As detailed in the listing and previous reviews, it's as easy as screwing in a lightbulb. We'll never know if it actually lasts 40,000 hours. . . Return to 2039. Arms folded down or at a 90 degree angle (throwing light to the floor). Not perfect, but not critical either. Those looking for natural or soft white light more typical of living spaces should look elsewhere. LEDs are more industrial - more of a bluish "daylight" hue than a yellow or cream hue. It takes some time for your eyes to get used to it. I used to have the only "daylight" in the same room and I had to throw it away because it just wasn't strong enough (my garage looked like a Soviet interrogation room). These are MUCH brighter.
