Was wondering if someone can help me with my lights I want to put up a 400 watt light but am not sure if my closest is deep enough it is 18 in deep ten feet tall and five feet wide I was worried that the light mite be to close to the wall can I put up insulation and ventilation or do i have to scrap my idea and use something else:wall:

Welcome to RIU
for help post a thread in the proper area and not in a thread that isn't related to your problem, that's gonna b your best bet for help.

Also in your info you need to include what reflector your gonna use

if you use say a 6" cool tube you can mount it on the celing and cool it with a inline van and vent it out of your closet to prevent heat build up.

I use 2x 1Kw HPSs and that's how I deal with it.

Check the link in my last post. I don't know much about UV ozone generators so i can't say much on the subject.. i was hoping other people would be able to add to what i'd already collected.

Welcome to RIU
this thread isn't about UV, or ozone generators.

If you would read a bit you would notice that is 2x 1Kw HPSs in 6" cool tubes and a 6 inch inline fan.

all i know is i run a single 1000w hps, and i go 12/12 from seed, i pay $0.88555 for a kilowatt hour (witch is 1000 watts) and i pay about $30 bucks a month just for that, witch isent too bad i guess, but just though i would share.
it is really easy to find out what u will pay, just look at ur electricity bill and see how much u pay for energy, most place i lived varied from 4 cents to 9 cents per KWH.
Hope this helps

its way hard to figure mine
got 2 HPSs and a always changing amount of CFLs

but now that i use a inline fan to suck cold air in from outside rather than my home hvac unit to cool the room my power bill should ok, so far its been below 250 a month and that was my last bill running no HPS and 140+cfls and central AC 24/7 non stop flower room and 24/0 room
at peak use

just in small 26w cfls
390mAx140=54.6Amps (shit i thought it was 40 ish wow i was way over my load limit LOL)
and 8 of those 68w CFLs that were 1.13amps each

HPS is def the way to go
I use both mine at 240 and they use 9amps together

confuessed!!! run a 600 on a dimerbal ballast 8 days on 50% 8 on 75% 6 weeks at 100% a system air intake an out take on tic over an 1 air pump an 1 stone in each tank how much electric!!!!!! help

Welcome to RIU
why would you want to dim your light?
It's like saying I don't want alot of weed out of this plant, that's what your saying and doing.

All you need to do is download the spreadsheet and enter a few bits of info.

How it works

 To calculate your cost per month you will need a copy of your last few power bills, and this spread sheet. If you just want to estimate and know how your power billing works just check out the pic.

First you need to find out how much your power company charges you and how much you allready use. Take your power bills out to do this.
There are three things you will need Total Usage, a Baseline power allotment (this is important as you go over this Base the price per kWh will increase), and the Pricing.

Next find your setup, or enter your own on the Lights sheet.

Lastly enter your info. Start with info from your bills.
Previous Usage cells, enter your Total Usage from your last 3 bills.
Baseline, find and fill in you baseline power allotment.
Pricing, Dont worry if all the entrys arn't on your bill, they usualy increase by $0.05, just fill them ALL in.
Your Lights,enter the number you looked up on the Lights sheet.

On to Version 2. Let me start by adding this post
By using the new Ohm's Law section you will be able to get even more exact with your estimate. I recomend useing this section to get your actual watt usage. As pointed out by babygro and A Good Keen Man useing only bulb comsumption and not power loss in the ballast will throw your results by up to 15%. By useing Ohms Law i think it will be more around 5% Give or Take so I added a range of costs derived from -5% to +5% less or more KWh usage.

98% of electronic equipment will have its Amps posted on it somewhere. As for your voltage just about everyone should know their local voltage but it is usualy posted to.


Refferances:
GCSE Physics: kilowatt-hour <---How to do the math yourself.
Electric Bill Detail - PG&E Bill <---Sample Bill.

Well I hope this is informative and helps you find your right setup for your homes Power Base. To unlock document toke.

So the chart at the very bottom is that the estimated monthly or annual cost?

That's what I run right now.. along with a few CFL bulbs that are used for all my side lighting needs.


I just added the 150watt HPS/MH kit about 2 weeks ago.. just wondering what I should expect to pay for adding the HPS kit.

so, the whole formula thing confused me. im going to be running one 600w hps from a 120v outlet. Distance between these two points is 250ft approx. And power will be run through a 10/2 wiring.

How much would this cost on an average energy bill in America? Thanks.

I'm pretty sure the distance from the electrical source provides negligible loss so you shouldn't count that in your cost estimate. Just use the chart above or find your kilowatt usage then multiply by the number of hours per month you plan on having it on then multiply again by the cost of a kilowatt hour for the area. That is your monthly cost. In the US it varies largely from state to state but about $.15 is average. For a 600W lamp .63 is the kilowatt use if the ballast is 95% efficient or .75 with one 80% efficient. If running for 14 hours a day you sould have the following.

.63 x (14hours x 30days) x $.15 = $39.69
.75 x (14hours x 30days) x $.15 = $47.25

Some places (like where I live) have a pretty good cost as long as your total use is low but the price is doubled or even tripled once you go over a certain amount. For example, my first 100kWh/month cost like $.045 then it doubles every 100kWh. For a cost model like this you have to break out each cost bracket starting from what you use normally (without the lights). Thats why the dude above said look at your electric bill to get an accurate idea of the cost.

good news. my state has one of the lowest cost per kilowatt hour. .10 cents.
And i did calculate it for vegging and it will be 34 dollars a month. not bad. but how would my ballast not be at 100% efficiency? and i NEED to know if i would be losing significant amount of energy/efficiency/or money due to the 250ft of wiring it has to travel to to the light and fans.

what if your bill goes up by lot more like $600 will they come knocking on your door?

LOL.... knock knock knock (open the door, we know you grow in there_


You won't be loosing power through wire. Otherwise Hydro company would lost significant amount of energy on their km's of wireing.
