10k vs. 20k Experiment (Pics)

**MtnDewMan** · 10-19-2002 01:06 AM

Okay, I have a Radium 20000k bulb that I have been wanting to try out just to see what it looks like in the tank. Definately much bluer than the 10000k I have running. Here is what I did.

Both pictures were taken with no flash and minimal ambient lighting.

The first picture (taken on 10/14/02) consists of one 250W AB 10000k double ended bulb on the left and one 250W AB 10000 single ended bulb on the right, both driven off a dual PFO HQI ballast. 330W of VHO Actinics are also on.

The second picture (taken on 10/18/02) consists of one 250W AB 10000k double ended bulb on the left and one 250W Radium 20000k single ended bulb on the right, both driven off a dual PFO HQI ballast. 330W of VHO Actinics are also on. Note the Radium was the first time running, so there has been no breakin period.

Notice a difference?

**Reefland** · 10-19-2002 01:14 AM

Wow, that is blue! How does it look without the actinic on?

We are going to run our 75 with just the 250w AB DE bulbs and no actinic. I really like the color of just the DE bulb. In your picture, the coloration of the tank overall looks just like ours with only the MH. What is your opinion on running without the actinic? If you ever get a chance, snap a shot with only your AB DE bulb, no actinics for a side by side comparison.

Regards,
Scott Z.

The 20000k side was definately on the blue side. I pulled it and replaced it as I am out of town for a day or two. I will reinstall it at a near future date while I am home more. Maybe I will run it on the right side for a week or so to let it break in and then take the picture over also without the actinics.

I will take the two 10000k without actinics, then the 10000k on the left and 20000k on the right with actinics and then that configuration without actinics to run the full configuration.

All I need is time

**Reefland** · 10-19-2002 01:50 AM

Thanks Chuck!

I wanted a white coloration with just a hint of blue and the 10k AB DE'ed gives it to me so I am not going to go with Actinic. I am just curious to see what your tank looks like without the actinic to see if the coloration is that close or if it is the camera.

The type of ballast also plays a role, what kind are you running?

Boy I have got to stop making those late night posts!

What is the likely hood of the PFO ballast and the SLS Bluewave buring the bulbs different colors?

**MtnDewMan** · 10-20-2002 03:24 PM

I think I have decided to not mess with success so I am going to keep the 10000k bulbs in. I will however snap a couple of more pictures for everyone. One with just the 10000k bulbs without actinics and the other with one 10000k bulb on the left and a 20000k bulb on the right without the actinics on. That will run the whole gammit of configurations even if the 20000k isn't broken in.

**MtnDewMan** · 10-20-2002 10:55 PM

As promised, here are pictures (all taken on 10/20/02) in the same conditions, same camera settings, no flash :

Here is one again with 10000k DE on the left, 10000k SE on the right with actinics taken tonight.

Here are the two 10000k bulbs without actinics

Here is the 20000k radium on the right side (just the bulb on the right is on) with no actinics

And last, here is the 10000k DE on the left and the 20000k SE on the right with no actinics

**stang69** · 10-20-2002 11:16 PM

I Like the 10 k with atenics but maybe its just a pref thing but IMO just looks better and more highly colored. Great lopoking Tank By the way. Congrats on your tank of the month too.

**stephane** · 10-24-2002 11:34 PM

Wath ballat did you use ? If you use MH ballast you should try an HQI or an electronic ballast the result will be much more different this bulb
look to blue and to dim on regular MH halide balast but awsome white with only a small tint of blue on the right HQI

**MtnDewMan** · 10-25-2002 12:35 AM

Thanks Stang69

Stephane ... as stated in the original post, I am running a PFO Dual HQI ballast.

**stephane** · 10-25-2002 01:04 AM

Sorry I was on the impression you here using 400 watt Radium but just found in fact it was the 250

I have to agree it's not the first time I heard people said that they are to blue

***Papa Doug*** · 10-25-2002 09:24 AM

HI Stephane,
Nice to see you here.

**Ninong** · 10-25-2002 09:38 AM

Bonjour stephane, bienvenue � Reefland.

**stephane** · 10-26-2002 03:42 PM

Tank Doug! I was memeber here long time ago but my registration was no more active, since now I dont go to much on the west I have a bit more time and drop here surfing the net

Tanks ninong! je voie que tu parle fran�ais! ou bien tu a tricher avec un traducteur

I tink there some french part in Louisiane ? Is it the Acadian peolpe or Im rong?

**Ninong** · 10-26-2002 04:21 PM

Stephane,

I speak some French because my grandparents and all of my cousins were fluent in it. My great-grandparents came from Normandie. Unfortunately, my mother was not fluent in French because she was raised in the city as opposed to all of her cousins who were raised in the country. My great-grandparents spoke only French.

Louisiana was originally a French colony, which is why it is named after King Louis XIV and his wife, Queen Anna. The City of New Orleans was named Nouvelle Orleans (New Orleans) in honor of Philippe II, Duc d'Orleans, the regent of France under King Louis XV.

We have parishes instead of counties and our state laws are based on Napoleonic Code instead of English Common Law. The local cathedral is the Basilica of St. Louis, King of France. Next to it is a building called the Cabildo, where 199 years ago agents of Napoleon sold all of the Louisiana Territory to the United States for $15 million. Jefferson really wanted just the port of New Orleans for $3 million but Napoleon decided he wanted out of the New World and needed funds for the military at the time. So the United States doubled in size for a mere $15 million. And there were those who called for the impeachment of the President at the time for squandering such a large sum of money on a wilderness.

Because Louisiana was already a French speaking colony, French speaking people from Canada migrated here to avoid "problems" with English speaking Canadians. Sound familiar? Anyway, French Acadians began to arrive in New Orleans in 1755, 37 years after its founding. Then in 1763 New Orleans was taken over by the Bourbons of Spain and remained Spanish until 1803, when we became French again just long enough for Napoleon I to sell us to the U.S.

When I was a young child, all of the elevator operators in the department stores called out the wares on the various floors in both English and French. And if you want to go back more than 100 years, all schooling in Louisiana was in both French and English.

The large green highway signs that welcome you as you enter the State of Louisiana read: Welcome to Louisiana and Bienvenue � Louisiane.

**Poseidon** · 11-03-2002 05:50 PM

Well this post sealed it.... I was trying to figure which bulbs I should use and 10,000k with actinic is exactly what I'm looking for !!!

Thanks, Mike

**MtnDewMan** · 11-03-2002 07:30 PM

Cool ... glad the pictures were able to help you out. I like that setup for sure

**Mangrove** · 11-07-2002 12:58 PM

Speaking of helping out, it has helped me too. Gonna get some 250w 10k AB mh's...who has the best price on these? Thanks

**sunflashx** · 12-24-2002 05:56 PM

What is the significance of the bulb being Single Ended or Double Ended?

Why did you choose to have one of each?
