This article exudes quality. I use outdoor lighting for the entrance equipped with a gate. I feared a lack of power but it is not. The power is in my opinion, in the 400 watt halogen equivalent. I can make this comparison because I have other halogen projector. The price is very reasonable 30. I advise to replace a 500W halogen. I made an indirect illumination test on my terrace it works great I think buy another when my current halogen make the soul.
