Lighting 120g, limited Budget

[Denis]

I love these pendants, good choice. 2 will be just right.
When you build your rock work, don't pile it up against the back wall, instead build a ridge in the middle as these pendants focus the light into a narrow area.
You'll be surprised how bright these are.
I used to run 2 x 400W SE in spiders with about the same intensity.
Later when you get more money upgrade to VHO actinics.
Acro was selling some Icecap ballasts earlier, check with him.
Have fun.
