Metal halide people I have a question?

[oreo54]

The tank is still under construction unfortunately. I don't think the XM bulbs are available new anymore. I've seen a couple here and there for sale but they are usually the 20k.

10000k or the 15000k? The ones you have. Just curious.

IIn your previous post you had 6500k grow bulbs linked. Has anyone used these or similar bulbs over corals? The price difference is attractive.

6500k Iwasakis was a "go to" bulb for growth and probably hidden pigments at one time.
Iwasaki seems to have also made a "6500k" bulb specifically for reef aquariums. ReallY A 10000K-ish bulb.
Less yellow.

Bulb Kelvin Rating:
Bulbs come in various 'colors'.
6,500K is yellow, and unpopular. People used them to get fast growth out of their corals.
10,000K is a popular color with good penetration (or PAR)
12,000K is another popular choice, with some blue
14,000K leans into blue.
15,000K is more blue.
20,000K is very blue.

That's not good... you come here again to tease us showing off your ability to make those nice Lumenarc reflectors but don't make any for us??! LOL!

The Phoenix is unique in spectrum, nothing like it. I talked to them, in Japan, a while ago and they won't make them anymore... well... that's what Radium also told me, but they went back in production. Nothing is impossible!
The Radium's color was very similar to Hamilton's 20K, so if Aqua Bright Solutions' bulbs are the same, their 20K should be very similar to Radium.

Alex, could you send me a PM? I'd love to hear your opinion as a fellow brazilian reefer
