Easy to install: Yes, for the most part, because if has a few different ways you can mount it and the instructions are not very good and it can take a few test assemblies to figure out how to assemble it right for your application. Once you figure it out then it was very easy to install. I mounted mine to a metal building and used a "pancake" light mount on the outside and just mounted a conduit adapter thru the wall to avoid making a big hole. You can see that in the images I supplied.
Value for the money: OH, Yes, I could not believe they were so heavy for their size and with the seals it came with were all in the right spots to protect the inside components. Side note - the machining of the light is very tight to say the least so have very little room to play with when mounting. That is great the machining it so good and precise but it can be challenging when mounting and thats why you have to pre-assemble first ti figure it all out before just jumping right in.
Warmth: These lights are plenty bright and there would be no reason why i would get the brighter ones. I got these to be able to adjust the light intensity for each area where i mount the three lights. I love being able to create different looks and brightness levels as needed when needed.
Overall, I am looking for more places to mount more of these lights now because i like them so much. I have gotten so many complements from friends and family on how great they look and how adjustable they are.
