I was finally able to upgrade my aquarium lighting to Hamilton Technology ~ Metal Halide Lamps 3 x 250 Watt + 96w Power Compacts .
I was told there was a few months left on the bulbs but from tanks I have seen it seems that date has expired.
The system was bought with 2x250w 10k and 1x175w 20k lamps in it along with 2x96w PC attinics
When the attinics are off the tank is VERY yellow , with them on it is more of a white balance with a tad bit of blue.
I am concerned with this since my SPS frags only really seem to like it on the bottom of the tank ( 100 Gallon AGA ) even though the research I have done says these corals should only be placed mid to mid/high in the tank as they need a huge ammount of lighting.
So if a person without a date of first turned on figure out when a MH lamp needs to be replaced ?
