Need Help on MH ballast

[Andyzr]

Does anyone know anything about a ballast kit made by Holophane corp.?
I have three of these and was thinking of changing out my 175's to these 400's.
Specs are:
Auto transformer ballast, IS-4
Lamp: M59/ H33
Multi tap voltage 120/208/240/277
Amps 4/2.23/2/1.76
Freq. 60hz
Open circuit volts 289
Capacitance 24 MFD/400vac

I have 240v service by my tank and was thinking It might save a few buck running 240v instead of 120v. will the M59 lamp work with a reef system?
I believe it is a probe start.

Way too much information that I am not familiar with.

Would three 400's be too much light? Tank dim are 72" long, 27 high & 18 wide.

Any help would be appreciated.
Thanks,
Andyzr

Any idea's? Anyone?

Sorry I can't answer anything other then the last part:

No I don't think it would be to much light, but unless you have a chiller, it may produce to much heat!

I would ask some electrician friends or even go to GreyBar or is it GrayBar Electric in your area to clarify those technical questions....

By the way Welcome to Reefland!!!

3 - 400W bulbs would be about right for an SPS tank of those dimensions. Here is a link to a chart for bulbs and their ANSI codes and ballast types.

Thanks for the help, If & when I decide to install the 400's I will definatly need a chiller. The 175's kept the tank around 80-81*.


Thanks,

Make sure to explore all of your cooling options before going the chiller route, I know sometime they can't be avoided though. Be sure to look seriously at plenty of fans for the hood and evaporative cooling for the sump if possible.

[Andyzr]

Do you know of a link for the sump evaporative cooling? or DIY project?
Thanks

[Reefland]

No but it's pretty simple really, it's not a piece of equipment or anything. Evaporative cooling is done by using a small fan that blows across the surface of the sump. The water is evaporated a bit faster from the air blowing across it as well as cooled slightly by the cool air. All you would need is a desk fan or similar blowing across the surface of the sump, display or both.

I have a couple of extra cooling fan laying around, this summer I will rig something up.

Thanks

Sorry for not catching this thread, been working to much lately . The cooling fans should do the trick. I run mine about 12 hours a day during the summer. Target makes a great little clip on fan that does it for me!
