I don't have a WK7 any more, but like Steve said, if you use only 2 red wires per 48" VHO bulb, they will only work at HO levels.

Since the max the ballast will put out is 220W, 2x48" in series with all 4 red wires, should give you 220W, but I don't know if this would fire up. I have only used 36" bulbs in series, they ran for 1.5 years no problems.

brad did it with the 48" bulbs

Steve

And boy, did they "fire" up alright!! :rolleyes:

Hey Brad,
Was this the cause of the crispy-end-cap-caper?
Steve said he ran 2x VHO X3ft in series with no probs....is there problems with 2X110w 4ft =220w the MAX output of the ballast. I believe Fulham said that 220w was the limit overall and doesn't recomend running continously at this level???? :confused:

Um, not a fair statment, they fired up cuz they were not wired properly.

Steve

Me thinks there is a story in there....

Okay so they'll run VHO 3 foots anyway, maybe 4.. .they'll Underdrive VHO at HO levels.. but, will they OD No Actinics...

Ya know if these do the same thing as an ice cap at such a lower cost.... oh well.. can't complain about a good deal can we.

Doug

I ran 2 36" NO Atinics in series with 2 red wires for 6 months, the other 2 red wires I connecter to a single 36" NO $3 bulb, made the color really nice IMO.

I used the IceCap end caps with no problems. The NO bulbs were way brighter than normal and put off way more heat.

Lee

Okay Lee, thanks that helps out.

Doug

make sure you wire corectly and use both pins for the grounds. here is a couple real quick pics to help.
