Lighting Website Updates

[alrha]

the website only alows the SE option for them.
If i try the 250W DE i can compare the Coralvue20K to the IceCap 250W DE 20K, seems like the IceCap wins that comparison, I i guess i can assume that the IceCap would win also in a 400W 10K.

Also their 10K bulb seems to perform like a 20K bulb on the charts.

Coralvue also make the 400W DE lamps. These are the same bulbs as the Happy Reefing Bulbs in my tests. I guess Happy reefing is out of business.

Also, I see that PFo lighting also has 400W DE lamps. The KrystalStar, is the name.

Sanjay, thanks for all your work. Do you have plans in the near future for testing "Auqatic Lighting System 400W 12,000k Sunburst" bulbs?

I tested the ALS lamps a long time ago... I know they are not on the web, but they are in one of my articles. Unfortunately this article appeared in a print version.. I have lost my copy of the article to a virus attack a few years ago. My excel spreadsheet with the data is also dead to the same virus attack. I do however have the data in its original format but have not had the time to dig it up and rebuild it. I will get around to it eventually.

Sanjay, do you know how the PFO would compare to the IceCaps? (i didnt see records of the PFO DE bulbs on your site). Seems like that would be my only other option (considering that Happy Reefing is out of business).

[Herbert T. Kornfeld]

I want to know what is up with that new bulb that icecap is marketing as 'aqua blue' besides the usual 10,000K and 20,000K. Whats it supposed to be...an actinic halide or something?

THe PFO DE would be similar to the Coralvue DE. I have that lamp in queue to be tested. But according to David, it is the same lamp as Coralvue

I have not seen or heard of this lamp. Can you provide a link to it. ?

Sanjay, thanks for all of your time and efforts, could you explain what PPFD means ? I am not aware of the meaning?

Thanks Keith

I just recieved my 400 SE XM15k's
love the color but i am awaiting the PAR figures, I doubt they will be good. I also run Icecap elec. ballast.

Keith:

PPFD - Photosynthetic Photon Flux Density
It is basically the count of number of photons falling on a given area (usually 1 meter square) in one second. It is measured in the units of micromoles/m^2/sec. 1 micromole = 10^17 photons.

PAR - photsynthetically available radiation is technically measured as PPFD, hence used interchangeable with PPFD.

OK.. I am done with lighting tests !!!!

Done with the XM 15K test

The results have been sent off to advanced aquarist for publication. It includes results on the complete line of the XM 15K lamps. Hopefully they will have it in the June issue.

Don't bug me for the results - send you emails to the editors there to make sure it appears in the June issue.

[Herbert T. Kornfeld]

when do you anticipate the XM 15,000K bulbs to be added to the spectral plotting page?

On the 'aqua-blue' its mentioned right on Icecap's main page...stating that they have a 10,000K, 20,000K, and this 'aqua-blue'. I have been talking with ASH to get him to even tell me what it is...w/o any real results. I wonder W T F this bulb is suppoerd to be...a 38,000K type like a radium?

how about that Geisemann 14,500K megachrome?

From their main page>>>
"IceCap is proud to announce our new line of Metal Halide DE HQI Lamps. Available in 250 Watt and 400 Watt versions with color temperatures of 10K, 20K and AQUA BLUE. These lamps are made with the highest quality standards and will operate on all electronic (and magnetic) metal halide ballasts."

anyone got any ideas?

Sanjay,

What is your opinion on the EVC 10000K without actinic supplementation? I'm currently running a Phoenix 14K 250w DE on an IceCap, but I want an easy way to get more PAR output, without the heat and extra watts of an HQI magnetic ballast. So I'm considering switching to the EVC 10000K DE. I really don't have the room for actinic supplements in my tank, so I want to run just with the halide.

[Sanjay]

I run all my tank without any actinic suppliments, and I am perfectly happy with it and so are my corals :-)

On my home tank I am running 1X400W EVc 10K, and 2X250W BLV DE lamps in a reef optix III reflector. On the penn state tank we are running 4X400W EVC 10K lamps with lumen arc reflectors.

I yanked out the actincs several years ago and am enjoying the reduction in lamp replacemetn costs and additional electricity costs. The corals are all doing fine and color up nicely.

[Travis]

Sanjay, IIRC you were previously running XM10k's. May I ask why you switched to EVC10k's seeing as how they have less PAR?

[grigsy]

Sanjay - I would like to see testing on several different 175 watt bulb when you have time - Blueline 10K, Hamilton 10K, XM 10K, Coralvue 10K

[trmiv]

Thanks Sanjay. I'm tempted to pick up an EVC 250w 10K for my tank. I like the look of the penn state tank, and there is some italian tank I saw on here that looked great with the EVC 10K.

The PAR is not lower on the EVC running on the Magnetic ballast. The reason for switching out the XM was related to quality issues, we had 2 lamps crack and one switch color on the penn state tank. We had bought them when they first came out. They had some quality problems with glass thickness which seem to have now been fixed. They were kind enough to replace the lamps.

I will get around to these lamps sometime this summer. I need to compile a list of the available lamps and ballasts for these lamps and start acquring the lamps. I do not use 175Ws anywhere and have lost track is what is out there.

Can you make up a complete list of all the 175W lamps and ballast out there ?

sanjay.

[The Grim Reefer]

Sanjay,

If you seriously would like a list of all the lamps and ballasts I have a lot of time on my hands. I could put together a list of all the popular wattage lamps and ballasts I can find on the net. Let me know.

[Herbert T. Kornfeld]

Hey, we need to finish tests / making a list of all the 250watters out there first! Who still uses 175s anyways? Their output is dismal. Most 250watters have double the output of a 175 for just an extra 75watts...

[reefmaint]

Are you ever gonna start testing florecants...???,,,...,,???

What makes you think I am not serious ?

It will take some time to acquire all the lamps and ballast and then burning them in for 100 hr each.

The testing part is relatively shorter.

sanjay.

[The Grim Reefer]

Well what do you want first, 150 or 175 watts? I got plenty of time to do the grunt work of finding what's out there if that gives you more time to buy and test the stuff

[glipper69]

Sanjay,

Anything yet on the XM15K?
