Good to know thank you for your very fast reply +rep
unfortunately, probably not. unless your able to find an adapter that fits the cord type of your pc fan, however thats an expensive part to buy when you can safely modify any plug in 12v adapter that has enough amperage/wattage to push the fan.
typically 12v plug in adapters have 2 conductors. when performing this type of mod i like to use the cheap generic universal adapters you can find at any electronics shop. i like them because the polarity is usually marked on the cable, and if i mess it up, its cheap! just get another one.
cut the cord connecter off the pc fan. theres typically 3 wires, a red, a black, and a yellow/green/odd color. all you need to worry about is the red and black. the other wire is an rpm monitor for the pc fan. it has no purpose here. the red wire is the 12v+ the black wire is the 12v -
on the cord adapter, the wire with the white strip is normally the hot (+) and the unmarked wire is typically the common (-), although i have run accross a few where the exact opposite is true, so check it with a meter if you have one.
just connect the marked (+) wire to the red and the unmarked (-) wire to the black. i like to use ideal small blue wire nuts for the connection, although ' beanie' or 'dolphin' or 'beans' type telecom compression connectors also work well
puff puff passes it backanytime. im here to help
how long is the wire?
thats the only thing that would affect the voltage... if it was longer than 300-350' you might have problems.
you should be good for 3840 watts
sounds like a loose connection behind the switch.oh yeah i forgot one of the switches stopped working to
the lamps wont ignite without some modifications..... you really have to have a cap for each lamp, and have those caps being fed in parallel with the ballast. the cap must be for the lamp size, not the ballast.. so if you had a 1000w probe start MH ballast, you would need 4 capacitors for a 250w ballast with the same ansi code.I've read from a few sources about running a lower wattage bulb, meaning a 400w bulb in a 600w ballast, without much adverse effects other then possible lower bulb life.
My question then is, would it be similar to me running two lower watt bulbs off one ballast, say two 250w bulbs in a 600w ballast. Thoughts?
someone else already has a simple, great DIY for cfl fixtures, check it out, no wiring required!i am currently making my own growbox, and i am using ( hopefully ) multiple cfl's. I am young and dont know much at all about electrical questions. i am always seeing a multi unit cfl system ( one fixture holding like 4 or 6 bulbs) ...
A.) is this easy/safe enough to do?
B.) can u buy these anywhere, and i would still need help hooking it up.
thaaank you so much i look forward to hearing back from u
I saw a number of grows using these power strip CFL fixture for VERY successful micro and slightly larger personal use grows. One of the usually less than mentioned bonuses of these power strip fixtures is you can customize like crazy!! (if you're a DIY nut like myself, that means fun) Say a lone branch started growing towards a light... no big deal, hop over a socket in the fixture. Got a dark corner? Put a higher wattage CFL in the socket nearest. Just a lot of options, and i like that.
So all in all, they seem pretty cool and I am in need of a light solution for my AG cabinet (link in sig). So off I went to pick up some bits and pieces to get a pair of these knocked out!
First let me introduce you to your new best friends...
The setup I'm going with is more targeted at flowering, hence the big 2700k bulbs and the smaller 6500k.
I'm using both, because from research I discovered that with CFL you want a slightly bigger spectrum than with HID. Something about the efficiency of the bulbs and the way the light dissipates and this and that... not the point we're building a fixture. Just my two cents, if you're going to do a Vegetative lighting rig, go with bigger 6500k and maybe no 2700k at all... I veg'd CFL with only the 6500k and did just fine!
Moving right along...
these are a bit of a pain to find, so a heads up, skip the home improvement retailers and head straight to Wal-Mart haha. I hate to promote the evil beast, but dammit they had the shit I needed!!!
So pretty simple from here, plug in the adapters, screw in the bulbs, hook up to your timer! That's all... hope this gives some anxious to get going growers some ideas beyond expensive HID lighting. It's cheaper than you think to get started!

Yeah I'm def going to take your advice with the relay, if youcould still give me a diagram that would be great. Remember I'm not an electrician, so try and keep it simple, thanks for all the help.one timer, and a single pole, double throw relay (formC) timer throws the relay, which would kick on the 200cfm, when timer shuts off, relay closes and activates CVC...
if you need a diagram let me know.
relay would be cheaper than another timer, hands down..... simpler as well.
