I notice on your site that you list the Giesemann ballast from the Nova fixture as electronic. Giesemann calls it a low loss magnetic ballast. Is it some kind of hybrid? Which ballast does it most closely compare to since there are a lot of bulbs that were not tested with it? Thanks

moonpod · #**552** 06/16/2006, 06:28 PM

They used to have an electronic. It is no longer available.

smatter · #**553** 06/16/2006, 07:26 PM

So the PFO HQI ballast tested would probably be a close match?

moonpod · #**554** 06/16/2006, 08:04 PM

to the electronic or to the magnetic? To the magnetic yes. Essentially for 250w and 150w the M80 and M81 ballasts respectively are very close matches. There is nothing that runs like that G'mann electronic though. It was unique. And it's gone.

To whatever a six year old Giesemann Nova II comes with.

moonpod · #**556** 06/17/2006, 12:06 AM

it could be either one.

smatter · #**557** 06/17/2006, 11:14 AM

That would be cool if it was the electronic, but I'm pretty sure it's the magnetic. It's a 10x5x5 white box and it gets pretty hot.

moonpod · #**558** 06/17/2006, 11:55 AM

If it's heavy and hot, then it's magnetic.

smatter · #**559** 06/17/2006, 11:05 PM

Yep, it's a brick alright.

need some help, sorry for taking a left turn on the conversation but I just got a m81 ballast with my retro and ordered a phoenix 14k bulb for it....can someone point out a link where this comba has been tested ? I would love to see what Im going to get out of this setup! I think that everything I have read shows that the par out of bulbs higher then 10k is pretty low....is this true with phoenix?

wfgworks · #**561** 06/21/2006, 04:37 PM

Phoenix has similar PAR readings compared to the USHIO 10K or the BLV 10K.

tigerarmy40 · #**562** 06/21/2006, 04:46 PM

thansk! that helps alot...now Im a newb when it comes to learning ballast and lighting so what is sheilded and not sheilded? is this refering to glass cover or something to do with the ballast? and if its the ballast how cna I tell?

edit: actually there is some really good stuff in this thread so I am going to go back and read up!!! but if you can help with a direct answer or link that would be great!

hahnmeister · #**563** 06/21/2006, 09:56 PM

you mean the link at the start of the thread?

Shielded and not shielded refers to the glass cover.

DE bulbs need a glass shield to protect from UV damage the bulbs give off.

SE bulbs already have this glass protection built around the bulb, where DE bulbs dont have that shield built around the bulb.

tigerarmy40 · #**565** 06/21/2006, 10:47 PM

thanks guys! I think I know what to expect from my setup however in the phoenix I beleive sanjay only tested the 250! so I can go on that sorta and the ballast was an m80 not m81 and I can count on sheilded....all I needed to know! is there a diference between how the 80 and 81 run bulbs as far as par or energy consumption?

Jovreefer · #**566** 06/23/2006, 09:25 AM

Has there been any testing of 150W 14k DE bulbs? I only see one 14k bulb in these tests.

I'd really like to know about the 14k ushio, phoenix & the 13k giesemann.

I've herd the 14k phoenix is pretty much the same as the ac on the test. Is this true?

zanclus · #**567** 07/06/2006, 06:45 AM

I was wondering if there is info on 400w SE halides. i am running 2- 400w xm 10,000k I also have a xm 20,000k lamp Which I like the color but figure the par is much lower. All lamps are being fired on PFO pulse start ballasts. Thanks

zanclus, the first post in this thread has a link to where you can get lamp and ballast specs. Sanjay has done a pretty thorough job of covering the majority of 400w and 250w bulbs and ballasts on the market. All the info is there. You just need to click the link and put in your lamp and ballst.

smatter · #**569** 07/25/2006, 05:34 PM

Does anyone know when AB changed their 10000K bulbs? I have one that I bought in 2001 and the one I bought the other day looks different. The ceramic ends are different and the light it puts out is a bit bluer. My ballast also makes a little more noise when the new one fires up.

Is the data on the site from the new bulb or the old one? I have the 250W DE version.

timr · #**570** 08/04/2006, 11:33 AM

Is Sanjay's website up and running? I just tried and got a DNS error.

I do not know if and when they changed thier lamps.

I should add the month/year when the lamps were tested... too many things too little time.

hahnmeister · #**572** 08/07/2006, 12:20 AM

I believe they might have changed it as well. I remember AB 10,000Ks (pseudo 13,000K) to be rather yellow... more like XM 10,000Ks than Ushios. I hear from some people now that they are more of a crisp blue and I go 'whaaaaattttt???, are you kidding?'.

wfgworks · #**573** 08/07/2006, 07:01 AM

smatter

Are you talking about DE or SE bulb?

hahnmeister · #**574** 08/07/2006, 01:02 PM

good point. Mine experiences are almost all with DE bulbs BTW...

smatter · #**575** 08/07/2006, 10:07 PM

DE, and I noticed on their site that they have a cheaper bulb called the Oceanlight. I bought it slightly used, it was removed from a new AB fixture. I wonder if I got one of these cheaper bulbs. I bet it is what they include with the fixtures.
