This seems a little more durable than the builder that comes with it. Gasket for watertight closure, frosted lens for light distribution. The springs are insanely taut, the arms aren't as strong as before. Secure half of one side in the jar, then bend the other half so it's under the clip. Now that it's supported on one side you can squeeze the spring with both hands and hook it to the clips on the side of the can. Then press firmly against the ceiling. We switched to LED bulb, much less heat. As a result, the latter failed, when replacing a burned-out light bulb, the plastic burst at the point where the spring was attached, yellowed and became brittle from the heat.
