Radiums vs. Non Radiums.

IMO: Radiums suck.
What I do not like about them
1.) They only fire on particular ballasts
2.) Corals at the bottom of my 24" tall tank are losing color
3.) The bulb is small. About 3" smaller than my Reflux
The only think I like about it is the color. After the life of these are gone, 4 more months, I will be changing back to Reflux.

Mugul socket- cannot beat reeflux 12k.
De HQI- Jebo/ Odysea, makes bulbs comparable to ushio, for like $20.

I love Radiums! LOL! I have to keep my light sensitive corals off on the side of the tank in my aquarium. I have sps on on all levels of my tank and my par is higher than any other bulbs I have used. I am using the lumen elite max reflectors though so that could help.
The reeflux bulbs are pretty poor par wise, I wouldn't even put them in my top 5, and I'm using one over one of my tanks right now. It will be replaced with something else... Also, I HIGHLY doubt that the Odyssea bulbs can come anywhere near an Ushio bulb, what makes you say they're comparable? Do you have anything to back up that claim?
1.) They fire on any electronic ballast and HQI, which isn't all that limiting IMO.
2.) There are a lot of factord invoilved with coral color, lighting just being one piece of the puzzle. I've seen plenty of tanks running radiums with very colorful corals on the sandbed.
3.) Not sure why that would matter.... The size of the bulb isn't going to determine intensity levels in any way.

Radiums are nice but currently most of my stuff is double ended. I like the phoenix has anyone used the newer mogal phoenix that is around? just wondering
yes the cost is justified IMO. i use nothing but 250 and 400 radium SE bulb and i love them. never had a problem and been suing them for nearly 8 years now. after trying every bulb and balast combo i could think of these are the bulbs i chose to stick with.

hmm...Sweet!
I've seen TONS of different combo's in person (probably 75-100 different tanks) and I have to say my two favorite lighting setups are:
250w = DE Phoenix
400w = SE Radium
I'll be going with Radiums on my new tank.
I've also read the stats on par and both of these bulbs have great par #'s.
After asking hundreds of questions myself, the majority are happy they switched over to them.

I am running radiums on a dimmable Lumatek ballast and Lumenmax Elite reflector. Was using de 250 before. Had to leave the ballast on the 150 watt setting, as the 175 was roasting some of the corals. Gonna have to work up to 250 and then the overdriven setting. I think the radium on a dimmable ballast is the way to go.

I run 2 250W Radiums on Coralvue dimmable ballasts. My tank dimensions are 60x24x25. I use 2 large Lumenbrite fixtures. I grow LPS (Chalices / Acans) and Montis on the sand bed no problem.....
1.) ANY bulb should only be run on the ballast it was designed to be run on anyway. Radiums need to be driven by an M80 for proper color, intensity and life span.
2.) Are you running them on the correct ballast? What reflectors are you using? Are these light demanding corals that you are trying to grow on the bottom?
3.) Who cares? That's what good reflectors are for.
I run Radiums with M80 ballasts in LumenBright reflectors. They are hung 20" above the water WITH glass shields and pond netting (to keep the wrasses in). I've still got 360 PAR at the bottom of a 24" deep tank. Don't blame the bulb for your poor performance if you're not using it properly.
As for the cost, they can be had for less than $70 here;
Metal Halide lighting provides high output light that closely recreates the shimmering effect of bright tropical sun over a patch of coral reef.
