do you have a picture with the 20K halides on?
Just missed the MH period today. I can snap a picture tomorrow (if I remember), although the iPhone won't capture the color accurately. It is kind of blue. JP

The Radium looks too blue because of the low wattage of the Reef Brite ballast, not only because of the LEDs.ok. Thanks. I have used Radiums in the past and I am sure that a Radium with the LEDs would be too blue for my taste. The Giessemnn bulbs run quite a bit whiter than other bulbs with the same kelvin rating. IMO the Megachrome Blue 21.5 looks like a 14K. If I do have to go to a Reefbrite, I think I will start with the 14K.

If you offer a better wattage to the bulb it will look more like it should. The best performance is using the M80 magnetic ballast.

Yes, of course.I know for me, the draw of the Reef Brite fixture and ballast is about saving on electricity costs and heat. Running a radium to spec defeats that entirely. I personally have no interest in running 330 watts to power a 250 watt bulb, regardless of the look.
Maybe it's been posted before but where has it been stated that life of the Radium will be reduced to six months if underdriven?Yes, of course.
I like the savings and as I put many times before, the heat here summer time is killer!!!
But I look into having the bulb running a little more than 6 months with a more stable spectrum using the Luxcore as my preference.
It's just a matter of balancing and choosing what we want, right?
The Luxcore will give me a bit more wattage and longevity of the bulb.
I'll get the Spectra if I set up a new system!
We all gonna have halides and that is great!

I know about the heat of the Spectra. People say the solution is to run a fan between the water surface and the fixture.If you don't like heat. you won't like the Spectra. That is what I was running the Radiums on with the Luxcore on HQI. setting The Radium is still pretty blue on HQI. I can't comment on the life. The fixture gets so hot I only ran it for a couple of months. I just can't see how the Spectra doesn't cook the T5's. The lamps are completely enclosed and there is no active cooling. Having run both a Spectra and now the RB, I can tell you that there is no comparison from a heat output perspective. The Spectra runs much, much hotter and throws off significantly more heat.
Unfortunately Tullio said no to that.Spectra is a nice looking fixture. But I have heard it was a hot one. [emoji3]wonder if you used the Reef brite ballast would help with the heat?
Yeah, I know it's going to be a hot fixture already.No Sir - Having used one, I don't think so. The ventilation is the small holes you see on the ends of the fixture.
Yes, I realize it's been said many times...but that doesn't make it true. I would like to see actual evidence of this being true before we spread it around as if it's a fact. My logic is having a hard time understanding why something underdriven would end up with a shorter lifespan. Overdriven? Absolutely, that makes sense.I forgot, but has been said many times...
I think there was an article about it?
The main thing is: the lower wattage, spectrum of the bulb will be bluer and far from what was supposed to be with the M80.
The input power of Reef Brite ballast is 255W.

The electronic HQI setting of the Luxcore is 300W and it's very close to the M80 at 330W.
If I choose the 250 setting on the Luxcore I will save more electricity than the Reef Brite and will be 245W.

I agree with you that overdriving the bulbs would makes more sense in regards to shorten it's life.Yes, I realize it's been said many times...but that doesn't make it true.

I understand the color shift at different wattages as well. It's the life of the bulb I am more concerned about. I do not find the Radium too blue on the RB ballast. But..everyone's taste is different in that regard.
Boom corals has the Spectra and said it's very well built.
I've been talking to many and, not all, but the majority loves it.I can't argue with that. Well designed would be where I would not agree. I would not buy another one. Used or new.
