Halide Q & A

Electronic is basically new technology. It is more exact, and it doesn't cause the "humming." Overall, both will work, but if you have a choice between the two I would go with electronic. It seems like everything is starting to switch over to that anyways.
 
anyone use comercial halides on their tank? i have a couple from worj that im thinking about. they are 200W each and use a M136 bulb, which im not sure i can find in 10k ish
 
I've been looking everywhere for a fixture that will hold 2 - 250 MH. I thought I found it finally (Sun Pod 48") but then I seen it runs on a magnetic ballast...!?

Anyone know of a good double 250 MH fixture??...I'm trying to avoid getting a fixture w/supplement (PC or T5) lighting for simplicity and price.
 
How long to leave the light on?

How long to leave the light on?

I have a 40g breeder thats 36x18x18, and a 250w 20000k MH how long should I leave the light on a day? I have a couple zoas and a frogspawn.
 
Anyone using 250W DE odyssea bulbs? I just got a 2x250watt current outer orbit metal halide fixture & I'm trying to figure out what brand & K rating bulbs to run....anyone have pics that they would care to share of 14K or 20K bulbs? I'm thinking 20K Ushio's but wondering if that will be too blue?
 
I purchased a t-5 6 lamp tek light a few months ago. It was working awesome until my tank cracked. I had to replace it asap and the only place in town was pretty limited. Anyways I ended up with a much larger tank. The tank is 48L 24W and 30H. I was thinking 2 250 20k MHs or 2 400s. I am trying to find a decent unit but am having a hard time deciding. I need either 1 unit that has legs or 1-2 units that can hang from the ceiling. Do any of you have any recommendations?

I don't have the fixture yet, but I am seriously thinking about getting an Odyssea 72" 2x250 MH, and PC's fixture. I have heard that I will need to change the bulbs and ballast, but when I get it I will up load and post pics here. Are you running an Odyssea light?
 
A friend of mine needs lights for his 110 Extra Tall 48x18x31.
Would 2x24" 150watt MHs with T-5s be enough, or would he need 250watt MH's.
Thanks.
 
I just ordered a Giesemann Infiniti 2x150 + 4x54 T5 for a tank with max water depth of 18" at the sand bed.

The tank will be mixed, but SPS dominated - I've been a long time T5 user and I'm just not sure what bulbs to use in which combination.

I want to balance color and growth, but probably lean towards color. I've been considering either Phoenix 14k or Radiums, but I'm not sure what T5's to pair up with them.

In my current T5 fixture I use a Fiji Purple and have used procolor to enhance reds and pinks, so I'm not sure if I can do the same and get good results.
 
Hello All

I live in a remote part of the the world so I am greatly limited by distance and logistics. I am going with a 3m x 700mm deep x 1 metre wide tank. I can't afford to ship a full canopy so I must build my own. BTW shipping a Giesemann canopy after customs is nearly 2K US. I am going to use 5 Dynavision pulse start ballastst and I am thinking of a combination of 3 Ushio Aqualites @ 14K along with two Geisemann 12.5k's.. Lamps are light and they are reletively painless to ship, I plan on ordering double. The question I have is regarding reflectors. These are single ended lamps. No plan for supplemental actinic lighting for now, these are also correctly designated for pulse start ballasts. I don't like the idea of overdriving a 400w lamp as there have been some catastrophic failures, furthermore it seems unwise (unless I am missing something) to apply a pulse start electronic ballast to a probe start lamp? Question? What reflectors would you recommend and "Importantly" will they ship overseas?

Any input would be appreciated.

Best Regards to All

Neil
 
22" hieght on large lumen bright to high?

22" hieght on large lumen bright to high?

22" hieght on large lumen bright to high?
Has anyone done any testing to see when high becomes too high on the large lumen bright reflectors?

I have a mini on my 92 corner right now at about 16" (bulb to water-400w) and have had good success here.

I am constructing my lighting for my new tank and the bulbs are at about 22" from water surface in 3 large reflectors. Wondering if this is getting too high???

65" x 36" tank, i have 3 larges up right now (400w-not running yet) still in construction phase...
 
How do you diagnose if a Electronic blueline ballast is bad? Im new to MH lighting. Just want to know if there is such thing as a bulb tnat a Electronic ballast wont light. When i unplug the ballast it flicks the bulb for a split second. I know the bulb is good. It works with a magnetic ballast. Can i sue a multi meter to test ballast?
