Pasific sun Diuna t5 users

[Jerine]

Coming on three months with mine, ran the PS tubes that came with it for 6-8 weeks (cant remember exactly) but dumped them for ATI tubes

Still happy with the light, performing strong, looks great and hasnt missed a beat. Turning tubes on in banks of 2 is awesome compared to other T5 units.

Wait the diuna came with tubes...interesting.

I think it was a deal before Xmas, dont think they have that deal anymore

My new toy up and running! So far very pleased. Just trying to figure out best 10 tubes configuration for SPS

 

[rodneyri]

nice, looks great in black too! keen to see what you think of the light down the track

 

[MSHUR]

Thank you Rodney .
What would you recommend for 10 tubes configuration for SPS?
Remember , 13 years of use Radiums 400w made i big stamp on me)
Still think its the best lighting for SPS)
Your thoughts ?

 

[rodneyri]

What combo did you use in your ATI Hybrid?

I would buy 6 blue+, 6 coral+ and 2 purple bulbs..then you can play with a combo to get what you like and have spares for the next change over.

Start with 5 blue, 4 white and a purple and go from there.

 

[MSHUR]

In ATI Hybrid i use 4 B+ and 4 C+.

here is my start:
front-back:

Giesemann Actinic Blue
G True Actnic ( will be change to FM Royal Blue )
ATI C+
ATI B+
G Aqua Blue
KZ FP
G Actinic Blue
G Aqua Blue
G True Actnic ( will be change to FM Royal Blue )
ATI C+

Bulbs 2 and 9 is one channel that i run for 10 hours. I am waiting for FM bulbs to try, a lot of people swears by that bulb so meanwhile i have G true actinic
Also, contemplating either to get LED strips my sides or not. I was thinking to order from BuildmyLEDs.com and order mix spectrum of 405, 420 and 450 nm and control them via Profilux on 1-10v.

What you think?

 

[JaySchulz]

Any updates on anyone using this fixture? Would love to see more pictures.

 

[rodneyri]

Still going strong

Dug up and old pic when using the ATI Hybrid to see the PAR difference. Measurements taken with the same PAR meter, same light height (22cm above water) and same bulb combo. The new tank water level is 3cm shallower (first pic)

Pac Sun Diuna 8x80w

ATI LED Hybrid 8x54w - Numbers in brackets are the T5 only no LED

Are these fixtures dimmable?

 

[Przemek_PacSun]

No, this fixtures are not dimmable. 4 years ago we manufactured dimmable lamps but we stopped and decided to go in another direction.
Instead of using 2ch dimmable(2+6 like in ATI for example) we offer possibility to switch on/off each pair of T5 tubes separatelly. It allow Customer for simply "dimming" lamp like 25%, 50%, 75% and 100% without terribly decreasing of T5 tubes lifetime (when they are used with dimmable ballast their lifetime can be shortened even up to 30%).

I just bought the 48" version of this light for my 100 gallon aquarium that's not setup yet. I decided to go all T5 because they just work and are literally plug and play. I like the even diffused lighting and coloration, and I don't really care about shimmer that LEDs can provide even though it's nice to look at. The downside is bulb replacement costs over time, but I'm ok with it. I like the software and Bluetooth connectivity. They're supposed to be coming out with a major update next month, so hopefully they'll have some neat features and increased stability. I'm going to put a pair of brand new Radion gen 2s up for sale to help cover the cost very soon.

I will be joining the club when my new Pacific Sun Diuna 10x54w arrives sometime next week! Still working on bulb combos. Much like MSHUR, I am coming from 400w Radiums on PFO HQI ballasts and 2 x Blue+ and 2 x Giesemann Pure Actinic. Below are the bulb combos I posted in the T5 thread, but I am curious about opinions here. Please let me know your thoughts and experiences. Anyone have any updated pics with the Diuna?

1 other quick note. I currently have 4 54w T5s on my light rack in retro kits. I measured between the farthest outside pair and it is just over 25.5 inches. So I think I have just enough room to sneak the Diuna between them and I could use the outside retros for Actinic supplementation or otherwise. They are on the very edges of the tank, and they have actinics in them today and could be useful for nighttime viewing if nothing else...

Thanks!

Combo 1:

Coral+
Blue+
Fiji Purple
Blue+
Giesemann Tropic (I am assuming this is the same bulb as their old Midday)

[MSHUR]

i would do combo 3

 

[JaySchulz]

How's the software working for everyone with this light. The biggest complaint I see about the Pac Sun lights is the software is glitchy.

Yep id go the same option too.

I appreciate your feedback Rodney. What's your thoughts on the Diuna vs a sunpower.

 

[dcmartinpc]

I know you asked Rodney But... From all the research I have done, the Diuna is on par with or potentially even slightly better than a ATI Powermodule. It's in a different class compared to the Sunpower.

But that's just anecdotal research on my side. Rodney did post some pics earlier in this thread comparing a Powermodule to the Diuna and the numbers were very close with the same bulb combo.
