Lighting Website Updates

[Sanjay]

The lamps tested are the Giesman Marine, Coral and Blue. Whenthey first sent the lamps to me, they said the marine was 10000K and Coral was 13000K. Now I think they sell the Coral lamp as 14500K.

Thank you Sanjay for the clarification.

looking for the CORRECT lighting set-up for my 125 AGA. it has 2 braces on top. rigth now i'm using 3 150 hqi set-ups. what ever it is it would need to be x3. i know this isn't enough light. BTW running phonix 14k's. any help would be GREAT. it seems anything that is half tank or lower just survives but doesn't thrive. specific bulb,reflector,ballast rec. would be great for a newbie like me! thanks to all! john


P.s> this may have been answered. but i couldn't find it. BTW tank is about 19-20"deep not sure how tall. thanks for your patience.

Id just add 2-4 rows of T5s to those existing halides, maybe swap the reflectors for lumenarc 'stealth' reflectors for better penetration. The 150wattDEs can be swapped for a high output 10,000K like the XM/XDE. Then the T5s would be a combo of 2x blue+ bulbs and 2x super actinic bulbs.

The more daylight looking halides have an output that is similar to what many bluer 250watt bulbs have, but the T5s, with all their blue and actinic, will cover up all the yellow. Corals love this combo as well because there is loads of blue and actinic, but there is also loads of daylight... a full spectrum that no halide can provide unless you run 10,000Ks.

The result? A nice 'dayblue' look, almost icey except for a hint of yellow in the output.

For your 125g tank, I would suggest the Icecap 660 ballast, then 3 of the 60" Tek2 reflectors, and 3 sets of endcaps. Then just do two ATI blue+ bulbs and one Sfiligoi Actinic (60" bulbs). The IC660 can run three 5' bulbs on its own then, which is really all you need. The alternative is running a split bank of 3' T5 bulbs (6 or 8x 39 watt bulbs), but the output isnt any greater really, and it just means you have more bulbs to replace every year or so (and 3' T5s cost within a a couple dollars of the 5' ones.

thanks so much for the reply. i'm going to give that a try. thanks again...

One thing about comparing used and unused bulbs of the same type is to keep in mind differences between lots. When GE or anyone else makes bulbs they do not make every lot of bulbs to produce identical light spectrums. When they test them they look at the relative K rating and the relative lums output. If they fall within a set +- tolerance then they are shipped.

You could possibly end up with a used bulb from one lot and a new bulb from a different lot and there difference in K rating initially being so far different that your data now would be considerably misleading.

Even uncalibrated you should be able to check for a spectrum shift. Don;t you have some GE 6500's? If you have a new one and some you've been using you should be able to see a difference if my source is correct. Like I said according to him at six months there is a noticable shift. If you can test used and unused lamps from the same lot it should be the best way to see if there is a noticable shift.

I know the M138 (250w SE pulse start) Ballast is not the best, but can anyone recommend some good bulbs for it?

[rcypert]

Has anyone ever tested those cheap ebay bulbs that run around 10 bucks?

[DrBDC]

I have a pair that I'm not currently using. I was bleaching a bit and decided to go with xm20k's. Since the xm20's are tried and true to work, I don't want to try the ebay ones until my caps recover. I did plug them in and check though. They appear brighter than the xm20's and maybe at a slightly lower kelvin, maybe 15-16,000k. My xm10's were on magnetic ballasts as well and those come out about 11,000k on the test website. I'll try them out better after the caps recover in case the corals start to suffer from lack of a broad enough spectral output then I'll know it was the bulbs. The color of the greatdel 20,000K bulbs are pretty nice though if they have decent output. Even if they are 6 month bulbs, 20 bucks a year is a huge savings.

Sanjay, anymore updates regarding 150w DE MH bulbs, please say yes.

Hello Sanjay , I am now running a 175W M57 ballast with a Blueline 14K lamp . I like the blue look this lamp gives off but I assume the par is in the dumps since the 250W 10K+ not the superwhite blueline is only rated at 33 on a M58
I think Blueline renamed this lamp the 14K now
Since you did not rate the 175W Blueline is it safe to say I will get much better par from a XM 20K 175W with my M57 since when the 250W compare the XM to the blueline is 73 to 33 on a m58?
Thanks

The XM 175W 20K may be your best choice if you like the blue look.

Should I expect much better par & groth since the XM20K 175w gets a 51 PPFD and the Blueline is only 33 PFD for a 250 W

[mile sq. reefer]

Thank you Sanjay, music to my ears, can't wait to see whats new.

Where can I find par values for 250 watt bulbs? I have a 14K Double Ended Phoenix bulb that I'm looking for.

Just spoke to the USIHO gentleman here at MACNA in pittsburght and he said his bulbs have an avaerga life span of 6000 to 8000 hours. That is about 2 years of 8 hours a day. $75 dollars for the lamp 400 watt and it is not to much savings.

Did he say 2 years for quality output? Or until the bulbs go out?

Hello Sanjay
I went to reeflightinginfo.com and looked up Giesemann 10,000k marine bulb with pfo 250w hqi m80 ballast, found ppfd of 88. Did the same for Giesemann coral 13,000k bulb same ballast, it had ppfd of 126. I'M confussed I thought that a bulb of the same manufacture,the one with a lower kelvin would generally have a higher par value.
After further reviewing the web site I went into, all performance data for ballast pfo 250w hqi m80 and found Giesemann 10,000k marine bulb at 129ppfd?
I'm running a 2x250w Double ended Giesemann marine 10,000k and 2x 54atinic ATI bulbs on a Giesemann eco plus fixture m80. Any recommendations on 2x250 d.e. bulbs. Tank size 125 gallon 4x2x2 sps corals. Lighting kept approx. 9 inches from top of water.
Thank You
Kevin

oops

[mrbncal]

So the results on the blv/hit 150 de 10 k bulbs look pretty good to me. How come no one on here runs these bulbs?

[Antman]

Quick question I now use a Aquactinics 175W MH with 2 t5s on my 54 corner tank -This unit sits right on top of my glass hood.
How much light is lost using a glass hood ?
I also may try to lift the unit a few inches of the glass ,how high should it be

[Philwd]

Sanjay - Many pages back you asked for a piece of low iron glass to evaluate as a DE shield. Did you ever get a piece to look at?
