Similar in design, but the ball clamps are much more secure and I haven't had the need to tighten and readjust the light houses since I switched to them.

The power outlet remote switches are a godsend. The light houses are quite noisy (even in standby) and they're mounted in my bedroom so I pretty much have to turn them on and off every day.
