Thank you Fiji blue for letting me use the par meter and the prism thing that I am still not sure how to read.

First thing I noticed is lumenarc's, well hate to say, but they SUCK. (based on initial par readings

So first thing i did was change out the lumenarc and put my other lumenbright in.

Originally the lights were around 16" up and noticed my par was not the best so I lowered the lights so the glass was about 3" off of the water

All measurements are as close to center of tank as i can get on front to back.
Because I do have an acrylic tank with euro bracing there is a loss in certain areas that wouldn't be with a standard glass tank this being said here are my numbers

all numbers are from water level down roughly ( I did not break out a ruler)

Left Light
1'' 1100 par
8'' 830 par
12'' 550 par
Top of sand bed 250
to the left by my meteor shower 200 par
to the right center by my blue/green ( Bad *** acro) 360 par

Right light
1'' 1000 par
8'' 830 par
15'' 530
Top of sand bed 300 par
to the right but center 200 par
to the left but center 400 par

When lights were at 14'' height
1'' under 760 par
12'' under 370 par
sand bed 200 par

the prism meter he gave me

showed all the colors from red to purple 650-420

When i used the same instrument to look at the radiums they only went to the blue band around 500.

One thing I can say is my corals in just the couple days have really colored up compared to before. One frag that well pretty much turned brown in my tank but in store was awesome red and orange acro, I noticed is getting its orange back. my red planet is getting its green back also.

This is still a wait and see how they will last long term, but for now they are great and finally a bulb for us 250 De reefers.

If anyone would like to see these lights you can email me at jfuka78@gmail.com
 
I recently went from T5 to MH and I'm using the Phoenix 14k (250DE) Have you ever used these bulbs and if so, how do you think they compare to these Neuco's? I'm no where near an expert on MH's but everyone seemed to recommend the Phoenix 14k's for DE pendants.
 
20k, I was running phoenix before, first impressions I prefer the nueco. Longterm time will tell. I am definately no expert.
 
How do you use the prism? I mean I know how a prism works but how would you get a beam of light to read? I really want to try this with my setup. I wonder how reliable this method?

Look at my thread build for a PAR photo with the phenoix. I was not a fan of it. Color was washed out and spectrum shifted fast. I'm using EVC now. I need to gt a par meter to measure it.
 
From what I understand it can show the spectrum of bulb you are using. It is pretty cool. Fiji blue may be able to explain this better. I know when I looked at a radium it did not show the purple spectrum (420) where this bulb does have that spectrum and can be seen with this viewer.
 
I asked about evc bulbs but they said nobody has them because there were issues with consistency with them. I was planning on getting them. I am hoping these new bulbs do not shift.
 
They will shift. It's just a matter as when.

So far I'm loving (and so are my corals) the evc. Much better color spectrum, good par, my corals have grown and colored up better with evc then the phenoix.

How long before I can expect the Phoenix bulbs to shift color? Also, does that mean its time to replace the bulbs?
 
Not time to swap ouy, more of this means the bulb has broken in and that will be your spectrum.

Not true. You are referring to the bulb "break in time" which is about 2 weeks of burn time that after that the initial bulb brightness would have settled into its adverised kalvin. When your spectrum shifts it IS time to change your bulb. It will mean a break down in the blue spectrum and make our aquariums looks less appealing. The increase in green/red/yellow spectrum will cause in nuisance algea growth.

Mine lasted 6 months before spectral shift. Wasn't that happy. Granted its a bulb that costs 1/2 the price as others, but others last about a year, so there is no benefit.

Yes, when spectrum shifts it's time to replace. Mine turned into a washed out white with barely any blue.
