I agree, Sanjay's numbers for the bulb are very good. I recently replaced an old 10K XM with a 175 W Iwasaki 15K. I must say I was a little disappointed with the color of the bulb initially. To me it looked quite green, not the typical blue of a 15K bulb. However, it appears to be burning in to a more white color over the past 10 days or so I've had it running. Certainly a lot brighter. Jury's out for me still.

FWIW, I used to be a die hard 250 W 6500K Iwasaki user until the 10K 250 W XM's came along.

What kind of ballast are you using with it?

I am using the Icecap and it has been bright white since day one.

where can you buy the Iwasaki 175w 15k's
havent found them anywhere yet?

spykes · 09/11/2006, 07:47 AM

anyone got pics of their 175 iwasaki 15K lit tanks?

hello lights carries them.

i use an iwaski 14k 175w and i can grow SPS almost at the bottom of my BB 20gallon high, it turned my orange with green polyp acropa to a light orange i can see white comming through the orange it's either getting bleached a little or it's about to start growing like a mofo i'm pretty sure it's growth seeing as its been at the same spot about 8 inches under the light for 5 months and i noticed a lot better growth with this bulb than my XM 15k.

N_V_S · 09/11/2006, 09:48 AM

Good job!!!!!

I am glad I bought a MH.

accord86 · 09/11/2006, 03:03 PM

Sorry bad pic, but here's my 175w Aqua2 Iwasaki on an Icecap ballast.

I've found the bulbs at these 2 places:

This is a Great thread! Thanks for doing this for us, do you happen to have a Spider reflector laying around that you could slap one of those Iwkia's in? I would like to see how the spider stands up to the Lumanark 2.

Thanks for the great info,
Whiskey

Here is your answer on the reflectors:

Unfortunately I do not. I had one and sold it.

http://coralreefecosystems.com/ has these bulbs for $75.

Oh well. The link that DrBDC gave me a good picture of the difference between the reflectors.

Thanks,

Reading that article, the PFO parallel reflectors are a close runner for reflection. And the price is great on them. They only come in 36" I believe but longer tanks could run 2 of them overlapped and connected. I think that was the first time I saw the white painted inside compared to anything. Kind of blows holes in the white paint theory.

Ya that PFO parallel really beats up on the Spider. I always paint my canopies white, it does make a difference when used with good reflectors, but not a huge one. I have a submersable Lux meter, and I get about 2 or 3% higher numbers with the white paint.

johnanddawn · 09/11/2006, 06:09 PM

i love my iwasaki and i have PFO reflectors as well - can't beat it in a 175W IMO

raynist · 09/11/2006, 08:23 PM

OK, I did some more testing with the Tek Light.

I added an ATI Sun Pro bulb in place of one of the Aquablues and here are the results taken from the same location as the previous test in the first post

Directly under lights at surface, above water

Original Test - 650; w/Sun Pro - 670; With Cleaned Sheild - 667

Directly under lights, just under water level

Original Test - 410; w/Sun Pro - 463; with cleaned sheild - 457

Halfway down tank on rocks

Original Test - 170; w/Sun Pro - 195; with cleaned sheild - 194

Bottom of tank - Barebottom

Original Test - 125; w/Sun Pro - 154; with cleaned sheild - 150

So from these results I would say a cleaned shield has little effect on the amount of light getting to the tank.

Also, the Sun Pro bulb really boosts the PAR.

I took several measurements under each bulb unshielded (1 inch under bulb) for each type of bulb in my fixture, here are the results:

UV Lighting Super Actinic - 424
D&D AquaBlue Plus - 672
D&D AquaBlue - 808
ATI Sun Pro - 885

The tank 'appears' much brighter after the addition of the Sun Pro bulb, but I also cleaned the shield.

Raynist,

Thanks a whole bunch for redoing the test with the clean shield. I just cleaned mine today, and will go ahead and leave it on.

Could you clarify one thing in the statement above. D&D Aquablue Plus vs. D&D Aquablue. I'm pretty sure I use the AB+ bulbs. Do you mean Actinic Plus for the 672 par??

Sorry about that, I always name them wrong.
Here are the correct names and par values

UV Lighting Super Actinic - 424
D&D Actinic Plus - 672
D&D AquaBlue - 808
ATI Sun Pro - 885

The ATI bulb and the UV SA are basically new the other bulbs are about 6 months old.

Here are the results of multiple spots around the tank for the MH and T-5. I noticed that all results are a bit higher than the other day. I think the way I was holding the sensor underwater may have been blocking some of the light.

The T-5's where unshielded.

The MH bulb was not mounted ideally. I used the stand I built for it on the 30g cube and it sits forward a couple of inches from dead center front to back. Side to side it is fine.

The T-5 lights as expected are very consistent in its par values whereas the MH is super intense in the middle and less so on the edges. Keep in mind that I only used one MH bulb and with a second, I would expect some of the values to the far right side to be increased since there would be spillage from the other bulb. The T-5 bulbs light the tank all the way across whereas only one side is lit with the MH.

--Ray

Here are the results: MH numbers on Top, T-5 on bottom

Zoom · 09/12/2006, 05:57 PM

Nice job, It was no doubt in my mine about the MH PAR number to be double of the T5 any way, but i never test it thank you for all the work you done.
