It seems only the DE version has been tested. I also await the 14,500K megachrome 250wattDE.

can you point me in the wright direction please

I have the full collection of the latest Giesmann Lamps and they are currently being burned in.. and hopefully tested sometime early next year.

Burning lamps is my biggest bottleneck. I can only burn in 2 at a time, and at 100 hrs of burning time... the days quickly add up. I have about 15 lamps waiting to burnin.. so that is almost a month or more of just burn in time, if I burn in the lamps all the time - which I do not.

Some day I'll get there with the data you are looking for.

Thanks

I typically wait about 6-8 weeks after the data has appeared in the online magazine before posting any data on the web.

Sanjay you can send a few lamps to me i will help you burn them in

Herbert T. Kornfeld · #**331** 12/18/2005, 11:37 PM

yeah, me too!!! I have icecaps, PFO HQIs, in 70watt, 150watt, and 400watt versions that could be used for burning in bulbs if they had to...lol.

Denadai · #**332** 12/31/2005, 03:23 PM

Sanjay,

IÂ´m from Brazil, and you test for us the Venture 6500k....Thank you very much !!!!!!!!!

I have a doubt....in your opinion, what is the best SE 400W 10K bulb ? XM or USHIO ?

And 250W SE 10k Bulb ? XM or USHIO ?

IÂ´m setting up a new 160G and IÂ´m in doubt what kind of bulb should I go. The reef will be a only SPS

ThankÂ´s

Roberto

Herbert T. Kornfeld · #**333** 12/31/2005, 04:42 PM

Quick Question...are Ushio and BLV the same? I thought they were but I had a friend that had Ushios and swapped them out for BLVs that he said are much bluer and nicer.

moonpod · #**334** 01/02/2006, 11:04 PM

Herbert it depends on which bulb you are talking about. The new 14ks are the same. The older 10ks and 20ks are different. Sanjay has tested the 10ks already and the BLVs are typically 1-2k higher. ie the Ushio 250w 10k DE test between 10-11k and the BLV 12kish.

Roberto, Sanjay didn't answer you, but to the best of my knowledge he's using the
EVC 10k which is surprisingly white for it's testing color temp of 8k.

HTK-

We discussed this a bit in this thread a little while back as well.

From IceCap:
Re: Iwasaki 175W Aqua2 14000K Mogul Base bulbs.

We have a case coming in this week. Four are going over a local tank and I'll get some pictures.

I can't wait to see these pictures and see what you think of them.

Hi there....

Does anyone know if Sanjay or anyone else was able to test the lumen output on the Catalina Aquarium MEtal halide bulbs.....

either the mougl or the HQI......

Catalina Told me that they sent bulbs to Sanjay.....

bourbeaue · #**339** 01/06/2006, 08:40 AM

Would two 250 retros be enough for a 72" mixed reef tank and what reflector, ballast and bulb would you recommend ?

Thanks for the advice.

I have not recieved any lamps from them yet.. other than the one 400W DE I picked up in Miami this last week.

It will take a while before I will get to them given my current back log of lamps and other real work.

Yes, that would be enough for a mixed tank.. especially if you layout your rockwork according to the light distribution.

As for recommendations.. you are on your own, but you have access to the data to make your decision

mwood · #**342** 01/14/2006, 04:22 PM

Sanjay, have you thought about adding a max Spectal Irradainance at a wavelength to your tables on the website? Kind of like a KS statistic is given. It would be most usefull on 20k bulbs around the 450 nm range. A person could view ppfd and the 450 nm spike from the tables in choosing thier next bulb.

An example might be EVC 400w 14k on a blueline looks to be about 1.9 watts/nm/m^2 at 452 nm.

Sanjay · #**343** 01/15/2006, 10:02 PM

There is a lot more that can be done with the website and graphs, but right now I do not have the time nor the skills to make it all it can be.

Sanjay

Sanjay · #**344** 01/15/2006, 10:04 PM

I just updated the site with the lastest results of the 175W lamps that have appeared in my last 2 articles. 80 more spectral data have been added.

Sanjay, what are you wanting the site to be able to do/show?

Hey Sanjay, I really appreciate the work you do. Iâ€™m thinking about placing a single 400w halide over a 4â€™*4â€™ area with a LAIII or a lumenmax. Can you respond if one reflector creates a broader spread than another?

Same here I would like to see how the two look in numbers.

I sent off the article with the data on Lumenmax reflectors to Advanced Aquarist. So it should appear on feb 15th.

The short version is, is that the lumenmax puts out the same amount of light as the Lumenarc, but the peak values are slightly lower than the lumenarc. So basically, you cant go wrong with either one. The lumenmax is slightly bigger in dimensions.

Lets make a list of features that people would like to see added to the site.

timr · #**350** 01/18/2006, 08:21 AM

Sanjay, this might already be somewhere on the site or here but can you post a Reader Digest version of what each of the parameters listed mean and what you should ideally look for in a bulb. I've looked at the site many times but when it comes to the different spikes, PPFD, efficiency, etc it gets confusing to us lighting technology rookies.

Thanks,

Tim
