13w Ballast Wiring


freeqgOd

Recommended Posts

I am in the process of up grading my lighting. I had looked at this post when it was first posted but it wasn't until now that I had enough extra money to upgrade.

 

I have everything wired up and working great. It even looks pretty good. The only thing is that the ballasts buzz when they are on. Is there a way of stopping the buzzing or is it just the nature of these ballasts? I have three and two out of the three buzz. One of them is an out right hum. Any ideas?

 

I am going to put them over my 2.5, Two 10000K and one actinic.

4 of them over a 2.5 sound good? Im thinking 3 10k's and 1 actinic

I did 4x13w over a 2.5g AGA Mini-bow. It was, in my opion, brighter than a 96w powerquad over a 10g. I did 50/50 10K/Actinic, but 3x10K w/ 1 Actinic should work too. Anyway, a fan moving lots of air is a MUST with that much light packed in such a tiny space. I used a 40x40x20mm fan run at 9V, which worked well.

THey run hot so make them external. I am glad someone FINALY read a post of mine form a while ago and made use of this EASY and cheap DYI lighting option. I hated the fact that hellolights.com was raping people on their balast bulb cobos.

Glad to help...

 

By the way...saw mention of a molex connector for the 13w diy setup...I'm in the process of building a 10g w/diy stand, canopy, sump. Having trouble finding bulb sockets.

 

Anyone got any info on these molex connectors, and where to get them/what to ask for.

 

Thanks in advance for any help.

If I'm not mistaken, I believe molex connectiors are the ones coming off a computer power supply for powering hard drives, CD/DVD drives, etc. Mayhap you have a spare, or a used computer store near you has one in the dumpster out back that you can harvest...

Guess I'm just Sssthoopid...how exactly will a computer power supply conx hook up to a 13w bulb...

 

Not trying to be an jerk...just confused...

I would say the growth was good to moderate with the 6x13w. What was particularly useful with this configuration was the ability to stagger the lighting cycles.

Yup, you could safely hook a whole lotta 13w ballasts to one cord. If your cord is rated for 15A, you could theoretically connect 1800w worth of stuff to it. Not that I would advise it!

 

Anyway, just make sure you have a wire nut that's big enough to hold everything securely together. Ensure you have a sturdy physical connection when you join the wires, not just an electrical one.

HD only has the ballasts that takes 20watts....is that too much for a 13W pc? Are those ballast magnetic or electronic?

 

-Correct me if I'm wrong....for WIRING: just connect the positive wire from the plug to the positive side of the ballast. Then the other wire from the ballast goes to one end of the GX-23 bulb. The negative wire from the plug goes straight to the other end of the bulb?

So far my setup is fine with the 20 w ballasts. It has three wired together into one outlet. I used the cord from a power strip. It was the cheapest way to go at around $3 it was much cheaper than getting an extension cord and cutting one end off. I'll post a pic once I can get my hands on a digi camera.

 

As has been mentioned dead power supplies are a great source of free molex connectors. The case also makes a great place to mount the ballasts and each one has a fan that can be used for cooling. I'd just go to a comp repair place chances are they will have some dead power supplies that they can give you. You won't have to do any dumpster diving.
