KZ Lamps, Second test

[The Grim Reefer]

Well I got the 54 watt lamps in to test and I was right to be skeptical.

The PAR for the Fiji Purple is about 10% lower than a ATI Aquablue, The Fiji is a nice lamp though. I plan to use one.

The Coral light had the same PAR as a ATI Aquablue. The light it produces looks the same, the physical apearance of the lamp is the same, the burn pattern is the same. If I were a betting man I would put the house on these being the same lamp. If the Coral Light does have 5% red it doesn't show.

I will do lamp pics tonight and start a new thread.

Where did you get them from? I am going to try the purple bulbs...

What other bulb would you compare the purples to spectrum wise?

[The Grim Reefer]

I got the last 2 purples SPS gardens had. Captive Oceans was supposed to be getting more in any time. They are listed with the Zeovit stuff there.

Nothing Ive seen compares to the purple.

When I saw the test numbers, I think it worth to buy ATI and UVL bulbs because cheaper and has good numbers but KZ bulbs are too expensive plus shipping and same principle of ATI bubs

Maybe Grim thinks that best bet to buy ATI and UVL than to buy lots of KZ.

Price of ATI and UVL to KZ bulbs = you save about 20 prcents if you buy ATI and UVL?

tell me if I am wrong about product of quality than import bulbs?

I talked to the guys at captive oceans and their fiji's are at customs where i'm at and are going to be shipped any day now. They should have them any day now, but said it would be the end of this week.

Grim, How do you think this would look. 10k 250 ushio with reefstar, with 4x48" Overdriven t5's 2x blue plus and 2x purple fiji's. THis is what i'm going to do anyhow. I'll keep the sps in the center and the softies and lps, near the edges of center on out. I'm hoping for a very unique look.

So what kind of par are we talking about for the fiji's?

[The Grim Reefer]

The purple is a different lamp. It;s possible it will not have a great effect running with a Aquasun or other lamp with red spectum in it but I am going to try it.

[luke33]

Oh yea, my tank is a 125g 6', sorry, i'll post some pics of the lighting when its all ready

The Fijis have about 10% less than Aquablue. Should leave them about the same or a little better than blue plus.

[luke33]

Thanks Grim, well imo, they are more expensive yes, but there quality bulb's and there's nothing out there that will compare to the color you get with them. So a B+ in my book.

Grim,
Have you tested the Aquascience 15K?

[The Grim Reefer]

Yeah, it has a little less PAR than a Aquablue

[Tagareef]

Grim,

What does this test tell us about the validity of the tests done with the 39 watt KZ bulbs? Is it still safe to say that the 39 watt KZ bulbs are superior to others at this wattage?

It tells me I should buy a 39 watt Aquablue lamp to test but I just can't justify buying a lamp I will never use. I have another lamp I will try checking against them.

Grim,

I ask you something, just base on your opnion. Which is one that you are relabile on it, feel more comfortable with the produce of bulbs,

ATI or KZ bulbs..

Right now I am in stuck between two.

[HBtank]

Would you still use an actinic bulb with the fiji purple Grim? I think I might just use blue plus', aquasun, aquablue and the purples and see what it looks like.

[iantoh]

Hi there grim!

thank you so much for taking the trouble to conduct these tests- they add greatly to our understanding of the T5 tubes available to us.

i was wondering though, as the KZ Fiji Purple Tube is an actinic tube, as opposed to a daylight tube like the ATi Aquable Spezials, isnt' comparing their PAR figures an imbalance of subjects?
Additionally, in your experience with the Fiji Purple tubes, do you think they are likely to fuel greater algae growth as compared to other tubes because there's more red spectrums?


I've seen the Purples in action before, but personally, im still presently running 2 x KZ Coral Light and 2 x ATi Blue Plus tubes right now, in 4 x 39w fixture over a 70Litres display tank, and would like to know what you think of me swopping one of the Blue Pluses out for a Purple.

THank you!

Hi Grim

many thanks for the info. Its good to hear that the FP's still produce a decent intensity and I'll keep the current 4/12 slots for the purples. IT worth noting that the SPS tissue begins to shift over time in response to the spectrum.

My main interest is a comparison in intensity between the KZ Coral Lights and Aquacience Specials - have you been able to compare the two?

Many thanks

Hi Ian

Only if there are the nutrients in the water or rocks to feed alage growth. If you have ultra low nutrients, red/pink spectrum light isnt a problem IME

I will fire them up side by side and do some tests and pics.

Hey, I just fired these up for the first time. Your gonna have to go on what people who have used them for a while have to say. I think the purple is sorta a hybrid lamp, kinda like a aquablue with more actinic properties perhaps. I gt to fire it up in a single lamp rig to see what it does stand alone but in combination with a UVL super actinic both appear to add something to the look in their own right.

The Fiji Purple is a one of a kind lamp. No difference between a Aquablue and a KZ coral light as far as I can see. There is no way in hell I would spend an extra 10 bux for a Coral Light.

Hi Grim,

Thing is, i went out and did just that about a month or two ago. i changed out 2 x ATi Aquablue Spezials for 2 x KZ Coral Lights, and within a few days, the purple tips on my A. Gemmifera colony returned, when it was mostly a greyish body shade under the ATi Aquablue Spezials. I understand that might be too anecdotal an account to sway your judgment, but even though to my eye, these two tubes look the same, i have to say that it has resulted in a slight difference in the colours of my corals.

I'm gonna try to dig up some old pictures to see if i can show you the difference.

cheers,
ian

[The Grim Reefer]

How long had you been running the aquablues? I have been told the lamps have a signifigent color shift within 6 months and the euro guys are changing T5's at 8 to 9 months. Could be the spectrum shift is comming into play much sooner than we were led to believe.

[iantoh]

Hi grim,

Prior to switching the 2 aquablues to coral lights, i had ran the aquablues on my system for the past year and a half, but at the point when i decided to make the switch, that pair of aquablues were only 3 months old, so its leading me to think its not spectrum shift, as i've had this A. Gemmifera colony for almost 3+ years now, and its not shown its purple tip throughout that whole time, other than for the initial first week or so after i first bought it long ago.

i'm still experimenting though, and its good to hear from more reefers about their own experiences. Since you've already purchased the Coral Lights, perhaps you could try them out and see if any change occurs too?

chhers! :P

I personally dont use 50/50 lamps at all. I prefer using blues, actinics and daylights to get the mix of light I like. Just looking at the Coral Light and the Aquablue I seriously think they are the same lamps. I have a cheap Spectrometer and I can't spot any differences looking through that either. It's just a 30 dollar hand held deal but it does provide a better look than the naked eye.
