I was about to buy for my new 125, but wife decided that we should buy our house first.
Any other types of Led's for around that price or a little more?
Is a 30 gallon sump big enough for a 150?
The three big 'name brand' LED's for a tank that size would be the EcoTech Radions, the AquaIllumination Sols, and the Maxspec Mazzara
There is also at least one person running the Fin-sanity fixture, and several with the Chinese knock off fixtures you find on Ebay
Personally, I would stick with something that has built a reputation as being a reliable fixture - if you're keeping a reef tank lighting will be both your most important, and expensive investment in the hobby
