Which light set up would you go with?

[pwnag3!!]

ok... I am stuck between two light setups and i dont know which to get.
1. ARO electronic 150/175w ballast with 150w DE 20k XM HQI
this one just costs $187.90 at a respectable lighting supply.
2. ARO electronic 150/175w ballast with medium base IWASAKI 50K 150w
The cost of this set up is 192.90
I already have a set up of VHO URI 50/50 4x95w on my 62 gallon.
Which do you think would be better?

yeah its 50k .....they say its a bright blue

 

[pwnag3!!]

they are only 9 dollar difference in bulbs

I have never heard of a 50K bulb, I don't think that bulb would work, unless its a typo. 20K is the highest I have ever seen for aquarium use.

its not a typo....type in IWASAKI 50k

Wow, never knew they made a 50K bulb. I don't know anything about them.

 

[pwnag3!!]

yeah its actually suppposed to be more like a 14k bulb.....or so they say

 

[nas19320]

I wonder if thats just a name that Iwasaki gave the bulb, 20K is close to the end of the light spectrum I think, 50K value would be off the chart if not impossible.

 

[nas19320]

I did a little search on -- and apparently the bulbs are visually between a 12-14k.

 

[pwnag3!!]

must be.....its a birhgt blue light

It said...
Also, the 50,000K is nothing special, and looks more like the common 20,000K metal halide lamps out there, as far as visual color is concerned.
I wouldn't trust it, I'd go with the other choice. If it doesn't look any different than a 20K, then why not call it a 20K? Seems wierd to me...
I vote for #1
