I am trying to find out what bulb I should order for my planted aquarium. I purchased a system on ebay that came with a 250w 20k bulb. I know this doesnt really work with plants. How does this one look to everyone? I don't have a lot of money, but this bulb seems to have a lower CRI rating at 65. Is that really poor? Any other options out there folks? http://www.1000bulbs.com/250-Watt-Metal-Halide-Bulbs/38553/

I would really love some help explaining what is most beneficial and if it is even possible to get a decent price on these bulbs or if I just have to spend $80 I need to replace one.

This bulb is not really full daylight bulb, color rating below 5000k, for planted tank the most suitable bulb would be from 6500K to 10000K, this bulb will be too yellowish for the plants.Coralife makes 6500K bulbs would cost around $40.00.8000K bulb or 10000K daylight bulb would cost around $50.00.
