Ebay MH bulbs

[biecacka]

bump for the resurgence in halide bulbs!


and shipping being almost as much as a single bulb!

I used to run 20k 150w DE bulbs I got off ebay for cheap, made by Oddysea. They worked as well as Coralife bulbs and had a better blue imo. Phoenix fwt though.

I recently bought a Radium and put it in the center pendant and its not as bright as the PR bulb but the radium makes my coral pop. I really like the blue 20K radium color though so im biased.

On the other hand the 400W plusrite 20K bulbs are noticeably brighter, and have given me good growth AND I can buy 3 of them for the price of a radium bulb.
Its a tough choice and just depends on how rich you might be feeling when its light changing time. I think the price alone justifies trying one, my fish food costs more...

After a year one of my bulbs turned a bit yellow.

Rebuilt my tank so I finally went LED, its saving my triple the amount of electricity used. I was at 765W and now I'm 250W with complete control of color, and I never have to buy bulbs again.

So you are saying that previously you used 765w and now you use 1/3 of that and have the same spread, par, and results?
What fixture did you end up buying?

The newer ocean revives that are 120W each.

Not even running them at 50% yet after 4 weeks

I have not measured par and it is a 30" deep tank and everything looks great.

Do you think 1 of them would replace my 400watt halide?

No. Not enough experience yet to state such.

I have heard they are similar to a 250W and one would have it turned up to do that.

For me, my 175W had massive growth in a 30" deep LPS tank, so I had no need for anything brighter. I would say I understand lower level lighting better then high level lighting.

If you have SPS on the bottom of a 24" it should do fine but growth may slow down dramatically over a 400W light.

I'm going for saving energy, I even swapped out my Iwaki bullet proof pump for a jebao just to save energy. the pump pays for itself in electricity savings if it last 10 months, it pays for itself.

I ran a 250 on my tank for awhile. Just tried the 400 because I could. So if I want to mimic the 250 one of the led fixtures will work.

Yes. YMMV some people have great success with LEDS, and some people have not.

I believe the trick is starting low and ramping up intensity slowly.

That would be nice to get the same coverage from 1 led as one halide. Even if I had to get the 200 way fixture to light my whole cube (48/48/24) with coverage and comparable par. That would be 1/2 the electric used now. Which would be a welcome sight, not that its a ton but who doesn't like to save money!

2 would work, I have 3 on a 72" and there is a little shadowing with whites on.

I don't mind it though and could by a forth but I would still have brace shadows so for me 3 is OK.

Reefbreeders would be a good light for you, it also adds sunset effects. as to where mine just offer blue and white off and on times

[biecacka]

Yeah I have spoken to Logan about the v2. But the fixtures and the watts they use isn't much of a savings. Hence my interest in 1 unit covering my sps tank.

I'll likely stay with halides for awhile. They are easy. Plug and play

Just ordered a few of these to try out. Now I need to find a u shaped metal halide socket holder, any ideas? I found Hamilton technology has them. Anywhere else?

Weird....so I'm waiting for a new 250 ballast and currently running a 400 watt 10k XM bulb on one side of the tank and a 250 watt 20k pulsrite bulb on the other. The side with the pulsrite has started to grow cyano which is odd. I don have that issue in the tank. Anyone else have this issue, or could this be not related to the light.
