I got the SE ones a few weeks ago. Coming from the 14KK, I thought they were waaaay too blue...until a few days later when they burned in. They're definitely my bulb of choice now. Absolutely gorgeous.

I decided to purchase the 14k and 20k. I looked at them side-by-side and went with the 14k, definitely more white than the 20k. I figured they would give better growth. Plus, I was reading some PAR comparisons and the 14k were much higher. We'll see how they do in the long run!! At $10/bulb I'm definitely excited!!

Do you have pictures? I have been reading around and I stumbled upon this statemen:
"Experiment completed. A number of months ago I posted a question as to the difference between MH HQI 14000K and 20000K bulbs. The feedback from this forum was that the 14 had more PAR and therefor more beneficial for coral. I decided to test that theory and can now, without a doubt, support that opinion. I will spare you a lengthy thread but sufice to say after switching back to the 14000K bulb yesterday I note a definite improvement in the health of my coral. Yes, 1 day later! This after running the 20000K bulb for 6 weeks after running the 14K bulb for the same time period. Although the 20 gives off a superior light to enhance the green pigments the 14 has what my corals need and love."
What do you think? I love the blue tint of 20k, But they say 14k is better for growth... What do you think?

Talon, do you have pictures? Did you get them from 1000bulbs.com?

OK so its been a week with my new 14k plusrites
I like them
at first they seemed a little dim but they have nice pleasing blue and I liek the light amount now
I popped in a 10k XM that had 6 months on it and the center bulb was still clear and man thats a yellow bulb compared to these lol
I guess ill pop back in here in 8 months and see if i still feel the same way

I feel the same about the 14K artemis. They were really dim at first but after a week burn in they brightened up quite a bit - I really like the color now.
My softies that were bleaching under the artemis 10k have got all their color back so I think in general the corals are happier.
A bunch of coraline died off with the light change and I'm still waiting to see a positive response there.
I will update in a few weeks.

10000k bulb should be a more yellow the higher the k value the more blue you get. The more blue you get the less par you get. Then there is a huge difference between par for one type of 10000k opposed to another.
You should always bear in mind that you could lose as much 50% of the par of a bulb going from 10000k to 20000k. There are good exceptions to this where some types of bulb do better at high k values like the radium's that is why they are so popular and people are willing to pay the money. Ok radiums don't have as good a par as a good 10k or 14k but they don't half come close.
Thing is with these bulbs unless you actually take par readings you don't know how bad they are. They could be fantastic for the money or total fail. the actual way they look with the human eye doesn't equate to par readings.

DO NOT plan on them lasting 8 months. Mine lasted about 8 weeks then things started to brown out quickly.

I understand the whole color concept and i understand par is unknown at this point. I just like this color. my 10k xm's in my other tank seemed crisp white but compared to these they seem yellow. i wont run 20k's i dont like my tank that blue and I do enjoy the par out of 10-14k bulbs

Honestly someone should test par on these. This is probably the most important factor. I use Reeflux (20K) SE now and borrowed a par meter off of someone. I used Reef Optics (14k)SE and also a bulb called "Reefmax" (14K)SE from a hydro store and there was a HUGE difference in par almost double between the Reeflux and the Reefmax. All three of those bulbs were on the same ballast and reflectors. I wish I would have used the par meter when I tried the DE plusrite 14k and then switched to Phoenix DE.
Until you know par compared to other bulbs, I don't care how they look or how much they cost. It's not worth it if the par is 50%. JMO
I read through the whole thread as well, that's what lead me to buy them. In my experience, they just did not last. I could have left them in for perhaps a few more weeks, but saw colors were declining.
I purchased 2 250w DE 20,000K Pulseright bulbs.

when ever i switch bulbs i get a slight color shift in corals, in 10 years of MH thats going from ushio's to XM to iwasaki's which were the best. whenever i switch brands that is. with that said you could be %100 rite these bulbs could be weak as all get out but I have a sneaking feeling that if it was the case it would be posted a long time ago that these bulbs should be avoided as they have been out a long time. with the amount sold compared to complaining threads ill have to say these bulbs are holding up thread wise pretty well.
on a side note people pay way to much attention to par, on a sps tank i think the key is keeping the amount and color and par stable. I had 4 year old iwasakis and growth was crazy the whole time, the center of the bulbs were pretty black but yet i have to sell excess corals
No, I don't have any pics. Where my tank is located makes it impossible to get a FTS. I purchased them from 1000bulbs.com. So far I'm happy with the 14k bulbs. Coral seems to love it and the anemones (GBTA and RBTA) definitely love them. The nems look much better now then they did under my 1.5yr old Hamilton 14k.
Here are two more threads worth checking out. Make sure you check out the 2nd link. It has some great pics and even better PAR comparisons of the 400W Plusrites vs. High dollar, brand name bulbs.

My Par Results
My Par Results
I decided to try a pair of 150W DE 14K Plusrite Blubs. My fixture is a 48" Coralife Aqualight Pro. My PAR Results are:
The light fixture is 11" off the tank, and the PAR results are without any top cover on the tank. My tank's dimensions are 36" x 18" x 18". Bulbs have about 16 hours of burn in, and had been running about 2 hours at the time of the testing. My 96W Coralife 420nm PC lighting were also on at the time of testing. So Far, So Good.

Some good info on that second link. Pretty much shows what I thought. I'll stick with name brand bulbs for me since I am setting up a 30" deep tank with clams on the sand and need all the extra par I can get so I don't have to use 400w.
