What's wrong with this lighting system?

[arris138]

I've been doing some research on lighting for my 70gal tank, and came across this lighting set from a website (one that trades in aquatic supplies), and it almost seems too good to be true. Is there something i'm missing in this description, or does this seem like a good buy? I'm still learning about lighting systems, so any help all of you could provide would be greatly appreciated. I'm not too comfortable wiring my own ballasts, and this setup almost seems like it'd be cheaper to buy it premade. :help:
48" 542W Metal Halide System
include two 175W double ended HQI 20000K & two 96W compact fluorescent bulb actinic blue & six LED bluemoon night light
Odyssea metal halide system comes with non corrosive powder coated housing, built-in cooling fans, three on/off switches on external remote ballast controlling HQI, compact fluorescent, and LED separately, tempered glass splash guard, hanging kit and mounting brackets included.
Have it listed on sale for $330.
542W is roughly 8W/gal, so should be ok for some moderately hardy corals as well, right?

hqi is newer lighting and not sure if its proven yet, where metal halide is proven to be the right lighting. there is another guy on the same site that sells mh retro fit kits fairly cheap. power compacts are expensive due to the fact the bulbs need changing every 6 months. where as vho lights last 12 to 14 months before they need changing, just some food for your thoughts, I`ve wasted hundreds on lighting im down to 2- 160 watts vho`s and 3 250 watt metal halides. a seventy gallon wont need that much but that combo seems to be the best in the industry as of right now. good luck.

The problem with those cheaper lights is the halides, power compacts, and moonlights all run off of one single plug..So you don't have the option of giving your tank the dusk to dawn effect. Its like with anything..You get what you paid for.. Just my 2 cents from some personal experience.
