They were easy to install and most importantly the spring tension provided just enough pressure to keep the frame of the light close to the surface. Also, they are square, which is a big plus. Aren't you tired of those round lanterns? It's like the shops don't have a choice. Also, the price for them was quite low at around $25 for 6 bulbs. They give a nice, fairly neutral color output AND the pediment can be rotated 360 AND tilted around the X/Y axis! Easy connection and BAM! You have great lights! Yes, dimmable with the correct Lutron switch.
