Was using the same lighting the last time for my 5 footer too but if the lights are switched on for too long, the timer/control box will need to be replaced. Replaced mine twice before. So to prevent it, you'll need to change the fuse to a higher amp. Can't really remember what are the amps of the fuse to use but you can give the agent a call. They were the ones who advised me the last time. Overall the light set is still nice
