It has a 250w double ended MH. 4 t5 actinic lamps and 4 moonlights all in one unit. My anemones love it...super simple for me too.

14k or 20 k for ~30 inches deep? Will the 20s hurt certain soft corals? If so which ones?

Doesnít matter. Whichever you prefer. 20k of the same brand/ballast/reflector will be lower par than a 14k. Youíre safe either way

Correct there is no 14k radium. At least not one youíll find on any website selling reef bulbs.

Best bulb is like best skimmer or best salt. People will generally just recommend what they have settled on. Itís impossible to make the claim of best. At this point you basically have pretty limited options

Hamilton
Radium
Ushio
Giesemann
Reef brite

Am I forgetting any? Thereís not near as many options as there once was. Iíll be honest I just use Hamilton bulbs. I have several years in back stock of them as well so Iíve kind of gone all in. Giesemann are double the price, radiums are about $20-30 more per bulb as well. Donít hear much about reef brite bulbs. People seem to like ushio as well but Iíve never used them before.

Radiums paired with an m80 ballast are my favorite looking of the list. Hamilton 20k are in a close second.

This is the "what I like vs. what you like" part of lighting. The MH will be doing the heavy lifting, the rest is just eye candy.

As for me I prefer the 20K 250's Plusrite branded bulbs. When I was running a full reef three of these in lumenbright reflectors were great.

I really love the radiums too, and still have the extra ballasts just in case.

I'd suggest picking up a used fixture or reflector. Try out the different bulbs - You can find them used also. A little shipping. Find the color you like best.

Then decide on a fixture. That used one you bought first will let you experiment with single and double ended bulbs.

M80 ballasts are hard to find these days.

Hamilton Technology has them. And parts to fix as well.

Correct Hamilton has m80
Ballast assemblies in stock and ready to go. The PFO and ReefFlex cube ballasts are all extinct though. Hamilton is hanging in there with the MH gear. You really can get literally anything you need from them and not be left wanting, save for Phoenix bulbs.

My lights on my old 75g tank, 2007-2012, were 2 175w metal halides with 2 36inch t5 actinics for supplemental blue. My preferred bulb on the halides was the Hamilton 10k.


In the pictures are worth 1000 words department, here is a full tank shot from January 2010, and close up of a small section from August 2009 with the 10k halide, t5 actinic combo.

Be very careful of those green Palys. They can kill you. I spent 3 days in the hospital. I won't have them in my tank.

Cadillac Would be what Iím running. Giesmann spectra with Radium B lamps (20K) on a M80 ballast. With T5 and direct replacement LED actinic for supplements. Iím actually running select-a-watt ballasts so I can switch between 250W and 400W lamps with ease.

For dimming, as others have said, I start with the LED, then add the T5 then light the halides one at a time :30 min apart. End of photoperiod the Halides shut down one at a time fallowed by T5 then the LEDs

M80 ballasts can be found used And for free or almost free, but the problem is the igniters go bad and the M80 igniters are hard to find. Hamilton has M80 igniters but they are only rated for 6’ of lamp cord between the ballast and the lamp.

For Radiums or DE lamps you only want electronic ballasts that are HQI or better yet, select-a-watt with an HQI option.
