Thanks for the replies.
In hindsight that idea is a bit impractical. I have a bad habit of spontaneous ideas/shopping somtimes.. lol. The reason why I thought of that metal halide was that I would use it temporarily for my plants until I saved enough money for a marine.
But that will take a while. I'm thinking more sanely now
I'm thinking about getting Coralife's 96W 20" lighting fixture:
Energy Savers 20 Inch Aqualight (96W - 4-Tube)
Click to Zoom In
Manufacturer: Energy Savers
Coralife 20" Aqualight™ Deluxe Series - Double Linear Strip with 96 watt 50/50™ 4-Tube (quad) Compact Fluorescent Lamp w/ Square Pin Base and Cooling Fans
96 watt 50/50™ 4-Tube (quad) Compact Fluorescent Lamp Included
Built-in Ballast and Cooling Fans
Sleek Aluminum Housing
Highly-Polished Reflector
Acrylic Lens Cover
On/Off switch
Dimensions: 20" x 7" x 2.5"
Mounting Legs NOT Included
Wondering if that would be practical for plant growth? And is Coralife a reputable brand name? Thanks.
