Halide Q & A

Yeah 18" is very shallow. The t5ho alone would be fine with good reflectors, but the mh will produce nice shimmer and more color options

18" deep

18" deep

Hello, for an 18" deep tank (48" long and 18" wide) would the 175 watt with a Bali sun reflector be ok? Or should I stick with a 150 watt Cayman sun reflector. I was looking at the new video on metal halides but couldn't find any info on the Bali sun in that video. There will be no t5 supplements. I was also looking at the Bimini fixture but it looked like it would be too much of a focused light. Also I was surprised at how focused the light on the Cayman sun was. I was thinking that a 175watt in a Bali suncwould put out a more even spread than the 150 in a Cayman sun so the par might similar in both fixtures Any experience or comments?
Thanks
 
Yes... the color will shift a bit to the bluer/whiter side and they will put out massive amounts of output.

This is/was a very popular choice for hard core SPS people wanting lots of light or have deep tanks.
 
I don't think they make the xm10k in a 250 mogul base bulb anymore. I tried to find some last year and came up empty.
 
I think I would be willing to try the Hamilton 10K if I were in the market. I know I've been pleased with their 14K.
 
Hi again!
Now I light my tank only metal halide lamps XM 15000K and I like the light. But I'm still in doubt. I read that for the manifestation of all the ATP-coral colors you want to add T5 lamps. But I can not figure out how to arrange them with Lumenbright. Firstly LB bit large for my tank, secondly T5 must have much lower and they will overlap the light from the LBs. In addition, the framework will have to do, and I do not like such a cumbersome structure of the tank. I need advice what to do...

PS: By the way, I have Lumatek ballasts and I did not like how Radium bulbs lights with them. Even in the "Super Lumen" mode I don't see any difference. With magnetic ballasts Vossloh Schwabe the light is much better!
 
Just switched to phoenix heliarc... all i can say is whoa.
Left side phoenix right side 12 k

Just set an SC aquarium 50g cube with a Hamilton 250w 24" Cebu sun, with my low ceiling basement clearance I can only get the fixture 9" off the water.is this too close or will it work ok.

I also am looking for a suitable replacement for the XM 10K bulb - 250w mogul base. I can't find this bulb anywhere either. Is Hamilton the best bet in terms of color and PAR?

I've looked everywhere for the XM 10K with no luck. I think I am going to try the Hamilton 10K or 14K in about a month. I will post my results then.

That would be great. I gave up looking and am now deciding between the Hamilton 10K vs the 10K Ushio.

Do you have T5 supplements? I am considering 10k for growth also and using 4 blue+ so it won't look too yellow.



I'm going to go with two reefbrite XHOs for actinic supplements I think. My biggest concern is that I'll be using a lumenmax elite reflector inside of a "floating/hanging" canopy. The thing has to be mounted so high above the tank that I'm worried the actinics won't be effective that far away from the water.
