I fired up some Radium SE 250's running icecap ballast for a couple hours yesterday and my corals looked awesome except it was too blue for my taste and not as bright as I wanted, I know they probably would change a little after some break in time but don't think enough. So what I want to find...

I am ready to replace my 20k 250 watt metal halide bulbs. I was wondering if anybody knows what bulbs would give me the best color on a magnetic ballast? I am looking at 20k-24k. Thanks, Ryan

I'm looking to start a nano cube and am looking for either a pendant or 20 inch fixture in good shape to light it, either 150 or 250 watts would be great. I have a couple of t5 fixtures - I'd be willing to potentially trade either one. I have a 24 inch Aquatic life 4 bulb fizture or the 48...

Looking to buy 400w XM bulb what would be the best K value? Looking for a blue tint to make colors pop but still want a clean crisp light.

I am tearing down my full setup...Not enough time or energy to properly care for the setup. Here is what I have and the pricing. Of Course I need to sell the Liverock first then the rest can go! Here is the list. Please let me know if you have any questions. OPEN TO OFFERS on any of this...

Well like the title says, I am looking for different 150 watt 20k de bulbs. I am especially looking for the xm20k and the radium 20k..... I currently run a hamilton 14k, it is just to white for my taste.. I want to buy used but not quite used up bulbs, so I can decide what bulb I like best... It...

ok there are many brands of MH bulbs out there and I want to hear your opinions on which are the best. of these types which are the best 10K bulbs? Reeflux ushio coralvue xm hamilton ice cap thanks in advance for your opinions.

First, I've been struggling with algae (kind of a green slimy type) for the last several months in a well established, 7 year old tank. I've reduced feeding somewhat and clean rocks twice a week to no avail. My phospates read zero, but this could be due to them being consumed by algae. My...

Switching from VHO actintic white to metal halide, I like the actintic look but want good growth rate as well,there will be no supplemental light for now, should I get 14k or 20k bulbs?

For Sale: Two 250 watt retro halides complete. Hamilton ballasts, spider reflectors, all wiring, mogul bases and xm 20k bulbs with 10 months use at 6 hours per day. Everything looks and works as brand new, besides the obvious use on the bulbs. $ 100 a piece or $175 for both. I will ship at...

Need the experience of those that have played the lighting game before. Currently I have a 180 with two 250w xm20k on hamilton m58 ballasts supplemented with 2 6' vho actinics on an icecap 430. The color is good, maybe a tad too blue but very nice to look at. The tank though is dim, shadowy. So...

I've been looking at some member tanks online and absolutely loving the colors they are getting out of their T5 lights. I've been running MH -anywhere from 14-20k-- with all different supplements -- VHOs and T5s of various brands -- and have never come anywhere near the color I would like. In...

Is there anyone out there with a well designed metal halide system that would like a PAR reading on their tank? I bought a PAR meter a while back and wanted to compare MH readings to my well designed T5 only setup using icecap ballasts. Specifically, I would like to measure a system using...

would like opinions on these bulbs. gonna be getting one or the other from deb at diy. looking for great blues plus good intensity and longevity.

Don't give me any crap about the tang or I will have you arrested! Also, you have to click the little "HD" for the clearest view.

i may be buying a used 200g acrylic tank with stand and canopy, it comes with two 400w MH lights, will that be enough lighting for the tank? (right now i only have zoos mushrooms and LPS) looking to get sps in the tank after the switch, and i plan to add supplemental lighting (actinics) also, i...

So another thread about bulb choice.... Here we go. I am trying to decide if I want to keep the current combo of 250w mh with xm20k moguls on m58 ballasts with vho actinics or switch to xm10k with the vho's. The 20's look nice but just a slight bit too blue/dim. They also seem to "wash out" some...
