Workhorse Ballasts

[Achilles]

Can someone fill me in about these ballasts. I have heard that they are electronic and that I could run 4x55watt PC's over my refugium. Are these ballasts any good? Who's using them?

It is my understanding that Albright lighting sells them, anyone know for how much?

They sound too good to be true! Ice Cap ballasts are just too much, and I am not happy with the 2x30watt GloMat system I have on there right now (50 gallon refugium).

Thank you,

Hi Jeff,

It really depends on the brand of PC bulbs. For instances, it takes a workhorse 7 ballast to drive 2 55W panasonic PC's while 2 55W Sylvania PC's can be drive from a workhorse 5. For the past 3 months, I've been using a workhorse 7 to drive a 24" 20W 6700K t12 as well as 24" 20W t8 marine glo lamps at 110W each. They are bright!!!
You can use these ballasts to drive different lamps in different config. Check out Fulham's website
Disclaimer: The above mentioned lamps are overdriven. I am not liable for anything that happens if you attempt the same

How does the ballast overdrive the lamps? and how does it do it to that degree... that quite frankly is amazing!

I just phoned and he had 96watt pc's also.

Do you think the workhorse 7 could drive 2x96watt pc's over my refugium at 100%? It should given that the ballast has a max wattage of 220.

Thanks!

The best person to talk to is "Reef Burnaby". He was the one that provided this thread http://www.reefcentral.com/vbulletin...threadid=48133it explains over driving no's. Although in it, a different ballast is used, the workhorse will work just as well. As to the 96W pc's you mentioned, I assume that "they" you meant Albrite? J&L lowered the prices on their 96W pc's to $60 each. I am planning in the near future to build a new canopy and use a workhorse 7 drive dual 96W pc's for my 33G

A ballast overdrives a lamp by passing a higher current through it than initially intended. When you hook up multiple wires going into a tube you are sending current that was intended for multiple bulbs into one. That is in very basic terms..

If you know parallel/series circuits in effect you are taking the current in multiple parallel branches and combining them into one wire. The voltage being sent stays the same as it is in parallel but the currents are added together.

A workhorse 7 will work fine for two 96W PC's

That help?

How much are the 10,000K 96W PC's at Albrite?
I talked to this guy who imports them in and he said that he should be able to get them in for $55 including tax. I think he said they were Custom Coral Life.

Hi,

Like Darren said, it is basically driving a lamp beyond its normal intended operation. Are you familiar with Icecap 440 or 660 ? Basically, the workhorse is a poor man's Icecap -- that was the main idea. It does not have as many features as Icecap, but it gets you 80% of the way there. Stuff like dimming and soft light starting are not on the poor man's version.

With everything said (and I REALLY appreciate the input), it sounds like this "poor man's version" is exactly what I should use to light my refugium. Those extra features are not really needed on the refugium anyway.

Another few question though,

1. Does overdriving cut the bulb life down?
2. What is the worst case scenario from doing that.... a burnt out bulb or a burnt out house!?

Thanks!
