Sanjay,
Has there been any testing in the Hamilton "TRUE 10K" bulbs?

 

[Sanjay]

I do not know what you mean by the TRUE 10K lamps.. I have tested some Hamilton lamps, they are on the website. In the next installment of data I will have data on the Hamilton 175W lamps.

Thanks a lot for all the work and time invested by you in our hobby
Want to ask if you know who actually made EVC DE bulbs. I mean, if they are built by othepeople (OSRAM, Phillips, etc) or if they have their own factory and where are they built (USA, Germany, etc).

I do not know who makes those lamps. Contact Vince at www.oceanencounter.com and he may tell you, given that he is the one bringing these lamps in.

Awesome site, but I am unable to compare two different bulbs

I will be replacing my 250W AB DE 20kk shortly, its a single bulb setup so no actinics for me, heard good things about the phoenix 14kk and was wondering if this would be a better choice. Ideas or suggestions?

I have been told that the Phoenix bulb is coming from Japan. FWIW

Sanjay,
What instrument can you use to test the age/effectiveness of a halide bulb? I would like to get as much use out of my bulbs as possible and have thought about purchasing something to test them. What would I need and where would I buy it?

The instrument you would need is called a PAR or Quantum meter. A "cheap" one is the Apogee PAR meter and it wil do fine for comparative purposes. It has its flaws, but for what you want to do it will suffice.

Sanjay, I have been using 175W Coralue 14K's with T5 pure actinic supplementation on my 72G bow. I am not happy with visual color and tank seems fairly dim. I will continue to use the T5's but would I be better off with 10K XM's or 10K ushio's for a nice crisp white and good par? Thanks so much for any help. I am using the Aquatinics fixture which sits flush on tank.

Let's look at the 250 watt SE test to compare.
I'm not sure what ballast that is so i'll just use a standard ballast for comparison:

CoralVue 12K 44.18 PPFD
CoralVue 15K 39 PPFD
XM 10k 137 PPFD
Ushio 10k 118.2 PPFD

If your ballast is different it may change these numbers a bit. But you can see that the XM and Ushio will give you much more kick in the PAR and will be a more crisp white light.

where can you buy those 400 watt hqi tawain ballasts?

 

[Sanjay]

I am not sure who is retailing it. I was told that it was being brought in by ALL SEAS (a wholesaler).

Hello Sanjay,

I am in the market for 250w se bulb's..... for the last year an a half i've been running AB 10k's .....but going forward i'd like to see a little more on the blue side.....

Somewhere in the 14k range maybe? with high PAR.

They will be run with the icecap electronic ballast with 1-10k & 1-super actinic VHO as supplements.

What would you suggest?

Thanks AL.

 

[jsc0787]

any numbers for 400 watt se 6500k iwasaki? the 250 watt gives 189 par on pfo, wondering what par a 400 watt would put out.

The data I have for the Iwasaki 400W on standard magnetic ballast had a PPFD of about 205. Those lamps were test way back in 1997 and I lost all that data to a virus, hence it not on the web site. Its in the very first article I wrote.

[Sanjay]

The first set of data on 175W lamps is now available.

Sanjay,
Great site and a lot of useful info. I did not however see any info on the coralvue 400 W DE's. Do you have any numbers on these or any other 400W DE bulbs? I'm going to run 4 of them on a 7' long, 3' deep tank. I have coralvue 400 W HQI electronic ballast to run them with. Just looking for some good bulbs to use. Thanks.

 

[k9asia]

any comparison on 150 and 250 HQIs Im looking at 3 150 or 3 250 14k HQI with VHO actinic but need some recomendation on setup Ie... it will be in a canopy on a 225 72 long x 30deep x 24 high (so should i go with a fixture or pendents or retro im cornfused....
