I'm looking to redesign my lighting to the mini spotlights/down lights and don't have a real handle on the issues yet. Vers, have you worked with the targetable spots at all? I'm looking to set up 3 hide/basking spots with visual barriers and need something that will not have large amounts of radiant heat but a tight focused spot heating. I may be asking to much of the idea but I need to adjust something in my tank to allow multi basking spots/hides/visual barriers (Oh My) ... My thinking is that the small focused lights would put a tight beam of light and heat to a specific location without over lighting the entire area/tank. Is this possible? I need to have it all worked out before I start buying the new system due to funds and can't afford to get into a white elephant I can't use.
