Very easy to install. Adequate space to make electrical connections and "store" wires behind panels. Captivated screws make fastening to surface very easy. I replaced a faulty 18" xenon unit (other mfg) and this 12" LED unit make more significantly light. My only complaint is the lack of a multi-brightness switch to allow for a lower step of light without requiring a dimmer on the circuit. [This review was collected as part of a promotion.]
