I am only giving this 3 stars not for the product itself just wasn't what I was hoping for. The light itself is great but it just wasn't bright enough for a front porch light which I was seeking. It would have been great with a few more mounted down a sidewalk but for a porch light that I was hoping for to really brighten up the area at night it just wasn't bright enough and the bulb is not replaceable. The light is sealed.
