Would this one work?? http://cgi.ebay.com/New-400W-POWER-SUPPLY-for-AMD-INTEL-PC-Computer_W0QQitemZ280461893569QQcmdZViewItemQQptZPCA_UPS?hash=item414cd4dfc1

It's rated at 400w and 15 amps at 12v, it appears heavy duty enough for a little 9 LED test panel. But I'm not 100% on that :P

my bad. I cant get private messaging down for the life of me. But what do I do with the remaining red wire? Remember the 12/3 i bought has 4 wires, as the trailer plug holds three. And I just need enough power to run a 600watter hps and a fan. But the distance is 215ft to be exact. The main thing im concerned with is if my electric bill will be affected. (besides the 600 watt power usage)

hey man. ran into an issue. was seeing if you could help. So I found out my trailer plug im using only takes 12/3 and 10/3 wire. So I had to go with 12/3 due to budget. My trailer plug holds three wires, one black, one white, and one green. As I was stripping the 12/3 wire I bought, I noticed it had 4 wires. One black, one white, one red, and one without a jacket, just a plain copper wire. The package said it came with "grounding" or something. Im just not sure what to do with the red or the plain wire. Did I buy the wrong thing? Much thanks.

I noticed the white LEDs have a higher forward voltage. Will this cause problems since the other 2 colors are the same spec-wise?

And also, what type of resistors will I need? Ohms and wattage on them confuses me lol. If there's anything I'm missing please do tell! Eventually I'd like to learn how to make a 1000w LED panel to mount on the inside of my grow tent. This is just to get started I guess haha
