I have a strip that slots into the lid of one tank and another huge strip that rests ontop of the glass in the other tank, they are fine. I am no expert at installing though, show us pics and we should be able to put it together for you! The tank sounds much better, I have to take lids off when feeding so dont worry! Marina make some good LED spotlights, you may be able to nab one off of Ebay. If the room is very well lit and no real plants then that can do for now, one of my tanks doesnt have a light and gets very well light anyways.
