I first bought a similar model from a company that also makes aircraft turbines but it turned out to be much better quality. Additionally, the main benefit of this product is that all the electronics are contained within the unit, so you can install it with wire nuts if you don't have an existing ceiling lightbulb socket. The competitor's light had the electronics in a plug that screwed into the outlet at home, so the outlet had to be installed to use this light. But with this OSTWIN device, you can cut the wires in front of the plug for the lights and just connect them to the black and white power wires in your house with nuts.
