Does NOT include lamp cords, mogal base sockets an bulbs.

Ballast is in good used condition with a few paint chips/scratches. It does power on. I assume its working properly but unfortunately don't have bulbs to tell for sure. 
Makes a slight humming/buzzing sound when on. I believe this is normal for most MH Ballasts. 
It has a date of Nov. 05 on back label. I assume this is the manufacture date. I bought this new but can't recall the date of purchase. It has been kept in dry storage for several years. Ballast was used in aquarium application.

$50.00 (cash only)
Sold As Is. No return accepted and/or refund. 
Item is in Sandy, Oregon 97055 - No shipping!
Serious inquiries only, please.

Great News!!

I found the lamp cords w/mogal sockets. The cords are in ok shape - could use a little cleaning on the prongs.

The Ballast works!!!


I have (2) 400 watt XM bulbs. Not sure the age of the bulbs. Even though they work, they probably should be replaced to get true spectrum and intensity. 


Price is $50.00 (firm) for complete set up: Ballast, Lamp Cords w/Sockets and (2) 400 watt bulbs. This is an incredible deal! 

All items are used. Sold As Is. No return accepted and/or refund.

I received a PM message asking the following questions about my light set up.Thought I'd share just in case others were curious too.


Questions: Could you get me a picture if your light fixture. Do you know if they would work for a duel 175? set up? 


My Response: When you say "light fixture"... are you're referring to reflectors? Unfortunately, I no longer have them. However, one should be able to buy them separately online or a local aquarium store. Most people like to choose their own anyways.  


No, you can't use 175 watt bulbs on a 400 watt ballast. Ballasts and bulbs must be matched by wattage.

Besides if one is paying electricity to run a 400 watt ballast, then it makes sense to use 400 watt bulbs. I doubt there is a huge cost difference between 175 & 400 watt in terms of electricity use. Not sure. I have only ran 250 and 400 watts myself. They were both ran at the same time so don't know if there is a noticeable cost difference.  

I'm sure there are a few folks that would try a different wattage, but I don't recommend doing so. IMO... better to spend a little on bulbs then run the risk of damaging the ballast and or bulbs. Worse yet cause a electrical fire.

This will be the last updated link.  I don't want to annoy everyone with posting new links every time they expire on Craigslist.  :)


Please don't assume the ballast has sold if the Craigslist add is expired. When/If the ballast sells, I will post a "sold" message on this thread.

      Hi guys, just joined the PNWMAS a couple weeks ago. Wish I'd know about this two years ago... Anyway, I have my own kiln/forge and have been making ceramic frag plugs for quite a while now and was thinking about starting to sell them I would probably be selling around 50 or so standard plugs for around 10 ish dollars depending on color and size and such. My main point is that I was curious if anyone would be interested in buying them. I would need to have quite a few people interested or at least a big order being that it costs a lot to run a big kiln and for that price, I wouldn't be making really anything, but I enjoy making them and having a reason to play with mud and fire. So let me know if you'd be interested or not. Also let me know if this is the right place to post this or not haha.
