    Workhorse 7 Wire Diagram

    A few have asked for drawings of how to wire a workhorse 7 ballast.  Here is a little info I found about them.

    If you want to use two 4' VHO tubes and get full VHO power out of them use the WH7 and wire them in series.. basicly you are foolin the ballast into thinking you have one 8 foot VHO bulb. Here is a drawing to try explain it



    PS. for got to address something people have asked.. if you replace you tar (which is running at full VHO levels) with a WH7 running at HO levels you should get a little less blue.. this also might be hard to notice as the frequence of the electronic ballast also enhances the light which is good for about a 5 to 10% increas in light output in its self.. (also one of Icecaps tricks) so what I would do if I was in your place is try them in series.. if you find it to blue after a couple days then rig them with 2 wires each and see if you like it that way..

    You can find other diagrams and ballast specs from the FulHam Site

    Hope this helps.

    Got more help from another person using these wh7's to power 2x110 watt

    [cut]
    Take all 4 reds coming form the ballast twist them together by hand. Add another length of wire. So all four will be wire nutted together with an extra wire. you will go four reds into one. All the power from the work horse will be going into this one wire. But you have two pins on your VHO so yo have to split that one wire when you get to your first endcap.

    Kevin aka TruePec... is this how you wired your setup?  thanks in advance.

    err looks like both diagrams are wired the same.

    So this an HO electronic ballast then? Not a VHO?

    keep up the good work

    I have wired my workhorse 7 consistant with your wiring diagram except that I have used only three of the four red wires. I have done this based on Fulham's wiring diagram #12 which they recommend be used for a F96 VHO bulb. This is the 8 ft bulb we are trying to emulate when we put 2 4 ft bulbs in series. By using 4 wires, the bulbs may be overdriven but I am no expert. This set up has worked for me for the last six months.

    Are not these ballast built to drive 2 Vhos or just one 8 footer. Will wiring it this way void the warranty.

    Re: Workhorse 7 Wire Diagram

    MINIATUS they are ment to drive one 8 foot bulb. &nbsp;The diagram above shows you how to emulate an 8 foot bulb with two 4 foot bulbs. &nbsp;I have yet to try this but am planning on have these ballasts and bulbs running within the next month. &nbsp;

    Dally and a few other members have been successfull in this setup. &nbsp;others insist on using 2x 3 foot bulbs. 90% of them say to use only 3 of the 4 red wires(what i plan on doing).

    I'm not sure if it voids the warranty. I guess thats a question for Fulham. &nbsp;Hope this helps.

    It's a 50$ ballast, I wouldn't worry about the warranty.. If you don't fry it, or burn the house down.. hehe

    Rob also has 3 of these going on his setup too. Next batch of VHOs I'll add to the hood will use one of these I'm thinkin'.

    Even if you only use one of these ballasts to drive a 6' VHO, it's cheaper to buy 3 of these than one IceCap to do the same thing. Rob's point.. that being said, I have an IceCap.. doh.
