Complete Lighting Systems

Any suggestions as far as what lighting systems are the most efficent with the best coverage overall? Ive been through the site and i like how xcrispi does his setup with the cool tubes with dual 1000w HPS side by side. Where can I go about purchasing the cool tubes with a complete system? Any tips or advice from you OG growers leme know whats up!

I prefer cool tubes with an added bat wing reflector or something, or enclosed hoods with reflector built in. You can get the lights much closer to the plants this way, which is extremely important for high yields. You can buy them anywhere hydroponic supplies are sold. On line or otherwise.
