I'd look at the led
's too either the cheap strips as mentioned or maybe some 10w flood lights which are not too expensive either, like $50.
What lights do you have currently?
Here's a pic of my lights controls, so the two switches on the right are the front 2 and back t5 actinics (used in my blue pics above) the left 2 switches are for the moonlight led
, and the fans. The switch for the metal halide lamp is on the ballast.
